Forecast Interpretation

Abstract

Ensemble and deterministic flow forecasts provide information to support decision-making in a range of applications. However, to be operationally useful, forecasts need to be presented in terms which are meaningful to the end user and delivered in time to take effective action. Some tools which are used as part of this process include thresholds, decision support systems and risk-based techniques. This chapter describes the background to these approaches and provides examples for a range of flood warning, reservoir and other applications.
