Question

Choose an engineering project that involves both hydrology and hydraulics. In one paragraph, analyze ways in which the hydrology influences the hydraulics, and ways hydraulics influences the hydrology.

Answer 1

-> Design of flood drainage system for a city is a project which involves both hydrology and hydraulic studies.

-> We have the data related to flood quantity and it's frequency from hydraulic studies and channel sizes and their alignment depends on hydraulic studies.

-> Hydrology and hydraulic engineering both are inter related. In hydraulic engineering, we use principles of fluid mechanics to problems relating with collection, storage, transport of water. Before beginning of hydraulic project we need hydrology data, for example to determine size of channel to control flood we need information about quantity of water this is estimated using hydrology principles such as rational method.

-> Hydrology is the science dealing with distribution of water on earth. If we construct channels to transport water from rainfall area to other drought area then ground water in rainfall area decreases because of less infiltration in that area similarly the ground water in drought area increases because of channel flow in that region, in that way hydraulics influences the hydrology.
