Dam/Reservoirs in SWAT modelling

[majid...@gmail.com]

Hi everyone,

I have a watershed that I am trying to model the surface runoff for it, and I want to model the runoff for different land use maps of different years. In my watershed I have 2 dams, and I only have certain information for both dams, and I am not able to obtain other information for the dam operation. I have year the dams started operation, I have dam capacity, surface area, dam height, crest length, and I also have the amount of water each dams supplies to water treatment plants down stream. However I am not able to get dam discharge/release rates. And my gauging station is down stream below the dams.

So I wanted to know is there anyway I can still calibrate my SWAT model with the information I have? or any other method or software I can use to simulate the surface runoff, with the information I have?

I will really appreciate any help and advise, as I am currently stuck with this issue.

Thank You All,

Majid.

Hello,

That is way more information on the dams than usual :) So you are lucky and of-course you can calibrate the model with that info.

There was a discussion on calibrating dams/reservoirs in this group or the swat-user group. Jim explained everything quite well there, with suggested parameters (IRESCO, NDTARG, etc.). I remember that advice helped me alot :)

Try to use the search option and find discussions on reservoirs/dams, I'm sure you will find your answer!

Cheers,

Natalja
