Problems of High Water Appearances in Urban Areas

Flood appearance in urban areas is commonly caused by the urban areas precipitation’ s themselves. The reason for their appearance is often inevitable e.g. extreme rainfalls, hydrological runoff conditions or the degree of drainage systems development, but sometimes the damages caused by flood appearance are the result of methodological mistakes in hydrological calculations. Present paper analyses high water appearances in urban areas from the aspect of hydrological practice. The most frequent causes of high water appearances are presented and much more detailed evaluation of problems of high waters in urban catchment areas as the consequence of precipitation is performed. The main principles of drainage systems planning for negative effect elimination of high waters is described. The emphasis is given on the hydrological component of the mentioned problem. The actual problem of urban precipitation water drainage system planning is given on the example of Škurinjski potok catchment area in Rijeka.
