Description:
Abstract:
This data publication contains a vector digital file of modeled 100-year flood zones for Front Range National Forests in Colorado and a tabular digital file containing flows rates (cubic feet per second) for different return intervals. Flow rates are based on 1994-2018 stream flows, but flows are not stationary and will change with changing precipitation patterns. This one method may not identify 100-year floodplains and discharge rates correctly and is best applied in conjunction with other lines of evidence. Additionally, models will improve with time.
Purpose:
Provides an 100-year inundation map for Front Range National Forests.

Attribute_Accuracy:
Attribute_Accuracy_Report:
This model is the only available inundation map for Front Range National Forests. However, the modeling process remains under development, including corrections of the digital elevation model. Error also may result from bias in the National Water Model streamflow predictions.
Completeness_Report:
There are no missing data.

Flow rates for NHD stream reaches
Process_Step:
Process_Description:
The National Water Model (NWM version 2.0) simulates hourly water flow for 2.7 million stream locations (National Hydrography Dataset; NHDPlusV2) based on more than 8,000 U.S. Geological Survey gauges in the contiguous United States (NOAA Office of Water Prediction 2019; https://water.noaa.gov/about/nwm; https://registry.opendata.aws/nwm-archive/). We used the (1994 to 2018) retrospective simulation to extract the maximum flow rate for each stream reach. We then applied the USGS bulletin 17B flood frequency analysis method (IACWD 1982) to determine discharge rates, from the log-Pearson Type III frequency distribution. We supplied discharge rates at multiple intervals, including 100 years, for about 5000 stream reaches. To determine area and height of inundation, we used the height above nearest drainage (HAND) method and HAND data (Zheng et al. 2018), based on hydrologic terrain to estimate inundation rather than more computationally intensive modelling. We applied synthetic rating curves from the HAND raster to convert the 100-year flowrates to corresponding water levels (Zheng et al. 2018), using the Manning's equation with a predefined channel roughness value 0.05.
