This project research has started by the fund of Toyo University under the memorandum between ITS and Toyo University. The research theme was selected under the discussion between the staffs in hydraulic laboratory members of ITS and Toyo University, that was the environmental problem in Lamong River. And the fields' observations in Lamong were started in 1991 and the salt intrusion in the river became the main interests on research works in this research groupe. From 1996, the gtant-in-aid of Monbusho could support this research works in funds and several fields' observation could be done. And the severla paper from the results under this can be sent to the International Congress of APD-IAHR from 1994 to 1996.The several results from this research works are derived as follows :1) The type of salt intrusion in Lamong River is the strongly mixed type, which is very different from the one of Japan. And its type is defined by the parameter, which is calculated from the ratio between the saltwater volume supplied by tide prism and the volume of fresh water supplied from upstream of Lamong River.2) The phenomenon on the variation of water level in fishponds connected to Lamong River is depended on the water discharge in connecting channel between ponds and river. This becomes non-linear relation and the parameters determined on this phenomenon can be derived by the theoretical analysis.3) The salt density in ponds is related to the supplied water from the river and the loss of water by evaporation and leakage from the banks and gate. This phenomenon is also analyzed theoretical as the non-linear response and its result can make to clear the facts, as the density in fishponds becomes large inner part of ponds.

该项目研究是根据 ITS 和东洋大学之间的备忘录，由东洋大学的基金启动的。 ITS水力实验室成员和东洋大学的工作人员经过讨论，选定了研究主题：拉蒙河的环境问题。拉蒙河的实地观测从1991年开始，河流盐分入侵问题成为本课题组研究工作的主要兴趣。从1996年起，文部省的援助资金可以资助这项研究工作，并可以进行多个领域的观察。该研究成果的后续论文可发送至1994年至1996年召开的APD-IAHR国际大会。本研究工作的几个结果如下：1）拉蒙河盐分入侵类型为强混合型，与日本的盐分入侵类型有很大不同。其类型由参数定义，该参数是根据潮汐棱镜供应的咸水量与拉蒙河上游供应的淡水量之比计算得出的。2）与拉蒙河相连的鱼塘水位变化现象取决于池塘与河流连接通道的流量。这就成为非线性关系，通过理论分析可以得出根据这种现象确定的参数。3）池塘中的盐浓度与河流的补给水量以及堤岸和闸门的蒸发和渗漏造成的水损失有关。这种现象也从理论上进行了分析，因为非线性响应及其结果可以使事实变得清晰，因为鱼塘中的密度变得很大。
