Also, set “maximum distance” to allowable distance around hydrology network. Set “input feature source data” to results of “stream to feature,” and “Output Direction Raster” to desired name and location of processed raster.

Type and search “Euclidean Distance” from the geoprocessing toolbox.

The steps outlined below shows the use of Euclidean Distance in ArcGIS Pro

The tool will be used to draw a set distance from hydrology (river networks), which may be susceptible to floods.

The Euclidean Distance tool allows one to derive a set distance from a geometric feature (point, line, polygon), and also presents the output in a raster format. Also, set “input flow direction raster” to results of “flow direction,” and click “Run.” Set “Input Stream Raster” to the results of “stream order,” and “Output raster” to the desired storage name and location.

Type and search “stream to feature” from the search bar of the geoprocessing toolbox.

Also, set “Input flow direction raster” to the results of “flow direction.” Click “Run.” Set “Input Stream Raster” to the results of “Raster Calculator,” and “Output Raster” to the desired output name and location.

Type and search “stream order” from the search bar of the geoprocessing toolbox.

However, the following factors will be considered in this tutorial slope, hydrology, rainfall, and Land Cover.įigure 1 below shows a summary of the geo-spatial methodological tools employed in this tutorial. Many factors are considered during flood susceptibility analysis. This tutorial makes use of spatial data science and remote sensing techniques to assess the susceptibility of floods using ArcGIS Pro.

As a result, social interventions and government agencies have laid out effective urban planning strategies that would help mitigate the occurrence of the natural disaster (flood) that addresses Sustainable Development Goals and Green infrastructure. The prevalence of floods may be as a result of unusually high tides and storm surges, heavy rainfall, climate change, poor drainage system, melting snow or ice, among many others. One of the pressing issues in the world today that has led to loss of lives and properties, is the prevalence of floods. A flood is an overflow of water that submerges land that is usually dry.
