As an academician, Dr. Chong has always believed that the young generation is the most important resource of the country, driving her advocacies for youth empowerment and training. Her primary interest is converting scientific knowledge into a non-scientific method that can be easily understood by the communities.
River Civilization and Disaster
A river civilization is an agricultural nation or civilization situated beside and drawing sustenance from a river. A river gives the inhabitants a reliable source of water for drinking and agriculture. Additional benefits include fishing, fertile soil due to annual flooding, and ease of transportation. The major rivers played a huge part in the development of early civilizations because the helped fertile the soil, which made it easier to grow crops. Rivers also helped separate civilizations. The land along rivers is is fertile. Animals can also be raised if there is enough food and water for them. People learned that they could stay in one place and grow enough food to feed their community, if they were near a water supply. The Kelantan River, located in the north-east of Peninsular Malaysia, is important and the only main discharge in Kelantan State. There are many residential areas, business centers, and infrastructure built along the river which are vulnerable to floods. Historical Records have shown extensive damages on the human environment cause by floods originating from the river.
The research attempted to create hazard maps of the Kelantan River Basin simulated in RRI model using ARIs at catchment level. In December 2014 due to extreme rainfall rate, flood even hit almost 90 percent of Kelantan State that cause much difficulty for residents. It is necessary to do flood forecasting to save both lives and property. Flood inundation models allow river discharge upstream to be related directly to flood extent downstream. The development of flood inundation maps is one of the primary non-structural method to understand the impact of floods within certain return periods to the inundation areas of one particular catchment. The inundation maps were developed using different methods and hydrological models, as such it is essential to compare the results of the various types of hazard maps using different periods to improve the existing flood management practices. This research uses the GEV frequency analyses and RRI model to visualize the inundated areas of floods with different return periods. This research benefits from the momentum of the unprecedented flood in 2014 in a view to proposing an updated inundation map.
Finally, findings from this reasearch are hoped to contribute to the current efforts in improving flood management in Kelantan River Catchment. Therefore, comprehensive planning can be made to ensure all the residents can be alerted and prepared for future flood incidents.
