iBeach utilizes web-cameras installed at high vantage points to collect real-time, high-resolution images over time. This visual data is used to model shoreline changes and detect the causes. Hawaii’s coastlines are susceptible to extreme coastal erosion rates; up to 2 feet/year. Statewide, these erosion rates are only expected to increase with sea level rise, and force property owners and coastal managers to make some tough decisions on how to adapt.
