Effect of land use-based surface roughness on hydrologic model output
land use-based surface roughness hydrologic model coefficient Manning
2015/8/14
The Manning’s roughness coefficient (n) is commonly used to represent surface roughness in lumped and distributed hydrologic models. Model parameter sensitivity studies identify runoff response to be ...
Assessment of the Impact pf Mining on Agricultural Land using Erosion-Deposition Model and Space Borne Multispectral Data
Mining Agricultural Land Erosion-Deposition Model Space Borne Multispectral Data
2015/8/6
Since erosion of mine overburden and mine dump leads to its deposition down the slope in the catchment, an attempt was made to study the erosion-deposition pattern in a micro watershed in part of Goa ...
LINKAGE OF ARCVIEW GIS WITH THE RZWQM MODEL
geographic Information System quasi-distributed mathematical modeling
2015/8/6
The Root Zone Water Quality Model (RZWQM) is a one-dimensional, lumped field-scale model. It can simulate major physical, chemical, and biological processes in an agricultural crop production system. ...
Estimating sediment yield using Agricultural Non-Point Sources (AGNPS) model: The effects of slope information from different GIS softwares
Geographical Information System GIS slope information Sediment yield AGNPS model tropical catchment
2015/8/6
This study compares the effects of slope information derived from three GIS software on sediment yield as estimated using AGNPS model. The three GIS software are IDRISI for Windows, ERDAS Imagine and ...
Diffused Interface Model to Prevent Ingress of Sea Water in Multi-Layer Coastal Aquifers
Diffused Interface Model Ingress Sea Water
2015/8/6
In many regions coastal aquifers are major source of supply of water to various sectors. However, indiscriminate pumping from these aquifers leads to seawater intrusion which is difficult to contain. ...
A transferable bio-optical model for quantification of inland water caynobacterial pigments
Inherent optical properties chlorophyll-a phycocaynin inland waters
2015/1/16
Cyanobacterial blooms are currently one of the most important issues faced by environmental agencies, water authorities and public health organizations. Remote sensing provides an advanced approach to...
Generalized versus non-generalized neural network model for multi-lead inflow forecasting at Aswan High Dam
non-generalized neural network model multi-lead inflow
2011/3/15
Artificial neural networks (ANN) have been found efficient, particularly in problems where characteristics of the processes are stochastic and difficult to describe using explicit mathematical models....
An assessment of future extreme precipitation in western Norway using a linear model
extreme precipitation western Norway linear model
2010/12/22
A Linear Model (Smith and Barstad, 2004) was used to dynamically downscale Orographic Precipitation over western Norway from twelve General Circulation Model simulations. The GCM simulations come from...
Genetic programming as a model induction engine
Genetic programming model induction engine
2009/12/7
Present day instrumentation networks already provide immense quantities of data, very little of which provides any insights into the basic physical processes that are occurring in the measured medium....
A virtual GIS-based hydrodynamic model system for Tamshui River
virtual GIS-based hydrodynamic model system Tamshui River
2009/12/4
A computer infrastructure which integrates the geographic information system (GIS), hydrodynamic model, visualization and network applications was developed and applied in Tamshui River, Taiwan. A dig...
Fuzzy rule-based model for contaminant transport in a natural river channel
Fuzzy rule-based model contaminant transport natural river channel
2009/12/4
Fuzzy rules are used to model solute dispersion in a river dead zone, such that the turbulent diffusion is determined by a fuzzy inference system which relates the local mean velocity shear to the lon...
Fuzzy rules based model for solute dispersion in an open channel dead zone
Fuzzy rules based model solute dispersion open channel dead zone
2009/12/4
A method has been developed to estimate turbulent dispersion based on fuzzy rules that use local transverse velocity shears to predict turbulent velocity fluctuations. Turbulence measurements of flow ...
