摘要

The Taguibo watershed in Butuan City, Caraga Region, Mindanao, Philippines is the sole source of water for domestic, commercial, industrial and agricultural usage. For decades, the watershed had been supplying water to the city. Until now it provides clean and potable water to more than 200,000 individuals in Butuan City, however, as the City turned into a more urbanized community, the demand for sanitary water escalates while the number of supplier remains dormant resulting to intermittent water supply. To address this problem, this study identified possible sources of water for Butuan City by delineating watersheds within its proximity that could supplement the water demands. The identified watersheds and the Taguibo watershed were characterized to assess which of the newly identified watersheds possess similar or greater characteristics to Taguibo watershed. The watershed areas, river slopes, soil textures and curve numbers of the watersheds were the factors considered in identifying potential watersheds. The five identified watersheds along with Taguibo watershed were ranked according to their total weighted scores for each factor. The most suitable supplementary watershed among the five identified potential watersheds was Kolambugan watershed. Kolambugan has the largest area among the four candidates and is approximately three times larger than Taguibo watershed. It also has 100 % silt loam soil class which makes it more suitable to be a watershed. Kolambugan also has the smallest average curve number. Pianing watershed, on the other hand, was at the bottom of the rank since it has a small area, its soil texture is 80% clay and its average curve number is the highest among all the watersheds. With these results, the implementers would be guided on the possible watershed areas that could be explored to be another source of domestic water; which can greatly aid in Butuan City's problem of water supply.
