Preview Questions Water Resources Engineer | Role Specific Skill

Question 1: What is the primary purpose of a sand filter in a water treatment plant?

Which action should you take?

Choose only one option

To remove suspended solids and particles from water

To reduce water hardness

To break down organic pollutants using microbial activity

To neutralize heavy metals

Question 2: What is the primary objective of floodplain mapping in water resources management?

Which action should you take?

Choose only one option

To measure the impact of flooding on agricultural productivity

To evaluate the water quality of the floodplain

To identify areas at risk of flooding and guide land-use decisions

To estimate the amount of water that can be stored in the floodplain

Question 3: What is the main assumption in the use of the HEC-HMS model for flood forecasting in watersheds?

Which action should you take?

Choose only one option

The river channel slope remains constant throughout the storm event

Infiltration rates are uniform throughout the watershed

Rainfall-runoff relationships remain constant over time

The watershed is homogenous with uniform precipitation distribution

Question 4: What is the primary purpose of a sedimentation tank in a water treatment plant?

Which action should you take?

Choose only one option

To allow heavier particles to settle out of the water

To increase the pH of the water to enhance coagulation

To increase the water temperature for further treatment

To provide additional filtration for fine particles

Question 5: What is the main difference between a perennial and an intermittent stream in hydrology?

Which action should you take?

Choose only one option

Perennial streams flow only during the wet season

Intermittent streams flow year-round, while perennial streams flow intermittently

Intermittent streams flow year-round with varying intensity

Perennial streams have continuous flow year-round; intermittent streams only flow during certain periods

Question 6: How should an EIA address the issue of water quality when assessing a proposed wastewater treatment facility?

Which action should you take?

Choose only one option

By comparing historical water quality data to future projections

By modeling effluent discharge concentrations and their impact on receiving waters

By analyzing the water chemistry of surrounding rivers and lakes

By estimating the potential for groundwater contamination
