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
2010/4/7
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
2010/2/1
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...
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...
Comparison of Areal Snow Storage Sampling Procedures for Rangeland Watersheds
Areal Snow Storage Procedures Rangeland Watersheds
2009/10/28
The accuracy of photogrammetry in determining snow depth in mountainous
rangeland watersheds was evaluated on a 0.41-km2 subbasin of the Reynolds
Creek Experimental Watershed, located in the Owyhee ...
Finite Element Analysis of Square Aquifers Containing Pumped Wells and Comparison with Finite Difference Method
Finite Element Analysis Square Aquifers Pumped Wells
2009/10/28
The numerical solution of the behaviour of discrete time steps in digital computer
analysis of square aquifers containing pumped wells is examined by
using the finite element method with a 4 node li...
A Comparison of Some Methods of Deriving the Instantaneous Unit Hydrograph
Comparison Some Methods Instantaneous Unit Hydrograph
2009/10/28
The geomorphological instantaneous unit hydrograph (IUH) proposed by
Gupta et al. (1980) was compared with the IUH derived by commonly used
time-area and Nash methods. This comparison was performed ...
Estimating Regional Precipitation Trends Comparison of two Methods
Regional Precipitation Trends Comparison two Methods
2009/10/23
Two different methods werc applied to estimate long-term precipitation trends
representativ'e for regions in Norway. A new method, comparative trend analysis
(CTA), was applied on 142 homogeneous pr...
Comparison of Simulated Water Balance for Willow,Spruce,Grass Ley and Barley
Simulated Water Balance Willow Spruce Grass Ley Barley
2009/10/23
Evaporation from four cropping systems, i.e. willow, spruce, grass ley and barley,
was compared in this simulation study. The physically based soil model had
prev~ously been used to simulate a wide ...
