The vast continent of Africa is a land of contrasts—from the sophisticated urban and industrial centers of Cape Town and Johannesburg to the rural bushlands and mountains of Zimbabwe and Kenya. As in the rest of the world, groundwater resources in Africa are critical to human livelihood, agricultural and industrial development, and maintenance of aquatic ecosystems. Widely available scientific ...

The phylogenetic relationships within the piranhas were assessed using mitochondrial sequences with the aim of testing several hypotheses proposed to explain the origin of Neotropical diversity (palaeogeography, hydrogeology and museum hypotheses). Sequences of the ribosomal 16S gene (510 bp) and control region (980 bp) were obtained from 15 localities throughout the main South American rivers ...

This study examines the effect of pumping, hydrogeology, and pesticide characteristics on pesticide concentrations in production wells using a reactive transport model in two conceptual hydrogeologic systems; a layered aquifer with and without a stream present. The pumping rate can significantly affect the pesticide breakthrough time and maximum concentration at the well. The effect of the pump...

this book review presents the merits and drawbacks of engineering geology for underground works edited by gattinoni et al. and published by springer in 2014. this book summarizes most of the problems an engineer may encounter in underground design, construction and operation.this book is useful for students and professionals in engineering geology and is also referable for scholars in relevant ...

I would like to bring to the attention of the hydrogeology community an ongoing inconsistency in the published literature concerning the use of the term flux. The definition of flux that is most pertinent to Ground Water readers comes from the field of transport phenomena, where the flux of some quantity (e.g., mass, energy, momentum, entropy) is defined as the flow rate of that quantity per un...
