Beach elevations at Ninilchik, AK were sampled in field surveys in October 2013 and August 2014 in order to evaluate patterns of profile change over time. Comparison of profile data showed a decrease in bed material, with a calculated annual net erosion rate of 11,664 cubic meters per year, supporting the notion that the seasonal loss of nearshore bed material is contributing to increasingly severe storm erosion.

520 $a Beach elevations at Ninilchik, AK were sampled in field surveys in October 2013 and August 2014 in order to evaluate patterns of profile change over time. Comparison of profile data showed a decrease in bed material, with a calculated annual net erosion rate of 11,664 cubic meters per year, supporting the notion that the seasonal loss of nearshore bed material is contributing to increasingly severe storm erosion.
520 $a Numerical modeling of coastal bed level change was performed to provide insight into the typical response of the Ninilchik beach to storm conditions, and to evaluate design alternatives. The XBeach numerical model was selected for its ability to accurately model hydrodynamic and morphological processes across a two-dimensional domain. A technique for simulating impacts of coastal structures through modification of input bathymetry is introduced. Preliminary XBeach modeling of idealized conditions demonstrated good agreement with the one-line concept of longshore transport response to shore-perpendicular structures. Multiple configurations of shore protection design alternatives were simulated and compared in XBeach, and a series of shore-perpendicular jetties is recommended.
