3.5.2. Runoff and Sediment Control Measures

Try these first

1. 1.

   What is runoff?

   Hint

   Remember, it's related to rainfall.

2. 2.

   Name one technique for sediment control.

   Hint

   Think about the method that follows land contours.

3. 3.

   What is the primary purpose of contour bunding?

   • To increase runoff
   • To slow water flow
   • To decrease soil fertility

   Hint

   Which option reduces water speed?

4. 4.

   True or False: Gully plugging is not effective in preventing erosion.

   • True
   • False

   Hint

   Think about the function of plugging.

5. 5.

   Create a comprehensive watershed management plan that includes runoff and sediment control measures for a farm located on a steep hillside. Discuss each method's effectiveness.

   Hint

   Think of how each method addresses both runoff and soil stability.

6. 6.

   Evaluate the effectiveness of WEPP and SWAT models in predicting the environmental impact of urban development on existing watersheds.

   Hint

   Consider how these models analyze land management and erosion scenarios.
