Land subsidence (LS) is a gradual settling or sudden sinking of the Earth's surface owing to subsurface movement of earth materials. More than 80% of the identified LS in the nation is due to our exploitation of underground water (UW). This report illustrates the 3 basic mechanisms by which human influence on UW causes land subsidence: compaction of aquifer systems, dewatering of organic soils, and mass wasting through dissolution and collapse of susceptible earth materials. Also examines the role that water-management groups play in mitigating subsidence damages. Color and B&W photos, maps, and drawings.

This title offers more than 100 papers originating in 20 countries, covering research on a widening range of methods for recharge enhancement and groundwater quality protection and improvement. These include: bank filtration; aquifer storage and recovery; and soil aquifer treatment, as well as rainwater harvesting and pond infiltration. The emphasis is on understanding subsurface process to improve siting, design and operation and to facilitate use of stormwater and reclaimed water, particularly in water-scarce areas.
