dyetraceronderzoek
Dyetraceronderzoek, or dye-tracer research, is a method in environmental and fluid sciences that uses colored or fluorescent dyes to study transport and mixing in liquids and porous media. It is used in hydrogeology, river hydrology, soil science, and microfluidics.
A dye is released at a known location and time. Common tracers are fluorescein and rhodamine WT.
Data are analyzed as breakthrough curves to estimate velocity, dispersion, and residence time. Models range from
Applications include mapping groundwater flow paths and ages, characterizing river mixing, studying soil infiltration, and validating
Limitations include adsorption, degradation, and photobleaching, which can bias results. Non-conservative transport, scale effects, and environmental
Dye tracing has a long history in hydrology, with standardized tracer-test procedures developed internationally. Dyetraceronderzoek emphasizes
