Auto-Calibration of Hydrological Models Using High Performance Computing

Hydrological models have been increasing in complexity over the years. These models rely on their calibration to simulate real world conditions as close as possible. Calibration is a tedious and time-consuming process. An auto-calibration algorithm (SCE-UA) developed by Duan et al. [1992], has been successfully used in hydrological modeling area. This is a serial algorithm and as complexity of ...

Grid based calibration of SWAT hydrological models

The calibration and execution of large hydrological models, such as SWAT (soil and water assessment tool), developed for large areas, high resolution, and huge input data, need not only quite a long execution time but also high computation resources. SWAT hydrological model supports studies and predictions of the impact of land management practices on water, sediment, and agricultural chemical ...

Simultaneous calibration of hydrological models in geographical space

Hydrological models are usually calibrated for selected catchments individually using specific performance criteria. This procedure assumes that the catchments show individual behavior. As a consequence, the transfer of model parameters to other ungauged catchments is problematic. In this paper, the possibility of transferring part of the model parameters was investigated. Three different conce...

Intelligent Manipulation and Calibration of Parameters for Hydrological Models

It would be greatly helpful to neophytes if knowledge-based system technology incorporating the existing heuristic knowledge about model manipulation can be integrated into the hydrological system. This paper delineates the development and implementation of a prototype knowledgebased system for model manipulation for hydrological processes by employing an expert system shell. The architecture a...

Calibration of global hydrological models based on streamflow characteristics

Streamflow (Q) estimation in ungauged catchments is perhaps the most fundamental challenge faced by hydrologists. A promising approach to calibrate hydrological models in ungauged catchments is to use estimated Q characteristics to identify acceptable model parameter sets. This study is the first to test this approach at the global scale using a large, heterogeneous catchment set. First, observ...
