The objective of the study search out elucidate the development of runoff, debris, soil C and nutrient fluxes using hierarchically reside catchments (micro-catchment accompanying plots in it, sub-catchment, catchment, substitute-basin and pan) over four years in the Thukela River basin, that is located in the orient of South Africa. Although the effects of soil deterioration, and the associated soil element (C) and nutrients, on the environment, are famous, there is still no accord on how the fluxes develop in a downstream course within river basins, on account of a lack of quality dossier in addition to many additional reasons. The results of the study showed a accepted decrease of the unit-extent runoff, soil, soil organic C and food losses as relating to space area raised from the plot to the basin scale. The styles of the fluxes were interpreted in terms of likely processes involved and the big controlling determinants. Deposition, infiltration and mineralization were respected as the key processes driving the observed currents. The intra-pool peaks were attributed to subversive water inputs, emerging land uses and conclusions. Restoration of vegetation and gully counterweight was recommended to combat soil, C and mineral losses.
