Abstract:
1. A method of floods control and flood discharge comprising the steps of: (a) setting up a programmable tidal current control gate (PTCCG) at an estuary of a river, wherein said PTCCG, which is built across a river, is selectively controlled between a closed position and an opened position; (b) providing a floods receiving lake; (c) closing said PTCCG when there is a danger of floods in flood seasons for preventing a tidal current from entering into an inner portion of said river; (d) guiding flood water to said floods receiving lake when said PTCCG is closed; (e) re-opening said PTCCG for discharging said flood water into the sea; and (f) keeping said PTCCG opened when it is not in use.
