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
2010/2/20
The Tropical Rainfall Measuring Mission (TRMM) carries aboard the Precipitation Radar (TRMMPR) that measures the backscatter (σ°) of the surface. σ° is sensitive to surface soil moisture and vegetatio...

Modeling the Effects of Rainfall Variability on Groundwater Recharge in Semi-Arid Tanzania
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...
The aggregate description of semi-arid vegetation with precipitation-generated soil moisture heterogeneity
Biosphere-Atmosphere Transfer Scheme semi-arid vegetation soil moisture
2009/6/8
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...
Analysis of effective resistance calculation methods and their effect on modelling evapotranspiration in two different patches of vegetation in semi-arid SE Spain
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 ...
Analysis of soil and vegetation patterns in semi-arid Mediterranean landscapes by way of a conceptual water balance model
semi-arid Mediterranean water balance model vegetation types
2009/5/4
This paper investigates the impact of various vegetation types on water balance variability in semi-arid Mediterranean landscapes, and the different strategies they may have developed to succeed in su...
The HYDROMED model and its application to semi-arid Mediterranean catchments with hill reservoirs 3: Reservoir storage capacity and probability of failure model
HYDROMED reservoir storage capacity
2009/3/24
This paper addresses the issue of "what reservoir storage capacity is required to maintain a yield with a given probability of failure?". It is an important issue in terms of construction and cost. HY...
The HYDROMED model and its application to semi-arid Mediterranean catchments with hill reservoirs 2: Rainfall-runoff model applications to three Mediterranean hill reservoirs
HYDROMED rainfall-runoff model
2009/3/24
The objective of this work was to assess the performance of the newly developed HYDROMED model. Three catchments with hill reservoirs were selected. They are El-Gouazine and Kamech in Tunisia and Es S...
The water balance of two semi-arid shrubs on abandoned land in South-Eastern Spain after cold season rainfall
water balance neutron probe patchy vegetation
2009/3/17
The inland, mountainous marginal areas (land abandoned by farming and colonised by shrubs) of the Iberian Peninsular, Spain, generally receive a higher rainfall than the coastal areas (Lazaro and Rey,...
Determination of soil hydraulic properties using pedotransfer functions in a semi-arid basin, Turkey
soil hydraulic properties soil characteristic curves
2009/3/11
Spatial and temporal variations in soil hydraulic properties such as soil moisture q(h) and hydraulic conductivity K(q) or K(h), may affect the performance of hydrological models. Moreover, the cost o...
Derivation of temperature lapse rates in semi-arid south-eastern Arizona
near surface lapse rates semi-arid climate
2009/3/11
Ecological and hydrological modelling at the regional scale requires distributed information on weather variables, and temperature is important among these.
