A comparison of ASCAT and modelled soil moisture over South Africa，using TOPKAPI in land surface mode
ASCAT modelled soil moisture South Africa TOPKAPI land surface mode
2010/4/6
In this paper we compare two independent soil moisture estimates over South Africa. The first estimate is a Soil Saturation Index (SSI) provided by automated real-time computations of the TOPKAPI hydr...
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
2010/1/18
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...
Comparison of quadratic and non-linear programming (QP and NLP) optimization models in groundwater management
quadratic and non-linear programming optimization models groundwater management
2009/12/4
This project is concerned with the comparison of two algorithms used in groundwater management models, based on Quadratic Programming (QP) and Non-linear Programming (NLP) models.A quadratic objective...
Comparison of gliding box and box-counting methods in river network analysis
gliding box box-counting methods river network analysis
2009/11/3
We use multifractal analysis to estimate the Rényi dimensions of river basins by two different partition methods. These methods differ in the way that the Euclidian plane support of the measure is cov...
Particle dispersion processes in two-dimensional turbulence:a comparison with 2-D kinematic simulation
Particle dispersion processes two-dimensional turbulence 2-D kinematic simulation
2009/11/2
We study numerically the comparison between Lagrangian experiments on turbulent particle dispersion in 2-D turbulent flows performed, on the one hand, on the basis of direct numerical simulations (DNS...

COMPARISON DIMENSIONLESS UNIT HYDROGRAPHS THAILAND TAIWAN
2009/10/29
The characteristics of dimensionlcss unit hydrographs were derived from
floods from watersheds smaller than 1000 square kilometers locatcd in
Thailand. The dimensionless unit hydrographs were expres...
COMPARISON OF MEAN RAIN CATCH OF VARIOUS GAUGE NETWORKS
COMPARISON MEAN RAIN CATCH VARIOUS GAUGE NETWORKS
2009/10/29
After the substitution of stereo for horizontal orifices of rain gauges on
open steep slopes, the mean network catch in a subbasin with prevailing
windward exposure was increased by 11 O/o. In a sub...
COMPARISON OF THE METHODS OF ESTIMATING MEAN AREAL RAINFALL
COMPARISON METHODS OF ESTIMATING MEAN AREAL RAINFALL
2009/10/29
A comparison of nine different methods of estimating mean areal rainfall
is made. Five areas from three continents of the world are selected for application
of the methods. The methods are utilized ...
A Comparison of Some Methods for Estimation of Potential Evaporation
Methods Estimation Potential Evaporation
2009/10/28
In most of the important agricultural regions of the world, evaporation in the
growing season exceeds the precipitation, and also often the sum of
precipitation and plant available water in the root...
Five different rainfall - runoff models including three sophisticated conceptual
models (Sacramento, Stanford and Monash Models), a simple conceptual
model (Boughton Model) and a black-box or purely...
