Question

list and describe three different flood control strategies including advantages and disadvantages of each one

Answer 1

Trees having strong root systems will be better for planting in those areas having a higher chance of flood to happen. Trees like Mangroves can protest from Tsunami. There are not many disadvantages by afforestation, but planting a big tree near some agricultural lands or several tiny plants will cause water and mineral scarcity for them and they will dry. It requires more time for a tree to grow big enough for persisting these disasters.

Construction of a dam is really expensive and needs approval from different authorities. Any faulty constructions will be a disaster for the entire society.

3.) Diversion canals and rain harvesting are other remedies to control flood. Excess water can be flown through these canals to any other dry places or lake or sea or using Rain harvesting excess amount of water can be stored. Many countries are opting for these methods for solving from flood and water scarcity. But they should be maintained properly. Improper water diversion and harvesting may lead to not get settle down to Earth or water contamination or pollution which will happen to arise various health problems and diseases.
