Elizabeth Jachens

Elizabeth Jachens is a hydrologist with the U.S. Geological Survey in the California Water Science Center in the Groundwater Availability and Use Assessments project.

Elizabeth graduated with her Ph.D. in Water Resources Engineering from Oregon State University in March of 2020. Her research focused on the use of recession analysis to characterize watershed responses to drought. She earned an M.S. in Water Resources Engineering and a Graduate Certificate in Water Conflict Management and Transformation, both from Oregon State University in 2019. Elizabeth graduated with a B.S. in Civil Engineering with a minor in math from California State University, Chico in 2015.

Lower Salinas Valley Hydrologic Models: Climate Data

This digital dataset contains the climate data used for the Lower Salinas Valley Hydrologic Models (Salinas Valley Integrated Hydrologic Model (SVIHM) and Salinas Valley Operational Model (SVOM)). The monthly climate data for the Lower Salinas Valley Hydrologic Models are based on the regional climate data for the Salinas Valley Hydrologic System [Hevesi and others, 2022]. To develop the monthly c

Salinas Valley Operational Model: Input Operational Data (ver. 2.0, September 2023)

This digital dataset contains the surface water operational data used for the Salinas Valley Operational Model (SVOM) including the timeseries data and the operational rules. While much of the input data is shared between the Salinas Valley Operational Model (SVOM) and the Salinas Valley Integrated Hydrologic Model (SVIHM), the SVOM has additional input data specific to the purpose and function of

Salinas Valley Hydrologic System: Regional Climate Data

This digital dataset contains the climate data used for the Salinas Valley Hydrologic System, including the Salinas Valley Watershed Model (SVWM) and the Lower Salinas Valley Hydrologic Models (Salinas Valley Integrated Hydrologic Model (SVIHM) and Salinas Valley Operational Model (SVOM)). The climate data include spatially distributed daily precipitation, maximum and minimum air temperature, and

Lower Salinas Valley Hydrologic Models: Discretization Data (ver. 1.1, July 2023)

The Lower Salinas Valley Hydrologic Models’ discretization data includes a shapefile of the model domain and layers and a shapefile of the water balance subregions. The Lower Salinas Valley Hydrologic Models include a historical model, the Salinas Valley Integrated Hydrologic Model (SVIHM) and a reservoir operations model, the Salinas Valley Operational Model (SVOM).

Salinas Valley Hydrologic Models: Surface Water Data

This digital dataset contains the surface water data used for both the Salinas Valley Watershed Model (SVWM) and the Lower Salinas Valley Hydrologic Models (Salinas Valley Integrated Hydrologic Model (SVIHM) and Salinas Valley Operational Model (SVOM)). The surface water dataset includes describes two regions of the Salinas River Watershed; the upper region is occurs primarily within San Luis Obis

Water Availability of the Salton Sea Watershed

Throughout history, the Salton Sea has formed and dried up due to flooding from the Colorado River. It was most recently formed in 1905 when the Colorado River broke through an irrigation canal and flowed uncontrolled into the Salton Sea watershed. The Salton Sea is a terminal lake (it has no outlets). It is also in transboundary watershed, with area in both the state of California and Mexico’s...
