DescriptionThe successful investigation of the hydrogeology of an area depends on the collection of reliable field data. Field Hydrogeology, Third Edition follows a systematic approach to completing a hydrogeological study and explains how to decide on the measurements that are needed and on the instruments and techniques required. Measurements that are needed and on the instruments and techniques required. Measurements of groundwater levels, rainfall and evaporation spring and stream flows and the use of ground water tracer techniques are covered. There is a great deal of practical information on all aspects of planning and completion of field investigation and on the interpretation of field investigation and on the interpretation of field evidence. Advice on safety is also included.
This third edition has been fully revised and updated to bring the book into line with developments in environmental regulations. The order of the chapters reflects the structure of a hydrogeological project and the development of a conceptual model up to completion of a report. The focus is on current practical applications of hydrogeological investigations using new case histories and a new chapter on specialist techniques has been included.
- Handy pocket-size for field research
- Features case histories
- Focuses on practical applications
- Contains a new chapter on groundwater investigations
