Abishek Singh, Ph.D., is Vice President of Intera’s Western Region based out of Los Angeles. His professional experience has focused on research and application experience in groundwater and surface water modeling, planning and decision analysis, risk and uncertainty analyses, optimization techniques, and temporal/spatial statistics. He has expertise in developing, calibrating, and applying hydrologic and data-driven models to support robust water-resources decision-making.
In a recent webinar presented by Intera, Dr. Singh gave a presentation explaining what groundwater models are, uses for groundwater models, how groundwater models work, and provided some case studies.
Subsidence of land surfaces has increasingly become a greater concern around the world as groundwater has continued to be depleted due to increase water demand while surface water depletion means that populations increasingly look to use subsurface water.
The lowering of Earth’s land surfaces promises to be a major problem for urban and rural regions and mapping these threats accurately may prove important to plan, prevent, and minimize this threat.
Using a literature review and spatial analysis, it is evident that some 34 countries are at major risk in the coming decades for major subsidence of their land surface. In particular, a recent mapping effort that looks at every 30 arc seconds resolution across the globe identified that very flat areas with unconsolidated sediments accumulated in alluvial basins or coastal plains are the most vulnerable.

Department of Conservation awards $1.5M in grants to support State’s Groundwater Management Plan
“The California Department of Conservation (DOC) today announced five watershed coordinator grants totaling $1.5 million to support regional sustainable groundwater management goals. The grants will go to organizations around the state within medium- and high-priority groundwater basins. “California’s world-class economy – its unparalleled agricultural sector, diversity, and abundance of industry and communities of all sizes and geographies — depends on water, and with the reality of climate change, that increasingly means groundwater,” DOC Director David Shabazian said. “Groundwater is a critical resource that we must manage more intently to meet today’s needs while also ensuring adequate water supply in the future. These grants, which support the goals of the Sustainable Groundwater Management Act (SGMA), help us do that.” … ” Read more from the Department of Conservation here: Department of Conservation awards $1.5M in grants to support State’s Groundwater Management Plan
Managing groundwater overdraft – combining crop and water decisions (without salinity)
” … This post summarizes some recent research examining conjunctive water management for agriculture integrating hydro-economic optimization models on two timescales, neglecting for now salinity effects on crop yield: an intermediate term 10-year stochastic model of water and crop management spanning dry and wet years, and a far horizon (100 years of 10-year stages) management model which embeds intermediate-term model to represent longer-term aquifer targets (Yao 2020). The modeling was applied for conditions similar to California’s San Joaquin Valley. Integrated economically-driven optimization of permanent and annual crop acreages and water management for these two timescales identifies some economically-promising strategies considering both crop decisions and water management to mitigate groundwater overdraft. … ” Read more from the California Water Blog here: Managing groundwater overdraft – combining crop and water decisions (without salinity)
Dusty barren fields or thriving farmland and habitat? This bill creates a better vision for California’s future

Borrego Springs – Southern California, but a World Apart
A four part series from the Local Government Commission
“Amidst drought, groundwater regulation, and economic hardship, the media portrays Borrego Springs as a village “drying up” in the desert – running out of water – soon to be the next California ghost town.
Like many aspects of the desert, there’s more to the Borrego Springs community than meets the eye. In the crevices of the valley’s rocky floor, wildflowers blossom in exuberant hope. In the shade of the Palo Verde trees, Coyote Creek babbles through the sandy slopes with perseverance.
From corner to corner, the community is banding together: evaluating how to live within the constraints of this remote locale, charting a course that integrates civic engagement with environmental, social and economic priorities – to achieve their goal of a thriving, resilient future.
This is their story. … ”

Kamyar Guivetchi, Manager of DWR’s Division of Planning has often referred to Flood Managed Aquifer Recharge (or Flood MAR) as a “moon shot” for recharging depleted groundwater basins, but just how much Flood MAR can contribute to groundwater recharge in a watershed is unknown. However, the Department of Water Resources’ Integrated Watershed Management staff is underway with a pilot study to look at the potential for Flood MAR in the Merced River watershed.
At the October meeting of the California Water Commission, Mr. Guivetchi and David Arrate, Senior Water Resources Engineer with the Department of Water Resources, gave a presentation on the study and shared some of the preliminary results.
At the Groundwater Exchange, we’re working to update the website and adding new features.
One of those is the new Video Gallery, where you can find introductory videos on SGMA, SGMA videos in Spanish, and special topic videos on groundwater recharge, Integrated Regional Water Management, and more!
The Groundwater Exchange video gallery can link to videos posted on YouTube, Vimeo, or Facebook, so if you have a video to add, send the link to firstname.lastname@example.org.
