Effective interpretation of weir foundations is a vital component of design reviews to provide a reliable assessment of safety and performance assessment of these structures for many years to come. This paper explores the methodologies and insights from two design reviews of weir structures constructed along the River Murray in the early 20th Century: Mildura Weir and Torrumbarry Weir, both founded on highly variable riverine floodplain foundations.
These design reviews involved compiling extensive interpretation of the available historical data and using this information to develop a conceptual engineering geological model of the sites to guide the selection of geotechnical parameters for early assessments. No two elements of foundations’ behaviour are the same, and modelling is an equally crucial step to turn the potentially unlimited level of detail of the “real” foundations into practically simplified but workable and realistic geotechnical models. Each site presented unique challenges in foundation interpretation, which significantly influenced the overall findings of the engineering assessments.
This study highlights the importance of sensitivity analyses and the impact of interpretation of historical available data on assessing potential deficiencies and failure modes.
