2. Trapezoidal Channel Problem

Try these first

1. 1.

   What is the formula for calculating the hydraulic radius?

   Hint

   Think about how area relates to the shape.

2. 2.

   How do we define a trapezoidal channel?

   Hint

   Look for the defining features of trapezoids!

3. 3.

   What is the primary equation used in this section for hydraulic flow calculations?

   • Bernoulli's Equation
   • Continuity Equation
   • Manning's Equation

   Hint

   Recollect the equation overview discussed.

4. 4.

   True or False: The hydraulic radius increases as the wetted perimeter increases.

   • True
   • False

   Hint

   Think about the definitions of both terms.

5. 5.

   Determine the effect of changing the bottom width of a trapezoidal channel on the required bottom slope for a constant discharge. Formulate an explanation.

   Hint

   Link parameters to changes in hydraulic radius.

6. 6.

   Propose a design for a trapezoidal channel aimed at minimizing erosion during heavy rainstorms. Describe key considerations.

   Hint

   Consider how landscape architecture can aid in hydraulic functions.
