Urban hydrology was created in order to improve methods of managing the runoff of precipitation in towns and protect them from flooding while also protecting public health and environment. The essence of a future solution consists in finding an acceptable compromise of an alternative solution for draining rainwater from a territory. The content of this work is a study focused on resolving the percolation of water from surface runoff and the confrontation between a field test, laboratory analysis, and numerical analysis. By confronting and subsequently proposing conditions for percolation, documents will be created for making urban drainage better and more efficient. The reason for the origin of the subject work follows from the insufficient information on infiltration systems in Slovak technical standards and, likewise, the lack of support for the percolation of water from surface runoff. This work points out the approaches, principles, and fundamentals of a proposal for percolation. The aim of the work is distribution of scientific knowledge in the field of research and solutions for the percolation of water from surface runoff, with emphasis placed on the retention capacity of the selected territory and the intensity of precipitation. A geological study (orientational, detailed or supplementary) must always be conducted with any decision on rainwater percolation in a certain locality. Its range is dependent on the difficulty and type of construction. The preliminary study of areal condition should be focused on detailed engineering-geological and hydrological information. After this work, it is concluded that the percolation of rainwater in urban areas with suitable hydrogeological condition is an effective rainwater management technology as well as protection to congestion of sewer systems.
城市水文学的产生是为了改进城镇降水径流的管理方法，保护城镇免受洪水侵袭，同时保护公众健康和环境。未来解决方案的核心在于找到一种可接受的折衷方案，作为从某一区域排水的替代方案。这项工作的内容是一项研究，重点是解决地表径流的渗流问题，以及实地试验、实验室分析和数值分析之间的对比。通过对比并随后提出渗流条件，将创建相关文件，以使城市排水系统更好、更高效。这项主题工作产生的原因是斯洛伐克技术标准中关于渗透系统的信息不足，同样，对于地表径流的渗流也缺乏支持。这项工作指出了渗流提议的方法、原则和基本原理。该工作的目的是在地表径流渗流的研究和解决方案领域传播科学知识，重点是所选区域的蓄水能力和降水强度。在对某一地点的雨水渗流做出任何决定之前，必须始终进行地质研究（定向、详细或补充）。其范围取决于建设的难度和类型。区域条件的初步研究应侧重于详细的工程地质和水文信息。经过这项工作得出结论，在具有合适水文地质条件的城市地区，雨水渗流是一种有效的雨水管理技术，也是对下水道系统拥堵的一种保护。
