    Hi Chris,

    Thanks for sharing this article and all the news on HEC-RAS 5.0.
    I've recently started to use the beta version and have found a couple of features which look very, very, interesting.

    First, in the levee breach data editor, one can see a 'simplified physical' tab. At the moment the tab can't be open. Do you know if they have planned to implement this 'simplified physical' breach in the final release ?

    Then, an uncertainty analysis (through monte carlo method) seems to be under development. It can be seen in the run tab of the main window. Unfortunatly I couldn't manage to run this.
    Of course, uncertainty analysis can be done using the HECRAScontroller, but an integrated module would be much appreciated. Do you know more about this ?

    Yes, both of these are likely things they will be adding soon. Hopefully for the final release. Cross your fingers!

    Has anyone tried this new version on Windows 10?

    I haven't, but I have heard of others having some difficulties with Windows 10 and RAS. HEC is not testing HEC-RAS 5.0 with Windows 10, so proceed at your own risk!

    I trying to export a map layer result from rasmapper to google maps. It does create a small file (5kb) named image.db. Still I am not able to work with it….could you shed some light on it..?

    Thank you..best regards

    By the way…I´ve opened the image.db in a dbbrowser and realized that there is no data embedded, just the columns…

    Bruno- there's a bug with that feature. HEC has fixed it, but you'll have to wait for the official release to use it.

    Hello!! Even with this issue is it necessary to write time sliced steps (in optional hdf output parameters) in order to export rasmapper results to googlemaps?

    TKS! Best regards

    No, that shouldn't be necessary.
