Support to the National Water Mission NAPCC Appendix 3 Kshipra Sub Basin 3 C. Projects 3. There are three small dams on Kshipra as shown in Figure 4 and Table 1 summarises the details of the three medium scale projects Table 1 Medium Irrigation Projects Name District Potential Irrigated Area Year of created (ha) completion Sahibkhedi Ujjain 1440 984 1983 Kazikhedi Ujjain 1240 1366 1990 Dholavar Ratlam 6440 1353 Total 9120 3703 D. Climatic Norms, Kshipra Basin Figure 4: Project Locations 4. An assessment has been made of climatic norms in the Kshipra Basin using data for the station at Indore. The location of the stations is shown in Figure 2. In absence of meteorological data from the IMD at time for the preparation of this report, use was therefore made of the FAO CLIMWAT database1 which includes mean monthly meteorological data for over 5000 stations worldwide. 1 http://www.fao.org/nr/water/infores_databases_climwat.html
Support to the National Water Mission NAPCC Appendix 3 Kshipra Sub Basin 4 5. Figure 5 shows climatic norms for Indore and includes potential evapotranspiration and effective rainfall calculated using the FAO CROPWAT 8 package 2 . CROPWAT 8 uses the FAO Penman method in the calculation of ETo, and calculates effective rainfall using the USDA S.C. method. 6. Mean daily temperatures at Indore ranges from a low of about 18 o C in January to a high of about 32 o C in May. May and June are the hottest months with mean daily maximums close to 40 o C. The mean daily temperature range is typically about 15 o C. A maximum range of 15.5 o C occurs in May. The minimum range of about 8 o C occurs in July and August. Relative humidity is at its lowest in April, averaging 13%, and peaks in August at 87%. Wind speeds are generally in the range of 1.4 to 5.3 m/s, and are highest in May to June, when solar radiation is also at a its peak. The climatic parameters combine to give an annual potential evapotranspiration at Indore of 1943mm, with peak evapotranspiration in April, May and June. The peak daily rates of evapotranspiration occur in May with a mean of 11.2 mm/day. It is clear from Figure 6 that with the exception of the months of July, August and September, the effective precipitation is far short of potential evapotranspiration. Mean annual rainfall at Indore is 980mm, and the computed mean annual effective rainfall is 625mm.
