Digital model of groundwater technogenesis as an element of sustainable development of the urban environment

Alexander I. Semyachkov, Konstantin Al. Semyachkov

The purpose of this study is to create a digital twin of the sludge reservoir, which allows modeling and predicting the impact of technogenic formation on the sustainability of urban development, in particular, on the state of groundwater. The research methodology is to simulate groundwater based on numerical simulation using the ModTech 2.21 program. This program is designed to solve problems of various equations and partial derivatives that describe the geo-filtration of the environment, using a numerical method on a three-dimensional finite-difference grid. In order to assess the sustainable development of the urban environment in the city of Sterlitomak, a digital twin of the urban area was created in terms of groundwater. Sludge accumulator «White Sea» is a unique man-made object located in the city of Sterlitomak and affecting groundwater due to infiltration losses of distiller fluid through the bed of the sludge reservoir. According to the simulation results, the infiltration losses of the SHBM are 3078 m3/day or 1123470 m3/year. The incoming part of the balance is formed due to the attraction of river runoff, infiltration nutrition, and the outgoing part is due to the discharge of groundwater into surface water. The model assessment was carried out in relation to the conditions of migration of the main pollutant component in the territory of the «White Sea» - chlorides. With the help of the created digital model, it is possible to assess, predict and manage the situation in the urban environment in terms of groundwater. Digitalization through the use of intelligent solutions and innovations in the field of digital technologies makes it possible to understand the processes occurring in social, man-made, and natural systems at a new level. The next step in creating digital twins can be models of electronic maps of soil cover or vegetation, the state of the air basin, and more. The same models can be created on the basis of economic and social indicators. This is necessary for planning the sustainable development of the urban environment.
