碩士 === 國立中興大學 === 土木工程學系 === 85 === The main purpose of this paper is to evaluate the influence of discharge and water level on drainage system when crops are changed in paddy field.And the diffusive tank model was advanced to simulate the drainage of low-lying basin of the field. The syudy bason that is a paddy field area(about 85ha)is in I-Lan. Another study bason os a rotational fiels area (about 275.4ha)is in Chia-Yi.And hydrologic stations were located in here to measure water stage and rainfall. The results of simulation show that the paramaters of paddy filed are cmu=0.25,B=1(m/ha) and the parameters of rotational field area are cmu=0.35,B=5.48( m/ha).On the other hand , the runoff intensity will be increasong 1.74 times of the oneoriginal when crop are changed on paddy field.
