The Department of Irrigation and Drainage (JPS) of the Malaysian government has adopted an integrated approach to river basin development and flood management across the country. The major rivers of Peninsular Malaysia have their sources in the band of hills running along the centre of the peninsula. The country has a humid tropical climate; Average Annual Rainfall is 2500 mm, although seasonal distribution of rainfall varies widely from place to place. Many of the river basins have repeatedly suffered prolonged, significant flood events which have caused widespread disruption and impacts to residents, businesses and infrastructure. The impacts of flood events have been exacerbated by considerable rapid development over the past decade, which has modified the flow regimes and flooding mechanisms. To help prepare for, and mitigate, the effects of future floods, the Malaysian government, via JPS, is implementing a range of flood management projects, which will provide an integrated approach based on structural and non-structural measures. Flood forecasting and warning systems are currently being developed for key river basins. These systems are characterised by a need for flexibility in their handling of sources of incoming data, combining spatial and gauged observations, along with Numerical Weather Prediction (NWP) forecasts, as well as techniques for providing robustness to missing or poor quality inputs. The fully automated end-to-end systems are designed to ingest data, run simulations, and post-process results to provide flood managers and the general public with relevant information in a timely manner. Flexible dissemination routes via dedicated interfaces for operational staff, and websites, SMS messaging and smart phone applications for the general public, are designed to ensure that warnings reach stakeholders in time for action to be taken, so that the widely used government slogan ‘Rakyat didahulukan, pencapaian diutamakan’ (‘People first, performance now’) is key to resilient flood management.
