This paper presents the decoupled hydrological discretization (DHD) scheme for solving the shallow water equations in hydrological applications involving surface runoff in rural and urban basins. The name of the scheme is motivated by the fact that the three equations which form the two-dimensional shallow water system are discretized independently from each other and thus, the numerical scheme...

Basin morphometry is a means of numerically analysing or mathematically quantifying different aspects of a drainage basin. In the present study, morphometric analysis of the Baitarani basin has been carried out using earth observation data and geographical information system (GIS) techniques. The morphometric parameters considered for analyses include the linear, areal and relief aspects of the...

A model of solute transport in overland flow is developed and applied to the simulation of surface fertigation. Water flow is simulated using the depth-averaged, one-dimensional shallow water equations. Solute flow is represented by an advectiondiffusion model. The resulting set of three partial differential equations is sequentially solved at each time step. First, water flow is computed using...

High resolution (infra-metric) topographic data, including photogrammetric born 3D classified data, are becoming commonly available at large range of spatial extend, such as municipality or industrial site scale. This category of dataset is promising for high resolution (HR) Digital Surface Model (DSM) generation, allowing inclusion of fine above-ground structures which might influence overland...

The open source 30 m Copernicus DEM (COP-DEM) has been used to derive the geo-morphometric and topo-hydrological characteristics of Betwa River Basin. Drainage network with 7th order stream mostly dendritic pattern delineated using Strahler’s method. drainage density, frequency, form factor, length overland flow circulatory ratio basin were computed as 0.38 Km/Km2, 0.08 Km−2, 0.23, 1.31, 0.20, ...

Due to the rapid population growth and urbanization in the City of Calgary, the Elbow River watershed in southern Alberta covering 1238 km has been subjected to considerable land-use changes over the last decade. The objective of this study is to assess the impact of land-use intensification simulated with a cellular automata (CA) model on the hydrological processes of the watershed using MIKE-...

Land-use change acts as a potential moderator of flood risk, affecting vegetation and soil properties thus influencing the storage flow water across landscapes. This study, conducted in northwest England, investigated physical their hydrological function using overland moisture sensors, for five upland grassland habitats each created through management action. Overland was common, occurring up ...

Abstract Soil wearing away or erosion is a chief agent of land loss in agricultural and regarded worldwide as serious environmental hazard. This study performed watershed prioritization using morphometric parameters based on fuzzy best worse method (F-BWM) GIS integration for Gusru Watershed, India. prioritizes sub-watersheds the area from viewpoint soil five major i.e., stream frequency ( F s ...
