abstract regarding temporal variation of rivers discharge and demands, for suitable use of dam reservoirs stored water, application of operation rule curves is necessary. operation rules are expressed with rule curves. application of yield model is one of the methods of operation curve preparation, which correlates reservoir operation with reservoir storage volume in first period. in this study...

In most cases of reservoir-induced seismicity, seismicity follows the impoundment, large lake-level changes, or filling at a later time above the highest water level achieved until then. We classify this as initial seismicity. This ‘‘initial seismicity’’ is ascribable to the coupled poroelastic response of the reservoir to initial filling or water level changes. It is characterized by an increa...

As a follow up to the 2007 drought and water scarcity in Georgia and especially in North Georgia, there is a greater need of creating new water reservoirs. The main goal of this study is to use geospatial technology, engineering and environmental knowhow to find suitable locations in North GA for building a reservoir to serve primarily for drinking water supply and irrigation. Another objective...

~BSTRACT: A~ unsteady ~wo-dimens~onal (20) reservoir hydrodynamics and transport model is employed to slm~late contammate~ denSity cu~ents m the Shasta Reservoir after a chemical spill into the Sacramento River, Cahf. Three flow regimes (plungmg flow, underflow, and interflow) and their occurrence are captured by the laterally ~verag~d model. Transp~~ and mixing processes in the temperature-str...

Climate change and increased urban demand can significantly stress water supply systems, emphasizing the importance of reallocating reservoir storage for the designed uses. Most studies on climate change assessment have analyzed arid region reservoirs due to high interannual variability in streamflows. This study focuses on a within-year reservoir system, Lake Jordan in North Carolina, from a t...

Hydroelectric Pumped Storage (PHS) is the most widely utilised form of large-scale electrical energy storage (EES). The energy is stored as the potential energy of water raised against gravity. Water is pumped from a lower reservoir (1) to a higher reservoir (2), using the energy provided by the pumping unit (3), storing it as potential energy in the water. Figure 1 is a simple scheme of a PHS ...

background : collection and storage of roof rain water have been practiced for long time ago in iran and many other countries. water of cisterns is usually used as potable water. in golestan province many of rural torkman residents reservoir the most part of their potable water from roof rain in cisterns. in this province there are over 2600 cisterns. methods : to study the water quality, micro...

The impact of the construction of a large dam on riparian vegetation cover can be multifold. How the riparian vegetation cover changes at different elevation zones in response to the construction of a large dam and the subsequent impound of reservoir water is still an open question. In this study, we used satellite remote sensing data integrated with geographic information system (GIS) to monit...
