It is difficult to give you proper advice without fully understanding your plans and design requirements.

Do you have complete control of the aqueduct gate at the top of the channel? Meaning you can regulate the exact flow rate of water by manipulating the gate. Also, you are never forced to open the gate all of the way due to local regulations or to mitigate a flood during a heavy rain event.

Knowing those factors will significantly change your engineering requirements compared to "full open" flow.

Are you just trying to stop erosion down your slope? If so, then limiting the water is the best option.

When you say you want to use your available water resource, is that for a small household, or are you going to irrigate crops over an area of 100 hectares?

If we get some more info, you can probably get some more useful advice.
