Wetted front position is important in optimal drip irrigation system design. Wetted pattern depends on parameters such as emitter discharge, applied water volume, soil texture and structure and land slope. This field study was conducted in four slopes (0, 5, 15 and 25%) and 3 discharge rates (2, 4, and 8 lit/hr) in three application times (1, 2 and 4 hours). Soil texture was silt clay loam. Wetted pattern dimensions were measured by excavation sections parallel to the surface; moisture was measured in these sections 24 hours after finishing irrigation. It is recommended that if to Consider changing wetted pattern position in sloping lands and moisture distribution, emitter position toward plant has to be improved. This can be determined by the demonstrated equations.
