Looking mauka (toward the mountains) up the Manoa Valley from the Marine Sciences Building on the University of Hawai'i Manoa Campus. The Manoa Watershed, one of our study areas, is one of three major watersheds that contribute runoff to the Ala Wai Canal. The Manoa Watershed extends from the relatively pristine conservation area in the Ko'olau Range to the urbanized, impacted area around the Ala Wai Canal.

Our research team is studying three areas on the Island of O'ahu. The first area is the Ala Wai Canal (including its watersheds and nearshore Mamala Bay), the second area is Kane'ohe Stream Watershed (the largest of 16 watersheds of Kane'ohe Bay, and the third is the Waimanalo Watershed. These watersheds are highlighted in yellow on the map below.
