SCE PE Water Resources & Environmental study guide
SCE PE Water Resources & Environmental · Work through your exam, one topic at a time.
The Principles and Practice of Engineering (PE) exam is NCEES's discipline-specific licensure examination, described by NCEES as testing "a minimum level of competency in a particular engineering discipline." The Civil: Water Resources and Environmental exam is one of more than 20 PE exams NCEES offers and is designed for engineers who have gained a minimum of four years of post-college work experience in their chosen discipline. Content is quantitative and reference-driven rather than recall-based. The SCE PE Water Resources & Environmental study guide has 5 sections and about 1,542 words.
01Hydrology: Rainfall-Runoff, Frequency, and Routing
Hydrologic analysis starts with the water balance, P = ET + Q + ΔS + G. The highest-yield exam topics are rainfall-runoff, frequency analysis, and routing.

Apply the energy equation between sections: p1/γ + z1 + V1²/2g = p2/γ + z2 + V2²/2g + hL. The energy grade line includes velocity head; the hydraulic grade line is the EGL minus velocity head.
304 words, about 2 min03Open Channel Hydraulics: Manning, Critical Flow, and Jumps
Open channel flow is driven by gravity and bounded by a free surface. Manning's equation in US customary units is Q = (1.486/n) A R^(2/3) S^(1/2), where R = A/P is the hydraulic radius, not the depth.

A conventional train is coagulation, flocculation, sedimentation, filtration, and disinfection. Sedimentation design uses surface overflow rate (Q/A), which must be less than the settling velocity of the design particle.
273 words, about 1 min05Analysis and Design: Economics, Risk, and Design Criteria
Design decisions combine technical performance with cost, risk, and standards. Engineering economy compares alternatives using present worth, annual worth, future worth, or benefit-cost ratio.
