Module overview

The safety and sustainability of environmental systems, as well as of man-made structures in the environment, are controlled by a large number of interacting factors. Air and water exert particular stresses on these systems, and so it is important to understand the principles that govern the interaction between elements in order to be able to maintain the integrity of these systems. This module will introduce these principles under three headings.


This topic deals with free surface (or open channel) flows such as those occurring in rivers, canals, lakes estuaries and seas. It also covers flows in man-made structures of different designs such as reservoirs, dams and weirs. Structural integrity of these structures and flooding are 2 key issues, hence it is important to understand the flow mechanisms associated with these free surface flows. The lectures provide a comprehensive overview of the flow characteristics in open channels, the necessary skills to calculate channel profiles and familiarisation with some important hydraulic structures.  These principles will be reinforced by practical applications in the laboratory.


Knowledge of wind engineering is essential for estimating its effect on stationary (buildings and structures) and moving (road vehicles, rail and pedestrian comfort) objects. This part of the module introduces the basic concept of wind engineering. It enables students to understand wind characteristics, flow and turbulence in an external environment and apply this knowledge to determine wind loads on real objects.


The main purpose of water treatment is to protect human health and prevent environmental degradation: this topic will begin by reinforcing this principle. Subsequent lectures will cover the basic concepts in biology, microbiology and chemistry that are necessary to understand the processes that take place during drinking-water and wastewater treatment. The topic will be concluded with a discussion of the natural processes that lead to the removal and dispersal of contaminants in surface and groundwater systems and the methods that are available for monitoring their presence in water.

Methods of Teaching / Learning

This module provides students with a basic theoretical and practical understanding of open channel flow, wind engineering and water quality assessment.

The module is delivered principally by lectures and tutorials, but also includes laboratory classes in open channel flow.

The learning and teaching methods include (hours are indicative):

33 hours lectures
22 hours examples classes
6 hours labs
87 hours independent learning  (guided reading, coursework assignment, independent reading, revision)

Assessment Strategy

The assessment strategy is designed to provide students with the opportunity to demonstrate:

Explain of the theoretical and practical aspects of the different types of channel profiles, and the flow mechanisms and flow characteristics associated with free surface flows.
Demonstrate practical skills in two key principles of open channel flow (for example, wiers and hydraulic jump)

Identify wind characteristics and their effects on structures, forces and moments.
Explain the basic concepts in public health, microbiology and chemistry that are necessary to understand the processes that take place during water pollution, drinking-water and wastewater treatment.

Thus, the summative assessment for this module consists of:

Examination [Learning outcomes assessed:1,2,3,4,5,6,7,8,9,10 (b,c,f,g,h)] (2 hours,60%)
Coursework  - Environmental Quality/ wind forces [Learning outcomes assessed: 5,6,7,8,9,10 (a,b,c,d,e,f,g,h)] (30 hours, 20%}
Free Surface Hydraulics: Laboratory work [Learning outcomes assessed:1,2,4 (b,c,d,e)) (15 hours, 10%); and coursework assignment [Learning outcomes assessed:1,2,3,4 (a,b,e,f,g,h)) (15 hours, 10%)

Formative assessment and feedback

Formative assessment will be through a range of self-assessment exercises provided on SurreyLearn.  Where appropriate these exercises will provide automatic feedback; otherwise feedback will be given in the tutorial sessions. Students will receive written feedback on the laboratory work.
