In rural areas the 100-year flood of smaller watersheds has a strong
dependence on the permeability of the geologic subsurface of the watershed
and on the point rainfall intensity.
Based on 70 000 ...

The magnitude of reject heat, the distances to which sensible heat cffects may be experienced in a river and alternate means of rejccting heat are
discussed.Steam electric generating stations, fossil...
THE EFFECT OF SHELTER BELTS AND IRRIGATION ON WATER USE IN A DRY REGION
SHELTER BELTS IRRIGATION WATER USE DRY REGION
2009/10/29
This article describes an investigation of irrigation and water use in an
area with wooden shelter belts. Soil moisture was measurcd using a
neutron moisture probe and tensiometers. The soil is dccp...

Seasonal Variability Pole-to-Pole Water Vapor Balance IGY
2009/10/29
A study of the vertically integrated fields of water vapor and its transport on a
planetary scale derived from aerological data taken during the IGY (International
Geophysical Year) is presented. Th...
Water in permafrost areas is available to the organisms during a short time and
in a restricted space. Models of soil water occurrence and flow are applicated as
basis for analysis of moisture in th...
The development and application of a digital computer model of the ground water reservoir of the island of Anholt is described.
The model is based on a finite difference, two-dimensional approach. It...

Ionic Composition Ground Water Precipitation Upper Romerike District
2009/10/29
In the Upper Romerike District the lakes possess widely different chemical characteristics
depending on their hydrological conditions. The most dilute lakes are fed
only by precipitation, and the mo...
A two-dimensional horizontal hydrodynamical model has been used to estimate
the changes that a harbour road will cause in the water exchange of an
estuary. The research area has been the Kokemaenjok...
