NATURAL AND CONTAMINANT CHEMISTRY OF FRESHWATER STREAMS, GROUNDWATER, AND WASTEWATER TREATMENT PLANT EFFLUENTS ON THE HAWAIIAN ISLANDSDate: September 24, 2019

Speaker: Dr. Larry Barber Abstract: Sustainability of freshwater resources on island ecosystems relies on a detailed understanding of the sources and loading of contaminants and their impact on water quality. Considerable attention has been given to constituents such as nutrients…

HYDROLOGICAL MODELING CHALLENGES IN HAWAII AND THE PACIFICDate: September 13, 2019 • 3:30 pm

Location: POST 723, UH Manoa Campus Speaker: Dr. Aly I. El-Kadi (Dept. of Earth Sciences & Water Resources Research Center) Abstract: Hydrological modeling in Hawaii and similar areas is challenging due to complicated hydrogeological features, steep topography, and variable climate…

STOCHASTIC MODELING OF THE EARTH SUBSURFACE: DEALING WITH UNOBSERVED NATURAL SYSTEMSDate: September 10, 2019

Speaker: Dr. Grégoire Mariéthoz Abstract: Many hydrological processes taking place at the Earth’s surface are directly observable, either through in-situ measurements or by using remote sensing techniques. In contrast, understanding properties of the subsurface poses formidable observational challenges. Firstly, measurements…
