| Abstract | The link canals network, constructed in 1960-70 in the Indus Basin Alluvial Plain of Pakistan to transfer of water from the Western rivers to the East, was designed at that time on the basis of the Lacey empirical regime theory. The Lacey theory was based on observations of existing irrigation canals. Departure of geometric and sediment transport characteristics from the designed parameters was observed when the link canals were operating. With the help of the equilibrium link canal data the behaviour of these canals to evaluate the applicability of the Lacey regime theory has been studied by different ways. Regression analysis between different parameters, analysis of the silt factor and analysis of coefficients for the Lacey relationships showed that they cannot be applied to the large link canals. Rather, the operational context and capacities play important roles. After applying the stability check given by Simon satisfactorily, the particular relationships of cross-sectional dimensions with the discharge have been given. These relationships alongwith the Lacey general velocity equation, which proved its effectiveness to this particular case, can safely be used for the design of such canals under the particular conditions described by the link canals data. |
