Design of detention spaces in the Ulička and Ublianka River catchment

Abstract

Based on morphological and hydrological data, a hydrodynamic model of surface water flow was created in the HEC-RAS program. The model simulated a 100-year flood wave propagation in the basins of the Ulička and Ublianka streams as a part of the upper Uzh River catchment. After calibration, protection measures were added to the model whose task was to transform the flood discharge. For the transformation of the flood wave, detention and multi-purpose reservoirs were proposed, which could improve the flow rates in the riverbeds in times of drought. The proposed measures were selected on base of the terrain recognition of the research team in September and October 2021 in several profiles of mentioned rivers as well as on their tributaries.
