Description'A'ohe hua o ka mai'a i ka lā ho'okahi: is a native Hawaiian saying that means “no task is too big when done together by all”. Pollution is a huge global problem whose solution beckons every individual’s participation every moment of the day. In order to engage and empower an individual, you must first make the problem relative to them. Storytelling narratives have historically been an important way knowledge is passed on in traditional Hawaiian culture. This visualization showcase aims to integrate Hawaiian storytelling traditions and data-science to engage the local population around the Ala Wai Watershed and invite them to take action.

The 2 mile long Ala Wai Canal was designed and artificially created in the 1920’s to drain the area that would become the extremely popular tourist destination, Waikiki beach on the island of O’ahu in Hawaii. The canal runs between the ecologically important Ko’olau Mountain Range down to the densely populated Waikiki beach. Dramatic elevation changes combined with high rainfall poses safety risks due to flash flooding. The Ala Wai canal is also extremely polluted and poses health risks due to disease and chemical exposure.

Efforts to monitor, understand and quantify pollutant loadings into the Ala Wai Canal from various sources are underway. This work will provide an immersive Virtual Reality perspective of the Ala Wai Canal network stations pollutant levels and water flow over an Arc-GIS framework integrated with a Hawaiian storytelling perspective to provide a culturally-informed water map of the Ala Wai area.
