In this study, three mathematical models in the SIRMOD package including the hydrodynamic (HD), zero inertia (ZI), and kinematic wave (KW) models were tested using the data from several field experime...
畦田Philip入渗参数和田面综合糙率同步推求（Synchronously Determining Philip Infiltration Parameter and Synthesis Roughness Model of Border Irrigation）
畦灌 土壤入渗参数 田面综合糙率
2009/8/11
以水量平衡原理为基础，通过对畦灌地表水面线的概化，并将Philip入渗公式等同为α=0.5的Kostiakov修正模型，由此建立了利用畦灌水流推进过程同步推求Philip土壤入渗参数和田面综合糙率的模型。结合文献资料和大田试验对所建模型进行验证，并采用Matlab软件求解，得出不同地表储水形状系数σh下的入渗参数和糙率，并分别对入渗参数和田面综合糙率的可靠性进行了验证，结果表明所建模型同步推求土壤...
