Visual interpretation of high-resolution satellite imageries to address failures of small stream irrigation weirs

Abstract

This paper introduces the availability of satellite image interpretation on the failures of irrigation weirs on a small stream in northeast Thailand. For the purposes, high resolution satellite imageries, QuickBird, were employed to carry out visual interpretations. As the results, the weir failures such as river side collapse due to obstructed flood flow and sedimentation on riverbeds can be identified. Through a series of image interpretations, the effectiveness of high-resolution satellite imagery for field science and investigation was confirmed. Also the possibilities were indicated that the actual status of agricultural facilities can be monitored remotely for maintenances and managements by using high resolution satellite imagery.
