Dye tracing is a valuable method to characterize fl ow in fractured-rock and karst aquifers. It is the method of choice for regional and intermediate fl ow measurements but can also be applied to some local measurements including the epikarst zone. In this chapter, we review some considerations for dye tracing, including types of dyes, along with sampling and analysis methods. A few examples are provided showing how dye tracing has been applied to answer some very specifi c questions including fl ow under a dam site, vulnerability of a cave habitat, confi rmation of contaminant source and evaluation of capture zones for a major spring. A special thanks to Tom Aley of the Ozark Underground Laboratory, who provided assistance with this chapter as well as project examples based upon his lengthy experience with dye tracing.

The scarcity of bathymetric studies in most Turkish lakes does not allow the documentation and the potential causes of lake bottom irregularities. In this study, relatively high-resolution bathymetric data from Lake Sünnet (NW Anatolia) revealed five deep (5.7 to 9.2m) and narrow (10 to 20m) depressions located along the boundary between the lake bottom and the steep lake margins. Analysis of lake level data belonging to dry seasons hints no leakage through these depressions. However, the negative conical shape and weakly developed levees around the holes suggest an upward episodic groundwater discharge for which direct evidence has been absent up to date. A combined hydraulic and soil mechanical model successfully explains the pockmark activity due to the flow of water through conduits in karstic carbonate bedrock. According to sedimentation rates and average depth of pockmarks in Lake Sünnet, and available regional paleoclimate studies, the onset of pockmark activity might coincide with the transition from the Near East Aridification Phase to the humid Beyşehir Occupation Phase around 300 BCE in SW and NW Anatolia.
