BabaBlast [244]

Answer:

<u>EFFECTS: ( doughts)</u>

  1. There would be less water in the river for you and other people who live along the river to use.
  2. If we use too much water during times of normal rainfall, we might not have enough water when a drought happens.

<u>EFFECTS:( FLOODS)</u>

  2. power plants, roads and bridges are damaged and disrupted, some economic activities may come to a standstill, people are forced to leave their homes and normal life is disrupted.

How to prevent from flooding is :

  1. Construct buildings above flood levels.
  2. Tackle climate change

How to prevent from droughts :

  1. drought trends that may occur based on statistical and actual weather forecasts.
  2. In the U.S., the U.S. Drought Monitor provides a day-by-day visual of the drought conditions around the country.

* Hopefully this helps:) Mark me the brainliest:)!!!
