Question

Dragon drop each concept indicate whether it increases or decreases the water levels and flow in a river each year
multiple use
irrigation
increase in precipitation
presence of dams
climate change

Answer 1

Here’s a breakdown of each concept and how it affects water levels and flow in a river each year:

### Increases Water Levels and Flow
- **Increase in Precipitation**: More rain increases the volume of water in the river, raising water levels and flow.

### Decreases Water Levels and Flow
- **Multiple Use**: This can vary, but typically refers to the withdrawal of water for various uses (agriculture, municipal, etc.), leading to decreased water flow in the river.
- **Irrigation**: Similar to multiple use, irrigation diversions decrease the amount of water flowing back into the river, thus reducing water levels and flow.
- **Presence of Dams**: Dams can trap water, creating reservoirs and thus often reduce downstream flow and can alter natural water levels.
- **Climate Change**: While the effects can vary by region, climate change generally leads to potential increases in evaporation and can alter precipitation patterns, possibly decreasing annual water flow in rivers.

### Summary
- **Increase in Precipitation**: Increases
- **Multiple Use**: Decreases
- **Irrigation**: Decreases
- **Presence of Dams**: Decreases
- **Climate Change**: Generally decreases, depending on local effects.
