Présentation
From the study, it summarized that a significant LULC change was observed. The most important changes were substantial expansion of barren lands, agriculture and settlement lands whereas ; significant shrinking of water body’s, forest, shrub and grass lands during the analysis period since from the year 1973 to 2018. The SWAT model was calibrated and validated using long term records and obtained good model efficiency. The mean monthly stream flow simulations was increased during wet months and decreased in dry months. The base flow and ground water simulations were declined. However mean monthly simulations surface runoff was increased at wet seasons and decreased during dry seasons between the years 1985 to 2018 due to substantial LULC dynamics.
