Which instrument is widely used for surveying?
Which type of reinforcement are used in pre-stressing?
What will be the best method to calculate vertical stress of soil in geotechnical engineering ?
It depends on the condition of soil. Wt of dry soil +wt of water in soil + overlying Wt if any and so on. read the fallowing article in google for better idea. Vertical stress in the ground

So that, when you are tapping it, will level bed to set and air pocket will get out giving a level bed for bonding.

Meaning of Reinforced soil: Reinforced soil is simply a combination of compacted earth fill with the tensile reinforcement for creating an earth structure.
Advantages of reinforced soil:
- Less quantity of earth fill is required.
- The construction can be directly done on the soft ground.
- The structures can be quickly built as compared to any other conventional methods.
Limitations of reinforced soil:
- One of the biggest doubts about reinforcing soil is its durability.
Thank You.

What are the construction practices used to avoid differential settlement in foundation?
Differential settlement in foundation: Usually, due to poor compaction, lower bearing capacity of the soil, high depth of hard strata, various changes in water content in soil are the basic reason behind the differential settlement of soil.

Usually, due to poor compaction, lower bearing capacity of the soil, high depth of hard strata, various changes in water content in soil are the basic reason behind the differential settlement of soil.
Apart from that, trees & vegetation is not good for foundation safety.
Soil consolidation is the main reason for differential settlement of the foundation.
Foundation push piers & foundation underpinning also harms the foundation, which leads to a differential settlement.
Thank you.

Trapezoidal weir is also called Cipolletti weir, used for measuring medium discharge & is a combination of ▭ular & △ular weirs. The slope of the sides, inclined outwardly from the crest, should be 1 horizontal : 4 vertical (1H : 4V). The selected length of the notch (L) should be at least 3HRead more

Q = ⅔ Cd L √2g H3/2 + 8/15 Cd tan θ/2 √2g H5/2
If Q is lps, H in cm & L in cm.
Q = 0.0186L H3/2
