Abstract

In the arid area, analyzing water and heat balance is important for water management since most of water resource is supplied in the mountainous area. However, peak discharge analyzed by land surface model is earlier than observation. Therefore, in this study, several methods to improve modeling in the mountainous area were studied. First of all, “altitude mosaic scheme” was developed to consider mix of elevation bands in analyzing mesh. Water and heat balance were analyzed indepently, and they are summed with land cover fraction. Generally, mosaic scheme is used for land use, but elevation band was used since it is key component in mountainous area. Second, altitude dependency of meteorological data was discussed. Altitude dependency of long wave radiation and air humidity was discussed. As a result, analyzed peak discharge was improved and snow extinct day was validated by satellite analysis by MODIS.
