Abstract A complete water analysis typically contains at least 65 chemical and physical parameters. This variety of parameters complicates temporal or spatial comparisons of different water samples. Hence, special hydrogeological diagrams, such as the Schoeller diagram, were developed to facilitate the evaluation and interpretation of analytical results of multiple samples. In conventional Schoeller diagrams, the concentrations of calcium, magnesium, sodium, chloride, sulfate, and bicarbonate/carbonate are plotted as points on logarithmic scales. Points of one analysis are connected to form characteristic signatures of each sample. Occasionally, resulting parallel signatures indicate a similar water genesis. Here, we present standardized Schoeller diagrams and introduce a practical Matlab tool for this purpose. Standardization means that the different logarithmic axes are shifted towards each other so that the signature of a selected sample becomes a horizontal line. This procedure greatly facilitates comparisons of water samples to the chosen standard and increases the informative value of the diagrams. However, manual implementations of standardizations are arduous and time-consuming, as a single calculation of the relocation of each axis is necessary. In addition, the calculations must be repeated if another sample is chosen as the standard. We developed a Matlab tool that allows the fast generation of standardized Schoeller diagrams with many options and implements user-specific preferences with just one command. Probably the most useful feature is that users can choose which parameters are displayed, opening up new areas of application for Schoeller diagrams.

Zusammenfassung Bei der Beschreibung von Grundwasserleitern wird davon ausgegangen, dass diese in der Zeit statische Systeme darstellen, d. h. die Grundwasserleiter in Hinblick auf ihre Durchlässigkeit und Speichervermögen sowie auf ihren Lösungsinhalt zeitlich unveränderlich sind. Betrachtet man jedoch die landschaftsgeschichtliche Entwicklung eines Grundwasserleiters über geologische Zeiträume, so erkennt man, dass Grundwasserleiter dynamische Systeme darstellen, die zeitlichen Änderungen unterliegen. Dies wird am Beispiel der Erfurt-Formation in Nord-Württemberg gezeigt. Es lassen sich drei räumliche Bereiche identifizieren, die nebeneinanderliegen und unterschiedlichen Stadien der Aquifergenese entsprechen. Ausgehend von einem Geringleiter entwickelt sich ein gut durchlässiger und ergiebiger Grundwasserleiter, der mit Abnahme der Überdeckung und Verwitterung wieder zu einem Geringleiter wird. Das Beispiel zur Erfurt-Formation zeigt, dass hydrogeologisch verschiedene Bereiche, die heute räumlich nebeneinanderliegen, in einer Schichtstufenlandschaft aufeinanderfolgenden zeitlichen Stadien der Aquifergenese entsprechen. Dieses Modell zur Aquifergenese kann auch auf andere Grundwasserleiter übertragen werden und sollte bei der Charakterisierung eines Grundwasserleiters berücksichtigt werden.
