Introduction<\/h2>\n\n\n\n

This March the Hawaiian Islands saw higher than average rainfall and at a dam overflowed, rivers rose to historic heights, and there was major flooding in several communities. The Opaeula Stream<\/a> near Haleiwa on Oahu’s North Shore rose from 4 to 16 feet in one day. On Maui, the Kaupakalua Dam<\/a> was breached and caused evacuations and washed out streets. Additionally, the North Shore of Oahu, home to the world famous Banzai Pipeline wave break, has seen years of coastal erosion and elevated tides. Climate change affects sea level rise and the majority of Hawaii’s population live along or near the coast. I seek to calculate the total population of people who live in three major coastal flood zones across the islands. The following geographic visualizations are preliminary work for a more detailed final project. <\/p>\n\n\n\n

Inspiration<\/h2>\n\n\n\n

Response to the flooding on Maui and Oahu included anger at the local government for lack of oversight of potential flooding hazards. Hawaii is full of rivers, shown by the screenshot below in image 2<\/em>. On the mainland, New Orleans has been a focus of GIS and spatial analysis since Hurricane Katrina in 2005. There are many interesting maps the show the flooded areas, high risk area, and projected flood zones due to sea level rise and increased storm intensity. Images 3 and 4 <\/em>below are examples of those visualizations. Global sea level rise has already caused climate migrants and refugees to flee from their homelands. As the climate continues to warm, the ocean will continue to rise, putting more communities at risk of flooding and disappearing altogether (image 5<\/em>). <\/p>\n\n\n\n
