在山溪性河道中施测洪水流量,往往受到不少的限制,如溜急浪大,流速每秒达八公尺左右,船只不能施测。为了使汛期测洪水工作提高一步,我们曾利用了湾道投放浮标的方法(如图)。投放时最好在上游凸岸处放一个浮标后,向下游走动数公尺(视水流情况)再放,依此沿岸投放均匀为主。因为湾道凸岸处是顶溜或顺直溜,所放之浮标随着溜势趋向凹处,浮标冲到断面时,如地势较好投放的位置合宜,浮标的
Measuring the flow of water in a mountain stream is often subject to many restrictions, such as large slip surges and a velocity of about eight meters a second, which can not be measured by the ship. In order to take a step forward in flood testing, we have used the Bay Lane buoy method (pictured). It is best to put a buoy at the upstream embankment when it is put on, and then move it several meters downstream (depending on the water flow situation) and then put it evenly along the shore. Because the bay road is at the top slide or smooth slip, put the buoy as the tendency to the recess, buoy rushed to the cross section, such as the location of a better location, buoy’s
