California Water Virtual Tour     Hydrology and Climate Change 101     Water Conservation     Water and Drought Online Seminar Series

As a cooperative specialist, my mission is to design science-based and practical policies to balance competing water uses and interest in California’s water resource systems; provide the best scientific knowledge to our society.

How We Work

  • I conduct problem-solving research in water resources management using the shared vision approach; meaning we talk to people and bring knowledge to understand issues from different perspectives, a more balanced approach to water problem solving.
  • I provide technical and scientific support to planning and decision making processes as a neutral party, we collaborate with UC Davis experts and research centers (Watershed Science Center).
  • I work with public and private agencies to address their needs regarding how to improve the water management of their system. This scientific support can vary from water budgets, optimization and simulation models, water use efficiency, urban water management, reservoir re-operations, risk analysis, to climate change analysis in a particular basin or region.
  • If you have an issue or question regarding how to better manage water in your basin/region, please send me an email (Samuel Sandoval).

 

Water Management

 

Provide support to basin management plans and decision making process. Our research group specializes in decision support systems (DSS), such as water planning, optimization and hydrologic models. These tools help to test different water management alternatives, usually called “scenarios”, to quantify the potential benefits and drawbacks that each policy offers. These models are built conjunctively with stakeholders, water operators and all the people involved in the water management of a basin.

California Water Virtual Tour

There is no other state where water and economic development is so tight than in California; since the gold rush, water has been the engine that have promoted economic and social development in the state. Water is still a precious resource in California. The main goal of the California Water Virtual Tour (CWVT) is to provide the fundamental knowledge of water in California. A series presentations (called Virtual Tour) recorded in a workshop will be available from experts (called tour-guides) of a several regions in California (called Stops).

We conduct water budget analysis to estimate consumptive water use, applied water, water use efficiency and potential water savings. This analysis helps to identify potential water savings in a basin. A successful project of water use efficiency have been done in Pajaro Valley located in the central coast of California, this project was partnered with the Pajaro Valley Water Management Agency and the local UC Cooperative Extension offices in Santa Cruz county.

 

 

 

Hydrology and Climate Change

hydrology-climate-change.jpgI conduct talks about hydrology, groundwater hydrology and climate change, known as:  “Hydrology and Climate Change 101.” These talks may range from 20 to 50 minutes and include a wide variety of audiences: teachers, local and state agency personnel, farmers, citizens, planners, water/irrigation district managers and personnel, local politicians, people in the water supply industry, among others. If you have an educational program for farmworkers in either English or Spanish, please contact us (samsandoval@ucdavis.edu), we will be delighted to provide these talks to your audience. In March 2012, a successful talk was performed for 140 Spanish speaker farmworkers in collaboration with the Napa Valley Grapegrowers Association; please contact us to collaborate.

 

Conjunctive  Surface Water and Groundwater Management

IMG_0030.JPGWe are involved in a multidisciplinary team to understand the surface water and groundwater interactions in the Scott River. Our collaboration in this project is in the analysis of rainfall data and its distribution across the valley, as well as in streamflow data and estimating its values in ungagged streams. Together, scientist, engineers and the Scott Valley community are working to understand the importance of surface water and groundwater management for agriculture and environmental purposes. This is a collaborative project with Thomas Harter, the groundwater hydrologist expert at UC Davis.
