Coastal Flooding Assessment of Prince Edward Island using a 3D Model in QGIS

Introduction

With global warming becoming a concerning issue in the past three decades. This brings up the question of effects it has on geological, atmospheric and ocean processes. Human activities such as burning of fossil fuels, cutting down forest and farming livestock influences the climate and Earth's temperature. The result of global warming is an increased risk in natural disasters. The focus of the analysis is coastal flooding and area of interest(AOI) is Charlottetown, PEI(Prince Edward Island). Coastal flooding is a sudden and abrupt flow of coastal environment caused by a short-term increase in water level due to storm surge and extreme tides. It takes place when sea water flow over low-lying land that is normally dry and exist near the coast. Prince Edward Island is an area of interest because it is an island surrounded by Gulf of St.Lawrence and Northumberland Strait. It has an extensive coastline which makes it susceptible to coastal flooding and some areas of PEI are low in elevation which makes them vulnerable to the effects of sea level rise and storm surges.

The objective of the tutorial is to illustrate the effectiveness of a 3D map for coastal flood risk assessment along with important information that can be extracted from it.
