HYDRAULICS AND ENVIRONMENTAL QUALITY - 2022/3
Module code: ENG2101
The safety and sustainability of environmental systems, as well as of man-made structures in the environment, is controlled by many interacting factors. In particular, water exerts stresses on these systems, and so in order to maintain the integrity of the systems, it is important to understand the principles that govern these stresses and interactions. This module will explore this further.
We start by studying flows in open channels, such as rivers, ditches, flumes and sewers. The lectures provide a comprehensive overview of the flow characteristics in open channels and familiarization with some important hydraulic structures. The tutorials help to develop the necessary skills to perform the flow calculations and model the channel profiles. These principles will be reinforced by practical lab sessions where you can observe the different flows in open channels. The second half of the module looks at water quality, water-borne diseases and water treatment systems. This component of the module is more descriptive and case-study based. It is delivered from an industrial/commercial perspective, hence provides insight into the skills required for employability in the water industry. Here, an understanding open channel flows is essential to make sure that the sewage treatment plants are operating under the right conditions, especially given that the main purpose of water treatment is to protect human health and prevent environmental degradation.
Alongside the two academic components, is the group poster work. Here, you will work together to design posters which link the open channel flow component with the water quality component. The posters examine how large man-made hydraulic structures (for e.g. a reservoir, dam or barrage) are constructed and operate and what subsequent impacts they have on the water quality and the environment. The posters highlight the synergies between infrastructure, fluids and the environment which is essential knowledge for engineers moving forwards, given climate change, extreme events and the drive towards more sustainable engineering solutions.

- Laboratory work: complete a virtual lab with supplied experimental data and submit a report as for a face-to-face lab.
- Group Poster: complete an essay on work relating to the group poster topics.
The assessment strategy is designed to provide students with the opportunity to demonstrate:
- the theoretical and practical aspects of the different types of channel profiles, and the flow mechanisms and flow characteristics associated with free surface flows.
- 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.
- practical skills (including independent report writing) in two key principles of open channel flow (for example, weirs and hydraulic jump).
- group work skills (such as listening, negotiating, sharing ideas, empathy, communicating ) associated with the design of a poster.
Thus, the summative assessment for this module consists of:
- Group Poster [Learning outcomes assessed:3,7]
- Laboratory work [Learning outcomes assessed:1-3]
- Exam [Learning outcomes assessed:1-7
Formative assessment will be provided through
- attendance at the group poster sessions where engagement and progress will be guided and monitored.
- a range of self-assessment tutorial exercises provided on SurreyLearn: where appropriate these exercises will be offered informal feedback in the tutorial sessions.
Students will receive written feedback on the laboratory work and on the group poster work.
- A knowledge of the different types of channel profiles and a comprehensive understanding of the flow mechanisms and flow characteristics associated with free surface flows
- A knowledge of the different hydraulic structures encountered with open channel flows
- Practical laboratory experience associated with hydraulic jumps and weirs and how to conduct experiments safely in a lab.
- A systematic understanding and critical awareness of water chemistry and microbiology as they relate to the processes and products associated with drinking-water and wastewater treatment
- An understanding of how these processes affect the sustainability and safety of environmental systems and structures

Methods of Teaching / Learning
The learning and teaching strategy is designed to provide students with a basic theoretical and practical understanding of open channel flows and environmental water quality assessments. The module is delivered principally by lectures and tutorials, but also includes laboratory classes in open channel flow and the poster design work.
- The laboratory sessions are hands-on practicals in which all the students actively participate in small groups (2-3 students) and gain the skills necessary to carry out experiments with open channel flows e.g. flows over weirs. They also gain digital capability (processing data) and report writing skills from writing the lab reports.
- The tutorials are question and answer sessions allowing students time to reflect on and apply the lecture material and develop problem solving skills.
- The poster design work encompasses both the hydraulics and environmental quality components of the module. Students work together in small groups (5-7 students) and are expected to engage both within and across the different groups to gain a broader understanding of sustainable water-themed engineering solutions. The poster sessions include guided activities to help students develop team work, communication and leadership skills. Each member of the group is “the Team Leader” for a week and submits a progression report for that week. This assignment enables students to be creative, selective and resourceful whilst at the same time developing skills such as resilience and robustness through collaborating with their the group.
- At the end of the module (when permitted, post pandemic) there is a field trip to HR Wallingford, an independent civil engineering and environmental hydraulics organisation. Students get the opportunity to visit this experimental flow research station with 90m wave flumes, a ship simulator and a specialist tsunami simulator. Here students can see the intermediate stage between the hydraulics theory they have just learned and real-life situations. This facility builds and tests scale models both experimentally and through numerical simulations and the students are taken on a guided tour of the site by the technical team who work there.
The learning and teaching methods include (hours are indicative):
- Tutorials and guided poster work
- Laboratory sessions
- Poster presentation
- Independent learning (guided reading, recorded content, coursework assignment, lab reports, independent reading, revision, site visit - when permitted)
Indicated Lecture Hours (which may also include seminars, tutorials, workshops and other contact time) are approximate and may include in-class tests where one or more of these are an assessment on the module. In-class tests are scheduled/organised separately to taught content and will be published on to student personal timetables, where they apply to taken modules, as soon as they are finalised by central administration. This will usually be after the initial publication of the teaching timetable for the relevant semester.

Surrey's Curriculum Framework is committed to developing graduates with strengths in Employability, Digital Capabilities, Global and Cultural Capabilities, Sustainability and Resourcefulness and Resilience. This module is designed to allow students to develop knowledge, skills and capabilities in the following areas:
Resourcefulness & Resilience: Students develop the ability to respond to problem-based tasks and provide viable solutions to open channel flows.¿ They are encouraged to exercise and develop their engineering and judgement to evaluate solutions, identify and correct errors; and build confidence in their problem-solving abilities.
- Students will design and create a poster for their coursework assignment. They will record their engagement/progression and submit their final poster using the virtual learning environment (SurreyLearn).
- Students will learn how to tabulate experimental data and utilise computational tools to analyse data and draw a conclusion on patterns and trends in the data. The learning and teaching content is supported via SurreyLearn and student engagement is further encouraged by utilising the online discussion forums for the different topics
Sustainability: Students learn about a major hydraulic structure and its impact on the environment throughout its life-cycle (design, construction, operation, maintenance, failure, de-commissioning). They compare different designs and construction materials and evaluate the pros and cons as to whether their structure should have been constructed.
Employability: Students are taught the water quality component of this module by an external lecturer in the water industry so it is delivered from an industrial/commercial perspective. From this viewpoint, understanding open channel flows is essential to make sure that the treatment plants are operating under the right conditions. The students experience what the industry requires directly from a professional in the field and thus have a better idea of what to expect from this type of work environment, when looking for their own employment in the future.
