Learning objectives
- outline the methodology for designing groundwater surveying programmes (GSP), including the main desk and field activities to be performed;
- interpret the results from geophysical surveys, exploration borehole logging, pumping tests and groundwater observations within the context of
GSP; - plan a GSP for a certain area based on the analysis of available data and field conditions;
- interpret hydro(geo)logical time series and spatial data;
- learn methods and procedures used in groundwater monitoring;
- design a groundwater monitoring network and to assess the required measurement frequencies
