A Simple Analytical Method to Assess Multiple-Priority Water Rights in Carryover Systems

Abstract

Simple analytical storage–reliability–yield relationships have traditionally only considered a single reliability for a single yield, yet many reservoirs supply water of different priorities. Simulation models may be used to handle such multiple-priority water rights but these models are complex and usually system specific. Here we propose a simple analytical method based on Gould-Dincer to estimate yields in dual and triple priority allocation systems from a carryover storage. This allows rapid assessment of changes in water resource availability for different water priorities, potentially over large spatial scales. We use a dam simulation model to assess this method at 15 sites across six ..
