tailieunhanh - Flood warning system over spatially predicted flood spreading area

The comparison shows that the accuracy of our hydrological river flow model is over 90% during flood peak time of raining season. Flooding has become a catastrophic disaster recently in many cities. Flood model based the satellite images, fuzzy logic evaluation, and water capacity sensors in river were studied while GIS has been applied to various applications. | Journal of Automation and Control Engineering Vol. 4, No. 2, April 2016 Flood Warning System over Spatially Predicted Flood Spreading Area Narongrit Waraporn, Panjaporn Truatmoraka, Suthasinee Sringenngam, Natchana Kucharoenpaisan, and Suthat Ronglong King Mongkut’s University of Technology Thonburi, Bangkok, Thailand Email: narongrit@, , miss_sangium@, sakuraja_jew@, suthat@ velocity. Satellite Synthetic Aperture Radar, SAR, image analysis was proposed by [1] in order to map the images in the spatiotemporal characteristics for flooding from river flow or as remote sensing for hydraulics flood model prediction [2]. SAR-based flood mapping has been extended in different approaches such as a near-real time flood detection called TerraSAR-X services [3] and an algorithm to clarify unclear SAR images [4] and camera images [5] from severe weather. Streams of water and canals gather into river. Original source of water streams and canal are waterfall, creek, and lake. Ref. [6] developed a risk index system for potential flash flood disaster risk assessment by applying fuzzy synthetic evaluation and spatial analysis to the river drainage networks with other earth science data such as soil moisture, vegetation, height deviation, and rainfall. Rain drops as a diverse type of sources of water. It should be included in the river model. Three locations of rain drop that increases the water level of the river are dropping into the river, dropping into the wet ground and dropping into the dry ground as shown in Fig. 1. Rain drop into the river increase the water level directly. Rain drop into the wet ground becomes the surface runoff which is more impact to flooding than rain drop into the river due to the larger area of land comparing with the area of river. Rain drop into the dry ground is much less impact to flooding because it remains into the ground for days before it becomes ground-water discharge.
