Many of the large number underground works constructed or under construction in recent years are unfavorable terrains facing unusual situations and conditions. This is case subject study this paper: a tunnel excavated evaporitic rocks that experienced significant karstification problems very quickly over time. As result situation, causes may underlie rapid investigated novel methodology present...

São Pedro do Sul thermomineral aquifer system is located in the North of Portugal. Hydrogeochemistry and isotopic studies were conducted order to improve knowledge this groundwater system, known since ancient Roman times for their therapeutic properties. One spring (NT) three boreholes (AC1, SDV1 SDV2) have a mean temperature around 68 °C. Currently, these waters are mainly used thermal spas ge...

The Heuningnes Catchment in the Republic of South Africa was used as a case study this research to describe application saltwater fraction/quantification and hydrogeochemistry methods evaluate extent saline intrusion coastal aquifers. argument is that presence seawater incursion may be conclusively determined by combining examination major ions, fraction, stable isotopes water, bromide, geochem...

The Isti Su hot spring is located in southeast of Salmas, in Western Azerbaijan, Iran. The area is a small part of Sanandaj-Sirjan geological zone which hosts many hot springs. The magma chamber of Salmas region is the main heat source of the hot springs in Isti Su area. Abundant rainfall and relatively long duration of snowfall as well as several deep faults in the area create the best conditi...
