Hydrological Modeling in Agricultural Intensive Watershed: The Case of Upper East Fork White River, USA

Identifying the core hydrological processes of catchments is a critical step for operative modeling. This study attempts to assess long-term alterations in streamflow three adjacent Upper East Fork White River, Indiana USA, by employing SWAT model. The model simulations are spanning from 1980 up 2015 and distributed configurations periods identify monthly streamflow. For this purpose, water abstraction, land use, tillage, agricultural field drainage practices have been incorporated provide accurate data input. setup also integrates spatially disaggregated sectorial use surface groundwater resources integrating significant increases abstractions mainly public supply purposes. cover area governed rotating crops, while tile crucial parameters affecting regional balance. Streamflow prediction based on SUFI-2 algorithm SWAT-CUP interface has used calibration validation phases evaluation indicate progressively sufficient all configuration with NSE (0.87, 0.88, 0.88) PBIAS (14%, −7%, −2.8%) values at Seymour outlet. Surface runoff/precipitation as well percolation/precipitation ratios indicators trends wetter conditions. Model outputs upstream areas, successful predictions assessment studies test future implications climate change.
