Research: Ecohydrology of agroecosystems and lake-groundwater interaction in the Salton Sea basin

Dr. Sandra Armengol Vall

I am a Postdoctoral Scholar at the Department of Environmental Sciences, University of California Riverside. My research is aimed at gaining knowledge and understanding in the use of chemical and isotopic tracers in hydrogeology. My main areas of expertise include the use of conventional chemical techniques, geochemical modelling and geostatistics to identify the groundwater provenance in aquifers and to study water-soil interactions including salinization processes.

I have five years of experience in analyzing groundwater chemistry and collecting rainwater samples. I worked in groundwater related issues in Spain (Onyar River Basin, Llobregat River Basin) and North (Iberá Estuary) and Central (Matanza-Riachuelo River Basin) Argentina. I have planned and conducted many surveys, including building a rainwater monitoring network for a 2300 km2 basin.

Dr. Adam Schreiner- McGraw

I am a postdoctoral scholar at the University of California Riverside. I obtained my PhD from Arizona State University studying ecohydrological controls on focused groundwater recharge. My background is primarily in observational hydrology with expertise in environmental sensor networks, eddy covariance measurements, cosmic-ray neutron soil moisture sampling, and hydrologic modeling. My scientific philosophy is to combine high-resolution hydrologic observations with state-of-the-art watershed models to build deep understandings of the problems that I study. I am motivated by scientific questions that aim to improve our ability to predict and manage water resources in the future, particularly in water-stressed regions. This includes the hydrologic impacts of land cover change and climate change, and connections between the hydrologic cycle and ecology, or ecohydrology. My main project focuses on understanding surface-groundwater interactions in the California Central Valley within the context of climate change. 

Undergraduate Students

William Scott Burgess  

Major: Mathematics, University of California Riverside

Research: As a Digital Agricultural Fellow, I am working with Dr. Hoori Ajami and Dr. Adam Schreiner-McGraw to design computational methods for determining groundwater response to precipitation droughts. I plan to pursue a career in agricultural technology, or technology as it relates to natural resources more broadly; specifically, I am interested in the intersection of these emerging fields and the financial sector.
