Land-use data with a spatial resolution of 1 km are obtained from the thematic mapper images from 1990, which were classified into six categories based on the Technical Rules of Land Use Survey (Figure 6). There are six parameters responsible for the surface layer simulation, the values of which are listed in Table 2.
