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... Show more
