Groundwater Data Collection and Interpretation

IHE Delft Data Management

Target Audience

The course is addressed to postgraduates and professionals in hydrogeology and water resources management: civil engineers, environmental engineers, geologists and hydrologists who are engaged in the investigation, management, and protection of groundwater resources


The course intends to train participants up to the level that data collection and monitoring tasks can be individually performed. It will provide the principles of groundwater data collection and monitoring and the use of software to process and analyse the information.

The following outline provides a summary of the content of the course and includes the main areas of instruction and a list of problems that will be addressed :

- Introduction; Need for data collection and monitoring, Management and planning of surveys and networks
- Available data and basic surveys; How to handle available data?, Hydrogeological interpretation of remote sensing data, Hydrogeological mapping and well inventories
- Surface geophysical methods; Principles of geo-electrical surveying, Variable electrode distance techniques, Horizontal profiling, Hydrogeological interpretations
- Exploration drilling; Selection of well sites, Drilling methods and their applicability, Geological and geophysical well logging; water quality sampling, Well design criteria and design methods, Well development
- Pumping tests; Principles of pumping tests, Field guidelines and data processing, Preliminary interpretation, Analyses of constant yield tests
- Introducing monitoring networks; Introduction, Basic concepts and procedures
- Design of networks; Network density for estimating global mean, Monitoring of diffuse pollution, Monitoring of waste disposal sites, Network density graph, Determination of network density with Kriging, Determination of sampling frequency
- Instructional problems; Preparation of hydrogeological maps and sections, Interpretation of a Schlumberger measurement (GEWIN), Preparation of a well log, Analytical analysis of a step-drawdown test, Analytical interpretation of constant yield tests (AQUITEST), Error analysis using Kriging (GEO-EASE), Designing an adequate network (NETGRAPH), Interpretation of time series and assessing sampling frequency (FREQ)

Learning Objectives

Upon completion, the participant should be able to:
- 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
