| 1 | Evaluation of SWAT sub-daily runoff estimation at small agricultural watershed in Korea显示文摘A study was undertaken for the prediction of runoff flow from 0.8 ha field-sized agricultural watershed in South Korea using Soil and Water Assessment Tool (SWAT) sub-daily. The SWAT model with sub-daily configuration predicted flow from the watershed within the range of acceptable accuracy. The SWAT sub-daily simulations were carried out for a total of 18 rainfall events, 9 each for calibration and validation. Overall trend and extent of matching simulated flow for the rainfall events in 2007-2008 with measured data during the calibration process were coefficient of determination (R2) value of 0.88 and Nash and Sutcliffe Efficiency (ENs) value of 0.88. For validation, R2 and ENs values were 0.9 and 0.84, respectively. Whereas R2 and ENs values for simulation results using daily rainfall data were 0.79 and -0.01, respectively, that were observed to be out of acceptable limits for the model simulation. The importance of higher time resolution (hourly) precipitation records for flow simulation were evaluated by comparing Ra and ENs with 15 min, 2 h, 6 h and 12 h precipitation data, which resulted in lower statistics with increases in time resolution of precipitation data. The SWAT sub-daily sensitivity analysis was performed with the consideration of hydraulic parameter and was found as in the rank order of CN2 (curve number), ESCO (soil evaporation compensation factor), GW_DELAY (ground water delay time), ALPHA BF (base flow alpha factor), GWQMN (a threshold-minimum depth of water in the shallow aquifer required for return flow to occur), REVAPMN (minimum depth of water in shallow aquifer for re-evaporation to occur), LAT TIME (lateral flow travel time) respectively. These sensit]-ve parameters were evaluated at 10% higher and lower values of the parameters, corresponding to 70.5% higher and 23.2% lower in simulated flow out from the SWAT model. From the results obtained in this study, hourly precipitation record for SWAT sub-daily with Green-Ampt infiltration method was proven to be efficient for runoff estimation at field sized watershed with higher accuracies that could be efficiently used to develop site- specific Best Management Practices (BMPs) considering rainfall intensity, rather than simply using daily rainfall data. | Ganga Ram Maharjan Youn Shik Park Nam Won Kim Dong Seok Shin Jae Wan Choi Geun Woo Hyun Ji-Hong Jeon Yong Sik Ok Kyoung Jae Lim | 2013 | Frontiers of Environmental Science & Engineering2013，7，1： | 2 |
