Summary
A reservoir is a replacement of a segment of the river with a watercourse that is quite different, a larger, more quiescent water body with different water quality and capable of stratification. This chapter describes design and functions of river reservoirs. The main challenges faced by SERIDAS reservoirs are highlighted. Special attention is given to a reservoir’s dependable yield, which can be maintained constantly without failure throughout the time history of reservoir storage. All reservoirs act as sediment traps and will eventually silt up unless special actions are taken to manage sediment. Reservoirs significantly alter the hydrology of the river downstream from the dam and can affect its water quality and its ecosystem. With increases in population and agriculture, water demands will increase, exacerbated by climate changes. Skillful management will be needed to temper conflicts that arise over how reservoirs will be operated under situations of incompatible objectives.
