Which of the following is/are the preventions of stray current effect in an underground channel? Correct Answer Use of bus conductor and rearrangement of anodes

Stray current effect caused due to the densely buried underground pipelines in the vicinity of the cathodic protection system. It can be prevented by the use of bus conductors and rearrangements of anodes.

The discharge through a trapezoidal channel is 61 m3/s and the depth and widths of the channel are 4m and 5m respectively. The wetted perimeter of the channel is 13.16m, calculate the bed slope of the channel if the value of C is 45.
Calculate the corresponding hydraulic mean depth that would exist in the channel if the bed was unrippled. The rugosity coefficient in an unrippled channel is 0.015 and the rugosity coefficient actually observed by experiments on the rippled bed of channel is 0.020. Consider the value of hydraulic mean depth of the channel as 1.5 m.
