different methods exist for the zonation of oil reservoirs based on petrophysical data and well logs. among them are: permeability-porosity cross polt, pickett and soder and gill methods. in this study a statistical zonation technique has been used for the marun and pazanan oil reservoirs in iran based on effective porosity, density, sonic, neutron and resistivity data. petrophysical interpreta...

This study performs district and local administrative level multi-hazard zonation of Nepal. As multiple natural hazards are frequent, their losses enormous, maps can provide important insights before the occurrence so that effective countermeasures preparedness efforts be designed implemented. To this end, weightage-based Nepal is performed considering 27,482 independent hazard events. We consi...

Climate change and accelerated rates in sea-level rise are expected to increase flooding erosion on the world's coastlines. Coastal managers planners face challenge of helping communities adapt changing coast. Traditionally hard engineering has been used defend coast, but as this option becomes unsustainable financially unviable, coastal increasingly employing planning policy mitigate risk pose...

There are insufficient resources available to manage the world's existing protected area portfolio effectively, so the most important sites should be prioritised in investment decision-making. Sophisticated conservation planning and assessment tools developed to identify locations for new protected areas can provide an evidence base for such prioritisations, yet decision-makers in many countrie...

BACKGROUND AND AIMS Plant species composition in wetlands and on lakeshores often shows dramatic zonation, which is frequently ascribed to differences in flooding tolerance. This study compared the growth responses to water depth of three species (Phormium tenax, Carex secta and Typha orientalis) differing in depth preferences in wetlands, using non-linear and quantile regression analyses to es...
