$)$ Briefly explain about the direct step method and the standard step method for the determination of the gradually varied flow profiles.

$2)$ Explain about the step method of integrating the varied flow equations for the channel section.

Hydraulics plays a pivotal role in civil engineering. It enables the design and operation of crucial infrastructure such as dams, bridges, canals, and water supply networks. Assume that you have been selected as trainee in one of the leading water resource management firm, wherein you got the opportunity to work in one of the remarkable projects involving the construction of channels, and installation of the pumps and motors for the hydraulic structures, and at the end of the training, the team lead has assigned you specific tasks related to the hydraulic structures construction, which needs to be completed in the specific period of time.
