[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:
• [HEC HMS #3]EXPORT PRO...
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

[@kimmytoure3626]

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 ?

[@ibnuahmed1740]

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

[@ibnuahmed1740]

how you calculate grid region and why it needs

[@Kush.93]

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

[@JustLearnCivil]

1. You can refer the paper published in or near your study area 2. Initially input values within valid range of variable and after few simulation, values of variable start getting adjusted

[@micaelahernandez3235]

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

[@JALAJDARPAN]

You can use Penmen Morteit method

[@vijaysuryawanshi1374]

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

[@usgsalcsarmiento9578]

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

[@JustLearnCivil]

》Los datos se pueden descargar del sitio web de USGS y utilizar los datos climáticos de TRMM de su ubicación Using Google translator - English 》Data can be downloaded from USGS website and use climate data from TRMM of your location

[@manawilab5322]

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

[@JustLearnCivil]

Create Catchment area in GIS software like ArcGis, Qgis, etc. Then save it as shape file and import background image from Menu - View > background maps. This is 4th tutorial. Refer to the third tutorial for importing whole hec hms project from hec geo hms along with the background maps - kzbin.info/www/bejne/oKWrYoyqZq-fhpI For creating background maps along with whole hec hms project in arcgis using hec geo hms refer to second tutorial - kzbin.info/www/bejne/eHO6Z3qrjriEjNE

[@gopaladya3265]

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

[@JustLearnCivil]

check if there's any negative or null or no data or missing data in you precipitation data.

[@manawilab5322]

Plz check your data maybe mistickenly you have negative data!!! just check it and change it to positive or zero and try again

[@yassiralawi9610]

is it possible to simulate without observed data ?

[@JustLearnCivil]

Yes. But you cannot calibrate or validate your result. If you get error with empty observed data then you can put random (dummy) data and you will get simulation result but you won't get efficiency like NSE.

[@nikhilteja91]

Muskingum X lies between 0 and 0.5.

[@JustLearnCivil]

Yes. Here it is just for illustration purpose of the procedure of HEC-HMS.

[@Lakmysharma-ln7my]

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

[@JustLearnCivil]

facebook page/Email available in the about section.

[@Lakmysharma-ln7my]

Okay sir

[@endaleabebe2853]

how to procede validation in hec_hms

[@JustLearnCivil]

During validation, only run the model (without needing to calibrate) and the observed data will be of validation period.

[@shruthihbabu2823]

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

[@rohi7597]

Are you looking for paid service for your Thesis?
