EV-84-14  aA thesis submitted in partial fulfillment of the requirements for the degree of Master of Engineering, School of Environment, Resources and Development  aThesis (M.Eng.) - Asian Institute of Technology, 1984  aThis study describes the development of a computer model capable of determining the diameter, slope and crown (or invert ) elevations of each sewer in a storm drainage system in which the layout, manhole locations, catchment areas, runoff coefficients and inlet time are predetermined. The criterion for  design decisions is the generation or a least-cost system. The basis for the model is the application of non-uniform increment state dynamic programming as the optimization tool. Two examples  of storm sewer system are used as a basis t or illustrating  different aspects of the least-cost design and developing the  pipe subsystem only and pipe , open channel combined system. 0aStorm sewers1 aOrth, Hermann M., eChairperson1 aI, Fude, eExamination Committee1 aOudheusden, Dirk L.
