Accurate discharge measurement is mandatory for any hydrological study. While the ?velocity? measurement method is adapted to laminar flows, the ?dilution? method is more appropriate for turbulent streams. As most low-gradient streams worldwide are neith...

Solute transport in rivers is controlled by mixing processes that occur over a wide spectrum of spatial and temporal scales. Deviations from the classic advection?dispersion model observed in tracer test studies are known to be generated by the temporary...

Tracer testing is the only method in karst hydrogeology that can definitively determine whether a particular site belongs to a watershed of a particular karst spring. Therefore, it is an essential technique for delineating groundwater basins in karst are...

Preferential flow is the most common form of water loss occurring at the interface between rock and soil (hereinafter referred to as ?rock?soil interface?) in karst areas, and it is also one of the important factors causing soil water leakage into the un...

A separate-bottom Couette cell is used to carry out ring-shear tests on sand and hydrate, and the evolution of shear bands is recognized using the tracer method. Based on experimental verification, a numerical simulation method is applied to study the sh...

Zerovalent iron nanoparticles (nZVI) are becoming one of the most widely recommended nanomaterials for soil and groundwater remediation. However, when nZVI are injected in the groundwater flow, the behavior (mobility, dispersion, distribution) is practic...

Tracer tests are widely used for characterizing hydrodynamics, from stream-scale to basin-wide scale. In karstic environments, the positioning of field fluorometers (or sampling) is mostly determined by the on-site configuration and setup difficulties. M...
