I am using Hec-Hms, how to edit or cut bridge in Dem Data using Hec-Hms?

Very helpful video, but when I run simulation for my project I get an error message (21401) saying there are no elevation bands set for subbasin. Does anyone know why this is happening, or more importantly how I can fix it? There doesn't seem to be anywhere in HMS where I can set elevation bands, as far as I know. My basin model is of course linked to a DEM, shouldn't that be enough?

Hi, how would you recommend to discretize the precipitation in liquid versus solid form, in a basin that has a lower zone where it rains and a higher zone where it snows? I have the model georeferenced with a DEM and all the sub basins have been created with the GIS tools. Thanks! I need to put some kind of function so in the areas that are over 2000m it does not rain in liquid form, or at least asign cero precipitation (i just need to analyse a 24 hour event)

Hi Felipe, thanks for your question. In this instance, can we suggest you reach out to the HEC-HMS Users Facebook group found here facebook.com/groups/hmsusers/ to get assistance with answering your question? Good luck!

area to define streams depends on what? on what basis did u enter 70 sqkm for area to define streams? Is it the basin area? If at all we are taking it as a basin area we are facing this error WARNING 46501: Unprojected coordinate systems are not recommended for the basin model. as river basin huge its area is 2,58,948 sqkm

I had also the same problem. apparently, it is not activated. and according to HEC HMS manual and I quote;"There are other menu options on the GIS menu that are inactive in HEC-HMS version 4.3 and will be turned on in a future version of the software. The HEC-HMS team is adding GIS tools to the program to aid in automated delineation from terrain data and parameter estimation from GIS datasets "

Is it possible use HEC HMS in Australia? How can we use it with ARR2016?
@davidmoret8943 жыл бұрын
Hi AR V, the accepted hydrological software is RORB however I believe you can use Hec Hms or another software if you wish as long as you can comply with the ARR2019 in relation to ensemble method/Montecarlo etc. for the definition of peak flows/storage volumes and the general required results.
