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...
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...
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...
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...
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...
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...
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...
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 ...
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...
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 ...
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...
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 ...
In order to examine the influence of the degree of convergence for converging geometry on lag time, a comparison of surface water lag times for converging and plane surfaces is made using the Overto...
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...
