Abstract

This study aimed to determine the use of GIS (Geographic information Systems) in identifying the distribution of tidal overflow in the tidal area in Losari Lor Village, Losari District, Brebes Regency. The study used a mixed-method. The population in this study was the type of land use. The sampling technique used in this study was a total sampling area with 301.56 hectares of land-use area. The data were collected using observation, satellite image interpretation, and data documentation. The data in this study consisted of primary and secondary data which were analyzed using descriptive quantitative and qualitative methods. The results of this study on the use of GIS were presented using hydrotopographic spatial modeling. This modeling was chosen as an approach to compare the elevation of the altitude with the highest HHWL value in one year and the measurement results of the height value of the channel oveiflow from the ground swface. Hydrotopographic modeling would produce a tidal oveiflow zone map. The result of this study showed that the distribution of tidal ovetjlow in the case study area was identified to be spread over six types of land use covering an area of 124.18 hectares which was determined from the spatial data overlay of the tide oveiflow zone map with land use maps. In addition, the phenomenon of tides in the study area experienced the highest tidal oveiflow in a year from February to April or coincided with mangsa rendeng (rainy season) towards mangsa mareng (transition season).
