N2  - Each measurement structure in open channels measure the water flow  with different performances and capabilities related to certain condition~ in the field. Most difficulties in flat land irrigation  systems are in choosing the appropriate measurement structure with the  limited head available.  A study of Broad-crested Weirs, Flumes, Orifices and Sharp- crested  Weirs has been done. The performance of structures related to accuracy  of measurement, sensitivity, siltation and entrapment of debris are also  studied. The sensitivity related to the shape and dimension of the  structure was calibrated in the Hydraulic Laboratory.  The descending structure types were found to be the most  appropriate: Flumes; Broad-crested Weirs; Orifices and Sharp-crested  Weirs
