Megjegyzések:	We carried out wind erosion measurements in the field on three sample areas in Nyírség region, and in wind tunnel. During examinations we measured the erosion and accumulation of soil and studied the process, spatial and time pattern of wind and sheet erosion in areas in various geomorphological settings cultivated intensely with different topsoil conditions and with different commercial plant cultures. The surface changes measured in the field measurements verified the fact, that the rate of surface transformation is bigger on bare plough-land, than surfaces are covered by vegetation. The mechanical composition of soils played important role: where soil crust was forming out on the surface, the amount of eroded material was smaller. Erodibility data obtained from wind-tunnel measurements are in accordance with those measured in the field surveys, i.e. the 2-2.5 cm of material loss measured in laboratory were supported by the field measurements. In wetter periods linear and areal erosion of flowing precipitation water had major role in shaping sand surfaces. The performed sheet erosion studies yielded more-or-less similar material loss values, i.e. 0.5-1 cm of material is denuded annually on average from the cultivated wind-blown sand surfaces.

Cím:	Spatiotemporal analysis of the hydrological factors in the subcatchment of the river Tisza, Ne Hungary / Túri Zoltán, Négyesi Gábor, Türk Gábor, Lóki József, Balázs Boglárka, Szabó Szilárd

Megjegyzések:	Research on spatial and temporal changes of hydrological elements of the environment is an important issue of most emerging tasks due to the possible trends of the climate change. In this study we investigated a catchment (Canal Lónyay-főcsatorna) whichwas situated on the northeastern part of Hungary, in the Nyírségmezoregion. We examined some characteristic features of the hydrological elements (precipitation, surface and ground water). To achieve our aims, data measured in hydro-meteorological stations and groundwater gauging wells between 1950-2005, as well as data measured in water-gauges between 1980-2005 were used. We analysed the datasetwith statistical and GIS methods and we illustrated the results on maps and diagrams. About 540-650 mm precipitation was measured on the watershed of Lónyay canal. The effect of the relief was identified in the regional distribution of precipitation. According to the minimum precipitation map, the driest region was the southwestern part of the Lónyay-watershed area. This fact was the consequence of the relative location of the area in a basin (Carpathian Basin with the surrounding mountains). According to our observations the anthropogenic effects presumably does not exceed the influences of natural processes. The connection between gauging wells far from each other indicates regional scale changes on the watershed area.
