In the short term a rainstorm might damage buildings and habitats by causing a river to flood. What positive effect might a rainstorm have in the long term?

In the long term, a rainstorm can replenish groundwater supplies and hydrate ecosystems, promoting plant growth and biodiversity. The water from the storm can also help restore wetlands, which play a crucial role in filtering pollutants and providing habitat for various species. Additionally, the nutrients washed into the soil can enhance agricultural productivity, supporting food systems and local economies.
