This document reviews previous work on the design and construction of low height gravity dams. It discusses several past studies on related topics. Researchers have refined criteria for designing earth dams to resist piping and erosion. Construction of dams is needed on rivers carrying large rainwater flows. For the specific context of Lucknow, India, a dam needs to be built on the Gomti River without diverting the flowing water. Previous literature suggests constructing such a dam using geo bags, boulders, piling and earth over a period of 3 to 5 years. The stability and safety of earth dams against issues like overturning, sliding and piping has been explored in depth by other scholars.
