Rainfall map precision in the watershed with missing data using precipitation and altitude gradient and p error layers of (case study: Taft-Dehshir catchment in Yazd province)
نویسندگان English
Sustainable management water resources in watershed need to study the status of the region. The precipitation is main parameters affecting all aspects of ecological, environmental and hydrological basins, so having adequate and accurate rainfall in order to watershed sustainable manage is essential. On the other hand shortage of sufficient rain gauge stations in the watershed and in some cases the lack of them, can reduce accuracy of research and studies results. Thus, the aim of this study is to provide accurate Isorain maps in Taft-Dehshir Basin. Taft-Dehshir basin is located in Yazd province and there are not enough meteorological stations in the basin. In this study, in order to preparing the rainfall map was used gradient height-precipitation method and with rain differences maps (error), Precision Isorain maps were produced. The results showed that using with precipitation and altitude gradient and taking into precipitation difference maps can provide very Precision Isorain maps in watersheds with missed and lacked data.
