Reservoir impacts on water security

Impacts of climate change on water resources and water environment in the Three Gorges Reservoir

Climate change is one of the major global issues commonly concerned by international communities. Taking the Three Gorges Reservoir which is the largest water conservancy project in China as the object, this study attempts to clarify the current conditions of water resources and water environment especially the spatial distribution characteristics of water resources amount and main non-point so...

Small Reservoir Impacts on Stream Water Quality in Agricultural, Developed, and Forested Watersheds: Georgia Piedmont, USA

Small reservoirs are prevalent landscape features and an important component of headwater hydrology. Tens of thousands of small ponds, most less than a hectare, were constructed over the past century within the United States. While remote-sensing and geographic-mapping technologies assist in quantifying these features, their influence on water quality is less well understood. This study reports...

Impacts of Forest to Urban Land Conversion and ENSO Phase on Water Quality of a Public Water Supply Reservoir

We used coupled watershed and reservoir models to evaluate the impacts of deforestation and l Niño Southern Oscillation (ENSO) phase on drinking water quality. Source water total organic carbon (TOC) is especially important due to the potential for production of carcinogenic disinfection byproducts (DBPs). The Environmental Fluid Dynamics Code (EFDC) reservoir model is used to evaluate the diff...

Climate impacts on food security and nutrition

Climate change impacts on crop yield, crop water productivity and food security – A review

This paper provides a comprehensive review of literature related to the assessment of climate change impacts on crop productivity using climate, water and crop yield models. The existing studies present that climate change models with higher spatial resolution can be a way forward for future climate projections. Meanwhile, stochastic projections of more than one climate model are necessary for ...
