catchment area level. Analyses on potential impacts of dam construction are not new. However, the approach presented in this study takes the (sub-)catchment and major basin scale into account, a scale that is naturally given by the connectivity of the river network, instead of a single case ...
Dam construction in upstream of each watershed usually change the hydrologic characteristics of that basin and can decrease the maximum flood discharge. Atrak watershed is one of the largest basins in the north east of Iran, with a catchments area of 17687 Km2. During last 8 years 5 large ...
Large lakes are important to buffering the potential impacts of global climate change on local water resources that millions of people's livelihoods depend on. However, abrupt changes in water level from one extreme to another (e.g., flood to drought) over short periods of time have been obse...
Dam-impacted catchments experience higher irrigation pressure and about 25 times more economic activity per unit of water than do unaffected catchments. In view of projected changes in climate and water resource use, these findings can be used to identify ecological risks associated with further ...
" stressed Fengzhi He. Together with colleagues from IUCN, the University of Tübingen and Queen Mary University of London, Fengzhi He describes in this publication which factors pose threats to freshwater megafauna. Besides the obstruction and fragmentation of water bodies following dam construction,...
We predict that bird species recovery will continue to increase for some time before reaching a plateau among the newly created islands, reservoir and catchment area of the dam.Introduction As the global climate crisis continues to worsen, sustainable energy production is increasingly being considered ...
“infiltration–evapotranspiration trade-off hypothesis”, which states that forest removal reduces the infiltration capacity of soil and the water losses through quick flow are larger than the gains from reduced evapotranspiration57. The deforestation impairs the maintenance of base flow, which changes ...
Understanding the hydrological effects of the Three Gorges Dam operation in the entire reservoir area is significant to achieving optimal dam regulation. In this paper, a large-scale coupled hydrological-hydrodynamic-dam operation model is
We estimated streamwater CO2concentration from a linear regression model (R2 = 0.39,P < 0.001) based on observations from 323 streams from the world’s major mountain ranges (Methods; Supplementary Fig.2). The streams included in the model drain catchments covering a broad range of ...
solutes to the channel system provided a basis for distinguishing four morphodynamic zones (divide, plateau, escarpment and valley) in the Kluda catchment... Małgorzata,Mazurek - 《Earth Surface Processes & Landforms》 被引量: 32发表: 1999年 Tectonic and climatic forcing on the Panj river syst...
