Dyed water moves through porous material within a laboratory scale sand tank in this video. Dye is introduced at tubes representing wells and moves with the groundwater to an outlet tube representing a stream. A duration of 30 minutes of flow is compressed to 1 minute of video. The sand tank was constructed by students at the University of Wisconsin, Stevens Point, Wisconsin, USA. The dye movement was filmed at the Integrated Groundwater Modeling Center of the Colorado School of Mines in Golden Colorado USA. (2 minutes)
A discussion of the material in this video is provided in Section 1 ‘Introduction’ of the Groundwater Project book ‘Graphical Construction of Groundwater Flow Nets’, the PDF can be downloaded or the online version can be read at that link.
