In Taiwan area often have typhoon attracting during summer times. Typhoon brings abundant rainfall and the rainfall concentrates to the river, naturally washes out the main channel and the river high alluvion. When flood retreat, the exposed high alluvion can be widely used. Agriculture, plant and wetland, these places can increase zoology. On the other hand ,they baffle current of water flow. So this research focuses on different arrangement of flexible vegetation.

中文摘要因为台湾地区因气候关系常有台风侵袭，台风来临时带来的充沛雨量集中到河川，自然冲刷出主河道和高滩地，当洪水退去时，裸露的高滩地即可以广泛地被利用，有许多的人为开垦、种植，但是这些植生有增加动植物栖地的益处，另一方面也会产生阻碍水流的害处，所以本篇对於不同布置方式的柔性植生做流场的研究。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.
