Brightly colored sand may soon be sprinkled on San Diego County beaches as part of a tracer study to track erosion patterns along the coastline. The study, recommended by a sediment management task force, aims to provide a better understanding of sand movement in the region, challenging the traditional belief that sediment always migrates from north to south. The goal is to gather information that can inform beach nourishment programs and other measures to combat shrinking beaches.
Scientists, engineers, and environmentalists have come together to conduct the study, which involves placing colored material on the beach to track current movement over time. Tracer studies have been used worldwide to study coastal erosion, and the hope is that the data collected from this study will lead to more effective shoreline preservation strategies.
One such pilot project is already in progress in Oceanside, where efforts to replenish and retain sand on the beach are showing promise. The success of this project could pave the way for similar initiatives in other coastal cities and help address the pressing issue of beach erosion in San Diego County.
