Evaluating Soil and Flood Conditions for Economical Flood Control of the Minanga River in Casiguran, Aurora

Natural disasters like floods have the power to obliterate people, things, and buildings. However, numerous flood mitigation strategies were developed to lessen their effects or to stop floods from destroying buildings, lives, and property. And many factors, including the flood and soil conditions, the cost, duration, and availability of the materials to be utilized in the structure, should not be overlooked while implementing flood mitigation measures. This would assist in determining the most cost-effective method of flood management for a particular area. In addition, the current study is focused on the Minanga River in Casiguran, Aurora. By assessing the soil and flood conditions, the cost and duration of construction, and the availability of materials, it was determined that concrete slope protection is the most cost-effective flood control solution for the area of interest. This is said to be the case because the soil is clayey and prone to shifting and spreading, necessitating the construction of a pile foundation to anchor the structure and provide concrete slope protection. The location requires this type of flood control, which can be relied upon to last long and far from failure based on the considerations that were examined, despite the estimates that the researchers’ work revealed to be that concrete slope protection is the costliest and longest length of construction.
