Applied of Geo-Informatics for analysis flood areas impact landuse A case Study Mun River Past 3/5 Subbasin

Abstract

This research is to study applied of geo-Informatics for analysis frequency of flood areas impact landuse in Mun river past 3/5 subbasin. Nowadays, it is the center of economy, society and environment of Ubon Ratchathani Province and Northeast. There are also many transport routes, causing growth and increase in urban areas which affect the area transformation. The study aims to analysis flood areas and verifying land use level 1 can also influence the frequency of flood. Except water area. The land use as a guideline for future urban’s growth.

The result reveals that flood areas in 14 times from the past from the years 2007 -2020. Forms of the frequency of flood impact areas are 187.3 square kilometers. Most of the affected areas were at the junction of the two rivers, Lam Sebai, flowing from the north, and the Mun River flowing from the east. The area in that area is a lowland area. When considering together with land use was found that the most affected areas were agricultural areas. And the least affected area is forest area. Especially in agricultural areas.
which have been adjusted to urban areas in the future. As well as from agricultural areas, miscellaneous areas and forest areas to urban areas. In addition, water areas along the Mun River that have also been developed into urban areas is prone to flooding.
