Dams and reservoirs provide a great service to society. Their number continues to increase because of growing demands for water and energy. However, they disturb river flow and morphological processes and thus produce impacts on river system and ecology. Besides, the reservoirs themselves suffer from loss of storage and contamination due to sedimentation. The reduction of storage capacity poses challenges to dam authorities. The requirements for minimizing storage loss (i.e. sediment management) as well as impacts on the downstream ecosystem lead towards the approach of optimum reservoir operational rules. Sediment management practices, such as sluicing and flushing, may generate undesired morphological changes in the reach downstream of the dam. The gate operation rule and pattern are expected to influence this.
Deltares developed a modelling approach to simulate reservoir gate operation of the dam to understand the effect of different gate opening patterns on the morphological processes at upstream (the reservoir) and downstream river reach. Such modelling capability gives the possibility to generate the gate operation if the reservoir water level is given. The aim here is to seek improvements of the flushing process and to understand how this process affects the morphological changes downstream of the dam.
This 1-hour hands-on workshop, a break-out session of the Delft3D User Days offers the unique opportunity to simulate reservoir sedimentation processes using the new Delft3D FM Suite 2019.
You will gain experience using the combination of the D-Flow FM, D-Morphology and D-Real Time Control modules of the Delft3D FM Suite 2019.
