Description

The student will be able to derive and apply solutions from a knowledge of hydraulics, sciences engineering science and mathematics. The student will also design a system or structure to meet the specific needs resulting from the analyses and interpretation of data, and display the ability to identify, formulate, analyse and solve engineering type problems.

### Learning Outcomes

On completion of this module the learner will/should be able to;

1.

Analyse and predict catchment runoff and river design discharges by manipulating hydrographs and the storage equation.

2.

Define, quantify and formulate the concepts of the groundwater flow. Apply principles to solving problems involving water abstraction and groundwater contamination.

3.

Analyse and interpret flow behaviour in open channels, utilise data to design hydraulic structures and river channels and predict subsequent flow behaviour.

4.

Define, quantify and formulate the concepts of wave theory. Apply principles to solving problems involving wave prediction and behaviour.

5.

Design a system or structure to meet the specific needs resulting from the analyses and interpretation of data.

6.

Derive and apply solutions from a knowledge of hydraulics, sciences engineering science and mathematics.

7.

Display the ability to identify, formulate, analyse and solve engineering type problems.

8.

Recognise and advice on any limitations or shortcomings associated with the interpretations of laboratory and field test data.

Indicative Projects

1. Students will be required to carry out a significant project on hydraulic modelling of a river catchment. This will include surveying sections of a river catchment and measuring catchment flow rates for calibration purposes. The student will predict flood returns using the FSU, FSR and FEH methods and use HECRAS flood modelling software to predict catchment reaction flow rates and river levels to future extreme events.
