Tracer Injection Experiments in RiveRs And Streams
River corridors, including their adjacent and underlying sediments, are ecosystems where waters from different sources mix. This mixing controls the fate of a multitude of dissolved solutes, such as nutrients essential to the ecosystem, dissolved minerals from natural weathering, pharmaceuticals from wastewater treatment plant discharge, and contaminants from nearby sources. Practically useful computer models of how solutes are transported, including how they are exchanged back and forth between riverbed sediments and the river itself, are needed to understand water quality in rivers.
Decades of river tracer studies, in one place
TIERRAS brings together tracer experiments from published studies, unpublished data and technical reports, curated into one consistent format so they can be compared and analyzed together.
AI-ready data
Train and test models that predict solute transport from simple site characteristics.
A common benchmark
Compare transport models and methods against the same real field experiments.
Better water quality decisions
Understand how nutrients and contaminants travel and are retained in rivers.
