Abstract

Urbane poplave se javljaju sve češće uslijed klimatskih promjena i širenja urbanih nepropusnih površina. U radu su analizirane karakteristike oborina na temelju različitih načina namjena korištenja zemljišta (prometna i stambena) i indikatora poplavnih događaja na urbanom području grada Zagreba korištenjem principa graničnih intenziteta. Korišteni su podaci o satnim količinama oborina (Državni hidrometeorološki zavod), intervencijama službi civilne zaštite (Javna vatrogasna postrojba grada... More Zagreba) kao indikatorima poplavnih događaja i namjeni korištenja zemljišta (Zagrebački gradski ured za strategijsko planiranje i razvoj grada). Analizirano je uže područje 4,2 km radijusa oko meteorološke postaje Maksimir. Oborine su analizirane za različita trajanja (1h, 2h, 3h, 6h, 12h i 24h) te su prema podacima o intervencijama detektirani oni kišni događaji koji su potencijalno doveli do poplavnih događaja.za analizirano područje. Određeni su granični intenziteti oborina za sva vremenska trajanja, za zemljišta prometne, stambene namjene te je procijenjena točnost graničnih vrijednosti kao indikatora poplave. Provedene su usporedbe rezultata za prometne, stambene i sve namjene korištenja zemljišta. Dobiveni rezultati mogu poslužiti kao alternativa hidrološko-hidrauličkim modelima za jednostavnije predviđanje opasnosti od poplavnih događaja. Less

Abstract (english)

Urban floods are occurring more and more frequently due to climate change and the expansion of urban impermeable surfaces. This paper analyzes the characteristics of precipitation based on different types of land use (transportation and residential) and indicators of flood events in the urban area of the City of Zagreb using the principle of threshold intensities. Hourly precipitation data (Croatian Meteorological and Hydrological Service), data on civil protection services interventions... More (Public Fire Department Zagreb) used as indicators of flood events, and data on land use purposes (Zagreb City Office for Strategic Planning and City Development) were used. The area of a 4.2 km radius around the meteorological station Maksimir was analyzed. Precipitation was analyzed for different time durations (1h, 2h, 3h, 6h, 12h and 24h) and according to the data on interventions, the rainfall events that potentially led to flood events for the analyzed area were detected. Precipitation threshold intensities for all durations were determined, as well as for transportation and residential land use. Additionally, the sensitivity and specificity of the threshold values as indicators of floods were assessed. Comparisons of results for transportation, residential and all land use purposes were carried out. The obtained results can serve as an alternative to hydrological-hydraulic models for a simpler prediction of flood event risks. Less
