In about half of the Dutch coastal dunes, the former wet slacks have dried during the last 100 years. The purpose of this study was to find causes of drying. A fall in water table was the major cause, others were coastal erosion, increase
in evaporation, extraction of groundwater. In some dried areas surface water from elsewhere is infiltrated for later recovery for the use as drinking water. Vegetation of dried slacks which get wet sometimes is of a ruderal character and atypical of dunes.
Dried earth layers of artificial forestland in the Loess Plateau of Shaanxi Province
By determining the earth moisture content of artificial forestland between 0 and 6 m deep in the Loess Plateau of Shaanxi province, the vertical change of moisture content, distribution and formation causes of a dried earth layer are researched
. The dried layers generally develop in middle-aged artificial forestland that consumed too much moisture.

Etude géographique et historique des villages de dries en Belgique. Les driesen et l'habitat qui leur est lié remontent aux VII-IX s. Si les villages de dries n'ont qu'un rôle mineur dans l'habitat rural de cette région, ils représentent une forme
. The TMEMs were used to record changes in surface elevation as the rocks dried during the remainder of the 12 h of a semi-diurnal tidal cycle. A similar technique was used on the same rock types at intertidal TMEM stations in the field, as the rock dried
Periglacial landforms in southern Africa and the alpine zone of Colorado and New Mexico are compared. Lower altitudinal features in southern Africa reflect a drier environment. - (AJC)
and then oven-dried to simulate natural weathering. The results indicate that is difficult to predict the weathering behaviour of combinations of salts from the weathering behaviour of the salts individually. Possible causes of enhanced weathering by some
The AA. have chosen a site which is much drier (70 mm mean annual rainfall) than the main zone of loess sedimentation (Yaalon and Dan, 1974) to study dust trapping. The mosses grow over the particles covering them and trap additional dust
An examination of management practices in the Park revealed a number of deficiencies with regard to burning and game reduction schemes. More attention needs to be directed towards the drier areas. Suggestions are offered. - (AJC)
Although large dimension tufa deposits are widely distributed throughout drier karst areas of Southern Africa, active tufa precipitation is rare. This report records a site of limited, but rapid tufa deposition at Gorrokop on the Gaap Plateau
Most scenarios of greenhouse-gas climatic change predict a warmer drier Great Plains environment. The goal of this research was to determine the resulting change in soil moisture and to relate this to changes in agricultural productivity. Soil
a polygenesis of the weathering mantle during the Tertiary, due to descending groundwater tables caused by the beginning tectonic uplift of the Rhenish Massif and drier climatic periods during the Middle Tertiary. Periglacial processes during the Pleistocene led
Although now intensely arid, the western slope of the Atacama Andes of northern Chile had wetter and warmer conditions during the early Holocene. After about 3 000 yr. B.P. conditions again became drier. Heavy use today of fossil groundwater
of the impact of climatic change in semi-arid and arid areas. The study focuses on the case of a change from drier to wetter conditions, a transition which was accompanied by loess penetration into the northern Negev desert.
The Gongga Shan range is in the transition zone between the Tibetan Plateau and the South Chinese plains. Western slopes are warmer and drier than the eastern slopes at the same altitude, which author attributes to the mass-elevation effect
