Research Interests:
Dr. Keyantash conducts hydrologic research that examines the timing and intensity of water fluctuations within reservoirs of the hydrosphere. These efforts include numerical analysis of the patterns and severities of droughts, determining fluctuations in ground- and surface water storage based on gravitational measurements from satellites, and understanding the timing of spring runoff from gauged (and ungauged) river basins. Regarding the latter research topic, he further utilizes artificial neural network models to predict the effects of the streamflow fluctuations on California salmon populations. In addition, Dr. Keyantash is involved in the development of elementary/middle school classroom science materials and teacher training for the Los Angeles Unified School District, via the usage of a science inquiry approach.
