Iowa Flood Risk Model Inventory

What is the purpose of this website?
The Iowa Flood Risk Data Inventory compiles Federal and state agency flood risk models and metadata into a single easily accessible source. Using the Iowa Flood Information System (IFIS) platform inter-agency stream model repository enables statewide ability to quickly access the availability of flood risk models. The geospatial inventory map identifies study reaches that extend through multiple communities. For each model, the posted information includes: 1) Stream name and site description [centerline, study extent]; 2) Type of Model [hydrologic, hydraulic 1D, 2D]; 3) Model level of detail [model/mapping]; and 4) Agency name, point-of-contact, date of model data and model and model properties (datum, etc).

What can be found on the Hydraulic Model Website?
This inventory of Hydraulic models can be used for Floodplain Management. Experience in computational hydraulics is necessary for the use of these models.

The inventory interagency team has established model documentation and review criteria to insure only technically appropriate models are included in the inventory. By maintaining an up-to-date Iowa Flood Risk Data Inventory, all governmental participating partners benefit from sharing the responsibility of posting recently completed model metadata to the IFIS platform. This site identifies models that can be leveraged in a timely manner for additional applications, analysis and expedited flood risk response.

River flooding has been identified as the top priority hazard in the Hazard Analysis and Risk Assessment (HARA) for 2013. Intergovernmental capability to query a flood source inventory of documented hydraulic model availability quickly during times of impending flood threat will reduce and prevent increases in flood risk and increase resiliency.

What is not available on the Hydraulic Model Website?
The inventory includes only detailed hydraulic models and does not replicate the FEMA map service center or the Iowa Department of Natural Resources Iowa Flood Maps websites. While some of the products created may be adopted by FEMA and become regulatory, maps provided at this link are not regulatory maps. The products are being provided on this site for informational purposes. Iowans interested in map information for flood insurance purposes should visit the FEMA Map Service Center or contact local officials to view the current regulatory map for their jurisdiction.

Important information regarding hydraulic models on the website inventory
All models are provided "as is" without any kind of guarantee as to their accuracy or applicability for a particular purpose. Even though every effort is made to provide accurate information, the user assumes all risks concerning the suitability and accuracy of the models from this web site. These models may contain technical inaccuracies or typographical errors. The model providers assume no responsibility for and disclaims all liability for any such errors in the models.

Who do I contact to have a hydraulic model added to the inventory website?
