| Abstract/Description or Keywords | The process of scour and fill in rivers is the key link between sediment transport and net morphological change in channels. Scour and fill are the results of sediment transport events, where the level of streamflow controls the magnitude of transport. In specific locations in a channel, differences in the amount of scour and fill over time lead to net change in channel morphology. Effective management of fishery resources within rivers requires an understanding of the relation between stream discharge and scour and fill. The direct link that exists between magnitude of scour depth and the loss of anadromous fish eggs underscores the need to understand and predict scour depths. The degree of impact is determined by a combination of the vertical distribution of fish eggs, which varies by species, and the depth of scour, which may be achieved by a single large-magnitude flood event or by the cumulative effect of numerous events over an entire flood season. The purpose of this paper is to examine depths of scour and fill in coastal streams. The specific aims are: 1) to evaluate whether scour and fill depths can be modelled by a specific mathematical function; 2) to establish relations of stream discharge to depths of scour and fill; and 3) to examine relations of scour depths on a regional basis. Establishment of these relations could aid in decision-making related to fishery and forestry resources, by providing a means to predict depths of scour and fill in specific streams or within defined regions. |
