[HEC HMS #4]COMPLETE PROJECT IN HEC HMS OF SIMULATION AND OPTIMIZATION

This video shows complete simulation and optimization in HEC HMS for beginners step by step. First process is completed in ARCGIS USING HEC GEO HMS and ARC HYDRO TOOL. Then it is imported in HEC HMS.

While running model, you may encounter multiple errors. Some error occurred in this video also. So you will learn also to eliminate them.

Importing and feeding rainfall input is shown in previous video and this is the continuation of previous video as follow:

Following are shown in this video:
-input discharge data in discharge gage
-Meteorological method includes:
Evapotranspiration
-loss method is used
-Base flow of recession is used
-Muskingum is used for routing in reach/stream routing
-Clark method is used for catchment routing

Finally the model is simulated.

Results obtained:
-Hydrograph at each reach, junction, subbasin
-Calculation table at each reach, junction, subbasin
-Summary table at each reach, junction, subbasin
These can be viewed in the "Result" tab.

Then the model is optimized.
For optimization, certain parameters are given along with their maximum, minimum value, step, iteration number

To create new optimization, you don't need to add all parameters from beginning. Instead you can copy the previous optimization and make necessary changes.

That will be run which is selected in "Compute" tab.
If you select "RUN 1" in compute tab, "RUN 1" will be run.

Optimization gives graph, calculation table, summary table at each junction, subbasin, reach and optimized parameters. All these can be viewed in the "Result" tab.

Hi how did you determine your time of concentration, impervious rate, constant rate, Muskingnum K and X values and all the parameter values for loss, transform method ?

[PADALACHANNEL]

Thanks. In Loss method how you got deficit and constant values

Hello,
I have a problem using the optimization Trial. When I put the dates and hour in the Optimization trial window, it just disapper when I do the next step... I can't put dates and hour and get them saved there using the opt trial.. I don't know why it does that. Do you have an explanation or solution for me please ?

i want to calibrate the HEC HMS result the observed become excess more than simulation. how i can make approximate similar

[ibnuahmed]

how you calculate grid region and why it needs

[vijaysuryawanshi]

hello., how to get Runoff Depth from the model???

[usgsalcsarmiento]

Pero sería interesante descargar mas los datos de estaciones y como se procesan

[Kush.]

hello bro namaste.. i have a question.
How did u input the values in the beginning
I am finding it difficlt to do so for my study area.. please help
I would be greatful

[gopaladya]

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

[manawilab]

From where did you bring the back ground map? how to bring or create background map for our catchment ???

[micaelahernandez]

Hi! I need help with the evapotranspiration values, I calculate them for my example but can I visualise a graph or something like that? thanks

[yassiralawi]

is it possible to simulate without observed data ?

[endaleabebe]

how to procede validation in hec_hms

Hello sir. Need help with HEC HMS? How can i contact you?

[shruthihbabu]

Sir, i need help regarding hechms for my mtech thesis. How can i contact you? Can you provide email id?
