Internal erosion is a major contributor to failure of embankment dams. Failure can occur
within the embankment, its foundations or at the interface between the embankment and
its foundation. Design considerations for internal erosion requires the provision of effective
filters, in addition to assessing the susceptibility of available construction material and natural foundation material to internal erosion. In this assessment, you will explore laboratory
assessment of internal erosion, the design of an effective filter zone and assess the susceptibility to suffusion in a laboratory setting. This will require your knowledge of seepage through
embankments and its foundations covered in previous coursework and assessments.

Requirements
You are required to work independently and prepare a report that addresses all the questions
set out below. All work towards any component of the report must be conducted solely by
you. The report must be submitted via Blackboard by 12pm Wednesday 20 May 2020,
along with the signed EAIT coversheet which can be accessed here.
Submit a PDF that contains either handwritten responses (ensuring that any handwritten
responses are neat and clearly legible) or a typed document that provides all of the steps
and assumptions made to attain the solution. The PDF file should have the following file
name convention:
{STUDENT_ID}_{FULL_NAME}_Assessment_03_CIVL7225.pdf
In addition, any external document that was required to obtain the solution, such as Excel
spreadsheet, MATLAB scripts/notebooks or Python scripts/notebooks, must also be submitted via Blackboard. Use an appropriate naming convention for these supplementary files.
For example:
{STUDENT_ID}_{FULL_NAME}_Assessment_03_CIVL7225_Q1_EXCEL.xlsx
