The Task Committee on Experimental Uncertainty and Measurement Errors was formed to provide information and guidance on current practices used for describing and quantifying measurement errors and experimental uncertainty in field and laboratory hydraulic measurements. Hydraulic engineers in both practice and research measure a host of static and dynamic hydraulic variables including velocities, pressures, displacements, temperatures, fluxes, etc. Errors associated with these measurements arise from both systematic and random sources. Additionally, the measurement devices employed by hydraulic engineers are numerous, and often technically sophisticated. The Task Committee will produce a monograph which describes (1) sources of error in hydraulic measurements; (2) types of experimental uncertainty; and (3) procedures for quantifying error and uncertainty. The Task Committee welcomes the input from interested parties.
