“…Demirbilek et al (2010) describes the analysis performed that ranked the return periods of quarterly events as 1993Q2 (0.5 year), 2006Q4 (2 year), and 1998Q4 (5 year). The extreme storm event from the 38-year record was found to occur during the period 20 January -18 February 1990.…”

“…Near-field modeling of local scale sediment transport affecting the DMP sites: Modeling was performed using the Lagrangian model MPFATE that represents dredged material descent from the placement vessel, collapse of the dredged material on the sediment bed, and passive transport of dredged material in suspension (Demirbilek et al, 2010). MPFATE was used to simulate the accumulated sedimentation resulting from multiple placements of dredged material from hoppers and scows dredges.…”

The US Army Corps of Engineers Seattle District (NWS) is addressing short-to midterm dredge material management strategies for the Federal Navigation Project at Grays Harbor, Washington. This includes evaluating navigation channel realignment in the Point Chehalis/Entrance reach. It is hypothesized that relocating the channel to align with natural channel migration will reduce future annual dredging quantities. However, the most heavily used dredged material placement sites lie in proximity to the Federal navigation channel. Thus, the goal of this numerical modeling study was to assess the impact of the three dispersive dredged material placement sites on future channel maintenance dredging.The modeling study simulated tidal and wave-induced sediment transport in the Grays Harbor estuary using a surface water modeling system EFDC under four different hydrodynamic and wave forcings that corresponded to 0.5-, 2-, and 5-year events and the most extreme event from a 38-year wave hindcast record. A coastal wave model CMS-Wave was used to simulate wave conditions in the model domain, and a regional circulation model ADCIRC was used to provide the clamped tidal boundary conditions along the ocean boundaries of the EFDC model domain. Model results using both the existing and realigned channel configurations were analyzed to estimate residence times of dredged placed sediment at the three placement sites and channel infilling rates from sediment eroded from the placement sites for the existing and realigned channel configurations. The findings from the analysis indicated that there were significant differences in the erosion rates of the dredged material between the existing and realigned channel simulations at one of the three placement sites, and that there were no significant differences in the fate of the eroded sediment between the existing conditions and realigned channel configuration. 560Estuarine and Coastal Modeling (2011) Downloaded from ascelibrary.org by New York University on 08/02/15.
