The primary use of all reservoiris to provide a means ofregulating downstream surfacewater flows over time andspace. Other purposes may include storage volume management for recreation and flood control, and storage and release management for hydropower production.
Reservoir storage capacity can be divided among three major uses: Used for downstream flow Active regulation and for water supply, storage recreational development or hydropower production Dead storage Required for sediment collection Capacity reserved to reduce Flood storage potential downstream flood damage during flood events
Important elements of the water resources system. They provide regulating functions with respect to both quantity (eg. flood attenuation) and quality (self purification). Most wetlands support valuable ecological systems.Most wetlands support valuable ecological systems.
• River basin models focusing on water quantities are mostly used to investigate whether sufficient water is available to satisfy the various use functions and to identify measures to match supply and demand.• The core of most river basin models consists of keeping track of the water balance of the whole river basin.• The analysis of water quality and ecology is done using another model of for a specific part of the system e.g. river stretch, reservoir or ground water system. This model will be described in Chapter 12.
