  1. FROM SCENARIOS TO MANAGEMENT CLASSES: Water Resource System and Modelling Presented by: Pieter van Rooyen 26 November 2013

  2. Typical water resource system Stream Flow Reduction Small Dams Trout farming, recreation, dry-land agriculture Forestry Releases down river for irrigation, urban and industrial Large Dam Irrigation from canal Rural Rural: Subsistence, settlements Gorge, protected area Rural Nature Reserve Irrigation from river Town supplied directly from large dam Urban Industrial Estuary Treated wastewater

  3. Water Resource Modelling • Apply available hydrological data and models. • Refine model configuration to reflect relevant elements influencing the water balance. • Disaggregate network to represent flow at all Ecological Water Requirement Sites. • Prepare monthly time series data Natural, Present Day and for alternative scenarios. • Summarize information of time series: • Monthly distribution curves • Dam spill event statistics

  4. Scenario description

  5. Scenario description: Matrix
