The new method differs from the previous method in several aspects. The locations of water levels and their section criteria for interpolation are more flexible than the previous method. Ability to incorporate user defined flood barriers as coverage provides an excellent opportunity to overcome the limitations inherent in digital terrain models. It also becomes useful in evaluating “what if” or post project scenarios. The new method provides several options to present flood depth data that are not available in the older method. In addition to conceptual and computational differences between two methods, you will also notice following changes while using the new method:

  • The method does not require “streams” in the TIN.
  • Multiple events or water level time series can be read as oppose to a single event. User can choose an event while delineating floodplain.
  • Computed flood depths are stored as TIN data set and saved along with the TIN.
  • Multiple flood depth data sets can be created in a TIN from multiple events.
  • Finally flood extent, classified flood depth, and flood impact coverages can be exported as shapefiles for reporting or other flood management purposes.
