Abstract
The field experiments were conducted at Elrehab city, Cairo governorate, Egypt in
the winter season 2015 to evaluate the performance of the sprinkler irrigation system
under two different water qualities, treated waste water (TWW) and fresh water (FW)
and study the effects that influence the uniformity, water application efficiency,
precipitation rate, design and management of sprinkler irrigation system. The
sprinkler types were PS Ultra, PS, LPS, T5, Super 800, and NDJ. For the
determination of christiansen uniformity coefficient (CU), distribution uniformity
(DU), precipitation rate (Pr) and water application efficiency (Ea) . The results
showed that the rates of discharge of nozzle, the radius of throw and overlap for FW
were higher than the corresponding rates for TWW. It was observed that by
increasing the operating pressure, the precipitation rate was increased that was for all
sprinklers types. The study recommended using T5 sprinkler type under fresh water
influence at 450 kPa to give the best performance and the highest CU and DU values.
It recommended also using LPS sprinkler type under treated wastewater influence at
350 kPa to give the best performance and the highest CU and DU values.
