Geologic Nozzles
Sonic velocities of geologic fluids, such as volcanic magmas and geothermal fluids, can be as low as 1 m/s. Critical velocities in large rivers can be of the order of 1-10 m/s. Because velocities of fluids moving in these settings can exceed these characteristic velocities, sonic and supersonic gas flow and critical and supercritical shallow-water flow can occur. The importance of the low chara...
متن کاملHealth benefits of geologic materials and geologic processes.
The reemerging field of Medical Geology is concerned with the impacts of geologic materials and geologic processes on animal and human health. Most medical geology research has been focused on health problems caused by excess or deficiency of trace elements, exposure to ambient dust, and on other geologically related health problems or health problems for which geoscience tools, techniques, or ...
متن کاملObject-oriented Image Analysis for the Identification of Geologic Lineaments
In this work, a methodological framework employing image processing techniques has been developed and applied on a LANDSATETM+ image of Alevrada, Greece. Pre-processing of the satellite image was followed by edge detection performed on band 5 of the ETM+ image in order to obtain proper input data to the lineament identification system. NDVI, PCA and ISODATA unsupervised classification were appl...
متن کاملGeologic Storage of CO2
Dynamic imaging provides an effective way to integrate previous time-lapse data with current data in order to estimate a current model. We present two methods useful for continuous dynamic reservoir and subsurface monitoring. The first method is a stochastic method for the inversion of geophysical data. It uses the ensemble Kalman filter (EnKF) that we demonstrate using time-lapse surface seism...
