Establishing a lake level 1

[VanBurenSoilGuy]

What information would I need to gather in creating a rough lake level outlet into a county drain? What chacteristics would I need to know of the lake watershed? I know that the Dept. of Natural Resources and Environment (DNRE) has the final judgement.

I'm not clear what you mean by "creating a lake level outlet to a country drain".

If you're trying to generate an outflow hydrograph for the lake, you may need to do a complete H&H analysis of the watershed. This would also be necessary in order to design an outlet device - if that's what you're asking.

What is an H&H analysis?

 

[psmart]

H&H = Hydrology & Hydraulics.

What are the limitations of the HydroCAD software in regards to watershed size?

 

[psmart]

There are no limits imposed on the size of the watershed by HydroCAD itself. The issue is choosing the correct methodology for the particular project or analysis. The SCS/NRCS method is most commonly used with HydroCAD, and is suitable for watersheds up to many square miles. But you really need to understand the exact objectives of the study, the nature of the watershed, and the applicable regulations and agencies in order to make a determination of the best tools for the job.

I recommend that you hire a hydrologist to perform an analysis for you.

 

[psmart]

I agree with gbam.

Hydrology is not the best thing to meddle with uneducated. Without training and experience you're more likely to get it wrong than right, and when hydrology and hydraulics goes wrong, folks get their pants sued off.

I'm trying to educate myself. Does anyone know of a good book to begin with in the understanding of hydrology?

 

[gbam]

There are a number of good books out there. The two that I use mostly is Hydrology and Floodplain Analysis, Bedient-Huber, and Applied Hydrology, Chow-Maidment-Mays. For a good Water Resource book look for Stormwater Collection Systems Design Handbook, Mays.

Good Luck! Hydrology or Drainage Engineering is one of the more complex sciences. It is a lot of fun, I really enjoy it.

Also download TR-55 and read through that. It's the procedure most site hydrology follows in the US, to generate inflow hydrographs. There's terminology from that particular document that crops up in hydrology discussions and regulations pretty regularly.
