Abstract : The purpose of this research study is to determine the influence of soil type on the conditions of flood inundation heights that occurred in the city of Gorontalo through a grit-based approach to the study of spatial hydrogemorphology. Analysis technique using land units approach as mapping units. Based on the results of the study concluded that the city of Gorontalo, (1) Type of land located in the city of Gorontalo consists of two types of soil and soil alluvial soil hydromorphic grumosol. type of soil in the alluvial plains of the city of Gorontalo area of 3492.31 ha (98.55% of the plains town of Gorontalo) or 52.3% of the total area of the city of Gorontalo, (2) the results of the regression analysis (Chi Square Tests) mapping hydrogeomorphological units of Gorontalo, it is known that the characteristics of the potential danger of flooding is influenced by soil type, while to test directional measures have no effect because the real-lying city of Gorontalo is already a flood plain, (3) the infiltration rate is very slow in some areas of 0.0003 mm / sec according to Tsukamoto minimum of 2mm / sec. (4) high ground water level during the rainy season ranges from 0.5 m to 1.5 m.

Keywords : Type of Soil, Flood, Gorontalo City.
