Abstract: Several new hydrometric instruments and measurement techniques have been developed over the last few decades, but Hydrological Services 1, who have a responsibility to measure surface water characteristics, have not witnessed an equal growth in knowledge and practices pertaining to the standards for the use of the newer instruments and techniques nor for establishing the uncertainty associated with the estimate of the measurement. The World Meteorological Organization’s Commission for Hydrology in recognizing this deficiency identified at its Twelfth Session in 2004 the need “to develop a proposal and to implement a project to assess the performance of flow measurement instruments and techniques”. The proposed project is expected to improve the understanding of the accuracy of various types of hydrometric instruments, thereby contributing to the management of water resources. This paper provides the substance of the proposal and invites experts to come forward to contribute to this worthwhile initiative.
