Bacon, Auteur Editeur : Newcastle : Cambridge scholars publishing Année de publication : 2023 Importance : 1 fichier PDF ISBN/ISSN/EAN : 978-1-5275-0139-3 Note générale : Mode d'accès : accès au texte intégral par : - authentification après inscription à la plateforme EBSCOhost ou - adresse IP de l'École. Langues : Anglais (eng) Mots-clés : Groundwater flow Index. décimale : 628.1 Alimentation en eau. Traitement des eaux. Consommation d'eau Résumé : This book aims to synthesise knowledge on the advantages and utilities of electrical resistivity methods to reliably conceptualise the subsurface and hydrogeological processes, to improve groundwater flow and transport models. This edited book contains a total of nine chapters that cover geophysical investigations for groundwater flow studies and contaminant transport modelling from different sites across South India. All chapters emphasise the use of geophysical technical techniques for a better conceptualisation of sites where there is only limited borehole lithology data. The first chapter describes the development of hydrogeophysical inversions and describes a case study of the use of electrical resistivity tomography in groundwater modelling. The second chapter provides a case study of surface electrical resistivity to obtain aquifer parameters and conceptualisation for reliable simulation of groundwater flow. Chapter 3 explains how modelling techniques can help to deploy the geophysical investigations and also how electrical resistivity tomography can help to conceptualise the groundwater flow model of a coastal aquifer. Chapter 4 explains the utilities of time series electrical resistivity tomography for deriving hydrological parameters to support groundwater model Note de contenu : Summary: 1. Advantages of hydrogeophysics for improved conceptualisation and predictive modelling of groundwater flow process 2. A surficial electrical resistivity survey for estimating aquifer parameters for the regional characterisation of groundwater flow in a weathered granitic aquifer in the kodaganar river basin, tamil nadu, southern india 3.Isolation of a subterranean estuary in the shallow quaternary aquifer of the coleroon river, southern india, by numerical modelling and electrical resistivity investigations unsaturated pathways to aquifers: how important are they? Tanvi arora and shakeel ahmed 4. Unsaturated pathways to aquifers: how important are they? 5.Groundwater prospecting, scoping potential artificial recharge zones and flow modelling using ert and visual modflow in hard rock regions: a case study 6.Modelling of groundwater flow and contaminant mass transport guided by hydrogeological and geophysical investigations 7..Groundwater flow modelling for estimation of mine seepages at different mine development stages, telangana state 8..An integrated geophysical and geochemical survey to assess the fluoride contamination of the geophysical and groundwater flow modelling techniques for the identification of a low saline aquifer and to design optimal pumping rates in the coastal plains of the visakhapatnam district, south aquifer system at khaira village, munger district, bihar 9.Geophysical and groundwater flow modelling techniques for the identification of a low saline aquifer and to design optimal pumping rates in the coastal plains of the visakhapatnam district Electrical Resistivity and Other Geophysical Methods for Improved Modelling of Groundwater Flow [document électronique] / Surinaidu Lagudu, Auteur ; Charles G.D.

Boussoles de visée. Gyroscopes pour les relevés. Résumé : This book provides a unified approach for the two versions of Coriolis vibratory gyroscopes: Micro-Electro-Mechanical System (MEMS) and non-MEMS. It describes a new, differential mode of operation, analyzing the new triple mode gyro—rate, rate-integrating, and differential. The latter provides the gyro with an increased versatility by providing the maximum possible accuracy under changeable motion parameters and environmental conditions. The book also presents computer simulation, experiments, and test results on the rejection of external disturbances, and considers the fabrication processes of MEMS, metallic and quartz resonators. It will interest researchers, scientists, engineers, and students specializing in the field of inertial sensors, as well as engineers of digital control systems, and inertial sensors test-engineers. It can also be used as a reference book when designing vibratory gyros. Note de contenu : Summary : 1. Introduction 2. Operation principles of a vibratory gyroscope 3. Vibratory gyroscope's principal errors and mathematical models 4. Actuators and sensors to control a standing wave 5. Designs and fabrication technology of MEMS gyroscopes 6.
