Abstract
The Turbidity Plume Model simulates the possiblity of a plume developing at the Ala Wai Canal, Oʻahu. The plume position and turbidity values are determined by the results of the ROMS Ocean Circulation Model configured for Waikīkī with input from SWAN (waves) and WRF (atmosphere). The model also uses near real-time river runoff and turbidity measurements from the Mānoa-Palolo stream that flow into the Ala Wai Canal.
Low turbidity levels (beige) are a result of regular ocean conditions. If however the model shows a dark orange plume, meaning very high levels of turbidity, the results could indicate the fate of large discharges from the Ala Wai due to heavy rains or other events and the generation of a coastal “brown water” plume. Please visit the State of Hawaiʻi Department of Health Clean Water Branch (CWB) for more information on storm water runoff.
