PERFORMANCE OF BAFFLE-SLUICE MODULES WITH CHANGED MODULE DIMENSIONS

An irrigation module delivers nearly constant discharge irrespective o f water-level fluctuations in the supply channel. Low discharge baffle -sluice modules have been designed for the field outlets considering d ie desirable features of a good module. The Row-regulating characteris tics of three baffle-sluice modules with the option of reduced module width and baffle heights are discussed in detail, The modules are foun d to deliver discharges within +/-5% of the design value in a modular range of 10 cm. Thus the concept of baffle-sluice modules already conc eived and designed can contribute to the modernization of water manage ment systems in supplying the requisite amounts of irrigation water de pending on crop requirements.
