Here’s my tiny contribution for the community. This book is only 84 pages, written in Indonesian Language. It covers the very preliminary part of hydrogeology: definitions, hydrological cycle, water balance, aquifer typology, aquifer parameter, and physical-chemical properties of groundwater.
Many improvements will be addressed on several parts, mainly the image resolution. However, hi-res images will be available on this site.
