Comprehensive environmental models such as the Soil and Water Assessment Tool (SWAT) are becoming an integral part of decision making processes for effective planning and management of natural resources. Before their use as decision making aid, however, models must be properly evaluated to improve their prediction accuracy and reduce the likelihood of making decisions that could lead to undesir...

There has been a steady shift towards modeling and model-based approaches as primary methods of assessing watershed response to hydrologic inputs and land management, and of quantifying watershed-wide best management practice (BMP) effectiveness. Watershed models often require some degree of calibration and validation to achieve adequate watershed and therefore BMP representation. This is, howe...

Abstract This study aims to assess the climate change impacts on hydrological components in Ponnaiyar river basin using Soil Water Assessment Tool (SWAT) model. used 13 Global Climate Models (GCM) from Coupled Model Inter-comparison Project Phase 6 (CMIP6). Based performance evaluation of CMIP6-GCMs, best GCMs selected for future projections were EC-Earth3, MPI-ESM1-2-LR and MPI-ESM1-2-HR. SWAT...

This paper evaluates a recently created Soil and Water Assessment Tool (SWAT) calibration tool built using the Windows Azure Cloud environment and a parallel version of the Dynamically Dimensioned Search (DDS) calibration method modified to run in Azure. The calibration tool was tested for six model scenarios constructed for three watersheds of increasing size each for a 2 year and 10 year simu...

With the development of large-scale hydrologic modeling, computational efficiency is becoming more and more important. Rapid modeling and analysis are needed to deal with emergency environmental disasters. The Soil and Water Assessment Tool (SWAT) is a popular hydrologic model, which is less applied in large-scale watershed simulation because of its sequential characteristics. For improving the...

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...

Aggressive scaling of CMOS transistors has enabled extensive system integration and building faster and more efficient systems. On the flip side, this has resulted in an increasing number of devices that fail in shipped components in-the-field for a variety of reasons including soft errors, wear-out failures, and infant mortality. The pervasiveness of the problem across a broad market demands l...

in many flood control projects, watershed management and water resources development, calculation of the river flow discharge is of the paramount importance which requires a comprehensive hydrological modeling of the region of interest. in this respect, lack of the existence of hydrometric and meteorology measuring stations in most of watersheds, has caused numerous problems in development and ...
