erosion. Even arable land of plains, which are covered with an enormous soil-cover (up to 7 m terra rossa in the southern province Huna) are wasted by increase in gully formation.
This study covers the regional and settlement features of telefax facilities installed in Hungary. The introduction of this innovation started late in Hungary, compared to the West, and the process was greatly hindered by the low standards
A synthesis with an ecological characterization of the vegetation cover in Romania, related to the geographical conditions. The vegetation map of Romania (1:2 000 000) included in this book will be used for the vegetation map of Europe, in course
A probabilistic fire-protection siting model is described that places capacitated stations, engine companies, and truck companies in such a way that the population or calls covered by an engine and a truck with a joint reliability is maximized.
This study covers the regional and settlement features of telefax facilities installed in Hungary. The introduction of this innovation started late in Hungary, compared to the West, and the process was greatly hindered by the low standards
A review of information on the occurrence, classification, properties and genesis of soils, pedogenic duricrusts and unconsolidated sediments covering pan floors and margins. A three-fold division based on climate was establisehd. - (AJC)
containing lacustrine-boggy deposits of Allerød-Holocene age, as well as on the occurrence of ventifacts and covers of radiocarbon dated Plenivistulian anemoclastic silty-clayey sediments, a dozen metres thick.
The slow movement of the soil depends on local factors (slope angle, moisture of the soil, vegetation cover) and on the latitudinal and altitudinal climatic zonal factors (temperature, precipitation). The rate of soil movement in the polar
The AA. assert that only through profitable management of forests for timber and non-timber products can forest cover be maintained in competition with pressures to convert forest land to other uses. This sustainability concept is important, since
The generalization of the data available, field and laboratory investigations made it possible to estimate the pesticide in flow with large rivers to the NW part of the Black Sea, and the degree of pollution of the soil cover, bottom sediments
Multiple glaciations are probable in Scandinavia for various reasons, but all glaciations do not need to have covered the whole area. The glacial gross forms are tested, first in general. The great contrast between areas W and E of the mountains
SPOT satellite images from the dune fields reveal areas of poor vegetation and even areas without vegetation within a more or less non-influenced vegetation cover. Causes for the absence of vegetation are overgrazing and agriculture arranged
The radical change in forest policy has profound implications for the West Coast, and an alternative to the conventional forest management framework is required which recognises the Government's desire to protect the indigenous forest cover, yet
Remarks on solar radiation, winds (average of 105 foehn days/yr), air temperatures (lowest minima in basin - 40,4 deg. C.); snow cover (290 days on highest peaks); and climatic change. - (DWG)
This section presents quantitative data on some physiographic characteristics of the basin of the Reventaźon river upstream of the gauging stationat the Guayabo planned dam site. This region covers the most important area from the viewpoint
The soil erodibility factor K used in the Revised Universal Soil Loss Equation can be calculated by two general applicable models. Data on the various soils covering northern Belgium are processed to evaluate the use of these models. Erodibility
