Discharge and sediment concentration were monitored at 2 dams, as well as gully erosion at 4 locations during 1988-1989 in the Shenchong experimental basin, located in subtropical Deqing County, Guangdong Province. Specifically, the objectives
of this study are : 1) to investigate the patterns of sediment transport and sediment sources in the research basin by considering the sediment concentration and discharge relationship ; 2) to assess the significance of gully erosion as a contributor to basin
sediment load by relating the basin response data to information obtained from the gullies in the basin.

Shenchong experimental basin is located in subtropical Deqing County, in the hilly granitic region of South China. The objectives of this paper are 1) to establish the seasonal water and sediment budgets of the experimental basin ; and 2
) to investigate the role of gullies as a source of basin runoff and sediment yield. The implications of these findings for basin management will also be explored.

Daily rainfall measurements and microclimatological theory are employed to construct a model of net rainfall, evaporation and surface runoff from north- and south-facing hillslopes in a small basin where soil erosion research was conducted. Soil
