Abstract. Many floodplains are excluded from urban development because the floods cause considerable damage to people's lives and properties. This requires the development of new approaches to flood management and mitigation for support sustainable urban development. In present study as the measures for mitigation of flash floods, the regulation of river flow by the system of detention reservoirs for flood diversion with dams, which do not need any operation management, are analyzed concerning of Far East region of Russia. The main objective of this paper is to develop a method for analysis how the dam site selection meets the environmental criterion. The method to justify a selection of self-regulated flood dam parameters, primarily a height of a dam and its location on a water stream, providing minimization of impact on the environment have been developed. The result for Selemdzha river basin in Far East monsoon region of Russian Federation is analyzed. The result shows the robustness of the method.
A systematic approach to reducing the risk of flooding is considered. The main idea of it is to switch from the flood control only by the one hydro system on the main river but to control the whole river system, including many adjacent river basins at various levels. This proposal expands the possibility of using a flood control system of self-regulating hydro systems distributed on adjacent drainage basins at multiple levels by organizing their joint work, ensuring that the maximum allowable water flow in the control sections of the river system is not exceeded. Using the proposed approach will allow protecting from flooding significant areas of land in the lower pool of the main hydroelectric complex in the context of climate change.
The article analyzes the results of modeling the regulation of flood flow in a river basin by the flood control facility on a side tributary of the river under conditions of climatic changes. The use of geographic information system for assessing the impact of the flood control facilities on the environment when justifying their parameters is considered. The need to create anti-flood hydro systems on side tributaries exists because the water capacity of existing and projected hydro systems may not be enough to transform the flood in conditions of economic and climatic changes. The problem arises of determining the required water capacity of the flood control facility and its location considering environmental requirements.
This article discusses the organization and the results of the laboratory-scale experiments in bioreactors with samples of municipal solid waste (MSW) for assessment of biogas potential and leachate emissions for MSW landfills energy reclamation with the aim of sustainable urban development. The procedure of organization and carrying out laboratory experiments on MSW decomposition in bioreactors providing similarity to MSW landfill conditions was approved using equipment meeting the international requirements.
