Methods for the design of stormwater drainage systems for highways of minimum construction cost are presented. Three problems are examined representing different degrees of optimization. The first is concerned with finding optimal pipe sizes and slopes for fixed layout networks. The second considers the number and position of intermediate manholes as additional variables. The third allows the geometric layout and connectivity to alter by introducing variable position cross-drains. It is shown that dynamic programming provides a comprehensive approach capable of solving all three problems. Details of the solution methods are presented with numerical results. Typically savings in capital costs of 5-15% may be achieved by the use of these methods which form the basis of computer programs for the practical design of highway drainage. (Author/TRRL)
