WebDec 28, 2016 · Time-lapse radar-tomography methods can monitor slug-injection saline tracer tests and image fluid flow paths in fractured-rock. Time-lapse cross-hole radar data sets were acquired at Mirror Lake by using controlled injections of fixed volumes of a high-concentration saline tracer, while scanning small sections of the tomographic image. WebJan 1, 2015 · Abstract. Traditional groundwater flow modelling is based on the Darcy's law which is valid when the flow is laminar. However, the water flow in fractured aquifers can be non-laminar in discontinuities and in this case the Darcy's law is not valid. That is why a numerical solver is needed which is able to model both laminar and non-laminar flows.
