We are pleased to announce the release of HEC-RTS 3.0.3, the public version of the CWMS CAVI.

HEC-RTS 3.0.3 does not include any major enhancements from version 3.0.1 or 3.0.0 but it does fix a number of flaws and inconsistencies that our users and developers have found. This update is the result of many months of work by developers and testers, and we are very grateful for their efforts. Even though HEC-RTS does not have major new features, it does come with modeling program updates that do have significant enhancements. Specifically, HEC-RTS 3.0.3 contains:

Model Updates:
  1. HEC-HMS 4.2.1 (Web release version)
  2. HEC-ResSim 3.3.1 (build 117)
  3. HEC-RAS 5.0.3 (Web release version) Note: This version is required and needs admin permission for install
  4. HEC-FIA 3.0.1

RiverWare is not included in this package, but may be obtained from CADSWES.

The modular design should mean that the release of an update to any of these modeling programs will no longer require an update to the HEC-RTS package itself; it will only be necessary to install the new version of the modeling program, along with an updated plug-in, if needed.
