Software analysis for the hydraulic calculation of storm-water drainage gravity-flow networks comprising electronic model development

Abstract

In accordance with the Resolution of the Russian Federation Government N 782 “Concerning the Development of Water Supply and Wastewater Disposal Systems”, the development of surface run-off disposal systems comprising the electronic model, is a topical issue for the design and operation of wastewater disposal systems for the Russian settlements. In this context, the software used must provide making the hydraulic calculations for the gravity-flow systems of storm-water drainage networks. [1]. The analysis of Russian software [2-4] revealed the impossibility to develop electronic models and to make hydraulic calculations for the gravity-flow networks of storm-water drainage systems. In this connection, the possibilities offered by the foreign software products, which electronic models make it possible to carry out the required hydraulic calculations and to design surface run-off disposal systems, were studied [5,6]. This article contains the analysis of the European document BS EN 752:2008 [7] with regard to determining the flow of surface (storm-water) run-off, as well as the calculations made by the authors, which reveal that foreign software products are not applicable in Russia. Nevertheless, for the development of the electronic model for the hydraulic calculation of a storm-water drainage system, some mathematical relationship was found that most adequately characterizes the type of surface run-off hydrograph, most typically occurring on the territory of the Russian Federation in cases of atmospheric precipitation fallout. This relationship comprises the application of the RTK hydrograph method.
