CE 351 Water Resources Engineering

It is freaking cold out here. But we are not deterred (well some of us are not)

Water resources engineering involves the analysis and design of engineered systems that provide water of sufficient quantity and quality to meet the needs of humans and the environment upon which we depend. People have been doing water resources engineering for thousands of years, since water is such a fundamental need of society. The engineers that founded ASCE in 1852 had just completed work on a large water project, the Croton Aqueduct, a tunnel that first brought water to New York City. Water resources issues affect other branches of civil engineering, such as the design of roadways and bridges. For example, the erosion of bridge foundations by flowing water is the most common cause of highway bridge failures.

The course is based on the fundamentals of fluid mechanics previously learned in CE 251, hydrology (i.e., the science of water movement), and a bit of statistics and probability related to the concept of risk and probability (e.g., “the 100-yr flood”) that is central to water resources design. The course is divided into three main sections: Water Distribution Systems, Open Channel Flow, and Hydrology & sustainable* (see footnote) Stormwater Management. Ground water is not a main focus since there are other courses at Lafayette on that topic (GEOL 210, CE 424). Weekly laboratories include lab experiments in hydraulics, computer analysis, and field studies.

Large water resources projects, such as the New York City water system, or management of flow within the Delaware River (basin map), or even operations of an individual reservoir often have multiple objectives and “stake-holders”, as well as significant political, social, and environmental implications. Here in the Lehigh Valley, over the past decade no issues in water resources have been bigger than fracking and flooding. We will view several movies, discuss current news stories, and take a field trip to explore such issues.
