Reducing water turbidity is one of the main issues the water industryis currently experiencing. The ability to predict the spatial probabilityand intensity of discoloration events in distribution systems can leadto the adoption and improvement of proactive operation andmaintenance strategies to reduce turbidity. The main objective of thisstudy is to forecast Using the Prediction of Discoloration inDistribution Systems (PODDS model), simulate the turbidity responsein the Al-Saray water distribution network caused by higher flow ratesand a change in the daily demand pattern for water consumption. Thework covered AL -Saray water distribution network. with took intoaccount the two feed flowrate (FFR) values of the AL-Saray waternetwork, which were (522 and 5870) m3/day. The turbidity responsewas observed to be low when daily flows were supplied to thenetwork, but it increased as the flow increased. The maximumturbidity response was observed when water was fed into the Al-Saray water network at a flowrate of 5780 m3/day. the material layersare conditioned to daily flow, or shear stress. However, when the flowincreases due to an increased demand for water, the fluid's shearstress exceeds the material layers' shear strength, which leads to thematerial becoming mobilized
