Specifications include, but are not limited to: • Study historical coastline, lagoon configurations, upcoast sediment input to the Malibu coastline littoral cell, and how those have changed over time • Perform a watershed assessment of sources and sinks of various grades of sediment, and bathymetric surveys of the lagoon, inlet, and beach (open and closed berm conditions) • Characterize linkages between the nearshore surf zone, the littoral sediment transport system, and creek, lagoon, and wetlands hydrology/geomorphology • Analyze dynamic material balances for sediment deposition on the sand berm and nearshore, as well as scour at the lagoon shoreline and outlet • Conduct an assessment of littoral sediment deposition to inform modeling of sand berm buildup from coastal processes
