water status has been used empirically to identify a threshold condition for landslide triggering. The model produces a satisfactory level of prediction, particularly for periods of concentrated landslide activity.

Four simulation models are used to estimate the evapotranspiration rates and irrigation water requirements of corn, drybean, soybean and sugarbeet production in the Saginaw Bay basin. The availability of streamflow for irrigation supply is evaluated
in the mass balance equation to determine if the available water resources are sufficient to meet the crop's irrigation water requirements. GIS is used to process and analyze the data sets of soils, climate, and water resource features to provide inputs
Magnitude-frequency analysis of water redistribution along a climate gradient in Spain

The 35S activity of sulfate in water provides an estimate of the residence time of atmospherically deposited sulfate, and assuming conservative response of sulfate along the hydrologic flowpath, 35S activity can be used to approximate the residence
time of water. In this paper, the effect of basin morphology on the release of snowmelt water to surface streams is explored. The activity of 35S is used to compare the estimated ages of water exiting 3 small alpine-subalpine basins in north-central

This paper aims to calculate water balance of an entire tiger bush unit, including bare and vegetated areas, to validate a rain redistribution hypothesis. They monitored measurements of runoff and soil moisture content in each zone composing a tiger
A preliminary study on ecological water demand estimation in the arid region - a case in the Qaidam Basin

This paper emphasized the relationship between environment and water, taking ecological demand water (EWD) in the Qaidam Basin, an inner basin in northwestern China, as a key issue to discuss based on landscape mapping. First, the spatial
heterogeneity of ecosystem can be reflected well by landscape pattern; landscape patterns adjust closely with environmental changes; finally, water condition is the key ecological factor for landscape pattern in the arid region. The landsat TM image of 1:100,000

This paper investigates the performance of selected soil and water conservation measures in the highlands of Ethiopia and Eritrea, namely Fanya Juu, soil/stone bund, grass strips and double ditches. The impact of these techniques on runoff, soil
Horizontal water trap for measurement of aeolian sand transport
with water to capture the blown sand. The water trap has high efficiency and does not disturb the wind field or induce upwind scour. Deployment on Padre Island, Texas, indicated that this portable and adjustable trap catches and retains all the sand blown
