Question 1

The Water Quality Index (WQI) for drinking water typically incorporates parameters such as:

Accepted Answer

pH, turbidity, dissolved oxygen, coliform, and heavy metals

Answer

WQI aggregates multiple parameters including pH, turbidity, DO, total coliforms, and chemical concentrations into a single composite score.

Question 2

In reinforced concrete design per ACI 318, the strength reduction factor φ for shear is:

Accepted Answer

0.75

Answer

ACI 318 specifies φ = 0.75 for shear and torsion, reflecting greater uncertainty in shear failure modes compared to flexure (φ = 0.90).

Question 3

Which geosynthetic material is primarily used to separate subgrade soils from aggregate base layers in road construction?

Accepted Answer

Geotextile

Answer

Geotextiles act as filters and separators, preventing fine subgrade particles from migrating into the aggregate base while allowing drainage.

Question 4

The concept of 'LID' (Low Impact Development) in stormwater management focuses on:

Accepted Answer

Mimicking pre-development hydrology through infiltration, retention, and evapotranspiration

Answer

LID replicates natural hydrologic processes using bioretention, green roofs, permeable pavement, and rain gardens to reduce runoff volume and peak flows.

Question 5

In highway geometric design, stopping sight distance (SSD) is most directly a function of:

Accepted Answer

Design speed, reaction time, and braking deceleration

Answer

SSD = vt + v²/(2a), combining the distance traveled during perception-reaction time and the braking distance based on vehicle speed and deceleration.
