Droughts are a significant stressor for water supply systems and freshwater ecosystems. Studies on drought risks and impacts have focused on the frequency, duration, and severity of droughts. While these metrics may be appropriate for understanding the risks to consumptive water supply because they directly relate to deficits in catchment yields, they are insufficient to represent risks to ecosystems whose conditions are highly dependent on the sequencing of particular flow events. This paper explores the importance of differing sequences of wet and dry spells preceding and within a recorded drought period to water management objectives. A number of hydrological scenarios were developed by s..View full abstract

The majority of this research was funded by the Murray-Darling Basin Authority, and some financial support was provided by the Australian Research Council Linkage Project (LP130100174). Murray Peel is the recipient of an Australian Research Council Future Fellowship (FT120100130). The Murray-Darling Basin Authority and the Department of Environment, Land, Water and Planning (Victoria) provided access to the water resource models and data for this project. We would like to acknowledge the Authority staff for the time that they spent discussing modeling approaches and challenges for the project. The final form of this paper has greatly benefited from detailed comments provided by two anonymous reviewers.
