"No, it is not Bakhawan", declared Dr. Fernando Siringan that caused heavy flood in Kalibo, Aklan on June 21. Dr. Siringan is a noted Pilipino geological scientist. Dr. Siringan revealed his findings during a luncheon briefing followed by presscon held on August 28 at Bakhawan Eco Park, Buswang Old, Kalibo.
Through a multi media presentation, Dr. Siringan explained what were the causes of deep flood and mud in Kalibo and Numancia, Aklan. He showed that the flood and mud were caused by too much rainwater of 354 mm. on June 21. That quantity of water was more than 50 percent of the average rainfall of every month of June since 1998. That quantity of water has loosened the soil in the mountain which enhanced trees to collapse and landslides, hence soil erosion.
Another cause are the sand bars which impeded the flow of water in Aklan and Sooc rivers. According to Siringan, Aklan river is a braided river which has more than one water passages. These water passages change as soil, sand and silt are deposited as sandbars every time there is rain.
Moreover, the high tide of 1.8 meters on June 21 blocked the flow of water, hence deep flood as Kalibo is only two meters above sea level.
Dr. Siringan concluded, "Bakhawan mangrove in Kalibo has nothing to do with the mud and flood in Kalibo of June 21."
Dr. Siringan recommended for the dredging of Aklan river for flood control. He also suggested to conduct another geological survey to determine the elevation of Aklan for the future proper flood management. /MP
