A．地面倾斜方向要有利于组织地表径流，使雨水向排洪沟或排水渠汇集。
B．注意控制地面坡度，使之不至过陡。两面相向的坡地之间，应当设置有汇水的浅沟，沟的底端应与排水干渠和排洪沟连接起来，及时排走雨水。
C．同一坡度的坡面，即使坡度不大，也不要持续太长，对坡面太长的应进行分段设置。坡面不要过于平整，有所起伏，陡缓变化不一，要通过地形的变化来削弱地表径流流速加快的势头，避免径流一冲到底。
D．要通过弯曲变化的谷、涧、浅沟、盘山道等组织起对径流的不断拦截和方向引导， 减缓径流速度，把雨雪水就近排放到地面的排水明渠、排洪沟或雨水管网中。
E．对于直接冲击园林内景点和建筑的坡地径流，要在景点、建筑上方的坡地面边缘设置 截水沟拦截雨水，有组织地将其排放到预定的管渠之中。
