Nando; Now,there is no canal and reservoir.This project is at very beginning.So I do not know the distance between the river and the reservoir.I have made a mistake when giving information.The volume of 0,5 m3/s is valid for 8 months for river.I think the flow rate of canal will be lower than 0,5 m3/s and the flow rate of turbine will be lower than the canal flow rate.(Please correct me if I think wrong).I will try to learn the minimum and maximum values of flow of river and will inform to you.
I think the reservoir volume may not be very big.Because the canal will continue to feed the reservoir when turbine emptying the reservoir.If the difference between the flow rates(canal and turbine) is about 50 litre/sec.,it may be sufficient to make the head stable. Nando; I do not understand your suggestion about why I need a reservoir.If I bring the water from directly from the river,I will not be able to regulate the system,because the river will never give the constant flow.Please clarify this subject. Thank you very much for your kind interest.
