Joseph J Kennedy

Joseph Kennedy is a hydrologist at the USGS Oregon Water Science Center.

Joseph Kennedy initially started working for the USGS at the Pacific Islands Water Science Center in 2016 immediately after receiving his M.S. degree from the Department of Geology and Geophysics (now Earth Sciences) at the University of Hawaiʻi at Mānoa. His graduate research was the first to use small unmanned aerial vehicles to collect time-series thermal imagery of coastal groundwater discharge tidal dynamics. The time-series imagery was coupled with simultaneous geochemical tracer analysis to determine groundwater discharge rates and nutrient flux to the coastal zones of Maui. In February of 2020 he transferred to the Oregon Water Science Center to expand his experience as a hydrologist. His research investigations range from storm-water sampling for pesticide prevalence, to quantifying the impacts of non-native plant species on freshwater availability in Hawaiʻi, to using computer programming for analyzing a variety of groundwater, surface water, climate, and remote sensing datasets to assess water-resource issues.

Development of a Surface Water Index of Permanence (SWIPe) Database to Assess Surface Water Availability for Ecohydrological Refugia

Surface-water availability has been identified as one of the biggest issues facing society in the 21st century. Where and when water is on the landscape can have profound impacts on the economy, wildlife behavior, recreational use, industrial practices, energy development, and many other aspects of life, society, and the environment. Projections indicate that surface-water availability will be gen

Cloud water interception in Hawai‘i: Developing capacity to characterize the spatial patterns and effects on water and ecological processes responses in Hawai‘i

Cloud-water interception (CWI) is the process by which fog or cloud water droplets are captured and accumulate on the leaves and branches of plants, some of which drips to the ground. Prior studies in Hawai'i indicate that CWI is highly variable and can contribute substantially to total precipitation. In this study, we monitored CWI and other processes at five mountain field sites on the Islands o
