Virus Infections and Diabetes Mellitust possible without irrigation. These two features, high rainfall intensity and irrigation, can lead to drainage problems specific to these areas. This chapter examines drainage design for erosion control in areas of high rainfall intensity and for the control of waterlogging and salinity in irrigated arid and semiarid areas.
