CEIE 340: HEC HMS Hydrologic Modeling

[@hydrowater7965]

What a nice explanation. Thumbs up for setting up the model and looking at different results. Can you please also make a video on how do we compute different parameters (slope, CN, Infiltration) in GIS? how about lag time, K & X ? . really look forward to hear something on that.

[@StMaanco]

Video on this would be great.

[@wajahatannayat9125]

Thank you so much sir, it was really helpful...........need more videos on Hec Hms.

[@mulugetateferi6655]

Thank you very much!!! It is up to date and excellent video, may God bless your mind,

[@skylarjenny2988]

Good lecture.

[@AHGoode]

Enjoyed it. Next time show us how to design/size the Pond for the Walmart. Gig'em!

[@MrAchintha]

Thank You Sir !

[@ganadeepansubramaniam2575]

Should we find the CN separately for each sub basin? Or is the CN is a common value for all sub-basin?

[@choudharipp]

Excellent lecture. please upload such type of lecture on youtube

[@rustanjayceeflores5841]

nice video..can i just ask sir how did you get the value of muskingum x and why did you put 1hr in K.. thank you for your help

[@namwade6742]

sir, can we use daily rainfall data as a time interval for calibration and validation of model

[@firstbrokenstring4997]

There are different hms processes for canopy, surface, loss, transform, baseflow and routing. Could you please make a video of explaining applicability of each process. Thank you!

[@rayralota2368]

Good lecture! Pls make a full lecture about this!

[@adnanmirza4715]

Can you also make a video lec about how to add Reservoir and its properties?

[@akashgaur20]

Informative. :)

[@harshupadhyay3207]

Hi... Thank you for this lecture really! I wanted to ask how is hec hms different from hec geohms

[@jeremyschwartz4974]

thank you for posting this video! Excellent for beginners learning HEC HMS. One question, why did you use a CN of 20? That seems very low, even for soil type A. None of the SCS tables have a CN that low. However, when comparing modeling results to FEMA and USGS data, a CN=20 results in flows similar to that of FEMA and USGS. When using a CN of 60-70 for soil type C, the resulting flows from HEC HMS are about 4 or 5 times that of FEMA or USGS, which seems unrealistic. Have you had any experience with this situation?

[@wilmarhernan8210]

Hi , I have a question Does the number of subbasin has any impact on HMS model? Which is the suitable subbasin number for a basin of 1000 sqkm?

[@michaelmaina5885]

thank you for the very informative video. I am planning on using hysim cc model and i couldn't get any training videos on KZbin. Any leads where i can get one? thank you

Water is not coming from Subbasin-1 to the outlet while doing the same procedure, Why??

[@williamspencer1268]

Great lecture!

[@bowenliu807]

Remarkable lecture! Great intro for novices. Just have one question: I changed the Length, Slope and Roughness dramatically in the Kinematic Wave Transform Input, but the differences shown in the results are minimal. How come? Thanks.

i know im asking the wrong place but does anybody know a method to log back into an instagram account..? I was stupid lost my password. I would love any assistance you can give me.

@Angelo Hank instablaster =)

[@angelohank6829]

@Ahmed Ryan Thanks for your reply. I found the site through google and im in the hacking process atm. Seems to take a while so I will reply here later with my results.

[@angelohank6829]

@Ahmed Ryan It did the trick and I actually got access to my account again. I am so happy:D Thanks so much, you saved my account :D

[@ahmedryan5528]

@Angelo Hank Happy to help :)

[@rociomarrroquin]

What is error 10176? It says: "Can't create default output DDS file"

[@Rinapal3265]

Why my precipitation always error, hec hms said my precipitation is negative, can anyone help me?

[@manawilab5322]

Brother, CHeck you precipitation one by one I think you have just copied from excell sheet. you better know the person he entry the daily or houry data some times they put nagitive mark one case second case, you should check every method you use and when you put data do the run quickly after intering the data if you let your HEC Hms for some hours or you make sleep your computer the program some kind of ignores your input data . there are lots of other factors but first recheck your rainfall. copy it in another sheet changes colors to know any signs or you can retype the data manual if its not long data tnx
