Rapid saturation and flooding of paddy fields are essential for timely land preparation for the dry season (first season) crop when rice double cropping is adopted on flat lowland. Tertiary development was a priority project in the Muda area to facilitate water distribution and shorten the presaturation period by increasing the canal density. In order to evaluate the tertiary development properly, a simple method was devised for estimating the irrigation use efficiency and rainfall use efficiency.

In areas of low canal density, irrigation water may take a long time to reach its destination. This is due to the long distance involved between irrigation canals and drainage canals. Such low levels of irrigation canal density require high levels of water evaporation, meaning that the total water requirement under such conditions is large. In this study differences between areas with tertiary canal irrigation (Muda II project area) and those without tertiary canals (Muda I project area) were compared. Particular note was taken with regard to, first, the different progress of presaturation water and, second, the different amounts of water required under each type of irrigation condition. Two irrigation blocks with tertiary canal facilities and two without them were selected and compared from both coastal and inland areas in the first cropping season (dry season) of 1988, and the differences in the progress of presaturation water due to the differing levels of canal density and topographical gradients were noted. Water requirements were lower in the areas provided with tertiary irrigation facilities than in those without tertiary canals in both the coastal and inland areas.

Preliminary studies were conducted to test new design criteria incorporated in the Sefsafa Canal (SC) with the aim of reducing water application costs without sacrificing irrigation performance. For comparison, we also studied the Meet-Yazied Canal (MYC) (which is run without the new techniques). The cost-reduction measures used in this study included reduction of pump discharge rates and the use of electricity instead of diesel. We found that the location of farms along the irrigation canal had little effect on pump operation hours and amount of applied water; instead, crop patterns were the most important factor in this regard. The water use index (WUI), which is the ratio of applied water to required water, was higher in the SC than in the MYC and El-Mesk Canal (MC). Decreasing the pump discharge increased the amount of applied water to meet crop water requirements. During the winter, the WUI values of 1.11–1.16 achieved discharge rates of 70–80 l s-1 and were considered the optimal values of WUI. Further studies are required to avoid excessive application of water during the summer. The application of new techniques prompted farmers to irrigate their fields at night, thereby reducing water losses and installation and operational costs, and promoting equitable water distribution along the entire irrigation canal and throughout the command area.
