Study of conditions for potential inundation of territories in the period of spring flooding

This article is devoted to research of conditions of potential flooding of territories in the period of the spring flood. The inundations and flooding are most frequently encountered types of flood event. In the wide technical literature such questions as intensity of increase of water level upon flooding, duration of inundation, size of inundated areas, damages inflicted by flooding are considered in detail. But the question on conditions of potential flooding of territories due to inundation is not well considered. In the present article the method for determination of conditions of potential flooding during the spring inundation is suggested and the results of carried out model research are described. It is shown that utilization of known regression dependencies between such parameters of flooding processes as bankfull discharge, the channel width, height of water level, drainage area i.e. the flooded area make it possible to determine conditions of possibility of potential flooding of the area. The brief review of existing regression dependencies between the parameters of inundation processes and the drainage area are given. The condition for potential possibility of the area flooding upon the critical increase of water level in channels is found.
