Item The hydraulic design of irrigation channels for Ishapa, Kwara State, Nigeria(Department of Civil Engineering, University of Ilorin, Nigeria, 2010) Ajiboye, F.O.; Ayanshola, A.M.; Bilewu, S.O; Adeleke, O.O.; Salami, A.W.The artificial application of water to land to aid crop production has enabled man to increase his ability to produce food and cash crops. All – the – year round crop production is now possible instead of the previous restriction to rain fed agriculture. However, conserving water and delivery it to the fields in an efficient manner has continued to be a challenge. This work seeks to take advantage of a dam being constructed for water supply purposes at Isapa, Kwara State, Nigeria. The reservoir capacity is far too big for the water demand and therefore a large quantity of water will be available as excess. Incidentally, an expanse of fertile land exists in the immediate downstream of the dam which is suitable for irrigation agriculture. A detailed topographical survey was carried out among other studies and a layout was prepared for the delivery of water to the fields by the use of irrigation channels. Channel parameters were established through the use various tested formulas found in literature and from experience. It was also concluded that the reservoir capacity is adequate for both water supply and irrigated farm.
