Socio-hydrology has recently garnered attention as a promising research paradigm among hydrologists. In this paper, we argue that viewing the socio-hydrological systems as a network of causal factors can assist in these efforts by revealing emergent properties of socio-hydrological systems. These factors, which are neither actors nor affiliations but symbolic representations of miscellaneous phenomena

Abstract This study investigated the impacts of climate and socio-economic changes on water resources in the Beas-Sutlej River Basin, Himalaya. Multiple-model ensembles of five climate models forced with the RCP 8.5 scenario and the Shared Socio-economic Pathway SSP 1 were used. A validated Water Evaluation And Planning (WEAP) model of the basin was used for assessing the resulting sectoral water allocations

ABSTRACT Evaluating localized impacts of water allocation scenarios (WASs) is an important multi attribute water decision problem. These impacts of WASs are not the same within a basin and they have their own spatial variations. Conventional multi-attribute decision making (MADM) is not capable of capturing and implementing the spatial variations. Using these methods often results in simplicity and

This study describes the impacts of refinement of hydraulic geometry (HG) relationships in the hydrological MGB model applied to an Amazonian sub-basin (Purus River basin). To this end, HG relationships were developed for the entire basin and for hydrologically homogeneous regions, and their performances were compared with observed data and a global width and depth database. Two simulations were then

ABSTRACT The Mediterranean region is a climate change hotspot for water resources. However, uncertainty analyses of hydrological projections are rarely quantified. In this study, an in-depth analysis of projections and uncertainties for high and low flows is performed. Climatic projections derived from a recent downscaling method were used, for two representative concentration pathway scenarios (RCPs)

ABSTRACT An agent-based model (ABM) is developed to explore the socio-hydrological and economic impacts of a water transfer project, as a supply enhancement strategy, on the cap-and-trade scheme, as a demand-side management practice, in Rafsanjan Plain, Iran. The modelling scheme benefits from a distributed groundwater model coupled with a socio-economic ABM to explore the social and economic impacts

ABSTRACT Spatial cross-correlation among flood sequences impacts the accuracy of regional predictors. Our study investigates this impact for two regionalization procedures, generalized least squares (GLS) regression and top-kriging (TK), which deal with cross-correlation in two fundamentally different ways and therefore might be associated with different accuracy and uncertainty of predicted flood

ABSTRACT Although storage-reliability-yield (SRY) relationships have been widely used in the design and planning of water supply reservoirs, their application in hydroelectricity is practically nil. Here, we revisit the SRY analysis and seek its generic configuration for hydroelectric reservoirs, following a stochastic simulation approach. After defining key concepts and tools of conventional SRY studies

ABSTRACT In many areas around the world, phreatic coastal aquifers are vulnerable to contamination and saltwater intrusion. This study aims to explore the hydrodynamic functioning of the coastal phreatic aquifer of the Urabá region, Colombia, based on the identification of hydrogeochemical processes and groundwater residence and transit times. Hydrodynamic data showed a fast response of the piezometric

ABSTRACT The main objective of the present research is scaling lognormal water retention curves for dissimilar soils. This method requires a reference curve and the amount of water content in a particular suction. The scaling factor in this method equals the log amount of moisture in a particular suction (e.g. Se5000) in the reference soil to the log amount of water content in the same suction in the

ABSTRACT Mountainous regions are a hotspot for water scarcity and anthropogenic pressure on water resources. Substantial uncertainty surrounds projections of future climate and water availability. Furthermore, quantitative and distributed data on water demand are generally scarce, dispersed, and highly heterogeneous. This forms a major bottleneck to studying water resources issues and developing strategies

ABSTRACT Land-use/land-cover (LULC) changes in the Gidabo basin, Rift Valley, Ethiopia, have greatly affected the hydrology of the basin. This study integrates hydrological modelling with statistical analysis to evaluate the hydrological response of LULC changes during the period 1988–2018. Using the Soil and Water Assessment Tool (SWAT) and partial least squares regression (PLSR) models, the influences

ABSTRACT In this study, advanced scatterometer (ASCAT) soil moisture data is employed to compute the basin water index (BWI) over six river basins of India for 10 years (2007–2016). The BWI time series is assessed for the development of its relationship with observed streamflow. Further, a popular ensemble learning technique, random forest, is employed to compute the 10-d streamflow using the BWI time

ABSTRACT This study assesses the seasonal forecast skill of river flow persistence in 46 catchments representing a range of hydrogeological conditions across Ireland. Skill is evaluated against a climatology benchmark forecast and by examining correlations between predicted and observed flow anomalies. Forecasts perform best when initialized in drier summer months, 87% of which show greater skill relative

ABSTRACT This study investigates the uncertainty in hydroclimatic modelling chain components on future changes in potential evapotranspiration, specially on low flows, at the watershed scale. A large domain covering 2080 watersheds located in Canada, the United States and Mexico is studied. The outputs from eight global climate models are post-processed using two methods to produce climate scenarios

ABSTRACT Streamflow recession analysis is widely used for estimating catchment-scale hydrogeological parameters in gauged catchments because of its low cost, ease of use, and efficiency in terms of results. In this work, however, the same methodology was applied to ungauged creek catchments, where low recession flows were simulated using physically based, semi-distributed, continuous hydrological modelling

ABSTRACT Extraordinary flood events occurred recently in northwest England, with several severe floods in Cumbria, Lancashire and the Manchester area in 2004, 2009 and 2015. These clustered extraordinary events have raised the question of whether any changes in the magnitude and frequency of river flows in the region can be detected. For this purpose, the annual maximum series of 39 river gauging stations

Abstract Accurately quantifying transpiration (T) in apple orchards and its proportion of precipitation (P) is important for comprehending hydrological and ecological processes. A field experiment was conducted during the growing seasons (May to September) of 2013-2016 on the Loess Plateau of China to investigate the characteristics of T in apple (Malus domestica, cv. Fuji) orchards of different ages

Eddy covariance (EC) systems are expensive and not financially viable in a budget-restricted hydrological monitoring network. The surface renewal (SR) method is a cheaper alternative that requires a reduced fetch, but is currently dependent on EC for calibration. The SR methods not requiring calibration (SR2 and SRDT) have been used, but are not widely tested over indigenous vegetation. The aim of

Abstract We developed a simple conceptual socio-hydrological model to explore the mutual interactions between water management systems and society. We examined the feedback among climate, population, wealth and water availability and capital investment. Given the focus on the interplay among these multiple variables, some simple schemes were designated in order to simulate rainfall inputs, surface

ABSTRACT Predicting the impacts of projected change in precipitation (P) and temperature (T) on occurrence of drought and extreme events are essential for managing natural resources and setting policy. This study compares future occurrence of excessively dry and wet periods based on P, T, stream flow, soil moisture, and extreme P and T events. The comparisons are based on coupled future climate projections

ABSTRACT Understanding how human and water systems co-evolve is a vital step towards achieving sustainability. This paper presents a historical socio-hydrological analysis of a semi-arid and overexploited basin in Eastern Iran, which is currently experiencing a serious water crisis. The co-evolutionary history of the socio-hydrological system within the basin was divided into three phases: natural

ABSTRACT The size-dependent chemical maturity of sediment cycling in a high-altitude glacial/periglacial environment was studied by examining the sediments of the Chorabari Glacier, Mandakini Valley, central Himalaya, India. Sediments evacuated from glacial debris and a periglacial area were studied via particle-size analysis, X-ray fluorescence, and X-ray diffraction of different grain-size fractions

ABSTRACT The farmers in the Bow River Basin (BRB), Canada, have adopted water conservation strategies to reduce water needs. This reduction, however, encouraged the expansion of irrigation, which may rebound agricultural water demands. This paradox requires an understanding of human adaptation to drought by mapping individual farmers’ water conservation decisions to the dynamics of the basin-wide water

ABSTRACT Predicting future water demands of societies is a major challenge because it involves a holistic understanding of possible changes within socio-hydrological systems. Although recent research has made efforts to translate social dimensions into the analysis of hydrological systems, few studies have involved citizen participation in water footprint analysis. This paper integrates time series

ABSTRACT Bayesian hierarchical models have been increasingly used in regional flood frequency analysis due to their flexibility and ability to accommodate the spatial variability of flooding processes in distribution parameters. Hierarchical models based on the generalized extreme value (GEV) distribution are useful since they may combine scaling properties and distinct degrees of pooling in the shape

ABSTRACT The wise selection of modeling approaches with an appropriate level of complexity for the study objectives is critical for robust inference. In this paper, the structure of a cost–performance grid designed for flood modeling is presented. The grid is developed to compare different flood modeling approaches of variable complexity and to provide guidance on the proper selection of the data-model

ABSTRACT Relationships between surface waters and groundwaters at basin scale are rarely investigated but have important implications for water resource development and management. Here, we integrate evidence from geochemical tracers and piezometry to advance the understanding of regional-scale, groundwater–surface water interactions in the River Awash Basin of Ethiopia. Hydrological characteristics

ABSTRACT Groundwater resource overdraft is a serious water resource concern worldwide. Although afforestation has been recognized as conserving water resources, improving water quality and mitigating river flood, the role it plays with groundwater resources is not fully investigated. Here we applied the US Geological Survey’s Mississippi Embayment Regional Aquifer Study (MERAS) model to estimate impacts

ABSTRACT Resampling historical time series remains one of the main approaches used to generate long-term probabilistic streamflow forecasts, while there is a need to develop more flexible approaches taking into account non-stationarities. One possible approach is to use a modelling chain consisting of a stochastic weather generator and a hydrological model. However, the ability of this modelling chain

ABSTRACT A distributed hydrological model was applied to a 69 km2 experimental catchment, Eddleston Water, Scotland, UK. The impact on model outputs of applying progressively simpler representations of spatial variability in land use and superficial geology was assessed. Alternative representations of the spatial distribution of superficial geology and land use produced differences in model outputs

ABSTRACT Climate change impact search methodologies, for a single hydro-meteorological record, are based mostly on probabilistic, statistical and stochastic processes. The application of these methodologies requires some restrictive assumptions for their validation, which may not be embedded in the structure of the record. Either transformations or approximations are taken into consideration, with

ABSTRACT The association of hydrological models with remote sensing data allows the estimation of parameters that cannot be easily measured in situ, especially in regions with poor monitoring networks. In this paper, a distributed hydrological energy water balance model (FEST-EWB) was calibrated and validated in a basin located in a climate transition zone between a semi-arid region and the humid Atlantic

ABSTRACT This study investigated the differential response to rainfall of soil moisture infiltration in the permafrost area of the downhill slope and in the seasonally frozen ground area of the uphill slope in Kangqiong small basin on the Qinghai-Tibet Plateau. The results show that: (1) influenced by the barrier of the permafrost layer, the suprapermafrost water level in the permafrost area rises

ABSTRACT The storage function model (SFM) is a rainfall–runoff model widely used in Korea for flood forecasting and warning systems. The traditional equations for parameter estimation are based on observed data under limited conditions, and so it is difficult to sensitively consider the factors affecting actual runoff. The aim of this study is to develop synthetic equations for SFM parameter estimation

Abstract In north Gujarat, local communities depend on the Precambrian basement aquifers for their primary source of water supply. The increasing demand for potable water puts stress to explore groundwater from less reliable sources of basement rocks. The main objective is to map groundwater potential zones (GWPZ) in water-scarce Precambrian terranes using integrated multi-criteria analysis (Analytical

In this study, the impact of the recently constructed Chaersen reservoir on downstream baseflow recession is analyzed using the pre-post comparison method. Additionally, the potential causes of these effects are investigated. Reservoir construction is found

Abstract Climate change together with changes in land cover and water allocations are expected to affect water resources availability. The long-term effect of these changes on available water resources in central Chile was comprehensively evaluated through climatic trends from 1982, land cover changes from 2001, and water allocations from 1980. Trends in climatic, land cover and hydrologic variables

Water stress prompts a durable reduction in water demand under some circumstances. This demand reduction has the potential to alter the benefits and costs of demand and supply side alternatives in water supply planning. This paper takes a socio-hydrological approach to assess the implications of this feedback, in the context of Las Vegas, NV. This application demonstrates feasibility first by developing

The cause-effect relationship and rates of change of suspended sediment dynamics at catchment scales in the tropics remains poorly understood. This research used a chrono-sequence of remotely sensed land use and historical hydrometric data from 1985 to 2001 in three tropical streams of Mexico to analyze the temporal dynamics of land-use change and measured suspended sediment behavior. The variations

Abstract Social and hydrological dynamics are coupled, nonlinear, and complex. To clarify and enhance our understanding of such dynamics, we developed a stylized model that combines hydrological and social dynamics of a generic coupled human–water system. In this model, neither too much (flood) nor too little water (drought) is desirable, and the population self-organizes to respond to relative benefits

Understanding the sediment transport characteristic of rivers plays a vital role in the management of water resource projects. The lower Drava River Basin is one of the most extensively hydroelectrically exploited river basins in the world. In this

Abstract Groundwater is continuously and disorderly exploited to a great extent for a prolonged time in the North China Plain (NCP), which leads to severe problems of groundwater over-exploitation, making it the largest groundwater funnel zone in the world. Based on the comprehensive treatment of over-exploited groundwater in Shandong province, this paper analyses and forecasts the water demand, supply

Abstract This paper aims to test different methods used for assessing the indices of sediment yield to identify hotspots and rank sediment yield hotspots. This process includes the assessment of the Entropy Weighting (EW), Fractal Dimension (FD), Slope Length (SL) gradient, and Sediment Connectivity (SC) methods. The indices at different sub-catchment levels were applied in the Ilanlu catchment (Iran)

Abstract Water crises have risen over the past decade. In the Brazilian context, extreme events have been intensified over the country undermining water systems in regions that already face water shortages. Although existing studies focused on individual regions of Brazil, an overview of the entire country will contribute to developing a national action plan for mitigating water inequalities. Therefore

Abstract The advent of GRACE has opened the doors for remote monitoring of gravitational changes and its derivatives across the globe, but received less attention due to poor spatial and temporal representation. Statistical models with varying complexity are commonly employed to downscale the GRACE datasets for use with local to regional applications. This study presents the application of two commonly

Equitable water allocation in the context of local-scale water conflicts can be challenging. We present a holistic framework for the analysis of small-scale water disputes, contributing an integrated approach to the analysis of water conflicts by providing technical solutions combined with an in-depth analysis of social dynamics. The analysis focuses on an ongoing water conflict in El Carracillo region

Accordingly, hydrologists are increasingly working with social sciences and becoming involved in fieldwork with participants. With the overarching aim of facilitating collaboration and interdisciplinary water research, here we discuss

ABSTRACT Disentangling the meteorological and human drivers of drought is a critical challenge. A key difficulty is identifying natural conditions against which human impacts can be analysed. Here, a combination of approaches is used: a hydrological model is developed for an upstream unmodified location and is then applied to a downstream site subject to irrigation-related abstractions: i.e. an up

ABSTRACT This study presents a formula for estimating the mean flow velocity of the Nile River, Egypt. The proposed formula is presented in the form of the commonly used Manning equation. The derived relationship can be directly incorporated into numerical models and used by hydraulic professionals. The formula is developed using a large database of field measurements from the Nile River and its canals

ABSTRACT Accurate modelling of peat water contents (θ) is critical for wetland studies. We modified the Campbell and Van Genuchten soil water retention curves (SWRCs) by replacing their empirical parameters with measurable properties. Combining the water table depth (d WT) into SWRCs, we derived formulae for calculating volumetric θ from d WT, coded in a simple model to test our hypotheses that d WT

ABSTRACT According to simulations, permafrost area in the Tienshan Mountains has decreased by about 1.73 × 104 km2 (or 20.91%) from the 1960s to the 2000s, and the freeze state of seasonally frozen ground (SFG) exhibited delaying freeze, advancing thaw, shortening freeze days and shallowing freeze depth. River discharge has changed largely, especially for winter and minimum monthly discharge. The rivers

ABSTRACT This study aims to analyse the effect of the Arctic Oscillation Index (AOI) on drought indices in northern Iraq. The Standardized Precipitation Evapotranspiration Index (SPEI) for 3-, 6- and 12-month time scales was calculated to determine the behaviour of the meteorological drought for the period 1983–2014. Average drought characteristics were found for three periods: 1983–1993, 1994–2004

ABSTRACT The climatic characteristics of Brazil present marked spatial and temporal precipitation contrasts, which are reviewed according to four main indices: PRCPTOT – total precipitation; Rmm – number of days with precipitation; Rx1day – maximum 1-day precipitation; and SDII – simple precipitation intensity index. The study used data for 12 hydrographic basins from 1975 to 2005. The seasonal distribution

ABSTRACT A new probabilistic conceptual model, named the Assessment Model of Human Impact on Runoff Based on Stationarity Hypothesis (AMHIRBSH), was developed to attribute runoff variations to human activities through evaluating the changes in the runoff–runoff relationship (i.e. that between runoff of different watersheds). The AMHIRBSH was then applied to the Baiyangdian drainage basin, North China
