Abstract
The water management of cities and villages faces many challenges. Aging infrastructure systems operate for many years after their theoretical lifetime (operation) with a very high need for reconstruction and repair. The solution is proper rainwater management. The investigated area is part of the cadastral area of the Nitra city. This article is based on the use of geographic information systems (GIS) as tools in proposing water retention measures that are needed to improve the microenvironment of the city. We proceeded in several steps, which consisted of area analysis, survey, surface runoff calculations in urbanized areas, proposal of a suitable solution for given location. For real possibilities of rainwater management procedures, a new site on the outskirts of the city was selected. In the given locality, it was possible to use water infiltration as a solution. The locality has suitable conditions of land ownership, pedological conditions, the slope of the area and also the interest of the inhabitants in the ecological solution. The outlined study indicates the need to continue research on the reliability of rainwater management practices.
Highlights
This study is based on the use of QGIS tools in proposing water retention measures that are needed to improve the city’s microenvironment
The first variant, based on the digital elevation elevation model model (DEM) 5 model, evaluates the area of interest without any obstacles, which means that it does not take into account obstacles in the form of buildings, roads and others
digitalsurface surface model (DSM) 1, which evaluates the area of interest with obstacles in the form of trees, buildings and evaluates the bypass around these areas
Summary
Rainwater management is a fundamental task in urban areas of city infrastructure. The water management infrastructure solution of urban settlements [1]. Has been a fundamental role in planning the structure of the city. In addition to street and road solutions, the most important task was to propose a system of drinking water distribution and drainage of wastewater [2,3]. Water supply has already been recognized in historic cities as one of the greatest challenges for the creation of major cities and administrative centers [4]. The basic tasks of urban planning have been solved since ancient times, such as the ancient cities of Rome, Pompeii, Mesopotamia, ancient India [4,5,6,7]
