甘竹溪是西江下游的一条支流,它的上游入西江口处就是甘竹滩。滩口窄而流量大,过滩水势如万马奔腾,浪涛汹湧,最高时出现1米多高的落差。加以甘竹滩地处潮感区,其水文情况既受到西、北江洪水影响,同时又受到潮汐的影响。致使甘竹滩的潮汐情况形成为:滩上涨潮慢退潮也慢;滩下涨潮快而退潮也快。 Gan Zhuxi is a tributary of the lower reaches of the Xijiang River, its upstream into the Xijiangkou is Gan Bamboo Beach. Narrow beach and large flow, cross the beach water potential such as thousands of horses Pentium, rough waves, the highest appeared when the height of more than 1 meter gap. To Ganzhu Beach is located in the tide area, the hydrological conditions are not only affected by the West and North River floods, but also by the impact of tides. As a result, the tidal conditions of Ganzhu Beach are formed as follows: the tide of the tidal flat on the beach is also slow; the ebb tide of the beach is fast and the ebb tide is also fast.
