| Popis: | Satellite based Digital Elevation Models of free availability have been the standard for 2D flood simulation models of large areas. But for small urban areas where high definition and up to date details are needed a different approach must be taken. Digital Surface Models generated with photogrammetry software based on Unmanned Aerial Vehicles imagery is a low cost and high quality solution applicable to this problem. Combined with distributed flood simulation software can give highly detailed results of rain events in urbanized landscapes. In this study, a complete processing workflow is presented to analyze the response to different rain conditions in a complex small area. All the phases are presented, including topographic survey, DEM correction and flood modeling. The solution was applied to a complex environment of semi-urbanized area reproducing even little waterlogged ground depressions. |
