Assessing environmental threats being a consequence of floods from sewage systems is particularly relevant in light of climate change occurring in recent decades. The potential threats can be demonstrated only by hydrodynamic modeling. The main problem while simulating sewage systems operation is the selection of proper model rainfall. It should reflect the main characteristics of real rainfall phenomena occurring in the analyzed area. In Poland, regarding the lack of local models, the model rainfalls developed in Germany are recommended for use. However, there was no confirmation so far, whether these models correspond to Polish hydrological conditions. The aim of the work was, therefore, the verification of these rainfall standards through research on the variability of precipitation intensity over time, based on local databases. Statistical analysis of local hyetographs shapes indicated differences with the German standards. On this basis, detailed model rainfall patterns for the studied stations were proposed.

鉴于近几十年来发生的气候变化，评估污水系统洪水造成的环境威胁尤其重要。潜在威胁只能通过流体动力学建模来证明。模拟污水系统运行时的主要问题是选择合适的模型降雨。它应反映分析区域内发生的实际降雨现象的主要特征。在波兰，由于缺乏本地模型，建议使用德国开发的模型降雨。但是，到目前为止，这些模型是否符合波兰的水文条件尚无定论。因此，该工作的目的是通过基于当地数据库的降雨强度随时间变化的研究，验证这些降雨标准。本地hyperographs形状的统计分析表明与德国标准的差异。在此基础上，提出了研究台站的详细模式降雨模式。
