The Potential of DNA-tagged Magnetic Silica Microparticle Tracers for Surface Water Tracer Hydrology: Using tracer injection experiments in the laboratory environment

Surface water tracing experiments help to identify the flow paths of in-stream mass transport. This provides useful information for developing mitigation measures for contamination, and thereby for solving environmental problems. Salts, fluorescent dyes and isotopes are commonly used tracer substances.<br/>However, it is well known these tracers...

Silica Particles with Encapsulated DNA and Magnetite as Hydrological Tracer: Magnetic Concentration and Proof-of-Concept

DNA has a number of characteristics which make it very promising as a hydrological tracer. It is detectable in extremely low quantities and can provide a virtually unlimited amount of unique tracers. The DNA tracer method has been further developed towards a multipurpose tracer combining a DNA tag, a paramagnetic core and a protective coating...

Using tracer data to calibrate a flexible, topography driven conceptual hydrological model

This study explores the possibility of calibrating a conceptual hydrological model to tracer (Oxygen-18) data measured in streamflow with the ultimate goal to predict discharge. The hypothesis is that (changes in) Oxygen-18 concentrations in the stream should tell something about the relative contribution of fast runoff compared to slow runoff ...
