Grading - Two hourly exams 17.5% each Homework 17.5% HECRAS and HECHMS Projects 17.5% each WDS design project 12.5%

CE 527 - The additional effort required for those enrolled for graduate credit is to independently apply a hydraulics program. UNET (within HECRAS), EPANET water quality analysis, and KINEROS (USDA kinematic wave erosion model) are examples. It will count for 12.5% of your grade and the other components will be reduced proportionally. See me regarding the scope of your application.

Letter grades will be assigned as follows; >90% A 80-90% B 70-80% C 60-70% D <60% F Homework is considered late if not turned in the day due and no credit will be given for late homework unless prior arrangement has been made with the instructor. Course Objectives - This course is intended to introduce students to water resources engineering design. This is accomplished by learning the principles behind and applying several widely used computer programs. The models will be used extensively to perform sensitivity analysis and to design several real-world systems.

Course Projects – Three course projects will be completed. The EPANET projects will be completed independently. A written report from each project will be typed in a professional format (double spaced). They will include a description of the system, a brief review of theory, some discussion of the individual's design process (how you got to where you got), description of the final design and alternatives, and references.

Course Topics Topic (computer model, author) Water Distribution System Analysis (EPANET and H20Net, USEPA) (3 weeks) Backwater Analysis (HECRAS, USACE) (5 weeks) Flood Hydrograph Analysis (HEC-HMS, USACE) (5 weeks) Stormwater modeling (EPASWMM and InfoSWMM) (if time permits)

To introduce material the sequence for each topic follows the framework below. 1. Introduce purpose and utility of tasks and basic program capabilities 2. Introduce data structure for input with emphasis on understanding the needs and how to acquire information. 3. Review theory 4. Simple system analysis to acquaint student with input and output. Applications continue through each unit. 5. Complete review of theory and data needs. The focus in is understanding importance of data, where to find it, and interpreting results. 6. Sensitivity analysis to see impact on model results. 7. Design or major analysis project with report.
