Projects at Rural GIS Sites
Use of Geospatial Data and Methods to Delineate Floodways
RGIS Regional Office: Pacific Northwest, Central Washington University
Project Dates: 2006/2007
Synopsis:
This objective will develop a guidance document on how to delineate floodways for several streams of various types, primarily based on gradient and degree of confinement. Deliverables will include the production of GIS data layers delineating the SMA floodways for several streams of varying types. A report will also be generated describing GIS and field delineation steps; data used and sources available; analysis of the differences between the SMA and FEMA floodways (e.g., area extent); and, what if any, predictive relationships are discovered between stream types and floodway types.
