การสร้างแผนที่น้ำท่วมถึงของแม่น้ำนครนายกด้วยฟรีแวร์และข้อมูลเปิด CREATING FLOOD INUNDATION MAPS OF NAKHON NAYOK RIVER BY FREEWARE AND OPEN DATA

Abstract

Flooding problems of Nakhon Nayok Province by Nakhon Nayok River often happen in Ongkharak district, especially on the area of Bang Luk Suea sub-district. For these problems, each local administration has not any maps to use as a tool for predicting where the inundation will take place, which is called as “flood inundation maps”. This study used freeware named Hec-Ras and open data to create flood inundation maps. It provides both pictures and animations. Because the local area data have not been enough, these developing maps were not calibrated yet. But in the future when such an amount of data increases, the maps will be more completed year by year.
