Sediment Movement on the Continental Shelf near Washington and Oregon.
The nuclides zinc-65 and cobalt-60 associated with river-borne particulate matter are incorporated in sediment on the Continental Shelf near the Colum- ia River. Changes in the relative concentrations of zinc-65 and cobalt-60 and in the ratio of the activity of zinc-65 and cobalt-60 suggest that radioactive sediment moves northward 12 to 30 kilometers per year along the shelf and 2.5 to 10 kilo...
متن کاملThree-Dimensional Model for the Formation of Longshore Sand Structures on the Continental Shelf
i ii Abstract A model is proposed for the formation and evolution of three-dimensional sedimen-tary structures such as longshore sand ridges on the continental shelf in water deeper than that of the shoaling region. Owing to the striking similarity between the bar spacing and the length scales in which interactions among the most energetic modes of shallow water waves take place, we argue that ...
متن کاملLongshore Sediment Transport Rate Measured by Short-term Impoundment
The total longshore sediment transport rate in the surf zone was measured at a temporary groin installed at Indian Rocks Beach, west central Florida. Approximate mass balance between updrift accumulation and downdrift erosion, which served as an indicator of reliability, was obtained in four of the six runs, which were subjected to further analysis. Magnitudes of three of the four transport rat...
متن کاملInfluence of Grain Size on Sediment Transport Rates with Emphasis on the Total Longshore Rate
This Coastal and Hydraulic Engineering Technical Note (CHETN) summarizes the state of understanding of the influence of grain size on surf zone sediment transport and is a companion to Smith et al. (2004). This CHETN discusses details of bed-load and suspended load transport, and the classical bed-load regime is shown to encompass two distinct modes of transport. Four LST models with varying le...
متن کاملReference Concentration for Shelf Sediment Transport Models
My long-term goals are to advance understanding of sediment transport processes. In this context, the long-term goal of this project is to advance understanding of the reference concentration, i.e. concentration of suspended sediments at a small distance above the seafloor. The scientific interest is in relating this reference concentration to the forcing conditions of waves and currents. The n...
