SWAT (Soil and Water Assessment Tool) is a comprehensive, semi-distributed river basin model that requires a large number of input parameters, which complicates model parameterization and calibration. Several calibration techniques have been developed for SWAT, including manual calibration procedures and automated procedures using the shuffled complex evolution method and other common methods. ...

Reliable and accurate streamflow prediction plays a critical role in watershed water resources planning management. We developed new hybrid SWAT-WSVR model based on 12 hydrological sites the Illinois River (IRW), U.S., that integrated Soil Water Assessment Tool (SWAT) with Support Vector Regression (SVR) calibration method coupled discrete wavelet transforms (DWT) to better support modeling wat...

Using the probably approximately correct (PAC) learning hypothesis, we have conducted experiments using clustered computers, high-performance workstations and ad-hoc grids of personal computers, to develop an analytical model for, and demonstrate asymptotic convergence of simple parallel search in the parameter space of complex environmental models such as the Soil and Water Assessment Tool (SW...

Climate change-induced extreme precipitation causes coastal flooding. A streamflow simulation in watersheds, Wolf River Watershed (WRW) and Jourdan (JRW), was conducted using the Soil Water Assessment Tool (SWAT) to compare variation flow at different climates analyze flood frequency. Baseline models were auto-calibrated with SWAT calibration uncertainty programs (SWAT-CUP). Kling–Gupta efficie...

Original scientific paper Hydrological simulation in meteorological ungauged areas has always been a difficult problem for the study on atmospheric and hydrological coupling; meanwhile, it is also one of the important factors that restrict model development and basin water resource knowledge. To analyze the mechanism of atmospheric and hydrological coupling, this study quantitatively evaluated ...

مدیریت صحیح حوضه­های آبریز کشور به عنوان یکی از مهمترین روش­های استفاده بهینه از منابع آب مطرح می­شود. در این راستا عقیده بر این است که شبیه­سازی پدیده­های هیدرولوژیکی در حوضه­ها می­تواند راه­حل بهینه­ای باشد. در این تحقیق از مدلSWAT ، برای شبیه­سازی هیدرولوژیکی حوضه فیروزآباد واقع در استان فارس استفاده شد. در ابتدا رواناب حوضه طی سال­های آماری2010-1994 در مدل SWAT شبیه­سازی گردید. سپس نتایج با...

the adequacy of the swat model in the estimation of runoff, sediment yield and nitrate loss in the gorganrood watershed was tested, using the existing spatial database as the primary data. the model was then executed for a 31-years’ time period. in combination with the swat model, the sequential uncertainty fitting program (swat-cup and sufi-2) was added used to calibrate and validate a hydrolo...

در این پژوهش به منظور تخمین پارامترهای مدل SWAT و بکارگیری آن برای شبیه‌سازی هیدرولوژیکی حوضه آبریز مهابادچای (از رودخانه‌های منتهی به دریاچه ارومیه) و پیش‌بینی آبدهی رودخانه، از جذب داده استفاده می‌شود. در ابتدا پس از مدلسازی با استفاده از SWAT، روش SUFI2 که جزء روشهای واسنجی خودکار مبتنی بر عدم‌قطعیت و بهینه‌سازی بوده و درون بسته نرم‌افزاری SWAT-CUP در دسترس است، برای واسنجی مدل SWAT استفاده ...
