Answer:
A flood is an overflow of water that submerges land that is usually dry.[1] In the sense of "flowing water", the word may also be applied to the inflow of the tide. Floods are an area of study of the discipline hydrology and are of significant concern in agriculture, civil engineering and public health. Human changes to the environment often increase the intensity and frequency of flooding, for example land use changes such as deforestation and removal of wetlands, changes in waterway course such as with levees, and larger environmental issues such as climate change and sea level rise.
Answer:
Things get dry. In the short term, plants that have short root systems will dry up and may go dormant or even die, depending on their drought tolerance. Some plants will have deeper roots that can reach down into shallow ground water reserves. In the long term, those ground water reserves will not be replenished if the rains do not fall and will start to recede. The deep ground water often comes from rains that fell in highlands centuries and millennia ago and slowly moved through the ground to us. So if the rains never come for that time length even these will eventually dry up. All plants will die, except the few we might be able to irrigate using expensive desalinated water. Hopefully some long-term thinking will have allowed us to put off short term profit and spend the money to create those desalination facilities. Otherwise, if the short-term profit motive wins, we all die. Even then, we may not be able to replace the oxygen we consume because it’s the green plants that produce the oxygen for us.
