Última Calibration and Validation of SWAT for the Upper Maquoketa River Watershed AgEcon Kanwar, Ramesh S.; Reungsang, Pipat; Jha, Manoj K.; Gassman, Philip W.; Ahmad, Khalil; Saleh, Ali. A validation study has been performed using the Soil and Water Assessment Tool (SWAT) model with data collected for the Upper Maquoketa River Watershed (UMRW), which drains over 16,000 ha in northeast Iowa. This validation assessment builds on a previous study with nested modeling for the UMRW that required both the Agricultural Policy EXtender (APEX) model and SWAT. In the nested modeling approach, edge-of-field flows and pollutant load estimates were generated for manure application fields with APEX and were then subsequently routed to the watershed outlet in SWAT, along with flows and pollutant loadings estimated for the rest of the watershed routed to the watershed outlet. In the current study, the entire UMRW cropland area was simulated in SWAT, which...

Ano: 2005 URL: http://purl.umn.edu/18440 Cost Effectiveness of Rainwater Harvesting for Groundwater Recharge in Micro-Watersheds of Kolar District of India: The Case Study of Thotli Micro-Watershed AgEcon Nagaraj, N.; Pradhani, Umesh; Chengappa, P.G.; Basavaraj, G.; Kanwar, Ramesh S.. This study has estimated the supply augmentation of groundwater recharge due to creation of water harvesting structures and has assessed the cost-effectiveness of rainwater harvesting for groundwater recharge on watershed basis in one of the sub-watersheds of the Kolar district, Peninsular India — a typically hard-rock area. The study is based on the primary data for the year 2008-09 collected from a sample of 90 farmers having irrigation bore-wells in the selected watershed named Thotli. The study has indicated that the annual draft of irrigation water exceeds the annual recharge, causing a negative balance. On an average, the returns per rupee investment have been found to be ` 1.80 on farm pond, ` 1.78 on recharge pit and ` 1.39 on field bund. The cost...
