This project was carried out to make clear the bank erosion of Saigon River. At first some test fields were set and the SPT, soil sampling and a series of laboratory tests were conducted to clarify the ground profile and the basic mechanical properties of soils at the fields. Then the water level, the distribution of the flow velocities and the cross section shape of the river bed were observed by use of ADCP, a measurement device using ultrasonic wave.Reserch on countermeasure for prevention of river bank erosion was also carried out. Firstly some conditions to make good improved soil were investigated by using common materials in Vietnam. Next some numerical simulations were conducted to investigate the effective reinforcement countermeasure. The Japan/Vietnam joint-seminars were held four times to share the above reserch results each other.

该项目的实施是为了明确西贡河的河岸侵蚀。首先设置试验场，进行标准贯入试验、土壤取样和一系列室内试验，以弄清试验场的地面剖面和土壤的基本力学性质。利用超声波测量装置ADCP观测了该河段的水位、流速分布及河床断面形态，并对防治河岸冲刷的对策进行了研究。首先，利用越南常用的改良材料，对改良土壤的条件进行了研究。其次，进行了数值模拟，以探讨有效的加固对策。日本和越南联合举办了四次研讨会，相互分享上述研究成果。
