Flood control projects often spare land but increase the prospects of flooding downstream because upstream flooding provides a buffer. Stream velocities may increase without flooding scouring the stream beds.<br><b>References : </b><br> Areas of land are divided into drainage basins (large and small) separated by divides (high points along ridges) that drain rain and snow melt to a lake or the sea, etc. Anything dumped into the drainage basin may find its way to the creak (or river) through surface runoff or movement of groundwater (especially near dumps, etc.).
