Optimal alignment of channel and wanderings mathematician model

On the basis of a revised model of wanderings mathematician,this paper presents a 2-D dynamic programming model for the optimal alignment of channel with known segment function.The model takes the longitudinal slope of the channel and qualitative alignment scheme of each segment as system variables.The minimum works investment is taken as objective function,and the following factors such as the water levels at the head and end of channel,segment transfer of each alignment are regarded as constrains.There are a better results in the optimal alignment with this method than with the traditional one in the application cases.
