摘要

In the present study, aweekly operational planningmodel has been developed using a simulation technique for thenTambiraparani river systemin TamilNadu, India.Aplanningmodel has been developed incorporating the importantnfeatures of the existing operational policy. Paddy is the main crop cultivated in three seasons, although banana isncultivated to an appreciable extent, it has not been recognized in the existing operational policy. Themajor task of thenwater resourcesmanager is to find the area under paddy during the third season namely, the Advance Kar season. Thenmain objective of the present study is to simulate the temporal distribution of the available water in thenTambiraparani river system. Simulation is carried out for various possible extents of Advance Kar area and banananarea for various initial storage conditions. It is found that the entire Tambiraparani river system could be managednwithout deficit by reducing the release ofwater by 10–25%during the non-stress crop periods and also by lagging thenstarting period of the season by one or two weeks. If this management is practiced during average inflow years, it isnpossible tomaintain the same final storage as the initial storage during the start of the season. Thus the polices derivednusing the present study would be more useful to the system managers enabling them to authorize the area undernpaddy during the Advance Kar season and also to help them to maintain the required storage for the next season.
