Requirements for hydraulic modeling of wartime water supply networks and for CBRN pollution risk management

Abstract

Military actions on the territory of Ukraine demonstrated that the termination of centralized water supply can occur both as a result of the direct destruction of water supply facilities, and as a result of power outages, deterioration of water quality at the source, inaccessibility of the water source itself, etc. Therefore, the situation requires the application of completely new approaches to hydraulic modeling, the establishment of new requirements for modeling modes and analysis of the obtained models. Today, the geo-information systems implemented at many Ukrainian water utilities should be used to model adverse scenarios, conduct hydraulic calculations for them, and then determine the optimal ways to improve the situation. There was also a need to conduct hydraulic calculations when developing a response program to chemical, biological, radiation, nuclear (CBRN) water pollution. The analysis of the situation presented in the article allows us to draw a conclusion about the expediency of using Epanet software for this purpose, since specialized software complexes usually do not have the necessary functions. Moreover, for systems that do not have an appropriate hydraulic model, the first stage should be its development, which will include the digitization of the original cartographic information, on-site refinement of distribution networks, determination of network loads, calibration of the model at control points.
