Clouds often come in contact with vegetation (often named fogs) within a certain elevation range on Hawai‘i’s mountains. Propelled by strong winds, cloud droplets are driven onto the stems and leaves of plants where they are deposited. Some of the water that accumulates on the plants in this way drips to the ground, adding additional water over and above the water supplied by rainfall. Prior observations show that the amount of cloud water intercepted by vegetation is substantial, but also quite variable from place to place. It is, therefore, important to create a map for the complex spatial patterns of cloud water interception (CWI) in Hawai‘i. In this project, we propose to create the CWI map at 0.8-km resolution...
Episodic runoff carries suspended sediment to the nearshore, where it blocks light used for photosynthesis, smothers corals, inhibits coral recruitment, and triggers increases in macroalgae. Even small rainfalls create visible plumes over a few hours. Sediment affects coastal user enjoyment by deteriorating both ecosystem quality and visibility. Sources of erosion include unimproved roads, fallow and active agricultural fields, disturbed forests, local development, and streambanks. In this project, USGS used mapping, field experiments and monitoring, and analysis of recent (July 19–20, 2014) and historic rainfall to estimate sources of land-based pollution for watersheds in West Maui, Hawaii. USGS constructed an...

Over the past century, Hawaiʻi has experienced a pronounced decline in precipitation and stream flow and a number of severe droughts. These changes can have wide-reaching implications, affecting the water supply, native vegetation and wildlife, wildfire patterns, and the spread of invasive species. Several climate-related factors are influencing Hawaiˈi’s landscapes and contributing to these changes. These include climate change, climate variability, and drought (referred to collectively as CCVD). Climate variability describes how the climate fluctuates on a yearly basis around average values, while climate change describes patterns of long-term continuous change in the average. While it is understood that CCVD...

The climate impact summaries will be 1 page for each of Guam and CNMI. These reports are called 'Past and Projected Future Climate Impacts to Guam/CNMI'. A poster describes the past and projected future climate impacts to coral reefs in all of the U.S. coral reef jurisdictions (Guam, CNMI, American Samoa, Hawaii, Florida, Puerto Rico and USVI) and the Flower Garden Banks National Marine Sanctuary.
Project researchers are measuring impacts of sea level variability on coastal reefs and communities. Researchers will relate Pacific climate extremes to local impacts, such as coastal flooding, that matter to residents and resource managers inundation by waves. This handout gives a quick overview of the project methods.
Measurements of fog, wind, fog interception, soil moisture, and fog effects on plant water use and plant survival were collected along with these vegetation data to test a model to estimate CWI as a function of fog-water movement and these vegetation characteristics.

In recent years, rising sea levels have threatened critical infrastructure and cultural assets at Puʻuhonua o Hōnaunau National Historical Park thus motivating the park to make adaptive decisions in managing these key resources. To support the development of decision support tools for sea level rise preparedness, the U.S. Geological Survey (USGS) Coastal National Elevation Database (CoNED) Applications Project has created an integrated 1-meter topobathymetric digital elevation model (TBDEM) for Puʻuhonua o Hōnaunau National Historical Park. This dataset was developed in collaboration with the University of Hawaii- Mānoa Sea Level Center, Department of Interior Pacific Island Climate Adaptation Science Center, and...
The outputs of two versions of the Single-Layer Wet Canopy Water Balance model. Parameters include cloud water interception, evaporation of rainwater or fog water from wet canopy (interception evaporation), and canopy water storage.
