GTS and TBM benchmarks are both used in surveying, but GTS benchmarks are fixed points established by the government, while TBM benchmarks are temporary points set by the surveyor.
GTS benchmarks are permanent and established by the government for accurate and consistent surveying measurements.
TBM benchmarks are temporary and set by the surveyor for a specific project or survey.
GTS benchmarks are typically more accurate...
Connecting major schemes of irrigation to GTS benchmark is necessary for accurate measurement and monitoring of water levels and flow rates.
GTS benchmark provides a standardized reference point for measuring elevations and distances in the irrigation scheme.
Connecting to GTS benchmark ensures consistency and accuracy in data collection and analysis.
It allows for better monitoring of water levels, flow rates, and overal...
FRL stands for Full Reservoir Level and MWL stands for Maximum Water Level. FRL is the maximum level up to which a reservoir can be filled, while MWL is the highest level water can reach during a flood event.
FRL is the maximum level up to which a reservoir can be filled under normal operating conditions.
MWL is the highest level that water can reach during a flood event or extreme weather conditions.
FRL is determined ba...
Boulder toe, toe drains, and horizontal filter are provided in earthen dams to enhance stability and prevent erosion.
Boulder toe is placed at the base of the dam to protect against erosion from water flow.
Toe drains help in lowering the water table near the downstream toe of the dam, reducing uplift pressure.
Horizontal filters are used to prevent piping within the dam structure by allowing water to flow through while r
Balancing depth in canal refers to maintaining a uniform depth of water throughout the canal to ensure proper flow and prevent flooding.
Balancing depth is achieved by adjusting the cross-sectional area of the canal to match the required flow rate.
It involves designing the canal with the appropriate slope and dimensions to prevent water from pooling or flowing too quickly.
Proper balancing depth helps in efficient water ...
Water ratio in cement concrete mix is crucial for workability, strength, and durability of the concrete.
Water ratio affects the workability of the concrete mix - too much water can make it too fluid and difficult to work with, while too little water can make it too stiff.
The water-cement ratio also influences the strength and durability of the concrete - a lower water-cement ratio generally results in higher strength a...
Standard size of bricks is 190mm x 90mm x 90mm and tests are conducted by the quality control team at the work site.
Standard size of bricks is 190mm x 90mm x 90mm.
Tests are conducted by the quality control team at the work site to ensure the bricks meet the required standards.
Tests may include compressive strength test, water absorption test, efflorescence test, etc.
Quality control team may also check for dimensions, s
Standard thickness of inner and outer plaster in buildings varies depending on the type of construction and location.
Standard thickness of inner plaster is usually around 12mm to 15mm.
Standard thickness of outer plaster is typically around 20mm to 25mm.
Thickness may vary based on factors such as building material, climate, and structural requirements.
In earthquake-prone areas, thicker plaster may be used for added stre

ETP stands for Effluent Treatment Plant. Catchment and basin refer to areas where water is collected. Delta is a landform at the mouth of a river. Lintel and plinth levels are types of building levels. Different types of water loss in canal include seepage and evaporation. Span of a bridge is decided based on weight and width considerations. Zeta potential is a measure of the electrical charge of particles in a fluid.

To check palindrome and anagram of a string with O(n), use a hash table to store character frequencies.
Create a hash table to store the frequency of each character in the string.
For palindrome, check that no more than one character has an odd frequency.
For anagram, compare the hash tables of the two strings.
If the hash tables are equal, the strings are anagrams.
If the hash tables differ by only one character, the strin...

Bubble Sort is used to sort an array of non-negative integers in non-decreasing order by swapping adjacent elements if they are not in the correct order.
Iterate through the array and compare adjacent elements, swapping them if they are in the wrong order.
Repeat this process until the array is sorted in non-decreasing order.
Time complexity of Bubble Sort is O(n^2) in worst case.
Example: For input [6, 2, 8, 4, 10], the o

Find the shortest path between two houses in a city represented as an unweighted graph.
Use breadth-first search (BFS) algorithm to find the shortest path in an unweighted graph.
Start BFS from the source house and keep track of the shortest path to each house.
Once the destination house is reached, backtrack to find the shortest path.
Consider using a queue data structure to implement BFS efficiently.
