Abstract：In order to replace some inefficient empirical test algorithms of engineering designs, this paper presents cat swarm optimization(CSO)is presented to solve the problem of channel cross-section optimization. To meet with other constraints, choosing suitable slope can reduce land occupation and save investment.At the same time,this paper searches the effect of the slope coefficient change on the channel cross-section optimization under the global space based on CSO and has achieved good results.Taking Jiangchuan irrigation area in Heilongjiang Province as example, irrigation channel section is optimized and the design parameters are analyzed. The examples show that this method has the advantages of high efficiency and high precision and so can solve the problem of channel cross-section optimization effectively. The result shows that area of channel sections reduced by 4.2% and the land occupation also reduced. For parameters, objective function is the best when channel slope is 1.5, width of channel bottom is 2.000 0 m and height of channel is 1.500 0 m. And the effects of these parameters on objective function are analyzed.The best goal showed a trend of first increasing and then decreasing along with the increase of channel slope and height of channel,and showed a trend of increasing along with the increase of width of channel bottom.
