Frequently exposed to natural agents such as waves, wind, tides, storm activity, seasonal changes and anthropogenic agents, coastal areas are tangibly high energy environments and therefore subject to considerable dynamics. In order to mitigate and reduce the impacts on these areas, different types of coastal protection systems can be implemented. Rockwalls and breakwaters are the most ordinary structures

HIDRALERTA is a forecast and early warning system for coastal and port regions capable of predicting emergency situations, as well as carrying out risk assessment. The system concentrates on evaluating wave overtopping and flooding scenarios. It uses offshore sea-wave and wind forecast data, as well as tide data, as input to determine wave overtopping at specific locations. The calculation of the mean

Coastal and port structures represent a large economic investment for society during their lifetime. Therefore, there is a need for proper coastal planning and management. In order to do that, wave and current loads must be considered by determining their level where the coastal structure should resist, otherwise they may suffer extensive damage due to these environmental loads. In this study, a new

Dune restoration projects that integrate vegetation efforts with natural, sustainable, and soft solutions have become increasingly popular in coastal communities. Eco-restored dunes have high aesthetic value and are likely to be more resilient to near-surface wind effects and/or minor storms events. However, environmental-friendly restoration strategies still lack scientific insight from systematic

Transitional waters are ecosystems of important naturalistic value and enjoy different forms of protection. They are often subject to the threat of pollution phenomena due to anthropic activities and therefore objects of research for the choice of good monitoring, control and management practices. This study deals with the environmental analysis, conducted with water quality measurement campaigns and

This study presents the benefits of the application of multivariate techniques for the hazard assessment of a heavily polluted marine ecosystem. The study area, named Mar Piccolo, near Taranto city (Southern Italy), is a shallow marine basin located nearby an industrial compromised area, declared by the national government as Contaminated Site of Environmental Interest (SIN) due to the presence of

Between the evening of October 23rd and the evening of October 24th 2017, a sea storm hit the city of Bari, along the Adriatic coast, in the south of Italy, causing widespread damages. Due to the absence of direct observations of wave characteristics, the present paper is aimed to (i) compare the development of the occurred sea storm as hindcasted by ’84 method with the predictions by atmosphere-ocean

Abstract This paper aims to evaluate spatiotemporal variability of the mean sea level pressure trends over the Black Sea using the gridded 40-year (1979-2018) reanalysis mean sea level pressure data from two different datasets. These datasets are the European Centre for Medium-Range Weather Forecasts ERA-Interim with a spatial resolution of 0.25° and temporal resolution of six hours, and the National

Sediment deposition is an issue affecting many rivers. To oppose it, sediment withdrawals are often used. However, this practice can trigger further problems in river and coastal sections but, on the other hand, periodic removal of deposited sediments can reduce flooding risk. Also, these sediments can be used for beach nourishment. Therefore, before carrying out a sediment withdrawal, it is necessary

Steel slags are side products of iron and steel industry and are suitable for a variety of applications. In the present paper, the assessment of the hazard associated with steel slags used as harbor piers backfilling material was performed. The analyses were conducted on 64 samples (soil and groundwater) collected in 17 sites located in one of the piers of Taranto city (South Italy), a highly industrialized

Maritime works often require sediment handling activities such as dredging and disposal, to maintain harbors and channels, nourish sandy beaches as well as to carefully remove and relocate contaminated materials from the bottom of estuarine and coastal areas. Such operations often lead to an increase in the concentration of suspended sediments in water columns, which in turn causes adverse effects

Coastal soil erosion can be recognized as the most alarming environmental issue since, causing shoreline retreat, reduces the area available for plant habitat survival, highly influencing their health status, and, consequently, limiting their ability in beach front properties protection. A deep knowledge of vegetation changes is required to identify the proper strategy to be adopted to face soil erosion

Recent biodiversity surveys in the lentic habitats of Singapore revealed that non-native cichlids (at least 14 species from different origins) were the most abundant species in the reservoirs of Singapore. To understand the diversity and distribution patterns in six reservoirs (two inland and four coastal), we investigated the species richness and abundances of these cichlids. We also investigated

In this study, biocontrol of harmful effect of cyanobacterial blooms and their toxins by “flocculation-biosorption” was achieved. Five fungal species were isolated from decayed cyanobacterial bloom which are: Aspergillus fumigatus, A. niger, Penicillium, Trichoderma ressei and Mucor rouxii. We chose the last species’ pellets because they are the most stable and cocultured with Anabeana sp. (1:5 fungal:

The present study envisages the importance of monitoring and management of freshwater springs of Kashmir Himalaya due to role they play in meeting ever-increasing drinking water demands and maintaining various ecosystem services. Therefore, some of the most pressing issues fundamental to the existence of springs is their monitoring and management because of their geological, ecological, scientific

A periphyton-based index for biological integrity was developed to assess the ecological status of lakes and reservoirs in Baiyangdian Watershed, China. Periphyton and environmental surveys were conducted at 20 sites during 2009-2010. A total of 22 surveyed metrics of periphyton, which were classified into 6 categories: biomass groups, community structure, pigment ratios, bacteria diversity, enzyme

The diatom Didymosphenia geminata can produce thick benthic mats along river bottoms, possibly in association with soluble reactive phosphorus mat-forming genetic variants, or gene expression associated with environmental variation. We isolated cells collected from mat-forming and non-mat-forming sites in British Columbia and Alberta, Canada and compared soluble reactive phosphorus, frequency of dividing

This study investigates the relationship between macrobenthic functional group composition and hypoxia in the Changjiang River estuary and its adjacent sea areas. A total of 82 stations were divided into three areas, named non-hypoxic area, hypoxic area and the Changjiang River, respectively. A total of 256 macrobenthic species were collected, which were divided into five functional groups, including

The coral reef ecosystem plays an important role in scientific research and economy. An assessment research on status of the coral reefs was carried out at 6 sites of coastal water from Nghi Son (Thanh Hoa province) to Vung Ro (Khanh Hoa province), Viet Nam between October and December 2015. The research was done using the manta tow method for rapid reef assessment and reef area determination, using

This study assessed the effects of different electric current densities on the calcification and photosynthetic physiology of a massive, colonial stony coral species. Coral survivorship, calcification rate, and photosynthetic parameters (zooxanthellae density and chlorophyll fluorescence) were measured to determine the physiological and photosynthetic performance of Galaxea fascicularis after exposure

In this study, a protective seed core method for planting seeds of the common eelgrass Zostera marina was developed and evaluated through laboratory and field experiments. We studied the suitable desiccation period of the protective seed cores, and their effect on seed germination and seedling establishment in a laboratory experiment. New patches established by seeds planted with the protective seed

Rehabilitation efforts for Lake Trout Salvelinus namaycush in Lake Huron have resulted in increased capture of young wild Lake Trout in annual bottom trawl surveys conducted by the U.S. Geological Survey. To better understand the ecology of juvenile (<400 mm) Lake Trout, we summarized the spatial distribution of their capture in bottom trawls at six ports in Lake Huron during October/November 2008–2017

Escalating pesticide deposition in the aquatic environment is becoming a potential threat to aquatic organisms.

Globally, human development has proceeded at a rapid pace for the past several decades for both terrestrial and aquatic/marine environments. Project developers, government decision-makers and the public have had little data regarding the relative values of natural resources, or losses thereof, to facilitate project – and corresponding natural resource takings/ecosystem degradation – decision-making

The Arabian Gulf is exposed to intensive dust storms during summer until early winter. We investigated the nutritive effect of the dust on microbial biodiversity of the water column and the productivity of the Gulf. We collected samples from three sites in a transect perpendicular to the shore in March (before the strong dust storms) and in October (after the dust season) in 2013. At the three sites

The study provides an assessment of sand dredging activities from the bottom of the sea during 2016 in the Kingdom of Bahrain. Total Suspended Solids were analyzed from 2010 until 2016 in the northern and eastern locations according to the Manual of oceanographic observations and pollutant analyses methods. Fifty five percent of sand dredging companies complied with some legislation such as air quality

The purpose of this research was to (1) identify an existing water quality index methodology that could be used in Abu Dhabi, United Arab Emirates, and (2) apply the water quality index to Abu Dhabi’s waters to communicate water quality conditions and track changes in conditions over time. The available monitoring data were reviewed to establish the types and frequencies of data available to populate

Abu Dhabi, the capital of the United Arab Emirates, has a coastline that occupies 76% of the country’s Arabian Gulf coastline. The pressures accompanying the economic development that the country is undergoing ultimately affected the marine ecosystem including water and sediment quality. In order to protect the marine ecosystem and public health, the Environment Agency- Abu Dhabi developed ambient

Coral reefs in the southern Persian/Arabian Gulf have become increasingly degraded in the past two decades, mainly due to recurrent mass coral bleaching events. The recovery of these reefs will be largely contingent upon the arrival and settlement of coral larvae and their post settlement growth and survival. Spatial and temporal patterns of coral settlement were quantified on 10 sites spanning >350 km

Human activities and coastal development driven by economic growth in countries bordering the Arabian Gulf have increased marine pollution, including eutrophication. In response to growing concerns, the Environment Agency- Abu Dhabi initiated a long-term monitoring survey (2006 to 2019) to study the marine water quality of Abu Dhabi, including the Mussafah South Channel (MSC). This confined area is

The maintenance of coral reef framework results from a balance between skeletal accretion and bioerosion, and this balance can be disrupted by environmental stress and disturbance. Coral reefs in northeastern Arabia exist in extreme environmental conditions and have experienced severe disturbances in recent years. This study assessed the intensity of macrobioerosion in two regionally common species

Kuwait, which is located in the northwestern Arabian Gulf, has experienced several incidences of marine life mortality during the past two decades. Mortalities included pelagic and benthic fish, Sea Cucumbers and Mollusks including pearl oysters. Most of the mortalities occurred in Kuwait Bay, which is shallow and semi-enclosed. The Bay encompasses Sulaibikhat Bay, whose coastal waters are nutrient-rich

Species-specific biological data are commonly combined with fishery operational data to model exploited stocks and determine appropriate levels of exploitation. However, this approach to fishery management is predicated using the' to 'predicated on the ability of fishery data collectors to correctly identify exploited species. Sharks and other elasmobranch fishes (Elasmobranchii) can be particularly

Seabirds form important components of marine ecosystems, serving as top predators that indicate long-term stability through feeding interactions. Many species of seabirds reside within the Arabian Gulf although their role in this marine system is not well characterized. Furthermore, oil exploitation and development activities have reduced many species significantly. In this review, I use the Socotra

The Gulf (or Persian Gulf) suffers from multiple anthropogenic stressors relating primarily to its position as the centre of the global oil industry. Environmental degradation including oil spills, loss of coastal habitat, algal blooms and invasive species is evident but finding the right approach to address such degradation is challenging. The North American Great Lakes faced (and continues to face)
