Title. Says you are not authorized for this page.

There are multiple ways I guess, if the study site doesn’t have any streamflow gauge I don’t see how can calibration be done accurately because you will be comparing against other models and comparing with them with no ground truth. I guess that’s the engineering judgement.

If it does have a streamflow gauge, let’s say your first run gave you a volume ratio of about 0.4. So your model runoff at that gauge is about half of what was observed. What parameters do you change first to do calibration? I imagine decrease infiltration? Change infiltration methods? Maybe slightly alter manning’s n if timing of the peak is off.

But until when? Like within 10% margin of your calibration target? Does it rest on your engineering judgement? Does your firm or workplace or government policy have any threshold assigned?

But models like hecras doesn’t account for subsurface flow so if your study site has preferential flow pattern in the vadose zone that is not accounted for by the model then I suppose that’s might be a limitation too.

Asking because I have a research idea in mind but want to know how a seasoned engineer would go about doing it. By couple of infiltration rate I meant, less than 5 distributed around a valley of let’s say 200-300km^2 area. So it can only be used for ‘validation’ purpose so to speak. What dataset would you look for? What maximum resolution of data do you think this would be useful?

Hi it seems finding a place in Storrs is hard. I was wondering if I find a place at Willimantic, how reliable are the bus services to Storrs?

Basically the title. I am still looking for a place starting August but can’t find any I like.

I see bunch of posts 5 hours saying they got an email. Checked, didn’t get any. I filed for two shares. Maybe it’s for the better.
