The technical and institutional performance evaluation of Geray Irrigation Scheme was made in order to identify management practices for implementation to improve the system operation and the performa...
Soil moisture active and passive microwave products:intercomparison and evaluation over a Sahelian site
Soil moisture active passive microwave products intercomparison evaluation Sahelian site
2010/2/1
This paper presents a comparison and an evaluation of five soil moisture products based on satellite-based passive and active microwave measurements. Products are evaluated for 2005–2006 against groun...
Evaluation of an ASM1 model calibration procedure on a municipal–industrial wastewater treatment plant
ASM1 model calibration procedure municipal–industrial wastewater treatment plant
2009/12/4
The purpose of the calibrated model determines how to approach a model calibration, e.g. which information is needed and to which level of detail the model should be calibrated. A systematic model cal...

2009/12/4
The comprehensive and systematic management of watersheds is essential for reducing the adverse environmental impacts arising from anthropogenically caused erosion and subsequent sedimentation. This p...
EVAPRO:economic and financial evaluation of water supply projects
economic and financial evaluation water supply projects
2009/12/4
The present paper describes a computer-based system for water supply project appraisal called EVAPRO, standing for EVAluation of water PROjects. The aim of EVAPRO is to facilitate economic and financi...
Fuzzy set based error measure for hydrologic model evaluation

Evaluation of a Precipitation Map Using a Smoothed Elevation-Precipitation Relationship and Optimal Estimates(Kriging)
Precipitation Map Smoothed Elevation-Precipitation Relationship Optimal Estimates
2009/10/28
Using 45 rain gauges, located in the center of French-speaking Switzerland
(approx. 1,600 sq. km), we evaluate an annual mean precipitation map for the
years 1974, 1975 and 1976. This estimate is ba...
An Evaluation of the Importance of Transmissivity,Head and Concentration Data for Contaminant Transport Modelling
Importance of Transmissivity Concentration Data Contaminant Transport Modelling
2009/10/27
The 3 basic data types of contaminant hydrology are examined by stochastic
modelling of a groundwater contamination case. The stochastic transport model,
which is of the Monte Carlo type, uses a num...
