The Water Quality Index (WQI) for drinking water typically incorporates parameters such as:
Answer: pH, turbidity, dissolved oxygen, coliform, and heavy metals
WQI aggregates multiple parameters including pH, turbidity, DO, total coliforms, and chemical concentrations into a single composite score.
In reinforced concrete design per ACI 318, the strength reduction factor φ for shear is:
Answer: 0.75
ACI 318 specifies φ = 0.75 for shear and torsion, reflecting greater uncertainty in shear failure modes compared to flexure (φ = 0.90).
Which geosynthetic material is primarily used to separate subgrade soils from aggregate base layers in road construction?
Answer: Geotextile
Geotextiles act as filters and separators, preventing fine subgrade particles from migrating into the aggregate base while allowing drainage.
The concept of 'LID' (Low Impact Development) in stormwater management focuses on:
Answer: Mimicking pre-development hydrology through infiltration, retention, and evapotranspiration
LID replicates natural hydrologic processes using bioretention, green roofs, permeable pavement, and rain gardens to reduce runoff volume and peak flows.
In highway geometric design, stopping sight distance (SSD) is most directly a function of:
Answer: Design speed, reaction time, and braking deceleration
SSD = vt + v²/(2a), combining the distance traveled during perception-reaction time and the braking distance based on vehicle speed and deceleration.
Which type of foundation is most appropriate when a structure must transfer loads through weak surface soils to a deep bearing stratum?
Answer: Driven pile or drilled shaft
Deep foundations such as piles or drilled shafts bypass weak near-surface soils to mobilize end bearing or skin friction in competent deeper strata.
The 'method of sections' in truss analysis is most efficient when:
Answer: Solving for forces in only a few specific members
Cutting through no more than three members and applying equilibrium allows direct calculation of specific member forces without solving the entire truss.
