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