Summary
Digital flood-inundation maps for a 6.7-mile reach of Joachim Creek within and near the City of De Soto, Missouri, were created by the U.S. Geological Survey (USGS) in cooperation with the City of De Soto, Missouri. The flood-inundation maps depict estimates of the spatial extent, depth, and velocity corresponding to select flood events. Flood elevations were computed for Joachim Creek by means of a two-dimensional, finite-volume numerical model for river hydraulics. The hydraulic model was calibrated by using global positioning system measurements of water-surface elevations of high-water marks from the April 18, 2013 flood and the maximum measured discharge at the USGS streamgage Joachim Creek at De Soto, Missouri (station number [...]
Summary
Digital flood-inundation maps for a 6.7-mile reach of Joachim Creek within and near the City of De Soto, Missouri, were created by the U.S. Geological Survey (USGS) in cooperation with the City of De Soto, Missouri. The flood-inundation maps depict estimates of the spatial extent, depth, and velocity corresponding to select flood events.
Flood elevations were computed for Joachim Creek by means of a two-dimensional, finite-volume numerical model for river hydraulics. The hydraulic model was calibrated by using global positioning system measurements of water-surface elevations of high-water marks from the April 18, 2013 flood and the maximum measured discharge at the USGS streamgage Joachim Creek at De Soto, Missouri (station number 07019500). The calibrated hydraulic model was then used to compute the hydraulic conditions associated with the 10-, 4-, 2-, 1-, and 0.2-annual exceedance probability (AEP) flows (10-year, 25-year, 50-year, 100-year and 500-year recurrence interval). The water-surface elevation, velocity, and water depth maps associated with the 1- and 0.2-percent AEP flood events are available in GeoTIFF format. The hydraulic model is available as a model archive.

This dataset was created to support the development of flood inundation maps for probabilistic flows corresponding to the 10-, 4-, 2-, 1-, and 0.2-percent annual exceedance probability flows for a reach of Joachim Creek, DeSoto, Missouri.
