Natural fractures are characterized by high internal heterogeneity. This internal variability is the cause of flow channeling, which in turn leads to contaminant transport taking place primarily along the high-velocity channels. Mass exchange between the high-velocity channels and the low-velocity zones has the potential to enhance contaminant retention, due to solute diffusion into the low-velocity

Hydrologic exchange processes are critical for ecosystem services along river corridors. Meandering contributes to this exchange by driving channel water, solutes, and energy through the surrounding alluvium, a process called sinuosity-driven hyporheic exchange. This exchange is embedded within and modulated by the regional groundwater flow (RGF), which compresses the hyporheic zone and potentially

Spatial-Temporal Differentiation of Supra- and Sub-Permafrost Groundwater Contributions to River Runoff in the Eurasian Arctic and Qinghai-Tibet Plateau Permafrost Regions Water Resour. Res. (IF 5.4) Pub Date : 2024-03-15 Zhiwei Wang, Shouqin Sun, Genxu Wang, Chunlin Song
Supra- and sub-permafrost groundwater are the two main components of groundwater in permafrost regions. However, due to the lack of groundwater observational data, the spatial-temporal differentiation of these groundwater components in permafrost basins remains unclear. Based on flow data from 17 hydrological stations in five permafrost rivers within the Eurasian Arctic and Qinghai-Tibet Plateau permafrost

Role of Lakes, Flood, and Low Flow Events in Modifying Catchment-Scale DOC:TN:TP Stoichiometry and Export Water Resour. Res. (IF 5.4) Pub Date : 2024-03-15 Christina Fasching, Kyle S. Boodoo, Huaxia Yao, James A. Rusak, Marguerite A. Xenopoulos
The balance of organic carbon (OC), nitrogen (N) and phosphorus (P) plays a crucial role in determining the processing, retention, and movement of these solutes across the aquatic continuum. Floods and droughts can significantly alter the quantity and ratios of OC:N:P export within inland waters, but how these ratios change, and are coupled within watersheds that integrate rivers and lakes, is not

Large-Scale Channel Response to Erosion-Control Measures Water Resour. Res. (IF 5.4) Pub Date : 2024-03-15 C. Ylla Arbós, A. Blom, S. R. White, R. Patzwahl, R. M. J. Schielen
Erosion-control measures in rivers aim to provide sufficient navigation width, reduce local erosion, or to protect neighboring communities from flooding. These measures are typically devised to solve a local problem. However, local channel modifications trigger a large-scale channel response in the form of migrating bed level and sediment sorting waves. Our objective is to investigate the large-scale

Spatiotemporal Data Augmentation of MODIS-Landsat Water Bodies Using Adversarial Networks Water Resour. Res. (IF 5.4) Pub Date : 2024-03-13 Soukaina Filali Boubrahimi, Ashit Neema, Ayman Nassar, Pouya Hosseinzadeh, Shah Muhammad Hamdi
With increasing demands for precise water resource management, there is a growing need for advanced techniques in mapping water bodies. The currently deployed satellites provide complementary data that are either of high spatial or high temporal resolutions. As a result, there is a clear trade-off between space and time when considering a single data source. For the efficient monitoring of multiple
