Abstract

ABSTRACT: Characteristics of suboptimal land, which is usually located in a river basin area, is strongly influenced by soil conditions, hydrology and climate, in which its management requires an integrated data assessment and utilization. In order to examine the climatic and hydrological conditions as well as the tidal effect in the Air Sugihan sub-river basin, a water balance analysis was conducted on the combined climatic data obtained from satellite remote sensing and in-situ monthly tidal data for a period of 2001-2013. The climatic data includes a monthly precipitation data, surface winds, surface temperature, surface, and subsurface runoff. The water balance analysis shows that the average total annual runoff occurring in the study area was about 87.7 mm/month or equal to 102.67 m3 /s. In addition, the water balance in the study area indicates an annual variation, in which the water deficit conditions are occurring in April to September with a peak during a dry season in August, while the surplus peak is occurring in November-December. However, the area is still experiencing a net annual surplus of about 302,468.81 m3 /month. Furthermore, the water balance conditions in the Air Sugihan sub-river basin are significantly correlated with the tidal fluctuations indicated by a coefficient correlation of r = 0.88
