Climate, Stream Flow Prediction and Water Management in Northeast Brazil: societal trends and forecast value

Kenneth Broad, Alexander Pfaff, Renzo Taddei, Sankar Arumugam, Upmanu Lall, Francisco Assis de Souza Filho Climatic Change (2007) 84:217–239 We assess the potential benefits from innovative forecasts of the stream flows that replenish reservoirs in the semi-arid state of Ceará, Brazil. Such forecasts have many potential applications. In Ceará, they matter for both water-allocation and […]
