Reservoirs and Dam Reservoirs Planning topics include: Reservoirs, reservoir site capacity and area elevation curves, reservoir losses, reservoir capacity determination using hydrograph and mass-curve.
Reservoir planning is a process that involves considering a reservoir project from its initial purpose statement to the final decision on a course of action. The planning process includes: Site selection: Factors like storage area and accessibility are considered. Investigations: Engineering surveys, geological and hydrological studies are conducted to determine reservoir capacity and ensure the foundation is stable. Assessment of current and future water use and availability: Reservoirs and dams for hydropower and other purposes affect the amount, timing, and quality of water available to other users in a river basin.
Dams and storage reservoirs for hydropower and other purposes affect the amount, timing and quality of the water available to other users in a river basin. Therefore the planning of new reservoirs requires the assessment of current and future water use and availability at the river basin scale. Dams and reservoirs can also improve flood protection.
However, dams can have a number of impacts on fish and fisheries, including: Contaminated fish: Reservoirs can trap pesticides and industrial chemicals, which can contaminate fish. Changes in fish biodiversity: Dams can cause changes in fish biodiversity, including a decline in the number of fish species.
