Abstract [en]

During high floods the erosion along the shoreline will increase, which can lead to floating debris ending up in the river and the spillways will be clogged. There are a variety of preventive measures that can be taken to reduce the risk of floating debris. It can be anything from removing trees in sensitive areas, to set up booms that control the debris. To find out how much potential debris there are, an inventory has been made for the Granfors and Krångfors reservoirs. Since no similar work has been made, different methods had to be worked out for the different parts of the project. • Method of Inventory • Method of Calculating the amount of debris • Method for Risk Analysis To better understand how to apply the appropriate preventive measures, a short-term study of how debris behaves at high flows, and how different types of booms and protective visors work have been made. The results of the inventory and risk analysis showed that there is a possibility for a relatively large amount of debris for both facilities implying to a probability that the facilities will not be able to cope with the amount of debris without any preventive action is taken. The recommendation for both reservoirs is a cleanup of the debris and deployment of diversion booms. The booms should be placed either in front of the hydroelectric plants and divert the debris onto land, or deflect the debris by the spillway in Granfors, and then be taken care of, either in Krångfors or deflected by Krångfors, and taken care of in Selsforsen.
