- the Mawei Harbor is located at the Minjiang tstuary. Owing to the severe silt deposition, the water depth decreased from 8.2 to 1.5 m in the past few years. During 1980-1981, hydraulic model studies had been performed to seek for effective measures to improve this trouble situation. Ten alternative designs were studied in model and the project of a submerged dyke accompanied with groin (Fig. 4) was finally adopted. According to the results of model study, the regulating works were constructed and completed in May 1982. Prototype observation shows that the regulating measures are very successful. Now the water depth has increased from 1.5 to 9.5 m.
