  Groundwater Divides and Erosion of Terrestrial Horizons: A Critical Review of the Academic Paradigm - Mike Buchanan, 2022   Introduction The concept of groundwater divides has been a cornerstone of hydrogeology and broader hydrological sciences for decades. However, accumulating evidence challenges the traditional view of these divides as fixed and distinct boundaries. This paper critically examines the prevailing academic paradigm, focusing on the impact of tectonic activity, gravitational forces, and climatic erosion on terrestrial horizons. While the discussion is rooted in hydrogeology, the subject’s relevance spans across geoscientific disciplines due to its broader implications for terrestrial erosion processes, landscape evolution, and resource management. The Traditional Paradigm of Groundwater Divides Historically, the dominant model has operated under two main assumptions: Sharp and distinct groundwater divides – These are viewed as clear-cut ...

  The Ethical Responsibilities of a Karstologist: A Comprehensive Overview Mike Buchanan 2023 A Philosophical Expression An ethical karstologist embodies a profound responsibility to the intricate karst landscapes they study, recognising these environments as vital ecosystems that sustain diverse life forms and human communities. Their duties extend beyond scientific inquiry; they must advocate for the preservation of these fragile ecosystems, balancing the pursuit of knowledge with a commitment to sustainability and conservation. By fostering a deep respect for the interconnectedness of all living things, an ethical karstologist seeks to illuminate the delicate relationship between human activity and nature, ensuring that their research contributes to a harmonious coexistence that honours the past, nurtures the present, and safeguards the future of karst landscapes. This integrated approach champions the stewardship of these unique environments, emphasizing that the integrit...

The Worlds Greatest Karst Disaster Involving one hundred years of well-intended anthropogenic destruction, which is destroying a unique karst groundwater system and habitat The city of Johannesburg in South Africa had its beginnings 1886 when gold was discovered on the Witwatersrand by an Australian prospector named George Harrison. Most gold mines in the Johannesburg (JHB) area ceased operation in the late 1970s. These closed mines were considered as future potential reserves. Interspersed amongst them were a few productive mines, which continued to pump out invading groundwater. The mining houses had long relied upon the South African government to help finance the back pumping of ingressing groundwater to enable access to continuous supplies of gold from deeper gold rich seams. At the time many leading academics and others were unaware that the water they were back pumping came from the abundant, dolomitic rock that surrounds Johannesburg. Furthermore, these groundwater re...
