A simple approach for the analysis of the structural-geologic control of groundwater in an arid rural, mid-mountain, granitic and volcanic-sedimentary terrain: The case of the Coquimbo Region, North-Central Chile

A practical approach for the assessment of surface water and groundwater resources in rain-fed mid-mountain domains of arid to semi-arid zones is much needed, especially in rural areas for which groundwater is the only reliable and permanent water supply source. This is the case in the Coquimbo region (29°15′- 32°10′ S latitude) of north-central Chile, where groundwater is needed for human consumption but also for agricultural and mining activities at a small to medium scale. This paper examines the usefulness of community knowledge, as encoded in the historical record, for identifying water resources. The existing record of wells and springs in the Coquimbo region is used as a guide to the identification and characterization of structural patterns that may influence the distribution of water resources. The proposed approach combines simple graphical, statistical and geostatistical methods to identify patterns, likely related to local and regional structural controls that influence the distribution of groundwater resources. In the Coquimbo area, these influences tend to align in NW and NE orientations that approximately coincide with regional geological trends. The methodology presented has the potential to form a first step in the search for additional water resources in the Coquimbo region, and may be useful for targeting detailed field studies on the basis of community and historical knowledge in many arid and semi-arid rural areas.

Wells in the Historical Records of the Joseon Dynasty, Korea

Many historical records document that people havemanually dug wells for daily and military water usesince ancient times. The oldest record of wells in Koreais from the foundation mythology of the Silla Dynasty(57 BC through 935 AD). According to the “SamgukYusa,” which was compiled at the end of the 13thcentury, Hyeokgeose, the founder of the Silla Dynasty,was hatched from an egg laid from a white horse neara well named Rajeong in 69 BC. When he was 13 yearsold, six clans recognized Hyeokgeose as king. A dragonappeared at a well named Alyoungjeong and bore ababy girl from its left armpit in 53 BC. The baby wascalled Alyoung after the well, and later King Hyeokgeosemarried her. The well where Alyoung was born is theoldest well in existing Korean historical documents.The Joseon Dynasty (1392 through 1910) holds themost historical records in Korean history. The Annalsof the Joseon Dynasty, which is called “Joseon WangjoSillok,” is one of the most important historical documentsin Korea and has been registered as a Memory of theWorld by UNESCO.
