[Introduction]: The purpose of this research project is to use problem based learning to develop an understanding of flow net theory. Flow nets are graphical engineering tools that are used to determine flow of water from one soil medium to an excavated or dry working area (Forchheimer PE, 1902). This research project is being used to demonstrate the concept, critical thinking and analysis required to solve a relatively vague engineering problem....The flow net analysis is a relatively disjointed and incomprehensive engineering tool that is not used extensively in industry. It is the purpose of this project based learning approach to demonstrate the quick and effective way in which flow nets can be used to accurately model the flow of water through soil mediums (Hausmann MR, 1990).

Cofferdams are a widely utilized construction technique used to create a dry, consolidated working area for foundation construction through the displacement of water. In most cases cofferdams can be defined as a working area below water table level, but exhibiting a dry working environment. A flow net is a graphical means of representing the seepage of water from the exterior environment into the cofferdam construction area...This project will aim to provide a comprehensive understanding, analysis and design procedure for the correct evaluation of cofferdams using flow nets. This project will involve extensive literature review, numerical analysis and physical modeling...This project (Hausmann MR, 1990) aims to produce a comprehensive overview of flow nets and their correct application to cofferdam construction.
