Upper Waikato Dairy SWAM

Dr Tim Cox has developed a water allocation model for the Upper Waikato River catchment. The model was developed using the Simplified Water Allocation Model (SWAM) proprietary software. The objective of this work was to provide a tool to support decision making in the catchment with respect to hydrologic and water use planning and water consenting; and to provide for improved water accounting and data summarizing in the catchment. The model provides for a continuous extended simulation, on a monthly timestep, of the networked catchment system including critical drought conditions. It includes all major surface water users in the catchment, represented either discretely or in aggregation, with estimates of their monthly water use and return flows to the river.
