watershed area
Examples
- For catchment areas greater than gutter capacity , slotted holes can be installed
如果汇水面积大于天沟排水能力，可以在天沟底部打孔。 - A drainage area threshold is used to produce a continuous network , so that different network is obtained for varying drainage area threshold
为了得到连续的河网，方法中引入了汇水面积阈值的概念，但对于同一流域，利用不同的汇水面积阈值将得到不同的河网。 - A method is proposed , in which the relation between source density ( or drainage density ) and the threshold is used to produce an ideal drainage network , the area threshold when source density ( or drainage density ) show stability is reasonable
提出了一种方法，利用河源密度(或河网密度)与汇水面积阈值的关系，确定汇水面积阈值，当河源密度(或河网密度)趋于稳定时对应合理的面积阈值。
