Many heuristic algorithms for solving optimization problems have been proposed, and efforts have been made to improve their efficiency in finding optimal solutions. However, the sampling-based search strategies of the heuristic optimization algorithms still require considerable time to locate optima...

Hydrologic Simulation Program - Fortran (HSPF) model calibration is typically done manually due to the lack of an automated calibration tool as well as the difficulty of balancing objective functions to be considered. This paper discusses the development and demonstration of an automated calibration...

The Soil and Water Assessment Tool (SWAT) uses hydrologic response units (HRUs) as the basic unit of all
model calculations. ArcSWAT, the ArcGIS interface for SWAT, allows users to specify thresholds of land cover, soil, and
slope in defining HRUs to improve the computational efficiency of simulatio...

The Shuttle Radar Topography Mission (SRTM) digital elevation model (DEM) has been a valuable resource for hydrological analysis, providing elevation data at a consistent resolution on a near-global scale. However, its resolution (3 arc-second or 90 m) is sometimes too low to obtain the desired leve...
