The article presents the results of recent research on denudational processes within two dry valleys in the central part of the Niemczańsko-Strzelińskie Hills (Sudetic Foreland), in the context of all previous studies on denudation from slopes under agricultural use in that region. The aim of the study was to estimate the intensity of morphogenetic processes acting on slopes in the agricultural landscape of the Strzelińskie Hills. On the basis of geomorphological mapping of two dry valleys, the rate of denudation during spring season was calculated as 0,5-1 mm. This value is similar to the amount of denudation calculated previously by other author for the vicinity of Henryków during the episodes of torrential rainfall. Dry valleys in upper parts of the Strzelińskie Hills develop due to annual episodic concentration of surface wash, especially during spring thaw.
