Development of a decision support system for flood forecasting and warning – a case study on the Maribyrnong River
Floods are one of the most costly types of natural disasters in Australia and other parts of the world. It was reported that the average annual cost of flood damage in Australia was about $300 million as at 1994. However, the effects of flooding can be mitigated, and thereby reduce the loss of life …

NON-PARAMETRIC STATISTICAL APPROACH TO CORRECT SATELLITE RAINFALL DATA IN NEAR-REAL-TIME FOR RAIN BASED FLOOD NOWCASTING
Floods resulting from intense rainfall are one of the most disastrous hazards in many regions of the world since they contribute greatly to personal injury and to property damage mainly as a result of their ability to strike with little warning. The possibility to give an alert about a flooding …

Estudo de previsão de cheias em tempo real com modelos empíricos e semi-conceitual
Mathematical models are important parts in flood-forecasting systems. Usually empirical and semi-conceptual models are used independently. In order to minimize the errors induced by the independent use of the models, this dissertation suggests the simultaneous use of the two kinds of models. Three …
