Projects

NASA JPL Algorithm Definition Team 1514215

“Estimating snow water equivalent in mountainous areas from passive microwave measurements: Comparing two candidate algorithms.” We are exploring the theory and pragmatics of optimally defining reaches for SWOT rivers. PI: Durand

NASA New Investigator Program: NNX13AB63G

“Estimating snow water equivalent in mountainous areas from passive microwave measurements: Comparing two candidate algorithms.” In this project, we will perform a side-by-side comparison of two algorithms to estimate SWE in mountainous areas. We will apply both algorithms to estimate basin-wide SWE over large regions (on the order of 100,000 km2) in the Colorado Rocky Mountains and the Sierra Nevada. PI: Durand

SWOT Science Definition Team: NNX13AD96G

Evaluating feasibility and accuracy of three algorithms for estimating discharge from SWOT measurements.” This project determines membership in the Science Definition Team, which will guide the decisions made by the SWOT team in determining final hardware specifications, algorithms, etc. We will contribute by investigating algorithms for estimating river discharge from SWOT. PI: Durand

NSF Geoscience & Education GEO-1203035

“From classrooms to geoscience careers: Developing, testing and disseminating a high school module on modeling water in urban environments.” This project will promote high school interest in geoscience career through a novel approach to teaching hydrology concepts. PI: Durand. Co-Investigators include Jason Cervenec, Stephen Gordon, and Howard Greene.

NASA MEASURES NNX15AH05A

“Development of pre-SWOT ESDRs for global surface water storage dynamics”. This project will create surface water Earth Science Data Records of surface water altimetry over the world’s large rivers, lakes, and reservoirs. CK Shum (SES) is a Co-PI. Durand is the lead Co-PI at Ohio State.

NSF Dynamics of Coupled and Natural Human Systems BCS-1211986

“Fish, floods, and societies: exploring social, ecological, and hydrological regime shifts in the Logone Floodplain, Cameroon”. This project will examine the effects of the large number of canals being used to divert flow from the Logone River for fishing purposes. We will construct a coupled model of the hydrology, hydraulics, fisheries and human systems. PI: Mark Moritz, of OSU Anthropology, leads the laboratory dedicated to this project, Modeling Regime Shifts in the Logone Basin (MORSL; link).

NASA Instrument Incubator Program NNX14AE68G

“UWBRAD: Ultra Wideband Software Defined Microwave Radiometer for Ice Sheet Subsurface Temperature Sensing”. This project involves development of a microwave radiometer to sense ice sheet temperature at depth. PI: Joel Johnson of OSU Electrical Engineering; Science PI: Ken Jezek, Prof Emeritus of OSU Earth Sciences.

NASA Earth System Science Fellowship: NNX13AN53H

“Improving the understanding of snow water equivalent and melt timing in the Sierra Nevada by assimilating AMSR-E L2A brightness temperature into a land surface model”. This fellowship was awarded to Dongyue Li. This project uses high-resolution land surface hydrology modeling to assimilate passive microwave measurements to better understand snow accumulation in the Sierra Nevada.

NASA Earth System Science Fellowship: NNX14AT34H

“Estimating Mountain Snowpack Storage via Assimilation of Snow Cover Fraction into a Regional Climate Model”. This fellowship was awarded to Melissa Wrzesien. This project uses coupled regional climate modeling and remote sensing measurements of snow cover fractions estimate large-scale snow accumulation patterns.

NASA Earth System Science Fellowship: NNX15AN33H

“Determining Controls of Global Runoff From the Upcoming Surface Water and Ocean Topography (SWOT) Satellite”. This fellowship was awarded to Stephen Tuozzolo. This project explores global datasets to attempt to determine global controls on runoff. This should lay the groundwork for utilizing SWOT to further elucidate this question.
