The R iver Yield Of The iver From the computed runoff 75% dependable yield of the basin is determined From flow duration curve75%dependable curve75%dependable yield of the basin=0.315M.cum

Computation Of Demand Crop water requirements in both both Kharif and Rabi seasons seasons are are computed by Modified Penman method. Monthly potential evapotranspiration at Arogyavaran Arogyavaran metrological station are used forcomputing the irrigation demand.

CONCLUSIONS



IT IS PROVOKED PROVOKED THAT IRRIGATION PROJECTS PROJECTS ARE ARE ASCERTAINED. THESE ARE HIGHLY VALUED PROJECTS , AND SPECIAL ATTRIBUTE KEEN INTEREST TAKEN BY GOVERNMENT IN CONVEYING WATER TO VILLAGES.



ATTRITUBE TO THIS , IRRIGATION PROJECTS ARE TIME DEPENDENT AND LESS FEASILBLE ECONOMICAL PROJECT , WE HAVE TO WORK UNDER VARIOUS PRESSURES.



REGRADELESS OF THE EFFORTS AND AMBIGUITIES TAKEN IN DOING THIS PROJECT, WE HAD THE PRIVILEGE OF DETAIL LEARNING AND EXPOSURE TO FIELD CONDITION.

ACKNOWLEDGEMENT



WE ARE THANKFUL TO TIRUPATI IRRIGATION DEPARTMENT , WHO HAVE GIVEN EMANCE INFORMATION IN PUT THIS T HIS PROJECT FORWARD



WE ARE DELIGHTED TO THANK PROF P.MALLIKARUJA P.MALLIKARUJAN N . WHO SPARED HIS VALUABLE VALUABLE GUIDELINES AND SPARED SPARED THIS VALUABLE VALUABLE TIME.



LAST BUT NOT LEAST , WE ARE EXTREMLY EXT REMLY HUMBLEMED TO EXPRESS OUR THANKS TO PROF ARUNA JOYTHI , WHO HELPED US IN ALL THE DIFFICULTS WHICH TEASED US WHILE EXCUTING THIS PROJECT
