The Hydrogeological Field Course is part of Special Modul SM9 "Hydrogeological Methods" of the MSc TropHEE and scheduled for the 2nd semester. This block course complements the Water Analysis Course scheduled for the 1st semester. Water Analysis containes lectures and a practical part with (surface) water sampling, measuring water temperature, EC, pH, oxygen concentration and alkalinity in the field as well ion concentrations in the lab. This practical part of course 3214 is documented in another report and deals with water sampling in more detail. The water sampling part of field course 3417 repeats this topic in this report.
TropHEE Modul Handbook names as goals of this course: "The students are enabled to apply basic field techniques to characterize groundwater levels, groundwater flow fields, and to characterize aquifers in term of hydraulic properties. Students acquire methodical skills to use standard laboratory equipment to analyse water samples and to evaluate the results. Through the hands-on field and laboratory work they gain soft skills such as organizational skills, team working skills, communication skills, and data presentation skills."

Zusammenfassung der Kapitel (Chapter Summaries)
- Introduction: This chapter provides a general overview of the course, its objectives, and the topics covered. It outlines the practical exercises and the methods employed, including water sampling, water level measurements, stream discharge measurements, and pumping tests.
- Construction of groundwater table map: This chapter details the methodology and results of constructing a groundwater table map based on measurements taken in several wells on campus. It explains the use of leveling instruments, data analysis using LibreOffice Calc and GNUplot, and the calculation of groundwater gradients and flow directions.
- Stream discharge measurements: This chapter examines three different methods for measuring stream discharge: the float method, the flow meter method, and the tracer method. It discusses the strengths and weaknesses of each method, explores potential sources of error, and compares the results obtained for the Darmbach stream.
- Pumping test: This chapter describes a pumping test conducted in a well in Arheilgen. It explains the methodology, including the use of a diesel generator, electric pump, and data loggers for water level measurements. It explores the analysis of drawdown data using Theis' equation and the Cooper-Jacob simplification, and discusses the calculation of aquifer parameters such as transmissivity, conductivity, and specific capacity.
- Surface- and groundwater sampling: This chapter focuses on water sampling procedures, field measurements, and laboratory analyses conducted for surface and groundwater samples. It covers the techniques used for measuring water parameters such as temperature, EC, pH, oxygen concentration, and alkalinity. It also discusses the laboratory analyses carried out, including atomic absorption spectroscopy (AAS), ion chromatography (IC), and photometry.
