Wyseure, 1992), as drainage does not generate more income, but simply aims to protect existing income, so farmers are reluctant to pay much to support such schemes. The drainage networks and suitable irrigation methods have to be considered when planning for a new cultivation in dry land to better control waterlogging and salinization hazard. It is highly recommended in this research that newly small and deep cut drainage canals network should be constructed and connected to the master drainage canal to dewater the excess irrigation water and to prevent
