  17. WBS and Project Schedule • Gantt Chart

  18. Risk Management • Goal • To identify potential problems before they occur, control the risks if the risk occurs, and monitor potential risks during all phases of the project life cycle • Expected Risks • General Risks • - Environmental risk • - Unrealistically low bid • - Late-stage design changes • - Unexpected subsurface • conditions • - Settlement of adjacent structures • - Construction risk • - Technology risk • - Late materials delivery • - Climate and Weather risk • - Sabotage, terrorism and • theft risk

  19. Cost Estimate

  20. Feasibility Analysis (I) - Fixed Price per Energy : $0.11/kWh (1 year : $0.11*1,777,842 = $195,563) - Cost of Installing : $2,460,000 - Discount Rate : 0.03

  21. Feasibility Analysis (II) - Fixed Price per Energy : $0.11/kWh (1 year : $0.11*1,777,842 = $195,563) - Commercial Rates in FL : $0.0954/kWh (1 yr : $0.0954*1,777,842 = $169,606)

  22. Conclusion • Solar energy system is profitable to FIT and Provider • To get more profit • Reduce the installation cost • Increase the period of use of solar system • This course?

  23. Questions ?

  24. Introduction to Water Resources Prof. Thomas V. Belanger • Topic • Hydrologic Cycle • Water’s Properties • Precipitation • Evaporation • Infiltration • Surface Water • Ground Water

  25. Hydrologic Cycle Water evaporates Water vapour is carried up into the air Water vapour condenses to form clouds Rain water falls to form rivers Rivers flow into the sea

  26. How much water in the hydrosphere?

  27. Water’s Unique Properties • Hydrogen Bonding - Water’s unique properties comes from the strong attractive forces between oxygen and hydrogen molecule • High Heat of Evaporation • - Evaporation takes a lot of heat. This explains why sweating makes us feel cooler. • Great Dissolving Power • - Known as the universal solvent because so many things dissolve well in it. Leads to pollution problems as well.

  28. Water’s Unique Properties • Liquid over wide Temperature range - Without its high boiling point the oceans would have evaporated long ago. • Changes Temperature slowly • - High specific heat means slow temperature changes. Helps moderate climate. • Adhesion and Cohesion • - Strong forces of attraction between molecules allows water to rise up inside plants from roots to leaves. • Expands when it Freezes • - Most substances contract when frozen. Water expands and is less dense in its solid form. Hence, ice floats.

  29. Precipitation • Methods for determining the mean annual precipitation • - Arithmetic mean, Thiessen polygon, Isohyetal Thiessen polygon method Isohyetal method

  30. Precipitation • The resulting data

  31. Infiltration Process by which water on the ground surface enters the soil. • Ø Index method [Solution] ① Make a Hyetograph ② Estimate a Runoff depth 28.7 ac-ft/560 ac = 4.9 in. ③ Find the line level 2(1.4-Ø)+3(2.3-Ø)+2(1.1-Ø)+3(0.7-Ø)+2(0.3-Ø) = 4.9 ④ Find Ø by Trial and Error Assume Ø=1.5 → 2.4 in. of runoff. < 4.9 in. Assume Ø=0.5 → 9.0 in. of runoff. > 4.9 in. Assume Ø=1.0 → 4.9 in. of runoff. = 4.9 in. • [Example] • Watershed • : 560 acres • Runoff volume • : 228.7 ac-ft

  32. Surface Water water that does not infiltrate the ground or return to the atmosphere such as stream, river, lake, wetland or ocean. • SCS(Soil Conservation Service) Runoff method er [Example] Q) Assuming average hydrologic soils group C, Calculate the runoff volume for a 100 acre suburban development with the following land use if rainfall is 4 in.

  33. Surface Water [Solution] ① Find Curve Number ② CNw = (0.4x83)+(0.2x90) +(0.25x98)+(0.15x74) = 86.8 ③ SCS Runoff CN Method S=1000/CNw – 10 = 1.52 in. Q=(P-0.2S)²/(P+0.8S) = 2.62 in. ④ Runoff Volume = 100 acre x (2.62 in.) = 21.8 ac-ft

  34. Groundwater in Florida • Floridan Aquifer System • One of the highest producing aquifers in the world. • Found throughout FL and extends into the southern AL, GA, and SC • Sand and Gravel Aquifer • Primary source of water for western panhandle of FL. • Biscayne Aquifer System • Dade, Broward, and Palm Beach County. • Transported by pipeline to the Keys • Intermediate Aquifer System • Between SAS and FAS • Surficial Aquifer System • Any otherwise undefined aquifers that are present at land surface.

  35. Groundwater in Florida • Comprised of a sequence of limestone and dolomite • Thickness is from about 250 feet in Georgia to about 3000 feet in south Florida. • Floridan Aquifer System

  36. Problem Using Groundwater • Saltwater Intrusion - As water is pumped out of ground, saltwater can move inland to “pollute” the well.

  37. Conclusion • Saltwater Intrusion - As water is pumped out of ground, saltwater can move inland to “pollute” the well.
