MHE 511 TUI Flood Damage Mitigation and Risk Reduction Analysis
INCIDENT COMMAND SYSTEM; PRINCIPLES AND FEATURES PART I; MITIGATION AND RISK REDUCTIONCase AssignmentYou live in Charleston, South Carolina, and your city has just experienced a widespread disaster caused by Hurricane Maxine. You have recently been designated by the city council and the city manager to determine if the city’s emergency response plan was effective in reducing property loss.Prepare a short plan to investigate the disaster and assess the flood damage in the city. Identify specific persons you will meet with during your investigation.You found that over 65% of properties in the low-lying areas were damaged and that there were no significant improvements in damage control since the last flood, which occurred seven years ago due to a failure of the levee system. List four reasons that may explain the apparent failure to implement an effective mitigation program. Adequately support your reasons for this apparent failure.Develop a recommendation that you would make concerning improvements in the city's mitigation plan based on the latest disaster experience.State and discuss the general principle in this case concerning the necessity and implementation of mitigation measures.Assignment ExpectationsLength: This Case Assignment should be at least 3-5 pages not counting the title page and references.References: At least two references should be included from academic sources (e.g., peer-reviewed journal articles). Required readings are included. Quoted material should not exceed 10% of the total paper (since the focus of these assignments is critical thinking). Use your own words and build on the ideas of others. When material is copied verbatim from external sources, it MUST be enclosed in quotes. The references should be cited within the text and listed at the end of the assignment in the References section (preferably in APA format).Organization: Subheadings should be used to organize your paper according to question.Grammar and Spelling: While no points are deducted for minor errors, assignments are expected to adhere to standard guidelines of grammar, spelling, punctuation, and sentence syntax. Points may be deducted if grammar and spelling impact clarity.

NOTE: Start from question 5 and do the tables below.Please use Basic English language/ Common language just like last time. Try to make your answers short and neat "no long answers because the professor will not approve" Table 1. Metric System: Length Measurement UnitsQuantityNumerical ValueEnglish EquivalentConverting to Metrickilometer (km)1,000 m1 km = 0.62 mile 1 mile = 1.609 kmmeter (m)100 cm1 m = 3.28 feet = 1.09 yard1 yard = 0.914 m1 foot = .305 mcentimeter (cm)0.01 m1cm = 0.394 inch1 foot = 30.5 cmmillimeter (mm)0.001 m 1 mm = 0.039 inch1 inch = 2.54 cmmicrometer (1 µm),also called a "micron (µ)"0.000001 m nanometer (nm),also called a"millimicron(mµ)"0.000000001 m angstrom (å)0.0000000001 m*Note: In other sources, you will sometimes see another unit, the nanometer (nm), used to measure wavelength. Each nanometer is equal to ten angstroms: for example, 7000 Å=700 nm. Although both the angstrom and the nanometer are used to measure wavelength, the nanometer is currently the more frequently used unit. Question 1. Using Table 1, complete the following:There are _________ centimeters (cm) in a meter (m).There are _________ millimeters (mm) in a meter (m).There are _________ micrometers (microns or µm) in a meter (m).There are _________ nanometers (nm) in a meter (m).There are _________ Angstroms (Å) in a meter (m).Question 5. In the space below, sketch your paper chromatogram using colored pencils. Then label the pigment bands with their respective pigments. Question 6. Based on how far it migrated, which pigment must have the greatest affinity for the chromatography solvent? Give the name of the pigment.Which must have the least affinity? Give the name of the pigment. Determining the Absorption Spectrum of the Leaf PigmentsAs light strikes a pigment, certain wavelengths will be reflected or transmitted, and some will be absorbed. Figure 3 shows a theoretical absorption spectrum. Figure 3. Theoretical Absorption Spectrums of Two Plant PigmentsQuestion 7. Generally speaking, which wavelength ranges and their corresponding colorsare most strongly absorbed by the pigments in Figure 3? (See your answer from Question 2.)Pigment:Ranges:Colors:Chlorophyll aChlorophyll b Question 8. Which wavelength ranges and corresponding colors are least absorbed?

Observed Absorption Spectrum for Grass Leaf PigmentsQuestion 9. On the graph above, at what two wavelength ranges do you see the "peaks" of light absorption? Label colors of light that are found in these two ranges, based on your answer from Question 2. Question 10.In what general range of wavelengths is absorption low?What colors of light are found in this range? Question 11.What happens to the light that is not absorbed in a solution? How does this relate to the fact that leaves appear green?What happens to the light that is not absorbed in the solutions we used in the spectrophotometers?Question 12. Although a plant’s leaf is its primary organ for photosynthesis, not all the cells in a leaf are photosynthetic. Observe the epidermal peel diagram on the bottom left side of Figure 5, as well as the model. Do all of the cells in the epidermal peel have chloroplasts? ____________ (Hint:Look for the cells that have chloroplasts in them! They appear as small, dark dots or ovals inside the cells drawn in Figure 5.) What is the name of the cells in the surface of the leaf that have chloroplasts? ___________________________________Now observe the diagram of the leaf cross section on the bottom right of Figure 5, as well as the model. Which cells have chloroplasts in this part of the leaf? ____________________________________Question 13. Observe the openings in the leaf’s epidermis in Figure 5 and on the model. What are they called? __________________________ If plants take in gaseous carbon dioxide (CO2) from the air and release oxygen (O2), how do the gases enter and leave the leaf? Question 14. Observe Figure 5 on the bottom right. Is the cellular material inside the leaf arranged so that the leaf is a solid mass, or are there spaces left inside?Question 15. If we could somehow remove the gases from a leaf without killing all the cells and then expose that leaf to sunlight, water and CO2 for a given amount of time, what gas would be produced that would refill the spaces within the leaf? ________________Question 16. Write the summary equation for photosynthesis:Question 17. How does your answer to Question 15 relate to your answer in Question 16?Let’s identify the components of the hypothesis. Question 18. What is the independent variable? (The one you will let vary in the different “treatment levels”)?Question 19. Name a dependent variable (or variables) (the variable(s) that you will measure to see if the Independent variable has an effect).Question 20. Now that you have the independent and dependent variables, create a hypothesis. Question 21. List the most important “controlled variables” (the ones that might wrongly affect your results if they are not “controlled.” These are also called confounding variables in the Understanding Experimental Design simulation). Question 22. Observe the leaf discs before vacuuming them: Are they now floating, or are they on the bottom of the flask? Table 3. Leaf Disc DataDistanceTeam Time (sec) TeamAll Teams NumberDisc 1Disc 2Disc 3AveragesAverage15 cm1 X 2XXXXX 3XXXXX 4XXXXX60 cm1 X 2XXXXX 3XXXXX 4XXXXX Question 23. According to your team's data, would you accept or reject your hypothesis regarding the effect of light intensity on photosynthetic rate? (Question 20) Describe exactly how your data lead to the above conclusion.Question 24. You also have data from all teams in your class. According to the class average from Table 3, would you accept or reject your hypothesis? Describe exactly how the data lead to the above conclusion.Question 25. If the class average data causes you to reject your hypothesis, present a new one in the space below. Question 26. Perhaps your data were inconclusive or even contrary to the class average. List some sources of experimental error which could cause a team's data to not fit the class average pattern:a.b.c.d.Question 27. Those who designed this laboratory exercise have tried to use certain procedures in the performance of the experiment to minimize experimental error or "control the variables." Identify some of those procedures:a.b.c.d. Question 28. Why have we used uniform discs and not whole leaves?Question 29. Examine the formula for sodium bicarbonate. What ingredient, essential for photosynthesis, does it provide to the leaf discs?
