Coastal Applications Using ArcGIS Relating Land Use and Water Quality8-8 Introduction: Environmental Issues Overview There are several environmental concerns in Biscayne Bay: The channelization of this part of the state has lowered the freshwater table as much as four feet Freshwater flow into the bay has changed from sheet flows into intense point source flows, altering the salinity of different parts of the bay Development, especially in the northern part of the bay, has dramatically altered the natural flora and fauna

Coastal Applications Using ArcGIS Relating Land Use and Water Quality8-9 Introduction: Environmental Issues Overview Additional Environmental Concerns: Human use of the bay poses ongoing concerns like potential damage to coral reefs, destruction of seagrass beds, etc. Population growth threatens the mangrove forests that grow in desirable coastal areas Restoration projects like the Comprehensive Everglades Restoration Plan (CERP) might cause unforeseen problems

Coastal Applications Using ArcGIS Relating Land Use and Water Quality8-10 Exercise A: Brainstorm Data Background As part of the newly formed Biscayne Bay Project Coordination Team, your job is to determine what kinds of analyses are possible, given the technology you have access to, and what type of data you will need. Fortunately, your organization has been granted ESRI’s ArcGIS software for use in your conservation efforts. Your group needs to discuss the possible analyses that could be performed with GIS. The group also needs to think of possible data sets that might be useful. From these discussions, the group should develop a list of data that will be required to perform the tasks, as well as a “wish list” of data that you would like to have. Objectives 1.Discuss the possible analysis that could be performed looking at water quality and its link to land use 2.Discuss data that would be useful in completing these analysis tasks 3.Review available data and compare with your data wish list Goal After hearing the lecture and working through the exercises, the student will be able to address the issues surrounding data collection and application.

Coastal Applications Using ArcGIS Relating Land Use and Water Quality8-11 Exercise A: Brainstorm Data Group Discussion: What type of questions could the GIS help you answer about the relationship between water quality and land use around Biscayne Bay? Discuss and record data that would be necessary to complete the different GIS analyses discussed in your groups. Prioritize the data in your wish list. __________________________________________________________________________________ __________________________________________________________________________________ __________________________________________________________________________________ __________________________________________________________________________________ __________________________________________________________________________________ __________________________________________________________________________________ __________________________________________________________________________________ __________________________________________________________________________________

Coastal Applications Using ArcGIS Relating Land Use and Water Quality8-12 Demonstration: Available Data Your instructor will show some of the data sets that are available for use in your analyses. Do they differ from the data sets you came up with in your groups? If so, how? ___________________________________________________________________

Coastal Applications Using ArcGIS Relating Land Use and Water Quality8-13 Exercise Summary In this exercise, you were introduced to some of the history surrounding Biscayne Bay, Florida, in order to gain a better understanding of what it might be like to work for this community. In this module, you and your group discussed possible analyses you would want to perform with the GIS. With that in mind, you needed to think of possible data sets that would be required for these analyses. Once you developed your “wish list,” you were then able to compare it to actual available data for your area. Exercise A: Brainstorm Data

Coastal Applications Using ArcGIS Relating Land Use and Water Quality8-14 Discussion: Biscayne Bay Environmental Issues Water Pollution The geography of Biscayne Bay makes it a prime target for hurricanes and other major storms The possibility of several toxic releases into the bay in the event of flooding poses serious concerns Seagrass Degradation The natural seagrass beds of Biscayne Bay have suffered from several different types of stresses, including dredge and fill activities, urban development, navigation and change in salinity patterns due to channelization of the natural water flow

Coastal Applications Using ArcGIS Relating Land Use and Water Quality8-15 Exercise B: Choose Issue and Develop Analysis Background After reviewing the available data, the coordination team has asked your group to pick one of the identified issues to focus on. Once you have chosen an issue, your group will need to retrieve any pertinent data and examine them in detail to make sure they will work inside the GIS software. Your group will then need to create a flow diagram that outlines the steps you will take to address the issue facing you. After you have created a flowchart, you will implement your design by using the knowledge and skills gained throughout this course. Goal After hearing the lecture and working through the exercises, the students will be able to discuss the limitations of the available data and how they plan on completing the task with GIS. They will also be able to implement a flowchart and solve a problem using the tools found in ArcGIS. Objectives 1.Review available data and determine what manipulation might be needed to use them 2.Create a flowchart outlining the steps to take to complete the needed analysis 3.Solve a GIS problem using the skills, knowledge, and aptitude gained during this course

Coastal Applications Using ArcGIS Relating Land Use and Water Quality8-16 Exercise B: Choose Issue and Develop Analysis In small groups: 1.Choose an issue and review the appropriate data. You may choose to address one of the following issues: A.Seagrass – The natural seagrass beds of Biscayne Bay have suffered from several different types of stresses including dredge and fill activities, urban development, navigation, and change in salinity patterns due to channelization of the natural water flow. Use the available data to determine which seagrass beds are in danger of scarring from ships with drafts of six feet or more transiting marked navigation channels. Then create a layer that you will propose as a navigational Area To Be Avoided (ATBA). After you have completed your analysis, create a map that will convey your point to the coordination team. B.Pollution – The geography of Biscayne Bay makes it a prime target for hurricanes and other major storms. The possibility of several toxic releases into the bay in the event of flooding poses serious concerns. Use the available data to locate possible sites that might distribute toxic substances into the environment in the event of a 100-year flooding event. Generate a report listing the potential polluters and create a map indicating where these pollutants would enter the bay.
