The major improvement of this model compared with previous studies is the use of analytic solutions for reservoir releases in multireservoir systems. Furthermore, a GA search technique in the model is proposed to find a set of rule curves by different approaches in coding and decoding. A pilot application for Feitsui reservoir, Pinlin reservoir, Chihtan dam and Chingtan barrage is demonstrated to reveal the merits
