The Monforte de Moyuela dam, also known as Ermita la Virgen del Pilar is a Roman reservoir built on tributary of the Aguasvivas River (Ebro basin, Spain). A multidisciplinary study has been carried out to investigate this kind water infrastructure. It fifth-highest dam (16.8 m) in Iberian Peninsula and seventh Empire. initial was ca. 100 B.C.–10 A.D., probably period Augustus, like other nearby...

Tidal flats provide ecosystem services to billions of people worldwide; however, their changing status is largely unknown. Several challenges in the fine extraction tidal using remote sensing techniques, including tide-level and water-edge line changes, exist at present, especially regarding spatial temporal distribution mangroves. This study proposed a method combination threshold segmentation...

The article presents the results of analysis deep deformations Amu Darya riverbed in upper reaches low-pressure reservoir. combined transverse profiles different sections Takhiatash reservoir showed that coastal zones are most intensively silted up. At same time, core zone with highest flow rates is very weakly declared. height silting layer along length stream increases direction dam. area ext...

Bull Island (BI) is a coastal sand spit that formed as an unintended consequence of the construction two walls, built over 200 years ago in Dublin Port, Ireland to alleviate silting shipping route. A large lagoon, on land side island was separated 1964 by causeway produce separate lagoons are now impacted different water sources. Here we investigate influence riverine inputs adjacent but unconn...

The article discusses the results of numerical studies flow Amudarya river above point damless water intake to head structure Karshi Main Canal-KMC. system two-dimensional equations hydrodynamics-Saint-Venant is used as basis mathematical model. In this work, a series calculations field currents in channel during low-water periods carried out. Below are main research and proposals for ensuring ...

Abstract Purpose Lake Victoria has been increasingly silting over the past decades, impacting water quality and loss of biodiversity. Sediment control strategies require information on relative absolute contributions sediment from different sources. However, to date, there is no continuous monitoring flux or in any tributaries, prohibiting an assessment scale problem. The aim this study was tra...

Water erosion is one of the main causes soil degradation around world. In M orocco, watersheds have very significant wastes, related to various physical and anthropic factors. The Oued Inaouene watershed concerned because its location in eastern part Saïss basin, between Middle Atlas Pre-Rif, where water more accentuated. This basin covers a total area 3597.13 Km 2 it marked by semi-arid climat...

An excessive amount of bank erosion along a number of waterways in Illinois and surrounding states exists at the present time. Erosion of stream banks attracts public attention, reduces property values, results in the permanent loss of real estate, increases the turbidity of streams, and accelerates the silting of reservoirs and backwater lakes along stream courses. Among the main causes of ban...

There are many reasons to preserve the biological diversity of the earth, and perhaps the most compelling is the insurance that it provides for the uncertain times ahead. The responsibility for maintaining this biodiversity falls particularly heavily on the custodians of the tropical forests, where species richness is highest. How can these forests provide for the immediate needs of local inhab...

The heavy rains in the winter of 2009-2010 in Spain activated all the sediment-feeder systems of a small reservoir built in the 1970s north of the Sierra de Almijara (province of Granada). The intensity of this activity has aided in recognizing a series of geomorphic features allowing the re-interpretation of previous data on the subsoil obtained from Ground Penetrating Radar (GPR) and sediment...
