HEC-GeoHMS Parameter Estimation

[AliAkel]

Hello,
I'm using HEC-GeoHMS 5.0 on ArcGIS 9.3. After running all the parameter estimation tools, hec-geohms only estimates the parameters for the SCS loss methods, the TR-55 tc and Muskingum-Cunge & Kinematic wave parameters. All the other parameters (Clark TC & R, Muskingum K & X etc...) are left blank. Does HEC-GeoHMS have the ability to automatically estimate these parameters or do I have to calculate them manually and add them to the tables?

Hello,

I have a similar query. Do we have any option in GeoHMS to auto calculate the Muskingum K and X parameters.

Hi,
I have exact question, fields are left blank for me as well.

Thanks

I think there is no option in GeoHMS to autocalculate the parameters except for going with TR-55 method, where the parameters are calculated in the excel sheet.

Other than this, if you have accessiblity to ArcView , you can install CRWR-Prepro tool which is similar to preprocessing tool like
GeoHMS and is supported by HMS too. Here, the parameters are auto calculated.
