The flow through an eroding dam is three-dimensional and exhibits several length scales. Laboratory experiments are fundamental to characterize these flows. Instrumentation and monitoring techniques in laboratory environment must be able to capture this complexity and scale amplitude and should be, preferentially, non-intrusive, particularly if the failure event is related with earth dams, where erosion patterns may be affected by instrument intrusiveness. Regarding embankment dam failures, the processes usually subjected to great scrutiny require the measurement of the breach effluent flow (BEF), the breach morphological evolution (through longitudinal and transversal profiles as well as 3D reconstructions) and the flow velocity over the dam and through the breach. This chapter presents advances in instrumentation to be deployed in dam breach laboratory tests and novel measuring methods made possible with such instrumentation. Emphasis is placed on the description of the critical components of the instruments, with emphasis on digital imagery, and on image analysis and post-processing techniques. A detailed exposition of existent methods, and respective evaluation of its suitability in the context of laboratory work, is presented.
