Seepage Analysis and Flow Net Construction

Abstract

Seepage is a critical factor in the stability of structures like dams and cofferdams. Addressing and controlling seepage is essential to prevent erosion, reduce pressure build-up, and maintain the long-term integrity of the structure. This paper simplifies the theory of flow net construction, pore pressure computation and seepage analysis mathematical conceptualization. After analyzing seepage under structures, it is crucial to take prompt and effective action to mitigate risks and ensure the long-term stability and safety of the structure. This involves implementing engineering solutions, regular monitoring, and ongoing maintenance, along with making any necessary structural repairs or adjustments. Regular assessments and communication with relevant authorities and stakeholders are also important throughout the process to ensure that the structure operates safely and efficiently. In conclusion, a maximum seepage permissible limit of 5 litres/day per meter of dam height should be adopted for dams.
