Background & ProblemsHistory about Galveston and Seawall and Disaster
Main Problem is disaster: Hurricane & Storms, Flood & Tornadoes, Sea Level Rising, Dangerous Houston
Minor Problems: Energy, Drinking Water, Environmental Changing
Historical Storm Passages

Texas Coast historical storm passages direction analysis
➔ South-east
➔ Half of shoreline exposed under storm
➔ Galveston is under threatening
Main Problem is Disaster --- Storms & Hurricanes
➔ Category, intensity of hurricanes
➔ Cat 1 < 2 < 3 < 4 < 5
➔ Maximum sustained winds
➔ Devastating damage

➔ Nonrenewable Resources > 90%
➔ Renewable Resources < 10%
➔ Huge Improvement Space for Renewable Resources
http://instituteforenergyresearch.org/analysis/texas-an-energy-and-economic-analysis/
Renewable Energy Shortage
Texas Net Generation Shares Analysis
Minor Problem 1 --- Renewable Energy Utilize Rate is Low
➔ No Sources of Potable Water
➔ Water Supplies from Texas City.
➔ By Two Lines Attached to the Railroad Bridge in the Northeast
Portable Water Shortage

Minor Problem 2 --- Lack of Fresh Water Resource
Our SolutionCurrent Proposal
Our Proposal: Improvement on Existing Seawall, Extension Seawall Proposal, Floodgate Proposal
➔ Without proposal surge is 8 to 18 ft
➔ With proposal surge is 3-7 ft
https://coast.noaa.gov/hurricanes/index.html
Current Proposal
Modeling of hurricane surge before proposal
https://coast.noaa.gov/hurricanes/index.html
➔ Without proposal surge is 8 to 18 ft
➔ With proposal surge is 3-7 ft
Current Proposal
Modeling of hurricane surge after proposal
➔ Based on current proposal
➔ Improvements on Existing Seawall
➔ Extension Seawall Proposal
➔ Floodgate Proposal

Our Proposal
Proposal Diagram
Our Proposal Solution is also Seawall but We Have Solid Improvements on Existing General Idea
Drawbacks / Things to consider:
Area, usage, timeline, influx/ impact/ wave surges,
biodiversity of the site, other affected areas
downstream
Why we chose this strategy:
● Benefits outweigh the drawbacks
● Different types to be utilized in various locations
depending on ecosystem, qualities, and traits
Benefits:
● Prevent erosion in that area
● Protects inland, coastal defense
● Stops surges
● Can foster marine life
Analysis:● Usage of curved and mounds would be best
● Placement depending on land, surges, and
environmental impacts
● Enhance already built walls

Other ArgumentsEconomic Optimization
Tourism Industry
Population Forecast
➔ Various risk criteria: individual, social risk, economic
➔ Risk reduction benefits, and optimize level of protection
➔ Consequences: economic, life loss, environmental etc.
https://coast.noaa.gov/hurricanes/index.html
Economic OptimizationArgument 1: It is worth of cost
Safety Land Use and Cost Diagram
➔ Leading tourist destinations in the state.
➔ About 5.4 million tourists in 2007
Tourism IndustryArgument 2 --- Our proposal can increase economic value of tourism industry
https://coast.noaa.gov/hurricanes/index.html
Proposal Diagram
➔ Strong growth from 2005 to 2035
➔ 3.5 million residents in Houston-Galveston
➔ Over 100,000 new residents will move into Galveston County.
Population ForecastsArgument 3--- The population in Houston is increasing so that we need protect people from disaster
http://gulfcoastinstitute.org/2035_forecasts/main.html
➔ 14% growth rate in the past 10 years
➔ The remaining communities grow between 6% and 22%
➔ Hurricane Ike cause -7% & -5% in Bayou Vista and Tiki Island in 2007
Population Forecasts
