SWAT developments and recommendations for modelling agricultural pesticide mitigation measures in river basins Vrije Universiteit Brussel
Pesticides are useful for agriculture because of their ability to protect crops against pests. At the same time, excessive loading of pesticides in water bodies can produce toxic conditions that harm sensitive aquatic species, and render the water unfit for human consumption. Therefore, measures need to be designed, evaluated and undertaken in order to reduce pesticide pollution. In this study we focus on the Nil catchment, a small basin ...
Critical review of SWAT applications in the upper Nile basin countries Vrije Universiteit Brussel
Linking SWAT and sobek using open modeling interface (openmi) for sediment transport simulation in the blue nile river BASIN Vrije Universiteit Brussel
Computer models assist basin-scale decision making by taking into account upstream-downstream interdependencies. The SWAT (hydrological) model code was developed into an OpenMI-compliant version and linked with the SOBEK (hydrodynamic) model to extend SWAT's simulations of basin-scale streamflow and sediment transport. The development of an OpenMI-compliant version of SWAT involved reorganizing the SWAT model code and wrapping it with the ...
Effects of climate, objective function and sample size on global sensitivity in a SWAT Model Vrije Universiteit Brussel
Environmental models typically possess large uncertainty due to contributions from model structure, assumptions, parameterization, and data errors, not to mention lack of consideration of problem framing and the associated choice and justification of objective function. Sensitivity analysis (SA) is a fundamental tools to help identify uncertainties relevant to the modelling objectives. It provides information on the impact on model outputs ...
SWAT Vrije Universiteit Brussel
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. In addition, SWAT-CUP was recently developed and ...
The effects of land use change on hydrological responses in the Choke Mountain Range (Ethiopia) - A new approach addressing land use dynamics in the model SWAT Vrije Universiteit Brussel
Land use change (LUC) is a very important issue considering global dynamics and their responses to environmental and socio-economic drivers. Especially in fast changing developing countries, it is a scientific challenge to predict land use changes and their effects on water availability, flood risk and erosion rates. To address these issues, catchment models must be able to deal with land use dynamics. Unfortunately, many models handle land ...
Evaluation of streamflow simulation by SWAT model for two small watersheds under snowmelt and rainfall Vrije Universiteit Brussel
The degradation of the river water quality in Canadian rural catchments is of concern. In these catchments, the Soil Water Assessment Tool (SWAT) model can help better understand the problems related to diffuse pollution. The numerous documented applications of SWAT have been dominated by areas uniquely driven by rainfall. Given that Canadian hydroclimatic conditions differ due to the presence of a seasonal snowpack of long duration, ...
The use of satellite images for evaluating a SWAT model Vrije Universiteit Brussel
Remote sensing has become an indispensable source of input data and parameters estimation for environmental modelling. In the presented study evapotranspiration (ET) and leaf area index (LAI) were derived from satellite images and used for the evaluation of a hydrological model. Such applications can help to identify simulation inaccuracies and optimize the performance in areas with limited data availability. Moreover daily observations can ...
Calibration of spatially distributed hydrological processes and model parameters in SWAT using remote sensing data and an auto-calibration procedure Vrije Universiteit Brussel KU Leuven
In this paper, evapotranspiration (ET) and leaf area index (LAI) were used to calibrate the SWAT model, whereas remotely sensed precipitation and other climatic parameters were used as forcing data for the 6300 km2 Day Basin, a tributary of the Red River in Vietnam. The efficacy of the Sequential Uncertainty Fitting (SUFI-2) parameter sensitivity and optimization model was tested with area specific remote sensing input parameters for every ...
