Comparison of Simulated Water Balance for Willow,Spruce,Grass Ley and Barley
Simulated Water Balance Willow Spruce Grass Ley Barley
2009/10/23
Evaporation from four cropping systems, i.e. willow, spruce, grass ley and barley,
was compared in this simulation study. The physically based soil model had
prev~ously been used to simulate a wide ...
The Effect of Climate Change on River Flow and Snow Cover in the NOPEX Area Simulated by a Simple Water Balance Model
Climate Change River Flow Snow Cover NOPEX Area
2009/10/23
Within the next few decades, changes in global temperature and precipitation
patterns may appear, especially at high latitudes. A simple monthly water-balance
model of the NOPEX basins was developed...
Contributions of Snow to the Annual Water Balance in Moshiri Watershed,Northern Hokkaido,Japan
Contributions of Snow Annual Water Balance Moshiri Watershed
2009/10/23
Characteristics of the water balance were investigated in an experimental watershed
where there is a seasonal snow cover. To estimate the basin-wide snowmelt
by the heat balance method, seven observ...
Interception of a Dense Spruce Forest,Performance of a Simplified Canopy Water Balance Model
Interception Dense Spruce Forest Water Balance Model
2009/10/22
The process of interception was studied in 25-year-old dense stands of Norway
spruce in South Sweden. The throughfall was measured intensively during one
month and extensively during four growing se...
Estimating Soil Moisture in Small Watersheds,Using a Water Balance Approach
Soil Moisture Small Watersheds Water Balance Approach
2009/10/22
Soil moisture content was estimated daily by a energy balance and water budget
(EBWB) analysis of two small subwatersheds in the Walnut Gulch Experimental
Watershed near Tombstone, Arizona. One wate...
Seasonal Water Balance of an Alpine Catchment as Evaluated by Different Methods for Spatially Distributed Snowmelt Modelling
Seasonal Water Balance Alpine Catchment Snowmelt Modelling
2009/10/22
The application of three temperature-index based models and of one energy balance
based snowmelt model was investigated. The snow models were integrated
in the spatially distributed hydrological mod...
WATER BALANCE AND LANDSCAPE DEGRADATION OF AN UNGAUGED MOUNTAIN WATERSHED：CASE STUDY OF THE PICO DE TANCITARO NATIONAL PARK, MICHOACAN, MEXICO
Water balance geographic information system land degradation
2009/10/12
Water balance and its relation to land degradation were investigated by using a spatially distributed model and geographic information system (GIS) in the Pico de Tancitaro National Park, Michoacan, M...
MODELING THE EFFECT OF SOIL AMENDMENTS (COMPOSTS) ON WATER BALANCE AND WATER QUALITY

2009/10/12
Nutrient loadings from agricultural and urban areas have increased nutrient concentrations in water, particularly phosphorus at the Everglades National Park. The soils in the region are mainly crushed...
Simulation of the soil water balance of wheat using daily weather forecast messages to estimate the reference evapotranspiration
evapotranspiration weather forecast soil water balance
2009/7/22
Aiming at developing real time water balance modelling for irrigation scheduling, this study assesses the accuracy of using the reference evapotranspiration (ETo) estimated from daily weather forecast...
The Plynlimon water balance 1969-1995：the impact of forest and moorland vegetation on evaporation and streamflow in upland catchments
Plynlimon water balance moorland vegetation vaporation streamflow upland catchments
2009/6/8
The Plynlimon experiment in mid-Wales, designed to determine the extent to which coniferous plantation increases evaporation losses and reduces streamflow relative to upland grassland, has now been yi...
Determination of evaporation from a catchment water balance at a monthly time scale
evaporation monthly time scale catchment water
2009/6/8
A method is presented to determine total evaporation from the earth's surface at a spatial scale that is adequate for linkage with climate models. The method is based on the water balance of catchment...
30 years of forest hydrology changes at Coalburn：water balance and extreme flows
forest hydrology changes Coalburn extreme flows
2009/6/5
The Coalburn experimental catchment, located in the Kielder Forest in northern Britain, was established in 1967 to study the hydrological impacts of upland coniferous plantation forestry. Results of 3...
