Building upon a companion paper, the present paper addresses additional mechanisms of the tidal bore, including channel taper and friction; building, maximum height, variation, and dissipation of the bore; and standing waves. Early studies of these mechanisms are cited and discussed in historical context. Relationships developed to investigate the effects of horizontal channel taper, vertical channel taper, and channel friction agree qualitatively with and explain field observations. Building of the bore is explained, with favorable comparison of methodology with flume observations. The maximum height that the bore is capable of achieving is one of its most interesting features; this is explained in terms agreeing with experimental observation. The two forms of the jump, undular and wall-like, are discussed. The variation of the bore height as it moves into regions of greater or lesser depth is described from field observations and flume observation, and relationships derived which explain such variation. Frictional dissipation of the bore is discussed. Standing waves that occur after the tidal bore has passed are explained as a separate phenomenon.
