Modeled Flood Inundation Scenarios for Tuttle Creek Release and Kansas River Levels

To better understand the dynamics of potential flooding on the Big Blue River below Tuttle Creek Reservoir and the Kansas River, the City of Manhattan hired Wood Environmental and Infrastructure, Inc. to create 42 different flooding scenarios based on seven different releases from Tuttle Creek Reservoir and six different river heights on the Kansas River. The flood modeling was done using HEC-RAS 2D.  The modeling report can be found below within the interactive map.  A tutorial on how to use the map and layers is to the right.

Although the modeling was professionally created, the model has not been checked using high levels of quality assurance and quality control standards that normally occur for detailed flood models and engineering studies.  These flood scenarios were created for emergency planning study only to better understand possible scenarios based upon different releases from Tuttle Creek Reservoir and different heights of the Kansas River.  Official information can be found here:
