This study analyzed the temporal and spatial changes in land use taking place in two adjacent river valleys, located within the Polish Carpathians. The land use in 1977 and 2009 was presented for selected areas. In one of the valleys, a dam has been operating since 1994 along with a retention reservoir, which is an additional factor influencing the direction and scale of the land use changes. An analysis using GIS techniques showed that the general directions of transformation in both valleys in the land use structure are similar but with different intensity. In studied valleys a decrease of area with agricultural land and gradual increase in the forested area have been observed. In the valley with the reservoir few more changes were noticed. The decrease of the forested area by 5.5% and farmland by 8.2% on the areas submerged by reservoir was observed. The strip fields pattern has been changed into more dispersed. The road network development was also observed, as well as the change of nature of residential/agricultural buildings into residential/recreational.

The study discusses accumulation and erosion processes which occurred in the bowl of Włocławek Reservoir in the period 1971-1992, and were analysed using digital batimetric maps. It also provides the results of the work of other authors concerning the assessment of the river sediments accumulated in the reservoir. Analysis of digital batimetric maps has shown that the materiał deposited in Włocławek Reservoir in the years 1971-1992 totalled about 18.3 million m3, which corresponds to approximately 0.87 million m3 of sediments per annum, and means a 4.5% loss of the reservoir's storage capacity. The volume of accumulation and erosion, assessed in this manner, approximates the earlier calculations performed using different research methods; it corroborates the fact that accumulation prevails in the balance of the sediments.
