Effect Of Irrigation On Stream Flow In Mountainous Small Watershed Of South Korea
This study examined change of stream flow with and without agricultural reservoirs which may include rice paddy fields. For this purpose a modified BROOK90 has been used to simulate stream flow under the some environmental change scenarios. Seven years (from 2000 to 2006) of historical weather data and daily discharge records has been considered. This research shows that management of land use is important as a measure to ensure environmental flows as well as proper operation of the reservoir.
