Using ICPR 4.0 to Model 100-year Floodplain in 7 SM Urbanizing Watershed

  • 1.  Using ICPR 4.0 to Model 100-year Floodplain in 7 SM Urbanizing Watershed

    Has anyone had much experience in using ICPR 4.0 in modeling watersheds as large as 7 SM? We have used ICPR very successfully in smaller watersheds, but are curious about other users experience in larger watersheds.

    Hi Karen,

    We have been able to successfully use ICPR 4 in larger watersheds up to about 5 SM that were both urbanized and undeveloped. Our experience with large urbanized watersheds has found that calibrating the model stability parameters can be challenging if a lot of negligible storage elements are present in the model, such as zero-storage nodes representing drainage manholes and catch basins. However, the challenge is not insurmountable.

    If you are able to generate a high-quality DEM to import into the project, then the stage-area and cross-section takeoff tools can save a lot of time in the model development stage.
