Abstract : Engineering design of an earth dam is a crucial issue from the view point of safety and economy of construction cost. Following a scientific approach, it aims at formulating the problem of designing earth dams as an optimization problem. The problem is formulated as a nonlinear program with dam cross sectional area - In general, the most severe construction loading condition is at the end of construction. If the embankment is constructed in stages, however, there may be some intermediate construction stages that require analysis. Based on responses to the questionnaire, this loading condition is not usually considered for very small dams (less than 20 feet
