Characterization of Surface and Underground Karst Features,In general, the surface morphological and hydrogeological forms in evaporites are very similar to those in carbonates, although the dynamics of their genesis is different. Also, solutional forms in the evaporites have a shorter “life” than their equivalents in limestone or dolomite.fixed-joint 发表于 2025-3-25 09:36:53

Prevention and Remediation at Dam Sites and Reservoirs, examples of dam and reservoir problems in evaporites confirms this opinion. Much lower mechanical strength and much higher solubility when in contact with water (particularly if it is flowing or under pressure) determine that these rocks are dubious and hazardous foundations for dams.Wordlist 发表于 2025-3-26 01:20:42

Overview of Dams and Reservoirs in Evaporites, twentieth century, more than sixty dams have been affected by gypsum and salt dissolution problems. Some of the dams failed to retain water up to their design levels due to extensive leakage, some of them collapsed catastrophically, some others were abandoned, and some reservoirs suffer due to seveevaculate 发表于 2025-3-26 10:46:13
Book 2019aporites (gypsum and salt) is much greater than the solution of carbonates, and evaporites are particularly vulnerable at dam and reservoir sites..Moreover, the presence of evaporites in the vicinity of dams or reservoirs often leads to serious problems: numerous dams in countries around the world (RLS898 发表于 2025-3-26 13:14:46
Monitoring,ization of a good monitoring network, good instrumentation, and continuity of measurements are the important prerequisites for the protection of dam stability and the watertightness (impermeability) of the reservoir.勤勉 发表于 2025-3-26 19:49:42
Overview of Dams and Reservoirs in Evaporites,re solute pollution of the stored water. Numerous dams in evaporites, mostly in gypsum, need rehabilitation: e.g., in Algeria, Argentina, Armenia, Azerbaijan, China, Dagestan, Georgia, Germany, Guatemala, Iran, Iraq, Jordan, Peru, Russia, Switzerland, Spain, Tajikistan, Tunisia, USA, Uzbekistan, Venezuela.
