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...
Relating surface backscatter response from TRMM precipitation radar to soil moisture:results over a semi-arid region
surface backscatter response TRMM precipitation radar soil moisture

Meteorological measurements in the Walnut Gulch catchment in Arizona were used to synthesize a distributed, hourly-average time series of data across a 26.9 by 12.5 km area with a grid resolution of 4...
Mosaic versus dual source approaches for modelling the surface energy balance of a semi-arid land
semi-arid land surface energy balance Two-layer parameterisation
2009/5/26
Two-layer parameterisation of the surface energy budget proves to be realistic for sparse but homogeneously distributed vegetation. For semi-arid land surfaces however, sparse vegetation is usually in...
Eco-geomorphology of banded vegetation patterns in arid and semi-arid regions
banded vegetation patterns semi-arid regions arid
2009/5/13
The interaction between vegetation and hydrologic processes is particularly tight in water-limited environments where a positive-feedback links soil moisture and vegetation. The vegetation of these sy...

effective resistance calculation methods evapotranspiration semi-arid SE Spain
2009/5/13
Effective parameters are of major importance in modelling surface fluxes at different scales of spatial heterogeneity. Different ways to obtain these effective parameters for their use in meso-scale ...
A conceptual dynamic vegetation-soil model for arid and semiarid zones
vegetation-soil model semiarid zones arid
2009/5/6
Plant ecosystems in arid and semiarid climates show high complexity, since they depend on water availability to carry out their vital processes. In these climates, water stress is the main factor cont...
