Abstract

Floodplain mapping has become an increasingly important part of floodplain management. Floodplain mapping employs mapping software and hydraulic calculation packages to efficiently map floodplains. Modelers often utilize automation software to develop the complex geometries required to reduce the time to develop hydraulic models.

The Utah Inundation Mapping System (UTIMS) was designed to reduce the time required to develop complex geometries for use in floodplain mapping studies. UTIMS reduces the time required to develop geometries used in floodplain management studies. The automated geometries developed include: flood specific river centerlines, bank lines, flow path lines, cross sections, and areal averaged n-value polygons. Utilizing this robust and easy-to-operate software within the GIS environment modelers can significantly reduce the time required to develop accurate floodplain maps. Modelers can thus spend less time developing complex geometries and more time modeling and analyzing floodplains.
