| Abstract | In order to make a design model more practical as a design
tool, special structures have to be incorporated in the design of
drainage systems. Including just the cost of special structures
into the design does not lead to the least cost design of the whole
system. This is because the interactions between special
structures and the system are neglected. In this study, the design
of special structures and their interactions were considered at the
same time in the optimization model. Pumping stations were first
incorporated in the model so as to obtain the optimal number and
positioning of the pumping stations. Secondly, the interactions
between storage volume and design outflow were considered after
incorporating the storm detention basin. Thus, the optimal
positioning of the basin and the optimal balance between storage
and downstream costs could be obtained. The model was successfully
tested on an IBM PC.
The optimization model is based on non-uniform state increment
dynamic programming with four - dimensional state variable using pipe
elevation, pipe diameter, time of flow, and design peak flow as
parameters. |
