GSSHA (Gridded Surface/Subsurface Hydrologic Analysis) [1] is a two-dimensional, physically based watershed model developed by the Engineer Research and Development Center of the United States Army Corps of Engineers. It simulates surface water and groundwater hydrology, erosion and sediment transport.
Vflo output is in the form of hydrographs at selected drainage network grids, as well as distributed runoff maps covering the watershed. Model applications include civil infrastructure operations and maintenance, stormwater prediction and emergency management, continuous and short-term surface water runoff, recharge estimation, soil moisture ...
The models were created with the software Surface-Modeling System (SMS) of Aquaveo LLC" (Gerstner, Belzner, and Thorenz, 976). [ 17 ] This article "describes the mathematical formulation, numerical implementation, and input specifications of rubble mound structures in the Coastal Modeling System (CMS) operated through the Surface-water Modeling ...
A time series can be applied to a polygon, or a series of polygons. Alternatively a rainfall grid can be applied. This is particularly useful for applying RADAR rainfall. ANUGA can model culverts and bridges with code from the open source Watershed Bounded Network Model (WBNM){Boyd, Rigby, VanDrie}, having a pipe, box and trapezoid routine.
Watershed delineation is the process of identifying the boundary of a watershed, also referred to as a catchment, drainage basin, or river basin. It is an important step in many areas of environmental science, engineering, and management, for example to study flooding, aquatic habitat, or water pollution.
GIS revolutionized curation, manipulation, and input for complex computational hydrologic models [2] [3] For surface water modeling, digital elevation model are often layered with hydrographic data in order to determine the boundaries of a watershed. [4] Understanding these boundaries is integral to understanding where precipitation runoff will ...
Its economy is slowing down systemically, its construction sector is weak, wind and solar energy are growing rapidly, and hydro-power output will rebound after a series of droughts.
The main conclusion of the study was that the HBV model can be used to predict material transport on the scale of the drainage basin during stationary conditions, but cannot be easily generalised to areas not specifically calibrated. In a different work, Castanedo et al. applied an evolutionary algorithm to automated watershed model calibration ...
