The Effect of Daily Rainfall Derived from TRMM Data on SWAT Model Performance in Runoff Simulation |
|
| چکیده انگلیسی مقاله |
Mountainous areas and watersheds in Iran are important sources in surface water supply and groundwater storage. Therefore, accurate simulation of hydrological processes in the watersheds is important. Several models have been developed to simulate hydrological processes. One of the most common and efficient models is Soil and Water Assessment Tool (SWAT) model. Daily rainfall is an important input into the SWAT model and hydrological models; however, usually these meteorological stations are not available or their distribution is not acceptable in several watersheds. To cope with this problem, daily rainfall were extracted from TRMM data in the Taleghan Dam watershed. The extracted daily rainfall data are then imported into the SWAT model and the model was calibrated and validated using SWAT-CUP for runoff simulation. The model was also calibrated and validated using daily rainfall obtained from meteorological stations similar to the statistical period used to run the model in pervious stage. Finally, their results were compared with each other. The results showed that the high spatial and temporal resolution of TRMM rainfall data compared to the daily rainfall obtained from meteorological stations increases the SWAT model performance in runoff simulation. |
