Abstract
The evolution and influence of drainage of too wet lands in the Mūša, Lėvuo, Tatula and Nemunėlis basins located in the Lielupe river
basin district (RBD) on the river runoff in the period of 1960–2011 was analyzed. It was determined the wetland areas in the Mūša, Lėvuo
and Nemunėlis basins exceed 70% and those of the Tatula basin – even 90% of the total basin area. Before 1961, the drainage areas
covered only 4–7% of the territory of the basin and in 2000 these areas covered already 58–80%. Lately, any new drainage systems
almost are not developed, so the drainage areas have changed little.
Water surplus is most intensively removed during spring floods and summer high waters; therefore, due to draining influence the runoff in
rivers varies only during the seasons of the same year.
Keywords:wet land; drainage; river runoff.
