The study is particularly evolves around the strategic ideas to tackle flood problem in the Maong river catchment area vis-ä-vis the development cycles that of the study area. In other words, both of the variables are in `direct relation' towards each other. It is based on the February 2003 flood event; refer to Appendix B. The February 2003 flood event flood is associated with a 20-years return period of rainfall. It is computed by using the recorded rainfall data from the Kuching Airport rainfall station. Plenty of areas in the upstream of the barrage were inundated during the event as well as some parts of the area in the Maong river catchment area. For that reason, the conceptual drainage improvement plans are generated. Among the proposed structures in this study are levees or flood walls, storage, tidal control device and pumping facilities. Several data collection and calculation processes will follow through in this project. Whereby, the computed value of Qp k by using the modified rational method is 263.58m3/s and estimated storm water volume to be stored is 2,851,200m3. The computed data will be used in the discussion section. This study is still in the identification stage of the stages in project planning. In addition, according to Carpenter (2002), "the protection of areas of floodplain reduces out of bank storage and changes the shape of the flood wave... potentially increasing flood risk downstream". In short, there is no total solution for flood problem.
