Hydrogeophysical parameter estimation for aquifer characterisation in hard rock environments: A case study from Jangaon sub-watershed, India

  This study was carried out to determine a theoretical relationship between geo-electrical data and hydraulic parameters by modifying the theories previously developed in laboratories and up-scaling the processes of pore network structures into field scale parameters. A linear relationship between transmissivity and formation factor has been developed and consequently tested on data from a typically hard rock...

Seasonal variability of heat content and isothermal layer in the Bay of Bengal

  Heat content and isothermal layer variations in the Bay of Bengal have been investigated in this study using 52 years (1950 to 2001) global ocean monthly analysis datasets based on the simple ocean data assimilation (SODA) package. The annual cycle of heat content estimated from surface to fixed depths (67.5, 125 and 500 m) and isothermal layers (26, 20 and 10°C) show seasonal variations for the entire...

Hydrogeochemistry of groundwater in Port Harcourt City, Southern Nigeria

  Rapid deterioration of groundwater quality in Port Harcourt, Southern Nigeria; due to unregulated exploitation resulting from increasing growth in the oil and gas production activities has become a major concern. The predisposition of groundwater to pollution and the realization of its serious health and economic consequences demand knowledge of the ambient groundwater quality and of the processes leading to...
