How to Prevent and Fight Floods

Okay, great job on identifying unsustainable logging as a cause of flooding, but you missed one massive cause/prevention of increased flooding. Soil organic matter levels have been decreasing all over the world, under cropland, residential property and in many forests. An increase of 5% soil organic matter can lead to approximately 7% more water retention capacity and can hold that water for 1-4 more days after rainfall. The two major problems with river flooding are the speed with which the water flows off the land and the last several gallons that push the river over its banks. Increased organic matter levels can solve both of those problems. Basically, you turn the land into a sponge that can hold massive quantities of water for days at a time.

Two other side benefits from increased soil organic matter are improved plant growth and decreased atmospheric CO2 levels. But those are topics for another time.
