Stored mechanical energy to mechanical energy
the opening of voltage-gated potassium channels and the closing of sodium activation gates.
Sodium and potassium voltage gated ion channels.
Gates are made from mild steel, because mild steel is relatively easy to change shape of, is rather cheap and quite strong.
There are hard engineering and soft engineering strategies. Hard engineering stratigies include: Flood gates Man-made levees Dams Straightening meanders Spillways Soft engineering stratigies include: Flood warning systems Flood plain zoning Sand bagging Insurance Afforestation
Active transport requires energy; passive transport does not.
Not living in a flood plain is usually sufficient.
They are flood gates for the des plaines river.

The Thames Flood Barrier was ready for use in May 1984.
If you're careful, you'll realize that you always hear of kinetic or potential "energy",but not "power".Potential 'energy' resides in an object or a chemical compound, waiting to bereleased and used. Kinetic 'energy' resides in a moving object on account of itsmotion. Neither of these situations involves 'power'. Power is the rate at whichenergy is moved, used, or converted from one form to another. If potential energyis removed from a physical or chemical bucket where it's been stored, or some ofthe kinetic energy of a moving object is robbed somehow, then the rate at whichthe energy goes somewhere else is power.We go to places where water has a lot of potential energy because of its height,and where the potential energy is about to become kinetic energy as the waterpours over the edge and begins to fall. Then we stick something into the fallingwater that can rob some of that kinetic energy, and we use it to run an electricgenerator. The rate at which we're able to divert kinetic energy from the fallingwater is the hydro power we get.

The dam blocks the path of a river and build a huge volume of water. The more the volume the more becomes the potential energy of the water due to the rising height of water in the dam. The water is then allowed to flow through flood gates on to huge wheels. The potential energy stored now transforms to kinetic energy that shows as the speed of gushing water. The powerful jets of water then rotate the wheel. the wheels in turn are attached to a dynamo system that produce electricity. The dynamo used in this case are large versions of the same dynamo that are used in bicycles. Electricity thus produced is then transmitted through cables using transformers.
