Uncertainties of SWAT Model in Irrigated Paddy Field Watershed

Abstract: Soil and Water Assessment Tool (SWAT)  merupakan model hidrologi yang sangat berpotensi digunakan untuk memodelkan daerah aliran sungai yang didominasi lahan pertanian. Namun demikian, struktur model ini dapat menyebabkan ketidakpastian khususnya apabila diaplikasikan untuk lahan sawah beririgasi. Hal ini dikarenakan SWAT pada awalnya dikembangkan untuk memodelkan lahan pertanian yang tidak memiliki genangan sehingga asumsi ataupun struktur modelnya berbeda dibandingkan dengan konsep pemodelan yang biasa digun… Show more

“…Studies conducted in Kashima river watershed in Chiba prefecture had an average of 0.66 for R² and 0.55 for NS based on different analysis conducted. The average of Pand R-factor was 0.93 and 0.79 respectively(Sofiyuddin et al, 2016). Similar range have also been obtained in watershed outside Japan.…”

“…Therefore, an advantage of Sakaguchi's model compared to PCPF-1@SWAT, which requires users to define two parameters to represent water loss from impoundment through paddy soil, is lesser number of fitting parameters for paddy simulation. Sofiyuddin et al [34] analyzed the performance and structure of Sakaguchi's model by comparing it to the original SWAT model, and concluded that the proposed model structure improved the model performance. Though those models showed acceptable simulation results in their research, the structures of those models are still based on the concept of pothole module.…”
