scooters Relevance of the work is caused by the increase in the role of human factor in development of flooding areas.In recent years, in Omsk region spring flood exposed to a large quantity of settlements, including areas with satisfactory conditions.One of these settlements is Tyukalinsk where there are serious flooding problems in the last four years, that influenced the choice of the research object.The aim of the study is to identify the causes of deterioration of spring flood situation, to search for solutions to flooding stabilization taking into account the presence of the river, carrying out the natural drainage area.The methods: analysis of long-term observations of groundwater in the wells of regime subsurface condition of monitoring network taking into account the amount of precipitation, identification of graphical-analytical dependencies and causality.

Results.The authors have analyzed the long-term changes in groundwater levels, which enter into the river Tyukalka.They study the values of precipitation in the given territory for the periods of surveys.The causes of slow withdrawal of meltwater in spring and the accumulation of groundwater to the many years were identidied.Despite the relatively high elasticity of admission and expenditure parts of the water balance (precipitation - surface water - groundwater) and high capacity for allotment of excess water by transit (crossing the city) Tyukalka river, numerous man-made structures such as carrying water Protection pipes, dams, bulk bridges, road and many others, contribute significantly to the natural drainage, reducing the expenditure side of water balance.

Regulation of river flow leads to poor drainage of both surface and groundwater, increasing the risk of flooding and the duration of the spring flood.
