A distributed-framework hydrologic modeling system (DF-HMS) is a primary and significant component of basin (DFBMS), which simulates the hydrological processes responses after rainfall at scale, especially for non-homogenous basins. The DFBMS consists 11 feature units (HFUs) involving vertical horizontal geographic areas in basin. Appropriate or hydraulic methods are adopted different HFUs to s...

Deterministic rainfall-runoff models require parameter calibration with the aim of matching the modeled streamflow record to an observed record as closely as possible. Much attention has been focused on automated methods of model calibration using meta-heuristics, such as genetic algorithms. In this study, two meta-heuristic algorithms were compared: the shuffled complex evolution (SCE) algorit...

The purpose of this study is to understand flooding in a 1,725-km2 arid catchment Makkah Province, Saudi Arabia, with very limited ground observations. This mountainous includes densely urbanized areas built on lowlands and the ephemeral streams flood zones, which makes them vulnerable flooding. A physically based, fully distributed hydrologic model was produced by three Integrated Multi-satell...

Distributed, physics-based hydrologic models require spatially explicit specification of parameters related to climate, geology, land-cover, soil, and topography. Extracting these parameters from national geodatabases requires intensive data processing. Furthermore, mapping these parameters to model mesh elements necessitates development of data access tools that can handle both spatial and tem...

[1] There is increasing interest in the use of multiple measurement types, including indirect (geophysical) methods, to constrain hydrologic interpretations. To date, most examples integrating geophysical measurements in hydrology have followed a three‐step, uncoupled inverse approach. This approach begins with independent geophysical inversion to infer the spatial and/or temporal distribution ...

Control of the Panama Canal Basin transfers from the United States of America to the Republic of Panama on the last day of 1999. The Panamanian and United States governments are concerned that the rapid deforestation of the Panama Canal Basin will jeopardize the future operation of the Panama Canal, the capacity and quality of potable water supplied to Panama City, and the diverse rain forest e...
