ON THE BULGARIAN SKAT RIVER WATERSHED RESERVOIRS CAPABILITY FOR FLOODING RESPONSE
Abstract
Flood occurrences outline the Bulgarian Skat river catchment as especially floods risk vulnerable territory. The floods observed there cause serious damages. This indicates that additional preventive and mitigation measures are needed. Part of the measures proposed in the connected to the area Flood Risk Management Plan (FRMP) 2022-2027 envisage changes in the rules for the operation of existing dams. In help of this activity in this material are presented the results of a study aiming determination of the potential opportunities for flood water retention using the existing in the watershed reservoirs. There are 34 reservoirs. Most of them were project and built for irrigation purposes only in the XX century, when the whole watershed was planned for agricultural activities. But as a result of the changed land use nowadays part of lands and irrigation reservoirs capacity volume remains unused. By this moment this possibility has not been envisaged as a mitigation activity. Thus the material can help the decision makers for the further refining of the management practice in the area. The research was carried out according to the author`s methodology, examining three working schemes, with 30%, 50% and 70% of the reservoirs volume. The obtained results specify the potential retention capacity for this specifically indicated cases and can help in further decisionmaking processes and cost-benefit analysis regarding the need of additional measures implementation.
