Since 1986, Coastal Frontiers personnel have performed beach profile surveys to quantify changes in shoreline position and beach volume. Much of the work has taken place in Southern California between Santa Barbara and the U.S. - Mexico border where the profiling effort has been repeated on a semi-annual basis to document seasonal changes at the end of the winter and summer wave periods. Surveys also have been undertaken in remote locations that include Alaska and Siberia.

To accurately portray the condition of the beach, continuous data must be obtained from the backshore to the depth of profile closure. Particular challenges arise in the surf zone where both vessels and swimmers must confront breaking waves and acoustic echo sounders are rendered useless by aeration in the water column. Our survey methods typically include enhanced wading techniques and surf-tolerant inflatable vessels to insure data overlap in this critical region.

Typical Survey Objectives

  • Quantify changes in shoreline position and shorezone volume

  • Establish the depth of profile closure

  • Establish baseline conditions prior to initiating beach nourishment or structural stabilization projects

  • Monitor the effectiveness of beach nourishment projects and the impacts of coastal structures

  • Document the impacts of severe storms

  • Assess sedimentation at nearshore habitats

  • Define the landward limit of dredge operations

During the past two decades, Coastal Frontiers has performed more beach and nearshore monitoring programs in Southern California than all other non-governmental organizations combined.
