The IAFSM YP Group is excited to invite you to our next webinar. Brian S. Chaille, P.E. CFM and Chris Hanstad, P.E., CFM at the Illinois State Water Survey (ISWS) will be presenting about Letter of Map Revisions (LOMRs) and how the new HEC-RAS 5 RAS Mapper tools. Recent versions of HEC-RAS 5 have made substantial improvements to the RAS Mapper tool. Many of the features in RAS Mapper can greatly improve the accuracy and efficiency of modeling floodplains for Letter of Map Revisions (LOMRs). This webinar will address some of the modeling requirements for LOMR submittals and demonstrate how RAS Mapper can be a valuable tool in developing LOMR models.
Topic: LOMR and HEC-RAS 5 RAS Mapper tool
Presenters: Brian S. Chaille, P.E. CFM and Chris Hanstad, P.E., CFM (ISWS)
1 PDH/CEC will be offered to those who attend
