From the Department of Water Resources:
DWR has released an approximately 30-minute lecture-style presentation video about a key concept presented in the draft BMP document: the role of critical head in managing land subsidence. Groundwater managers and practitioners may be interested in gaining some insight on this topic when making decisions to comply with SGMA. This presentation explains the science and mechanics of subsidence, introduces the concept of critical head, and describes how subsidence can be managed using critical head. The video presentation also provides examples of subsidence and critical head data in the San Joaquin Valley.
See DWR’s Subsidence website for updates on resources and information about subsidence and groundwater management, such as a Subsidence 101 Video; also see our recent digital article.
For general inquiries about the Subsidence webpage or other programmatic topics, please contact: sgmps@water.ca.gov.
