The study involves the following aspects:  (a) The study of the physical system and its socio-economic  boundaries.  (b) Study of the hydrologic processes of the system.  (c) Estimating the parameters for the management of the system.  (d) Formulating a chance constrained optimization model with  streamf low as a chance occurence.  (e) Testing the model to the real life data of the system.  (f) Conducting sensitivity analysis and suggesting alternate  management plans.  Linear prograrrming is used to solve the model for maximization of  net return from the study area. However, this study is a first attempt  towards the formulation of a scientific based decision making model to  facilitate decision support to the various agencies for this particular  system.  The study suggests that groundwater is not required for irrigation  purposes at 95% confidence level of streamflow. The terms confidence  level and reliability level are alternately used in order to define a  probability of occurrence of the event as has been used by Maji and  Heady (1978) . The net return can be maximized with proper management of  the resources. The sensitivity of the model to different changes  represents real life situation. The system has a great capability of  utilizing the available water resources. A 20% variation in input costs  do not affect the optimal agricultural planning. The system is capable  to handle critical dry periods with low precipitation and surface water  availability. 0aIrrigationxIndia1 aGupta, Ashim Das,eChairperson1 aBogardi, Janos J., eExamination Committee1 aNielsen, Steen Asger, eExamination Committee2 aFrance, eScholarhsip Donor2 aAsian Institute of Technology.tThesis ;vno.
