Research Abstract |
Annual mean sediment runoff volume is estimated from check dam survey data in a lot of mountainous small catchments. Moreover, sediment runoff potential power is defined as annual mean potential power which means annual mean energy precipitation including snow, and it is compared with annual mean sediment runoff volume. As the result, the relationship between the sediment runoff and the potential power is almost same as a practical formula of huge river basin, and has more sensitive response.
