Hydrodynamic modeling and GIS tools applied in urban areas

摘要

In connection with resolving the flood issue all of the interested parties endeavour to mitigate the flood negative impacts to the lowest acceptable level. At a time, efforts are exercised to effectively prevent their reoccurrence. The main objective of this paper is to present possibilities of hydrological models and GIS tools in delineating with the flood event threatened urbanised areas. These very areas present the most jeopardised ones. The paper presents conceptual and empirical side of the GIS supported hydrodynamic models in quite a detail. Presented in the paper are results of multiple studies realised within the selected (part of the) basin of river Ol?ava. Proper selection of the way the results will be processed would facilitate to use the attained outputs also in the future process of creating flood - hazard and flood - risk maps.
