Assessment Strategy

The assessment strategy is designed to provide students with the opportunity to demonstrate the depth and breadth of their environmental and hydrological engineering understanding, and their ability to apply it to real problems.

Thus, the summative assessment for this module consists of:

  • Coursework (40%): students are tasked with the design of a water treatment facility. They are allowed to work in groups of up to 3 students.

  • Exam (60%): in-class exam at the end of the semester, which will assess the independent understanding of the environmental and hydrological engineering theory and the ability to apply it, as well as the students’ capacity to demonstrate the depth and breadth of their learning in the critical answers to discussion questions.

Formative assessment and feedback are provided to students during the tutorials and computer lab sessions. The academics have office hours 4 hours per week. Doubts are also answered through a discussion forum on SurreyLearn and via email.

Module aims

  • To provide students with a clear understanding of water quality indicators relevant to drinking water.
  • To train students in the process of treating natural and contaminated water to achieve a potable status.
  • To provide students with a clear understanding of the water balance components, which are the corner stone for addressing water resources sustainability challenges.
  • To provide students with the basic theory and digital capabilities for the analysis and simulation of extreme rainfall events.
  • To develop the students¿ resourcefulness for the location and exploitation of novel environmental data sources.

Methods of Teaching / Learning

  The learning and teaching strategy is designed to provide students with:

  • sound theoretical background on water treatment processes and ability to undertake basic engineering designs of treatment facilities.

  • theoretical basis of high flow hydrology and digital capabilities for its application to engineering flood management challenges.

  • theory of water balance and sustainability, and ability to apply it to real scenarios.

Class notes, captured lectures, tutorials and solutions, and guided learning instructions are provided on weekly basis on Surrey Learn. Students are encouraged to go over the captured content before the face-to-face seminars, tutorials and computer labs.

Captured lectures are illustrated with real case applications of the covered materials, in order to strengthen the student´s ability to link theory and complex real engineering problems.

Theory, tutorials and lab sessions are combined, so students consolidate their theory straight away, with hands-on applications. The academics monitor students during the tutorials and lab sessions, and provide personalized support.




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.

Other information

This module is designed to allow students' development in the following areas:
Digital capabilities: the students learn digital tools for the retrieval of spatiotemporal hydrological measurements and for their transformation into actionable engineering data. This contributes strongly to their employability.
Resourcefulness and Resilience: the students learn to locate and select appropriate hydrological data worldwide for engineering applications. The module provides digital spaces (on-line forum, office and on-line drop-in sessions) to maximize opportunities for direct feedback, and enhance the emotional/affective dimensions of learning.  
Sustainability: the module teaches the underlying concepts of sustainable water resources management and has direct links to Sustainable Development Goal (SDG) 6 on ensuring a clean and stable water supply for all.

ENG3177 culminates the water thread of the civil engineering BEng programme, which consists of modules Fluid Mechanics and Pipe Hydraulics (ENG1073), Hydraulics and Environmental Quality (ENG2101) and Integrated Design 2 (ENG2107).
