CT5510. Master course on design and planning of the urban water management system. It deals with fluxes and processes in water and soil. Furthermore, aspects of water management policy development are discussed. Lecture on rainfall-runoff relations. Because it is impossible to handle all processes which influence the runoff of precipitation, simplified models are used in design and operation of urban water management systems. These models use different computation methods to convert precipitation into net precipitation (loss models) and net precipitation into design runoff (transformation models).
