The effects of check dams on the amount and pattern of flood
In this study, field measurement, spatial information, and HEC-RAS modeling were used to determine changes in the amount and pattern of flow in a waterway due to the construction of check dams. The research was conducted in Khorkhoreh watershed, Kurdistan province, Iran. The location map of the structures and their upstream area was prepared in the GIS environment. The flow rate with different return periods was calculated from empirical methods. To simulate the changes in the flow pattern, the HEC-RAS model was calibrated. Flows and corresponding water levels were measured. The flow pattern and time was quantitatively calculated and compared with the conditions before construction. The results by HEC-RAS showed that in most structures, the flow velocity increased after passing the structures. In a 2-yr flood, the flow time increased by 82.8 minutes due to the check dams. This time is lower in floods with higher return periods.
