Hydrologic Modeling using HEC-HMS: Setting up the model (2/9)

This is 2/9 video of the HEC-HMS modeling module. In this video, you will learn the following: (i) Creating a new HEC-HMS project; (ii) Creating an empty basin model in HEC-HMS; (iii) Load terrain data in HEC-HMS and (iv) Define coordinate system in HEC-HMS. The tutorial (with link to data) to go with this video is available at:

Sir, can you please explain how cngrid raster was created? It is not mentioned in the previous module, "Introduction to Hydrologic Modeling using HEC-HMS (1/9)."

Sir, how can i get the data folder. as it is deleted from the link provided in description

Sir please i use this video as a tutorial and i kept getting error when i try to load the terrain data (cedar_dem.tif). after creating the terrain data, it doesn't show on the watershed explorer and when i click on coordinate system under GIS, the coordinate system drop down is empty. what could be the error please?

[@hydrologyvideos8253]

Make sure you set the coordinate system in the basin file. it it still does not show up, save your project, close it and open again.

Good morning sir Thank you very much for all theses videos,they are very interested

Please sir i have the 4.10 version of hec hms,can you tel me if it is possible to calculate the curve number on it?

Hello sir, how can I create DEM Model for Hec-hms? Because it is not mentioned in previous video.

[@hydrologyvideos8253]

there are global DEMs available that you can use for your area of interest. or you can create one if you have survey topography data

[@debuaddhya6319]

Sir, I have follow this video thoroughly, but for some unknown reason the DEM dose not showing in the basin model window. Can you please tell me how I can solve the problem??

[@hydrologyvideos8253]

at 8:20 in the video, I explain what to do if the DEM does not show up. Also you can save your project, close an open again to see if it shows up.

Sir, Can you tell me if hec-hms works only with sentinel tif file as terrain data please ? I use a srtm tif file but it doesn’t appear

[@hydrologyvideos8253]

It should work with any DEM in TIFF format. Make sure the data are projected.

Good day, Sir/Maám! I am a college student taking BS Geodetic Engineering in the Philippines. I am currently taking my thesis load. Can I ask what site or open source can I get the data (for my chosen study area) that I need to be able to perform the hydrologic modeling? Your generous reply is highly appreciated. Thank you!

[@hydrologyvideos8253]

where is your study area? i am not familiar with data availability in your country. You can try global datasets.
