Final answer:
Groundwater overdrawing can cause land subsidence, leading to infrastructure damage, increased flooding, and ecosystem disruption. It can worsen water resource issues by causing saltwater intrusion and lowering freshwater availability.
Step-by-step explanation:
Land subsidence due to overdrawing can cause several issues. Overdrawing groundwater can create a cone of depression, which may result in groundwater mining, or the significant lowering of the regional water table.
This overuse of groundwater sources can lead to detrimental effects such as depletion of rivers and lakes, increased saline water intrusion in coastal areas, and negative impacts on ecosystems due to lowering of the water table.
Moreover, sustained withdrawal of groundwater can lead to land subsidence, which is the gradual sinking of the land. Subsidence can have severe consequences, including damage to infrastructure, increased flooding, and disruption to natural habitats. Additionally, it can contribute to compounding water resource issues like saltwater intrusion, which can degrade freshwater supplies even further.
