A model for tides and currents in the English Channel and southern North Sea A model for tides and currents in the English Channel and southern North Sea
The amplitude and phase of 11 tidal constituents for the English Channel and southern North Sea are calculated using a frequency domain, finite element model. The governing equations - the shallow water equations - are modifed such that sea level is calculated using an elliptic equation of the Helmholz type followed by a back-calculation of velocity using the primitive momentum equations

ANALYSIS OF ESTUARINE TRACER-GAS TRANSPORT AND DESORPTION. ANALYSIS OF ESTUARINE TRACER-GAS TRANSPORT AND DESORPTION.
The riverine tracer-gas technique provides a direct, reach-averaged measure of gas exchange, is fairly simple to implement, and is widely accepted for determining reaeration-rate coefficients in rivers. The method, however, is not directly applicable to flows having vertical density gradients. Consequently, studies were undertaken to develop and evaluate methods for obtaining surface...

DEFORESTATION AND LANDSLIDES IN YUNNAN, CHINA. DEFORESTATION AND LANDSLIDES IN YUNNAN, CHINA.
Landslides historically have caused severe erosion problems in the Xiao River drainage region of northeastern Yunnan Province, China, that hence resulted in serious economic and social consequences. Owing to monsoonal storms of high rainfall intensity, the erosion potential is high in this mountainous, seismically active region. Landslides transported large quantities of materials into...

DISCHARGE AND DEPTH BEHIND A PARTIALLY BREACHED DAM. DISCHARGE AND DEPTH BEHIND A PARTIALLY BREACHED DAM.
The role that the velocity-distribution correction factor plays in the determination of the flood discharge and corresponding flow depth behind a partially breached dam is investigated. Assumption of a uniformly progressive flow for an established dam-break flood in a rectangular channel of infinite extent leads to the formulation of a theoretical relation between the depth and velocity...
