Contribution of course to meeting the professional component

This course contributes primarily to the students' knowledge of engineering topics, and does provide design experience.

The following statement indicates which of the following considerations are included in this course: economic, environmental, ethical, political, societal, health and safety, manufacturability, sustainability.

Discussion of design elements includes issues on economical factors affecting design decisions, ability to protect the environment, and capability to construct the project (i.e., manufacturability). Ethical and political elements are discussed as they pertain to the engineer�s responsibility to the client and society. Emphasis is placed on the engineer�s inherent responsibility for the health and safety of the public.

Relationship of course to undergraduate degree program objectives and outcomes

This course serves students in a variety of engineering majors. The information below describes how the course contributes to the college's educational objectives.

This course relates to the primary objectives by providing thorough treatment of fluid flow in geologic media, application of mineralogical principles, and application of soil mechanics principles to engineering problems. Communication skills and professionalism are emphasized through preparation of construction specifications. Real-world principles are integrated through discussion of case histories and through the design process. Science, mathematics, and engineering are integrated through the design and analysis loop and through discussion of fundamental factors affecting flow and transport.

Assessment of student progress toward course objectives

Homework is assigned for each major topic in the course to assess the student�s comprehension of the principles and applications. Homeworks are graded and returned to students so they can assess and improve on their performance.
Three exams are conducted that cover all principles in the course. Exams include principles, applications, and design elements.
