Flood Hazard Risk Analysis with Remote Sensing and GIS/AHP

Learn how to make Flood Hazard Risk Analyse for any of the area in this world/ArcGIS Pro

Hello,

The weights and effects of 10 different layers were calculated for the Flood Risk Analysis with the AHP /multi criteria decision method with ArcGIS Pro. The use of Geographic Information Systems (GIS) and Remote Sensing in risk analysis studies are increasing day by day.

Geographic Information Systems are used to collect, process and analyze existing data in order to identify potential risk areas. In this study, Flood Risk Analysis   areas of the city of  Chennai district were determined by GIS techniques.

In the modeling phase, the Weighted Overlay Analysis method was applied and digital maps .

There are 6 sections and 36 videos. Totally, 5  hours 40 minutes!

Which analysis that we need?

Elevation,

Slope,

Topographic Wetness İndex

Curvature Analysis,

Precipitation Analysis (By using Schriber Method)

NDVI Analysis,

Landuse and Landcover Analysis,

Distance to stream Analysis/Proximity Analysis

Drainage Density Analysis

Geomorphology Analysis (Jennes Tools/I will provide this tool to you as freely)

You will learn from where to download and how the data to be used in the analysis,  what geographical processes it goes through and how it is prepared for analysis.

Raster and vector data how to be prepared one by one, projection conversion operations, adding fields and the shortcuts that will speed up your process when converting from raster to vector and from vector to raster will be especially useful for you. Based on this study, it has been prepared as a resource for you to do a similar study about any part of the world. By sharing the data I used throughout the study with you, I allow you to practice.
