Floodplain Hazard Mapping in the Iranshahr River by Using Two-Dimensional Numerical Modelling and GIS

Today, the preparation of flood zoning maps is one of the basic and important issues in the study of development projects in the world; it is considered before any investment by the related organizations. In this paper, flood zoning was performed using the two-dimensional model HEC-RAS and GIS in order to assess the risk of the construction of a railway station near the bank of the Iranshahr Ri...

Comparison of classic and fuzzy analytic hierarchy processes for mapping the flood hazard of Birjand plain

Flood is one of the most destructive natural hazards which impose vast costs in order to compensate its effects, especially in areas where there are manifestations of human development (such as cities). Urban development, particularly in the margins of rivers, has increased flood damages in recent decades. The aim of this study was to develop flood hazard maps of Birjand plain based on analyses...

Probabilistic Prediction Models for Landslide Hazard Mapping

A joint conditional probability model is proposed to represent a measure of a future landslide hazard, and five estimation procedures for the model are presented. The distribution of past landslides was divided into two groups with respect to a fixed time. A training set consisting of the earlier landslides and the geographical information system-based multi-layer spatial data in the study area...

Recent Changes to the Hazard Mapping System

The Hazard Mapping System (HMS) was developed in 2001 by the National Oceanic and Atmospheric Administration’s (NOAA) National Environmental Satellite and Data Information Service (NESDIS) as an interactive tool to identify fires and the smoke emissions they produce over North America in an operational environment. The system utilizes 2 geostationary and 5 polar orbiting environmental satellite...
