6 HOMEWORK ASSIGNMENTS Course Syllabus (p. 2) Posted on the course website at least one week in advance of the specified due date. Due at the beginning of class on the day listed in schedule. Grades for late homework reduced by 10 points for each 24 hour period it is late. For full credit, all work must be shown do not just give the answer. Assignments must be neat, legible, and follow a logical order. Assignments not done on a computer must be submitted on engineering paper. No loose leaf, spiral notebook, or any other type of paper will be accepted. Students are encouraged to work together on homework problems, however, each student is required to submit his/her own solution for each problem set. 6

7 LABORATORY SESSIONS Course Syllabus (p. 3) Lab handouts will be posted on the course website at least one week in advance. Students are expected to download the handout and read through it before arriving in lab. Be sure to bring a copy of the handout to your lab session. In the first part of course, there will be 6 experimental labs in Dillman 110. Although work in groups during lab sessions, calculations and written lab reports are to be completed individually. In the second part of course, lab sessions will be used to explain tasks required for team project. Weekly memos and final project report to be completed as a team. Each lab report/memo due at start of your next scheduled lab session, unless otherwise indicated by TA or Dr. Webster. Lab TAs will provide additional details on format and grading of lab reports. (See lab syllabus) 7

Students are expected to read the lab handout prior to the start of lab. Attendance in your registered lab section is mandatory. Each lab report/memo will be due at the start of your next scheduled lab session, unless otherwise indicated. Grades for reports/memos submitted late will be reduced by 20% for each day late. All lab reports/memos must be prepared using a computer. More information will be provided by Lab TAs 10

11 EXAMS Course Syllabus (p. 3) There will be two in class mid term exams, each covering approximately 5 weeks of material, and a comprehensive final exam given during finals week. All exams will be closed book/notes. However, you may bring a one page crib sheet (8.5 x 11, front and back) to each mid term exam; two sheets may be brought to the final exam. There will be no make up exams. In the event of premeditated absences, for such reasons as universitysponsored activities or family emergency, Dr. Webster should be notified as early as possible. Exams may be given prior to absence. 11

13 WHAT IS WATER RESOURCES ENGINEERING? Control/management of water (CEE 3620) Movement of water through pipelines and channels Management of excess water (stormwater, flooding) Distribution of water for variety of purposes (CEE 5666) Water supply Industrial, municipal, agricultural Hydroelectric power generation Navigation Recreation Protection of water resources and environment Land use management (floodplain) Stream restoration, erosion control, dam removal (CEE 5665) 13

14 QUESTIONS TO BE ANSWERED IN DESIGN How much water is needed? (Hydraulics, pumping) How much water can be expected? (Hydrology, rainfall) What size structure is needed? Who may use the water? What kind of water is it? What structural problems exist? How is the natural environment affected? Is the project economically efficient and equitable? 14

15 ASSOCIATED DISCIPLINES Civil & Environmental Engineers Geologists Electrical & Mechanical Engineers Economists Political Scientists Chemists and Biologists Other natural and social scientists ** Other disciplines needed to fully address design questions, as well as to evaluate design alternatives based on cost vs. benefit analysis, environmental impact, etc. 15

16 VARIOUS TOPICS Hydrology (rainfall, runoff, evaporation, streamflow) Stormwater drainage Sewer/pipeline design Water distribution systems Groundwater Structures in water (dams, culverts, intakes) River flooding and sedimentation Watershed management 16

17 THE HYDROLOGIC CYCLE (NATURAL MOVEMENT OF WATER AROUND EARTH) Streamflow 17

18 STORMWATER DRAINAGE: SEWER SYSTEMS Controlled movement of water in urbanized areas Drain stormwater runoff (or reduce it) to prevent flooding 18

19 STORMWATER DRAINAGE: DETENTION BASINS Detain/slow runoff to reduce flooding Engineers help plan development and design pipe sizes and slopes, pond sizes, outlet structures, and vegetation. More detail in CEE 4640: Stormwater Management & Low Impact Development 19

20 SEWERS & PIPELINES Need pipes to carry away wastewater/stormwater runoff [sanitary, storm or combined] Need large pipes to carry water and oil long distances (e.g. Alaska pipeline). Engineers design pipe size, material, layout, route, supports, etc. 20

21 WATER SUPPLY & DISTRIBUTION SYSTEMS 21 More in CEE 4507: Water Distribution & Wastewater Collection Design

22 STRUCTURES IN WATER: DAMS/RESERVOIRS Dams provide for storage, water supply, flood control Can collect sediment and disrupt fish passage Design outlet structures (pipes, spillway) 22

23 STRUCTURES IN WATER: CULVERTS Culverts carry water under roads to prevent disruption of traffic or erosion. Engineers design opening, size, material, erosion control, fish passage. 23 More detail in CEE 4620: River & Floodplain Hydraulics

24 RIVER FLOODING AND SEDIMENTATION Predict if and when flooding will occur. Find required height of levee, size of culverts, bridges, etc. Determine when to evacuate people.

26 MISSISSIPPI RIVER, MEMPHIS, TN April 21, 2010 May 10, 2010 As water rises and overflows banks, observe change in flow dynamics and primary direction of flow. 28

27 HURRICANE IRENE VERMONT, AUGUST 2010 development had changed the landscape around rivers. By making them straighter and easier to build around, it meant that heavy rains turned them from placid waterways into chutes of destruction. Kendra Pierre-Louis,

28 FLOOD PREDICTION (HYDROLOGIC MODELING) Given measured rainfall values, predict magnitude of streamflow at watershed outlet (e.g. location of road crossing) 30

29 FLOOD MITIGATION Use hydrologic models to analyze impact of urbanization and/or channel modification on streamflow at watershed outlet (e.g. road crossing) Design structures to control/manage water 31 Water Resource Engineering, by Ralph A.
