To test the integrated approach, a typical agricultural watershed in Eastern China was selected as the case study area. This watershed has a total drainage area of approximately 122 km2, which is characterized by asymmetrical hills with a maximum elevation close to 1000 m (Fig. 1). In history, this watershed was covered mainly with natural forestland, but it has experienced an extensive agricultural reclamation since the 1980s. Currently, the dry farmland has occupied the largest watershed area, where wheat is the main crop being cultivated and rainfall, surface, and groundwater supply all irrigation water. As it is located in a hilly region, there are no obvious industrial point sources in this watershed. The watershed climate is continental monsoon, with the average annual temperature and rainfall of 13.2 °C and 790 mm, respectively. Local rivers are influenced by a seasonal hydrological regime, which generally flow from northeast to southwest.
