Flood Risk Indices Mapping of Lebak Regency, Banten Province

Mapping the flood-prone areas for developing a flood risk management system in the northeast of Iran

Comparison of spectrum indices for mapping soil salinity in saline lands of Chezan plain (Markazi province)

Soil salinity phenomena are one of the main problems of arid and semi-arid lands. Saline soils constitute a huge part of Iran, and also threaten its neighboring lands. Therefore, in order to optimum exploitation of such soils, qualitative monitoring is necessary. Recently, remote sensing techniques have been increasingly applied in monitoring soil characteristics. The present study was carried ...

Prompt Proxy Mapping of Flood Damaged Rice Fields Using MODIS-Derived Indices

Flood mapping, particularly hazard and risk mapping, is an imperative process and a fundamental part of emergency response and risk management. This paper aims to produce a flood risk proxy map of damaged rice fields over the whole of Bangladesh, where monsoon river floods are dominant and frequent, affecting over 80% of the total population. This proxy risk map was developed to meet the reques...

Flood risk mapping for Pari River incorporating sediment transport

Geographic Information Systems (GIS) are an efficient and interactive spatial decision support tool for flood risk analysis. This paper describes the development of ArcView GIS extension — namely AVHEC-6.avx — to integrate the HEC-6 hydraulic model within GIS environment. The extension was written in an Avenue Script language and Dialog Designer with a series of ‘point and click’ options. It ha...

Use of Remote Sensing and Gis for Flood Hazard Mapping in Chiang Mai Province, Northern Thailand

Throughout the human history floods have been an integral part of the civilization. Still men have not quite coped well to live with floods. Flood hazards result from a combination of physical exposure and human vulnerability to a geophysical process. Physical exposure reflects the type of flood events that can occur and their statistical pattern at a particular site while human vulnerability r...
