Spatial Variability and Prediction Modeling of Groundwater Arsenic Distributions in the Shallowest Alluvial Aquifers in Bangladesh
Arsenic Bangladesh distribution spatial variability semivariogram prediction models
2015/8/13
Elevated arsenic in groundwater is the greatest environmental problem in Bangladesh. Spatial variability of arsenic in groundwater has been examined by semivariogram analysis that revealed high degree...
Spatial variability of water repellency in pine forest soil
spatial variability water repellency WDPT test infiltration sorptivity
2015/2/3
The variability of water repellency of pine-forest arenic regosols and its influence on infiltration processes were measured in southwest Slovakia. The water drop penetration time (WDPT) tests of soil...
Calibration analysis for water storage variability of the global hydrological model WGHM
Calibration analysis water storage variability global hydrological model WGHM
2010/2/1
The aim of this study is to provide an improved global simulation of continental water storage variations by calibrating the WaterGAP Global Hydrology Model (WGHM) for 28 of the largest river basins w...
Chaos in rainfall:variability,temporal scale and zeros
Chaos in rainfall variability temporal scale zeros
2009/12/4
A recent study on rainfall observed at the Leaf River basin reports that the presence of a large number of zeros in the data significantly underestimates the correlation dimension. The present study a...

VARIABILITY SEASONAL AND ANNUAL RUNOFF NORWAY
2009/10/29
A preliminary map of variability of annual runoff in Norway has been
prepared based on estimates of the coefficient of variation cv for 56
non-regulated discharge stations having more than 35 years ...
On the Values and Variability of Degree-Day Melting Factor in Finland
Values Variability Degree-Day Melting Factor Finland
2009/10/28
About 96,000 snow depth and 17,000 snow density measurements were used
to study the most widely used variable in snowmelt forecasting, the degreeday
factor. This data was collected on 12 stake stati...
Assessment of True Variability of Small Rainfall Events in a Small Mountainous Watershed in the Summer
Assessment True Variability Small Rainfall Events Mountainous Watershed
2009/10/28
The standard error of mean areal rainfall was calculated for various densities
of rain gauge network in a small mountainous watershed in the summer of
1978. It is shown that a) the optimum gauge den...
Selected Effects of Field Variability on Predictions from a Soil Water Finite Difference Model
Field Variability Predictions Soil Water Finite Difference Model
2009/10/28
Known field variability of soil hydrologic parameters is incorporated into a
general finite difference scheme for the prediction of near surface soil water
conditions, including runoff. It is shown ...
Annual Variability in Summer Evapotranspiration and Water Balance at a Subarctic Forest Site
Annual Variability Summer Evapotranspiration Water Balance
2009/10/26
Evapotranspiration (ET) and precipitation were measured during five summers
(1989-1993 inclusive) at a subarctic forest site near Churchill, Manitoba, Canada.
Mean daily ET varied from 2.14-3.18 mm ...

Rainfall Variability Groundwater Recharge Semi-Arid Tanzania
2009/10/26
A conceptual model of the effects of rainfall variability on groundwater recharge
was developed and applied to a small forested catchment in semi-arid Tanzania.
The model simulated dual-domain recha...
