Step 1: The Electric Grid

Step 2: SCADA control

Step 3: Water Transmission
Step 4: My lousy drawing
There is of course a lot not shown or covered here. When you transmit electricity there are losses from resistance in the wire, wire length etc. In Water you would have the same thing including time, the size and capacity of the channel/stream as the water travels so as you pump 2000 gallons you may have to wait to begin removing the 2000 gal based on some set standards for water flow. Also is the size of the pumps, throughput, velocity, etc. In the picture below you would also notice that the flood areas are probably beginning way up river thus to remove the flood water you larger transmission pumps/Channels/and sluices would be on that end and smaller branches and tributaries would distribute to other parts of the country. The smaller branches having smaller capacity thus having small reservoirs or catch basins. Once capacity is met other stations will have to meet the need.
Step 5: The COST
Step 6: Cost of floods
in the United States, the average annual cost of flood damage is more than $2 billion. Each year about 100 people lose their lives to floods.
So if we can control the floods and redistribute the water this would represent the a savings of $2 billion a year and save homes.
Step 7: Cost of Drought
Step 8: COST continued
I will not even estimate because I cant to it justice but an idea comes from http://www.stoneflytech.com/assets/32/Low_Cost_Canal_Automation_and_SCADA.pdf where a low cost system is suggested from the late 1990's and 2000. The cost would be a lot higher today.
The pump systems will cost a lot more. One station costs $500 Million as a part of the Louisiana levee system which is expected to cost $14 Billion when complete.
Not to mention the labor for a US wide plan. This idea could put a lot of people to work and in an economy like today its real difficult to think of spending desperately needed money so the idea I put to you. Is this too ambitious and costly and idea. Could we have a system to distribute water throughout the US. Would such do little to solve the problems we already have or just a drop in the bucket.
