Groundwater Monitoring Wells:

Groundwater Monitoring Wells Have Long Been Used To Measure Water Levels And Quality In The Subsurface. These Wells Consist Of A Pipe Inserted Into The Ground, Allowing Direct Access To The Water Table. While Groundwater Monitoring Wells Have Been The Traditional Choice For Water Measurement, They Have Certain Limitations:

– Limited Spatial Coverage: Monitoring Wells Provide Point Measurements At Specific Locations, Making It Challenging To Obtain A Comprehensive Understanding Of Water Movement Across A Larger Area.

– Expensive And Time-Consuming: Installing And Maintaining Monitoring Wells Can Be Costly And Time-Consuming, Especially When Multiple Wells Are Required To Cover A Large Study Area.

– Limited Temporal Resolution: Measurements From Groundwater Monitoring Wells Are Typically Periodic, Providing Snapshots Of Water Levels At Specific Time Intervals.
