The paper discusses water balance data for a small (16 km2) boulder clay
catchment. In order to check the accuracy of the calculations, water balances
are cast for different, overlapping periods of ...
POTENTIAL EVAPOTRANSPIRATION AND WATER BALANCE IN ICELAND
POTENTIAL EVAPOTRANSPIRATION WATER BALANCE ICELAND
2009/10/29
The paper describes the results of estimations of potential evapotranspiration
(ED) in Iceland using Penman's equation. The calculations are based
on distribution maps for global radiation for the p...
GROUNDWATER DEVELOPMENT AND ITS INFLUENCE ON THE WATER BALANCE
GROUNDWATER DEVELOPMENT INFLUENCE WATER BALANCE
2009/10/29
Lowering the head of an artesian aquifer in Zealand, Denmark by pumping
of groundwater is shown to affect the water balance.
Based on known amounts of groundwater being developed, the coefficient
o...
A DETERMINISTIC PARAMETRIC WATER-BALANCE MODEL
DETERMINISTIC PARAMETRIC WATER-BALANCE MODEL
2009/10/29
A simple deterministic model, that needs little input-data, is derived. It is
based on an analysis of the recession curve, where new considerations are
introduced. Input data consist ol time-series ...
PROCEDURES FOR EVALUATING THE SURFACE WATER BALANCE OF GRAN CANARIA
PROCEDURES SURFACE WATER BALANCE GRAN CANARIA
2009/10/29
To evaluate the surface water balance in Gran Canaria, standard procedures
were modified to fit local conditions, taking into account the availability
and quality of data as well as the special feat...
The summer water balance in a Danish oak forest was studied during a period
of 5 years. Interception reduces rainfall inside the forest by about 15%. Variations
of the saturated soil moisture amount...
The Role of Soil Moisture in the Water-Balance of a Small-Clay Catchment,1967-75
Soil Moisture Water-Balance Small-Clay Catchment
2009/10/27
An eight year run of detailed soil moisture data has been incorporated into
simple water balance calculations in an attempt to estimate actual evapotranspiration.
The value of this data is shown whe...
Annual Variability in Summer Evapotranspiration and Water Balance at a Subarctic Forest Site
Annual Variability Summer Evapotranspiration Water Balance
2009/10/26
Evapotranspiration (ET) and precipitation were measured during five summers
(1989-1993 inclusive) at a subarctic forest site near Churchill, Manitoba, Canada.
Mean daily ET varied from 2.14-3.18 mm ...
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 ...
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...

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...
