Spatial Variability of Groundwater Recharge - I. Is it really variable?
Spatial variability Groundwater recharge Sri Lanka
2015/1/4
The spatial variability of recharge is an important consideration in estimating recharge especially as all methods of estimating it are 'point' estimates and in most places recharge varies in space. T...
Spatial Variability of Groundwater Recharge - II. Factors Affecting Variability and Taking Account of it in Estimating Recharge
Spatial variability Groundwater recharge Sri Lanka
2015/1/4
The accompanying paper provided evidence to suggest that spatial variability of groundwater recharge is ‘true’ variability. This paper attempts to determine the major causes of such variability even a...

Quantifying the impact of groundwater depth on evapotranspiration in a semi-arid grassland region
groundwater depth evapotranspiration semi-arid grassland
2011/3/15
Interactions between shallow groundwater and land surface processes play an important role in the ecohydrology of riparian zones. Some recent land surface models (LSMs) incorporate groundwater-land su...
Analysis of the impact of climate change on groundwater related hydrological fluxes: a multi-model approach including different downscaling methods
groundwater related hydrological fluxes multi-model approach
2011/1/7
Climate change related modifications in the spatio-temporal distribution of precipitation and evapotranspiration will have an impact on groundwater resources. This study presents a modelling approach ...
Groundwater use for irrigation – a global inventory
Groundwater irrigation global inventory
2010/12/22
Irrigation is the most important water use sector accounting for about 70% of the global freshwater withdrawals and 90% of consumptive water uses. While the extent of irrigation and related water uses...
Groundwater fluctuations in heterogeneous coastal leaky aquifer systems
Groundwater fluctuations heterogeneous coastal leaky aquifer systems
2010/12/22
In the past, the coastal leaky aquifer system, including two aquifers and an aquitard between them, was commonly assumed to be homogeneous and of infinite extent in the horizontal direction. The leaky...

Policy for water resources impacts not only hydrological processes, but the closely intertwined economic and social processes dependent on them. Understanding these process interactions across domains...
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...
