Will the new industries with high water consumption enter the regions with insufficient water resources, will aggravate groundwater overpumping and cause stratum subsidence?
Knowledges
What does the government do to prevent and control stratum subsidence at this stage?
Knowledges
The stratum subsidence is mainly related to the extraction of groundwater by deep water wells. Will the extraction of shallow groundwater by agricultural water wells cause stratum subsidence?
Knowledges
How to find the area of stratum subsidence?
Knowledges
Excessive pumping of groundwater is the main cause of stratum subsidence. What are the specific measures for restricting groundwater extraction in severely subsided areas?
Knowledges
What is the effectiveness of the prevention and control of stratum subsidence over the years?
Knowledges
What value (velocity) of stratum subsidence can be set as a safety, warning or dangerous index for flooding and drainage?
Knowledges
Do countries in the world also have the problem of stratum subsidence?
Knowledges
What is the progress in the prevention and control of stratum subsidence over the years?
Knowledges
Is it suitable to delineate the subsidence zone by the surface elevation?
Knowledges
What value (or rate) of the rise and fall of the groundwater level can be set as a safety, alert, or risk indicator for flooding and drainage?
Knowledges
Is it appropriate to delineate the subsidence area by the subsidence rate?
Knowledges
How is the abolished "severe stratum subsidence zone" defined?
Knowledges
What should farmers who live by the sea do to continue breeding and keep their homes from sinking?
