Groundwater Flow Model and Particle Track Analysis for Selecting Water Quality Monitoring Well Sites,and Soil Sampling Profiles
Mechanic villages heavy metals modelling pollution studies Imo River basin
2015/8/14
Researchers often use only surface drainage (imperical method) as a tradition to locate sites for installation of water quality monitoring wells, and soil sampling profile for pollution studies in urb...
Derivation of Instantaneous Unit Hydrograph for a sub-basin using Linear Geomorphological Model and Geographic Information Systems
Geographic Information System GIS Linear Geomorphological Model LGM GIUH
2015/8/14
Rainfall is converted into runoff and reaches the river and it becomes river flow. Geomorphological Instantaneous Unit Hydrograph (GIUH) based approach, which uses the geomorphologic parameters, is us...
Estimating land-use change impacts on direct runoff and non-point source pollutant loads in the Richland Creek basin (Illinois,USA) by applying the L-THIA model
land-use change runoff non-point source pollution hydrological model
2015/8/13
An export coefficient approach to hydrological and non-point source (NPS) pollution modeling enables quick and simple assessment of long-term impacts for planning purposes. An export coefficient and g...
A Spatially Distributed Event-Based Model to Predict Sediment Yield
Runoff sediment yield Geographic Information System GIS remote sensing watershed event-based
2015/8/11
A study has been conducted in three sub-watersheds to model the spatial distribution of runoff and sediment yield. The basic structure of the model includes generation of runoff using SCS curve number...
Erosion Risk Assessment using an Empirical Model of Pacific South West Inter Agency Committee Method for Zargeh Watershed, Iran
MPSIAC Erosion Sediment Yield Iran
2015/8/11
Watershed degradation due to soil erosion and sedimentation is one of the major environmental problems in Iran. In addressing the issue, a study on the validity of an empirical model of Pacific South ...
Support Soil Conservation Practices by Identifying Critical Erosion Areas within an American Watershed Using the GIS-AGNPS Model
AGNPS C factor erosion GIS Iowa T value water quality modeling
2015/8/11
Eroded soil from overland is one of the major nonpoint pollution sources in many watersheds. The subsequent sediment not only reduces conveyance capacity of streams and usable storage volume of reserv...

Frozen soil parameterization in a distributed biosphere hydrological model
Frozen soil parameterization distributed biosphere hydrological model
2010/4/7
In this study, a frozen soil parameterization has been modified and incorporated into a distributed biosphere hydrological model (WEB-DHM). The WEB-DHM with the frozen scheme was then rigorously evalu...
Selection of an appropriately simple storm runoff model
Selection appropriately simple storm runoff model
2010/4/7
An appropriately simple event runoff model for catchment hydrological studies was derived. The model was selected from several variants as having the optimum balance between simplicity and the ability...

2010/2/20
In this work we assess the uncertainty in modelling the groundwater flow for the Pampa del Tamarugal Aquifer (PTA) – North Chile using a novel and fully integrated multi-model approach aimed at explic...
Multi-model comparison of a major flood in the groundwater-fed basin of the Somme River (France)
Multi-model comparison major flood groundwater-fed basin Somme River
2010/2/1
The Somme River Basin is located above a chalk aquifer and the discharge of the somme River is highly influenced by groundwater inflow (90% of river discharge is baseflow). In 2001, the Somme River Ba...
