The overall objective of this research is to develop and demonstrate methods for operational forecasting of water related hazards in developing cities, considering hazards at different spatial and temporal scales, posing a threat to inhabitants and property in the form of flood waters, debris flows, and water of poor quality. Key to the objectives of the research is that methods developed need to be reliable so that the decision makers who interpret the information provided by the model can understand how to use the guidance provided to warn those at risk, or for implementing risk mitigating strategies. Also methods need to be robust to use in the operational forecast environment, robust to the data scarce environment, and robust to anthropogenic and long term climatic changes. The specific objectives of the project are: - To establish reliable methods for identifying water related hazards at different scales in developing cities, including hazards due to slow onset flooding, flash floods, debris flows and pollution. - To investigate the reliability of observed and forecast rainfall at different scales, and provide methods for combining available rainfall information for improving reliability of forecasts at longer lead times. - To establish modelling approaches that can provide insight and guidance to the forecaster for water related hazards at different scales, with these approaches being robust to data poor environments. - To investigate if available data from freely available remotely sensed sources can provide reliable data at appropriate scales. - To use hydro-meteorological forecasts in operation of drainage and sewage networks to minimize outfall of poor quality water on to the streets and in to receiving waters.
