Tech Sis Interview Questions and Answers

Power house, spillway, headrace tunnels, and diversion tunnels are key components of a hydroelectric project.

• Power house is where electricity is generated using turbines driven by water flow.

• Spillway is used to control the release of water from the reservoir to prevent flooding.

• Headrace tunnels carry water from the reservoir to the power house.

• Diversion tunnels are used to divert water during construction or maintenance.

• Examples: Hoover Dam power house, Three Gorges Dam spill...read more

Dam walls are monitored using various instruments for safety purposes.

• Inclinometers are used to measure any movement or deformation in the dam wall.

• Piezometers are used to monitor water pressure within the dam structure.

• Seismometers are used to detect any seismic activity that could affect the dam's stability.

• Crack gauges are used to measure any cracks that may develop in the dam wall.

• Automated monitoring systems can provide real-time data on the dam's safety status.

Topographical survey is a detailed study of the natural and man-made features of a piece of land.

• Topographical survey involves mapping out the contours, elevation, and features of the land.

• It helps in determining the suitability of the land for construction projects.

• The survey provides valuable information for designing drainage systems, roads, and buildings.

• Topographical surveys are essential for creating accurate site plans and layouts.

• Advanced technologies like GPS and dro...read more

Dam safety monitoring involves regular inspections, instrumentation, and surveillance to ensure the structural integrity and functionality of dams.

• Regular inspections of the dam structure and surrounding areas are essential to identify any signs of distress or potential issues.

• Instrumentation such as piezometers, inclinometers, and crack gauges are used to monitor factors like water pressure, movement, and structural stability.

• Surveillance through remote sensing technologies ...read more

A spillway chute is a channel designed to safely convey excess water from a dam or reservoir.

• Spillway chutes are typically lined with concrete to prevent erosion.

• They are designed to handle high flow rates during periods of heavy rainfall or flooding.

• Spillway chutes may include features such as energy dissipators to reduce the velocity of the flowing water.

• Proper maintenance of spillway chutes is essential to ensure their effectiveness in managing water flow.

• Examples of spill...read more

There are three classes of rocks: igneous, sedimentary, and metamorphic.

• Igneous rocks are formed from the cooling and solidification of magma or lava, such as granite and basalt.

• Sedimentary rocks are formed from the accumulation and cementation of sediments, such as sandstone and limestone.

• Metamorphic rocks are formed from the alteration of existing rocks due to heat and pressure, such as marble and slate.
