Support to the National Water Mission NAPCC Appendix 3 Kshipra Sub Basin SRTM 90 data. The DEM is used in basin and sub-basin delineation. A summary of the elevation statistics is given in Table 39. Table 39 Elevation Summary – Kshipra Basin Parameter Elevation (masl) Minimum Elevation 388 Maximum Elevation 831 Mean Elevation 510 186. Sub-basin delineation: ArcSWAT performs automatic delineation of watersheds using the DEM with a target outflow point selected interactively. The Kshipra river basin was delineated using 5,000 ha as minimum stream threshold. This resulted in 41 sub-basins. These sub-basins are shown in Figure 49. The basin area of the Kshipra up to the basin outflow point is 562,110 ha. Care was also taken to incorporate the locations of stream gauge measurement locations while undertaking the delineation process. 187. Land use/land cover is an important element of data that is required for pre-processing. The merged landuse and irrigation source map from IWMI, as shown in Figure 50, was used for the present study. IWMI derived the Ganges River Basin Irrigated Area product using MODIS 500-m and AVHRR 10-km satellite sensor data merged with IWMI‘s Global Map of Land Use/Land Cover Areas, to derive a new landuse map with agriculture landuse as well as sources of irrigation. The Kshipra basin is part of the Ganga basin. Land use categories and the area covered under each is summarised in 188. Table 40. The major part of the basin is under agriculture land use, and soyabean is the predominant crop. Figure 48: Digital Elevation Model of Kshipra Basin 83
