Twenty-one cylinder infiltration tests were conducted during irrigation of wheat on the shrinking/swelling vertisol soils of Kafr El-Sheikh, Egypt. Infiltration rates decreased rapidly from 720 mm/ hr for the first minute to 7.2 mm/hr at 2 hours elapsed time, with 1/3 of the tests showing soil sealing. In the majority of tests a well-defined two phase cumulative infiltration curve was determined. Significant correlations of antecedent soil moisture content in the 0-100 mm and 0-200 mm soil depth at the phase change, and average infiltration rate during the first phase were found. The first phase of infiltration was considered to represent flow of water through the soil macropores in the drier upper layer and water through the soil macropores. The second phase represented vertical flow into the wetter lower soil layers and filling of the finite storage space above the high water table. The analysis indicated a design application depth for wheat of not less than 120 mm for the first irrigation and 55 mm for subsequent irrigations under prevailing Abu Raya irrigation practices. Good water distribution across the field was facilitated by low long-term infiltration rates and high water table conditions. With the low second phase infiltration rates, water ponded in field depressions for prolonged periods could be detrimental to crops and requires provision for surface drainage. Precision land levelling would reduce this hazard.

The management of surface-drained level basins, where a portion of the initially applied water is drained out from the inlet end of the irrigated basin, is reviewed. Design procedures regarding basin and channel layout, and land leveling are presented. Drainage is made possible by properly configuring of an earthen water supply channel relative to the basin surface. The proportion of drainable water from furrows (ratio of the volume drained from a furrow to the volume stored in the furrow at time of irrigation cutoff) ranged from 25% to 45% depending on the furrow length. Such drainage quantities would result in increased potential application efficiency. The utilization of the surface-drained level basin systems for rice production in rotation with other field crops is discussed.
