摘要：

In coastal rivers, the water level is greatly affected by the upstream movement of a tidal wave. The latter creates higher flood stages that enlarge the flood plain areas and increase potential damages. In such rivers, the water level is not solely a function of the flow discharge but rather a joint function of both the discharge and tidal phenomena. The interference of the tidal backwater with the normal flow of the river causes a disruption in the normal stage-discharge relationship. This paper attempts at formulating a linear relation between tidal water level and river flow discharge that can be used for the predictions of water level in coastal rivers and estuaries. Numerical applications were performed on the St. John river (New Brunswick) and the St. Lawrence river (Quebec) in Canada with satisfactory results.
