Mass transport modeling of an industrial belt using visual MODFLOW and MODPATH: A case study

  Groundwater in an industrial belt (namely Upper Kodaganar River basin, Tamilnadu, India) is polluted due to discharge of untreated effluents from 80 operating tanneries. Total Dissolved Solids (TDS) measurements vary in and around the clusters of tanneries from 2,000 mg/l to 30,573 mg/l in open wells. A mass transport model was constructed to study the contaminant migration using Visual MODFLOW and MODPATH....

Here today, gone tomorrow? Targeting conservation investment in the face of climate change

  To optimize the use of scarce resources, it is imperative to target conservation investment wisely. We discuss the impact assessment of potential climate-driven shifts in species distributions on the future conservation utility of a present-day reserve design. We provide examples using breeding bird survey data for 150 species in the eastern USA, and two predicted future species distributions models. Using...
