प्रश्न
Briefly answer the following:
How.can deepening of the river bed help in preventing soil erosion?
उत्तर
Riverbed deepening will also lower the groundwater table along a river, causing a drop in the level of water in wells on the floodplain and threatening to dry out local vegetation. The related erosion of riverbanks — the banks of the Colorado below Hoover have in places been scoured back as much as 15 metres in a year — can undermine riverside property and structures such as road embankments and flood control levees.
