Title StatementFlood hazard mapping and vulnerability analysis of the coastal towns of Bataan along Manila Bay area by Ma. Cecilia A. Monteverde, Romeo M. Pelagio and Imelda I. Valeroso
Physical Descriptionviii, 112p. figures and tables
Summary, Etc.Flood hazard mapping and vulnerability analyses conducted in eight coastal towns of Bataan are presented. The main criteria used in the selection of the study areas, are their geographical location along the Manila Bay and existence of historical flooding. Thus, the focus of the study are the coastal towns namely, Hermosa, Abucay, Balanga, Limay, Samal, Orani, Orion and Pilar. The study aims to develop a database on flooding and vulnerability of these coastal towns in Bataan, and to evaluate the potential of flood occurrence. It also hopes to correlate the physical, social and economic conditions that make the area vulnerable to flooding, and lastly, to prepare flood hazard and vulnerability maps of these coastal towns in Bataan. Secondary data used include the historical data on flooding, barangay maps, topography or contour maps, soil maps, and hydrographic maps. The primary data consist of actual survey on flooding and on-site observation of recent flood events with still photographs taken in the study area. A simple hazard mapping method was used to delineate the flood prone areas. Analysis consists of defining the extent of flooding directly from the recorded inundation areas and data obtained from actual on-site surveys of recent flooding. In the absence of hydrologic and hydraulic data in Bataan, the evaluation was done by relating flooding to the primary physical characteristics of the coastal municipalities of Bataan using topographical and geographical information. In general terms, the results of the study indicate that the geographical extent and severity of flooding are affected by the geomorphology, physiography, water run-off, topography and inadequate drainage system. Specifically, the coastal towns namely, Hermosa, Abucay, Balanga, Samal, Orani, Orion and Pilar are most prone to flooding. The geographical delineation of flood vulnerable areas show that there are higly vulnerable to flooding as a consequence of their location in the lowland areas along the lower reaches of Manila de Bay. Furthermore, these places are densely populated with marginalized, vulnerable people. The agricultural lands, fish ponds and critical facilities or lifelines are located in the flood prone areas, hence making them highly vulnerable to disaster especially during the southwest monsoon season. Only the town of Limay has a very low susceptibility to flooding, due to higher elevation, being closer to the foot of the Mariveles Mountain
