Determination of active zone of bed load sediment trap
Sodomka, Václav ; Pařílková, Jana (referee) ; Zachoval, Zbyněk (advisor)
The bachelor thesis deals with determination of the active zone of bed load sediment trap in the water reservoir of Nové Heřminovy. A ready-made physical model of the sediment space was used and more accurate measurements of behaviour of the proposed object were performed. Ultrasonic speed field measurement was used for determination of the active zone of the sediment space. The Surface-water Modeling System programme was applied for evaluation. This information can be used for further assessment of bed load sediment trap. The results show that transported bottom sediment is trapped in the space determined for this purpose and there are no unforeseen phenomena. The model behaves within the limits of the initial assumptions. That means it is correctly designed and it will be more likely to serve its purpose.

Sediment deposition in reservoir of Nové Heřminovy dam
Kammermayer, Jan ; Šedivý, Jiří (referee) ; Zachoval, Zbyněk (advisor)
The thesis deals with silting of water reservoir Nové Heřminovy. There's describe design of artificial traffic and evaluate its effectiveness. To determine the flow of sediment into the reservoir with use a partially calibrated one-dimensional numerical model of sediment transport with deformation of bed is made in software HEC-RAS. Silting reservoirs is assessment with two methods, the results are compared and describes their limitations. Reservoirs silting evaluates through volume changes in reservoir storage in time.
