# CENV6128 Understanding Civil Engineering (Hydraulics)

## Module Overview

This module provides students with an introduction to how key principles of fluid dynamics are applied to solve practical problems in civil and coastal engineering. Understanding this link between physics and engineering will provide students with the ability to perform and critically assess a range of hydraulic computations commonly used in engineering. These include for instance the determination of the pressure of water on submerged solids (e.g. dams, lock gates), the design of pipelines and open-channels. By the end of the module students should also have gained an appreciation of the different types of flows that may occur in natural and engineered systems.

### Aims and Objectives

#### Module Aims

The course ‘Understanding Civil Engineering (Hydraulics)’ is aimed at providing students with a general science degree the necessary background in selected fields of hydraulics that are important for civil and coastal engineers.These fields are in particular: 1. Properties of fluids. 2. Hydrostatic pressure. 3. Basics principles of mass, momentum and energy conservation. 4. Fluids in motion. 5. Flow in pipes. 6. Open Channel flow.
