Learning Outcomes On completion of this module the learner will/should be able to 1. Create a specification for, and evaluate the findings of, a site investigation. 2. Appraise the suitability of materials and construction methods used in earthworks. 3. Identify potential geotechnical engineering issues associated with road embankments. 4. Define, quantify and formulate the hydrological cycle, surface runoff, infiltration and rainfall/runoff correlation. 5. Carry out hydrological analysis using various techniques, predict maximum flood runoffs and design flows for natural channels, pipes and culverts. 6. Appraise concepts of Sustainable Urban Drainage and apply to worked examples of source and site drainage controls. 7. Critically evaluate concepts of groundwater flow, aquifers and groundwater contamination. Teaching and Learning Strategies This module will be delivered using online lectures and workshops. Assessment Strategies The geotechnical engineering aspects of this module will be assessed using continuous assessment exercis drainage systems aspects shall be assessed using projects and final written examination. The geotechnical of this module are assessed using both individual and group continuous assessment/projects. All students w Assessment Charter at the start of the module which will clearly set out the role of the student, their respons and the project group and the responsibility of other group members to support each other. The sizing the sl assessment (Clelford & Hopkins, 20014) will be used to allocate marks to the individual members of the proj this method of allocating marks will be given to the students at the start of the module.
