STUDY ON TIDAL WAVES OF THE QIANTANGJIANG RIVER

In this paper, the characteristic difference schemes are adopted and the proof calculation of actual measurement data of the Qiantangjiang River is made.The calculating result is in agreement with actual measurement data and conforms with the requirements of the engineering (see Table 1, Table 2 and Fig.2).
In the end, the hydraulics model Eq. (16) is discussed and the discussion shows that the characteristic difference schemes (21) can be used to calculate the tidal bore (discontinuity solutions) because the schemes have a pesudo-viscous term (see Theorem Ⅰ.)
