Mesures de debit et tracages. Manuel a l'usage des speleologues., 2001, Audra Ph.
This handbook provides some field method descriptions to cavers: discharge measurements (dilution method, weir...) and dye tracing (quantitative analysis, use of charcoal bags).

A dye-tracing investigation in the Poshte-Naz Karstic aquifer, Alburz Mountain, northern Iran, 2011, Kalantari N. , Mohammadi R.

The tracing technique has been recently used in karstified Zagros structural belt in northern Iran. A tracer study (uranine injection) was conducted in Jurassic limestone of the Poshte-Naz area in the Alborz belt to evaluate aquifer parameters and hydraulic relations between a large (about 100 m in diameter) sinkhole and springs. A main goal of the project was to find out the source of turbidity of the Emarate drinking water supply spring (SP4) in rainy seasons. Eight springs, three wells and the Neka River were selected for monitoring and totally 989 samples in 107 days were collected. In order to select reliable sampling stations, hydrochemical analysis of major ions was carried out and for better interpretation of concentration-time curve, spring discharge was also measured. The results of the tracing by sampling water indicated only a hydraulic connection between the injection point and the Sange-Nou spring (SP8) and, whereas the charcoal bags analysis revealed tracer exits also from spring SP1, SP3, SP4, SP5, SP8, in wells W1 and W2, and in the Neka River. This paper discuses concentration/time curves from charcoal bags for qualitative analysis and tracer exit curves for quantitative analysis.


Water tracing in the Muruk-Berenice system (Nakanai Mountains, New Britain, Papua New Guinea), 2011, Audra P. Hoblé, A F.

Three dye tracing have been carried out in the Nakanai Mountains to determine Berenice spring catchment area and some internal connections inside Muruk Cave. Andromede Cave belongs to Muruk-Berenice system, via Arcturus main drain. Due to special conditions in rainforest with difficult of moving, we made qualitative tracing using charcoal bags.


Towards a better knowledge of Cansiglio karst system (Italy): results of the first successful groundwater tracer test, 2011, Vincenzi Valentina, Riva Alberto, Rossetti Stefano

Cansiglio is a limestone plateau located on the border between the regions of Veneto and Friuli-Venezia Giulia, northeastern Italy. The eastern area is characterized by a thick succession of Cretaceous peritidal carbonates, while the central western part is characterized by slope breccia deposits. Even though Pian Cansiglio is an important karst system, its hydrogeology is poorly known. Three important springs that form the Livenza River are located at its southeastern border and are thought to represent the majority of karst aquifer discharge, but no experimental data are available in the literature. Gruppo Speleologico Ferrarese explored an 800 m deep cave (Abisso Col de la Rizza) on Pian Cansiglio, which provided the opportunity to conduct tracer tests. Fluorescent dyes were injected in September 2008 in Abisso Col de la Rizza (uranine) and in Bus della Genziana (tinopal CBS-X). Over a period of three months, local cavers conducted an intense sampling programme, which included collecting water samples, charcoal bags and cotton lints. Automated samplers were used for high frequency monitoring at two of the springs. Tinopal was not detected, so the connection between Bus della Genziana and the springs was not demonstrated. The connection between Abisso Col de la Rizza and two of the springs was demonstrated by uranine. A mean velocity of 248 m/day results from the tracer concentration peaks; intense rainfall events increased the flow velocities four to five times. Different hypotheses are considered in order to explain the low mass recovery rate (32-40% of the injected mass). The uranine tracer test demonstrated that Pian Cansiglio aquifer contributes to the two Livenza springs; it also opens a question about the third spring, which probably originates from the Mount Cavallo area (another limestone massif close to Pian
Cansiglio). The rapid response to rainfall recharge suggests a
vulnerability of the spring system, further supporting the importance
of conducting a detailed hydrogeological study
