description | This study focuses on the study of hydrogeomorphology in mapping
vulnerability of flooding in Gorontalo City. flooded based on aspect of hydrology and
the aspect geomorphology in order to (1) examine the characteristics of potential flood
hazards by hydrogeomorphological mapping unit of Gorontalo City. (2) assess the
vulnerability of flood hydrogeomorphological mapping units and the relationship with
the level of vulnerability of hydrogeomorphological. (3) determine the
hydrogeomorphological zonation Gorontalo city flooded by the characteristics of the
causes of flooding, (4) formulate solutions and Gorontalo City flood control directives.
The method used is grid approach, it was to divide the land in Gorontalo City
to be 46 grids. Sampling data taking in every grid based on systimatic sampling
method, the results can be shown in tabulation/matrix. Data analysis using was to use
cross tabulation method, and then it was described.
The results of this study shows that: (1) analysis of variance showed that
overall the potential flood hazard and hydrogeomorphology variables have a
significant influenced. This is demonstrated by the significant value of 0% is less than
1%. Expectation value of the infiltration rate 66.7%, the rainfall rate 66,7%, the
drainage 33.3%, the landform 75% and the slope of 66.7%. Soil type not effective, (2)
the analysis of the level of vulnerability to hydrogeomorphological variables are very
significant. Flood affected area covering 965.828 ha (14.47%), evaluated the rate of
infiltration I4 and I5 covering 1744.33 ha. Rainfall causes flooding there are 4 types.
Poor drainage conditions (2097.64 Ha). F landforms is 3549.37Ha and D landform
area of 3121 Ha. The slope < 7% is 3507.84 Ha (52.6%). Aluvial soil type an area of
3492.31 Ha, (3) mapping of zone of flood hydrogeomorphology in Gorontalo city got
five classes of vulnerabilities are: Highly vulnerable (SR = 273.28 Ha), vulnerability
(R = 1023.339 Ha), vulnerable enough (CR = 2302,13 Ha), less vulnerable (KR =
168.77 Ha), not vulnerable (TR = 2781.95 Ha). (4) Based on the guidance
development polder drainage channels are divided into 3 (three) zoning, namely
western zone (1069.826 Ha) |
