In the present study, experiments were conducted to predict the influence of dry and wetness on aggradation and degradation in irrigation channels. The soil moisture characteristic curve (SMCC) of the experimental field was fitted with the retention curve (RETC) model to determine the soil hydraulic parameters. Soil dry and wetness significantly affected the sediments transport in irrigation channel. Erosion of sediments during the process of degradation was lesser under wet bed as compared to dry bed conditions, whereas, deposition of sediments during the process of aggradation was greater under wet bed as compared to dry bed conditions. Soil wetness reduced erosion and increased deposition of sediments in irrigation channels
