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

1 answer

Certainly! Here's how each concept affects water levels and flow in a river:

  1. Multiple Use Irrigation:

    • Effect: Decreases
    • Explanation: Multiple use irrigation often involves the diversion of water from rivers for agricultural use, which can lead to lower water levels in rivers.

  2. Increase in Precipitation:

    • Effect: Increases
    • Explanation: More precipitation typically results in higher water levels in rivers due to runoff and increased tributary flow.

  3. Presence of Dams:

    • Effect: Typically decreases flow but can increase water levels behind the dam.
    • Explanation: Dams can hold back water, which reduces downstream flow; however, they also create reservoirs that increase water levels in the area behind the dam.

  4. Climate Change:

    • Effect: Can both increase or decrease (depends on various factors).
    • Explanation: Climate change can lead to altered precipitation patterns, potentially increasing rainfall in some areas while causing droughts in others, thus affecting water levels and flow variably.

In summary:

  • Multiple Use Irrigation: Decreases
  • Increase in Precipitation: Increases
  • Presence of Dams: Decreases flow (but may increase water levels in reservoirs)
  • Climate Change: Variable (can both increase and decrease)
