Abstract
The agricultural sector plays a key role in Sudan economy. It is well known that the Gezira Agricultural
Scheme is the largest irrigated area in Sudan, and largest area under one administration in the world. The
Gezira Scheme problem is that it suffered for several decades from political urgent decisions which led
to low production. This was associated with apparent destruction, degradation and poor irrigation. These
formidable problems revealed the main objective to solve the drawdown preventing development. This
extended the objectives which in turn revealed the existing conditions of the Gezira Scheme, checked
irrigation drainage infrastructures networks, water supply control, as well as released demands with its
impact on crops rotations and production.
The study methodology paved the road to keep the irrigation canals in perfect condition fulfilling the
entire objective leading to solution of all the problems. Field and office works can be successful if they
function with excellence during periods when there exists low water supply, such that the discharge in
the canals continue with optimum or close to the optimum design discharges two cases were considered,
Zananda and Haj Abdalla canals. The study indicated that renovation of such conditions is achieved with
such conditions. This was supplemented with the positive results of fieldwork practices inherited from
the past, associated with the high-level limits of the scientific recommendations. It is seen that Silts,
weeds in the canals are the most problems encountered with the scheme. In addition to mismanagement
of water discharge and crops rotations
