Declining groundwater storage expected to amplify mountain streamflow reductions in a warmer world - Nature Water

This study employs a high-resolution, integrated hydrological model extending 400 m into the subsurface. Application of the model in a representative headwater basin in the Colorado River shows that groundwater storage loss will amplify streamflow losses in a warmer world.

Well, my desktop's NVMe drive seems to have died? Question mark there since I'm not entirely sure yet what's going on.

Desktop suddenly hung up and a cold reboot later the Linux system can't mount /boot anymore. Running fsck and checking SMART status from a live Linux flash drive doesn't show anything wrong. Reseating the drive didn't fix the issues. Damn it, I only got this SSD earlier this year.

I'll prolly need to find a replacement drive at some point, but not yet sure if I've got the money to get one yet. If anyone's got any ideas to avoid needing to do that, please do say so. Suppose if there's ever a time to plug my Ko-Fi, it's now (also in my bio):

Groundwater Sustainability and Land Subsidence in California’s Central Valley

The Central Valley of California is one of the most prolific agricultural regions in the world. Agriculture is reliant on the conjunctive use of surface-water and groundwater. The lack of available surface-water and land-use changes have led to pumping-induced groundwater-level and storage declines, land subsidence, changes to streamflow and the environment, and the degradation of water quality. As a result, in part, the Sustainable Groundwater Management Act (SGMA) was developed. An examination of the components of SGMA and contextualizing regional model applications within the SGMA framework was undertaken to better understand and quantify many of the components of SGMA. Specifically, the U.S. Geological Survey (USGS) updated the Central Valley Hydrologic Model (CVHM) to assess hydrologic system responses to climatic variation, surface-water availability, land-use changes, and groundwater pumping. MODFLOW-OWHM has been enhanced to simulate the timing of land subsidence and attribute its inelastic and elastic portions. In addition to extending CVHM through 2019, the new version, CVHM2, includes several enhancements as follows: managed aquifer recharge (MAR), pumping with multi-aquifer wells, inflows from ungauged watersheds, and more detailed water-balance subregions, streamflow network, diversions, tile drains, land use, aquifer properties, and groundwater level and land subsidence observations. Combined with historical approximations, CVHM2 estimates approximately 158 km3 of storage loss in the Central Valley from pre-development to 2019. About 15% of the total storage loss is permanent loss of storage from subsidence that has caused damage to infrastructure. Climate extremes will likely complicate the efforts of water managers to store more water in the ground. CVHM2 can provide data in the form of aggregated input datasets, simulate climatic variations and changes, land-use changes or water management scenarios, and resulting changes in groundwater levels, storage, and land subsidence to assist decision-makers in the conjunctive management of water supplies.

Scientists map loss of groundwater storage around the world

Global water resources are stretched by climate change and human population growth, and farms and cities are increasingly turning to groundwater to fill their needs. Unfortunately, the pumping of groundwater can cause the ground surface above to sink, as the aquifers below are drained and the architecture of the ground collapses. For the first time, a new study maps this loss of groundwater storage capacity around the world.
