Аннотация: . Significant area of Yuzhno-Sakhalinsk city within the riverSusuya flood plain, a terrace above it and its tributaries are located in floodprone zone. The aim of this research was to estimate maximumcharacteristics of flash floods and low-density debris flows for the Susuyariver and its tributaries, the Rogatka and Vladimirovka rivers. A onedimensional model of unsteady water movement based on Saint-Venanequations was used. The modeling of river maximum characteristicsinclude following tasks: 1) collect and analyze the data of past dangerousevents, 2) process the initial information for the model, 3) simulatedischarges of 0.1-10% exceeding probabilities with a change in thehydraulic-morphometric characteristics of the objects. The model does nottake into account flow density, therefore numerical experiments wereconducted with the increasing coefficient of roughness to identify optimalvalues of the parameter. The results can be further used in the constructiondesign of residential buildings and infrastructure in Yuzhno-Sakhalinsk.
