Abstract

An automatic water management system for large-scale paddy fields has been developed. The purposes of that are to supply the paddy fields with water or drain water from that automatically, to decrease water consumption, and to have a good harvest. To accomplish the above purpose, developed system has five functions, (1) prediction of paddy growth stages, (2) water level control corresponding to growth stages, (3) estimation of mean water level, (4) prediction of water consumption, and (5) optimal water allocation for minimizing of damage. In this paper, we especially give a detail description of functions (3). For (3), we construct estimation model based on Kalman-filter theory, and give an estimation result.
