Under the influence of widespread reclamation in the second half of the XX century in the river basin of the river Pripyat (Belarus) and global warming there were taking placing place processes which caused lowering of the maximal levels of spring floods and shortening of duration of bottom-lands flooding. In the conditions of the Republic of Belarus there were presented results of estimation of possibility of rearrangement of flooding polders with adjustable duration of flooding into unflooded ones in the area of the bottom land around 495 km from the outlet of the river Pripyat. The results were based on a study of the maximum levels of spring snow melt flood. There were presented marks of the maximal levels of spring flood of the river Pripyat. Reconstruction of flooding polders into non-flooding ones will make it possible to use these lands for all crops, to obey the optimal agronomic sowing terms, to increase the efficiency of agricultural production, and realize agricultural works without regard to hydrological regime of rivers.
