Note générale :	This chapter describes procedure for mesuring peak discharges using open-channel width contractions. Field and office procedures limited to this method are describes . This discharge equation based on the continuity and energy equation between an approach cross section and the contracted section under abridge of contraction is given. Contractions are classified into four geometric types . Discharge coefficients and computations procedures are given with a complete facsimile example of computation of a contracted-opening measurement. Additional procedure are given for multiple-opening contractions.
