The distribution of soil moisture potential around emitters spaced 0.75 m apart along driplines buried beneath a crop of sugar cane was monitored throughout the growing season using arrays of mercury manometer tensiometers. The amount of irrigation to apply was determined using estimates of potential evaporation, and effective rainfall model, and crop factors. The potential measurements showed that a wet zone, bounded laterally by steep potential gradients, persisted below the emitter throughout the 5 month period studied. The size and form of the wet zone, or "wetted volume" varied diurnally and through the study period as a result of the sensitive dynamic equilibrium between irrigation, abstraction and drainage. The long term variations in size occurred when irrigation inputs did not exactly match the abstraction by the crop. The results indicate that abstraction by the crop must be taken a pre-determined proportion of the soil profile.

12 Hin-Fatt Cheong. 1992. Discharge coefficient of lateral diversion from trapezoidal channel. Water Resources Journal, March:56-64.
(Location: IWMI-HQ Call no: PER Record No: H012980)
The discharge coefficient of a lateral opening in a prismatic trapezoidal main channel is determined for subcritical flow conditions from considerations of the conservation of energy and the conservation of momentum. The latter requires an empirical relationship for the local downstream component of the spillage velocity with the local downstream velocity in the main part of the channel. The discharge coefficients obtained by both considerations for a broad range of Froude numbers, combination of both side slopes of IV:mH with m = 0, 0.5, 1.0, and 2.0, and different lengths of lateral opening are found to be nearly the same. The measured water depth just downstream of the lateral opening is not recommended for use in the numerical determination of the discharge coefficient and the reasons are discussed in detail. The discharge coefficient is found to be related to the upstream Froude number and this relationship is empirically established.

The approach towards the development of irrigated agriculture as a distinct and in time restricted intervention with predetermined objectives based on agronomic, technical and economic criteria must be abandoned for an open-ended approach to rural development, whereby irrigation is seen as one of the activities of the farm household and whereby the water user and the socio-political conditions constitute important criteria. The supposition that the design of the physical network must take into account wishes and demands of the water users regarding the use of the scheme make their participation a precondition for design. This asks for an interactive and iterative approach to the technical design and consequently the design assumes the nature of a process. Attention must be paid to the nature and structure of this process. In this article the author gives his vision on the consequences of the use of the scheme as the central focus for the design and the design process, based on his long field experience in Africa, the Near East and the Far East.

This paper discusses a possible solution for reconstruction of large systems aiming to take as much advantage from existing hydraulic structures as possible. An example presented here shows reconstruction of the "Nadela" drainage system into the system which can be used for both the irrigation and drainage. In order to evaluate as many alternatives as possible and to provide technically and financially appropriate solutions, designers applied a kind of the optimization procedure. The design followed these previous evaluations, it was precisely defined and easily carried out proving in advance that the resulting solution is suitable, especially from financial viewpoint.
