A Study on Storm-water reservoir for flood control as biodiverse habitats in Urban Area

A system of reservoirs is usually defined as a system of water management elements, that are mutually linked by inner and outer connections in a purpose-built complex. Combined elements consist of reservoirs, river sections, dams, weirs, hydropower plants, water treatment plants and other hydraulic structures. These elements also include the rainfall system, the run-off system, the ground water system, etc. A system of reservoirs serves many purposes, which result from the basic functions of water reservoirs: storage, flood control and environmental functions. Most reservoirs serve several purposes at the same time. They are so called multi-purposes reservoirs. Optimum design and control of a system of reservoirs depends strongly on identifying the particular purposes. In order to assess these purposes and to evaluate the appropriate set of criteria, risk analysis can be used. Design and control of water reservoir functions is consequently solved with the use of multi-objective optimisation. This paper deals with the use of the risk analysis to determine criteria for controlling the system. This approach is tested on a case study of the Pastviny dam in the Czech Republic.

Urban Storm

The possibilities of generating electric power from relatively small hydro-electric sources in a large urban area is investigated. Two different aspects of hydro-electric sources have been studied: storm/waste water pipes in large multi-tenanted residential buildings and urban storm water discharge area (CSI area). The potential to generate from these sources has been investigated using a micro-turbine. The potential electric power which could be extracted from the sources was estimated using energy conservation equations under normal engineering assumptions. While technically feasible, all options are shown to be uneconomic in practice.

The City

The urban flood control should be regulated according to the topography, rivers and the regional economics of the city. The regulating reservoirs will be built or rebuilt in the mountain area upstream; the flood would be drawn downstream through the diversion channel. The flood in city would be reduced. The program would to control the rivers in urban area, reduce the elevation of rivers downstream by the non-engineering measure in order to decrease the effect of the backwater. In this paper, we suggested that the program of artificial damaged embankment and the flood compensation foundation as the main measures for flood control in urban area. The safety of the urban area will be ensured by both engineering measures and non-engineering measures from the flood of the rivers.
