The CCAM (GFDL) RCM simulated daily maximum/minimum temperature and rainfall datafor the base line period and future scenario for the IPCC SRES rcp 4.5 for 4 grid points (50kmx50km) falling in Aji basin were bias corrected using Probability Distribution Mapping adopting Gaussian and Gamma distribution respectively. The warming trend of annual average of daily minimum and maximum temperature from 1970-2005 to 2006-2070 was found increased from 0.027 o C year -1 to 0.04 o C year -1 and 0.027 o C year -1 to 0.025 o C year -1 respectively. The rainfall, runoff and groundwater recharge in the basin were found in statistically stable trend in Aji basin. The best probability distribution was used for estimating each water balance component. The crop water requirements during winter, summer and monsoon season may increase/decrease by the tune of 6.4%, -0.3% and 1.5% during winter, summer and monsoon season respectively in the future as compared to the past, due to climate change impacts. The monsoon seasonal rainfall will be decreased in the future due to climate change impacts. However, the extreme rainfall (100 year return period) event will be increased in the future by the tune of 39%. Similarly, the runoff will be decreased in the future but the extreme event (100 year return period) of runoff will be increased by the tune of 87.5%. The extremity (100 year return period) in the crop evapotranspiration and ground water recharge may be decreased by -5.7% and -5.8% respectively.

The study was undertaken to determine the performance of submersible pump and mono-block centrifugal pump to develop characteristic curves of and its operating conditions. The results revealed that submersible pump the maximum all over pump set efficiency was found 54.98 % at working head 40.43 m, discharge equal to 24.10 lps, WHP 12.99 and input HP 23.63, it was operating point of pump. More than 50 % efficiency can be achieved with discharge capacity varied between 24.10 to 17.89 lps. While Mono-block pump testing was done for suction lifts 0.5 m, 0.7 m, 1.6 m and 2.5m, the maximum efficiency was found 75.10 % at 0.7 m suction lift and at 29.34 m head under same static lift minimum efficiency was found 47.94 .So, operating head may be adopted 17 m against this head maximum efficiency is 48 %, discharge 11.9 lps and 5.5 HP
