Description

In some urban areas of Prishtina and a large part of the city of Fushe Kosova in recent years are present frequent spates with a tendency to occur floods, especially in the lower parts of these two cities. Rapid urban development in terms of construction and road infrastructure without an adequate system for transporting and discharging the stormwater are a factor for these phenomena. Climate change also indicates a significant increase in rainfall in this region. Data from the Hydrometeorological Institute of Kosova shows that the rainfall for the period 1948-1998 was 606.3 mm while for the period 2000-2018 it is 670.2 mm in the Prishtina station. It is estimated that there are much more frequent occurrences of rain with a short duration that are having a very high intensity. Data collected shows that in 2019 for a 10 min duration the precipitation we had 19.8 mm while in 2021 the amount of precipitation was 11.94 mm. It can be found that there is a high probability that precipitation higher than 15 mm for 10 minutes will be repeated in less than 20 years. The data processed in this study also show a significant increase in construction areas while there is a decrease in green areas, especially in urban areas. This increase of construction areas in the last 20 years by over 10 km2 while reducing the green areas has directly affected the occurrence of spates and in some cases floods that lasted for several days. This also directly reflects the increase in the flow coefficient and the rapid onset of the flood wave in the lower parts of Prishtina and Fushë Kosova. Influencing factors are also the dimensions and condition of the two covered rivers of Prishtina and Vellusha. The study shows that there is a high probability that the covered rivers, streams, and especially the collector of Prishtina will not withstand the amount of rainwater. The consequences will be rapid floods with significant damages. The critical part is the entrance of the covered stormwater collector of the Prishtina river, where a solution is proposed by construction of several small dams that will regulate the flow of the river Prishtina before entering the urban part

Influencing factors in the occurrence of floods in the urban areas of Prishtina and Fushë Kosovë
