Study on the effects of the form of rainfall distribution model to the surface drainage regime in rice crop fields

Abstract

    Rain fall is a key factor that affects significantly to the drainage regime in rice crop fields. These factors are not only the amount of rainfall, the rule of rainfall distribution but also the forms of rainfall distribution model which perform crucially to this issue. Consequently, this artical will introduce research results on the definition of the design form of rainfall distribution model and its effects to the drainage regime in rice crop fields areas belong to Hanam province.
