RainyDay

Rainfall for Modern Flood Hazard Assessment

Welcome to Web-based RainyDay Beta! RainyDay is a framework for generating large numbers of realistic extreme rainfall scenarios based on remotely-sensed precipitation fields. It is founded on a statistical resampling concept known as stochastic storm transposition (SST). These rainfall scenarios can then be used to examine the extreme rainfall statistics for a user-specified region, or to drive a hazard model (usually a hydrologic model).

This web-based version of RainyDay is intended to make the software more accessible. We highly recommend reading the related publications and the supporting documentation and example “.sst” file here, and viewing the related YouTube videos here. The “Basic Version” includes a graphical mapping interface but otherwise very limited options. THE BASIC VERSION IS INTENDED FOR DEMONSTRATION PURPOSES ONLY! The “Advanced Version” provides most of the features available in the standalone version of RainyDay. For users who intend to perform detailed analyses, we recommend the configuring the standalone version of RainyDay, available on Github. Please contact us if you have questions or comments about this web interface. RainyDay is published under the MIT License for open source distribution (see https://opensource.org/licenses/MIT/).
