Australia had already sealed their place in the final. Sri Lanka was defeated by New Zealand, after which the Indian team's place in the final was confirmed. The WTC 2023 Final match between India and Australia will be played from 7-11 June 2023 at...

WBM Road (Water Bound Macadam Road):- WBM road stands for Water Bound Macadam Road. It is a type of road construction where coarse aggregate is laid in layers and compacted with water. The interlocking of the aggregates provides stability and durability to the road. WBM roads are commonly used in rural areas and low-traffic urban areas. They are cost-effective and require less maintenance as compared to other types of roads. Material Required For WBM Road Construction:- 1. Stones : Stones of different sizes ranging from 90 to 150 mm are used for the construction of WBM roads. These stones should be hard, durable and weather-resistant. 2. Coarse Aggregates : Coarse aggregates including crushed stones, gravel, and various types of rock are needed for the base layer of WBM roads. They provide strength, stability, and resistance against erosion and traffic loads. The properties of coarse aggregate for water bound macadam road include: i. Strength : The aggregate should have sufficient stre...

What is lysimeter? Lysimeter Lysimeter is a system used to measure the water lost through evapotranspiration by plants in a given area. It consists of a large sealed container that is filled with soil and planted with vegetation. The lysimeter is equipped with sensors that measure the amount of water entering and leaving the system through precipitation, drainage, and plant transpiration. By measuring the water balance in the system, researchers can determine the amount of evapotranspiration occurring in the area. This information can be used in a wide range of applications, such as agriculture, hydrology, and environmental monitoring. Lysimeter uses:- Lysimeters are used to simulate and measure the water balance of soils and vegetation. They can be used for a variety of applications, including: 1. Estimating evapotranspiration rates of crops and other vegetation 2. Determining the effects of various management practices on soil water and solute movement 3. Quantifying nutrient leachin...

 What is a fathometer? A fathometer is an instrument used to measure the depth of a body of water, usually the ocean. It works by sending sound waves from the device to the seafloor, and then measuring the time it takes for the sound waves to reflect back to the device. This time interval is then used to calculate the distance to the seafloor, and thus the depth of the water. Fathometers are commonly used in marine navigation and exploration. A fathometer (also known as a depth sounder or sonar) is an electronic device used to measure the depth of water. F athometer is a crucial instrument for safe navigation in water bodies, and it is commonly used by commercial and recreational boaters to ensure that they avoid underwater obstacles and stay in safe depths. Fathometer Types of fathometers: - There are several types of fathometers, including: 1. Echo sounders : The most common type of fathometer that sends a sound wave to the seabed and measures the time it takes for the wave ...

What is planimeter in surveying? A planimeter is a mechanical device that is used to measure the area of an irregularly shaped two-dimensional object. It consists of a flat plate that is connected to a measuring wheel by a linkage arm. To use a planimeter, the plate is placed on the surface to be measured and the measuring wheel is moved around the perimeter of the object. As the wheel rotates, the linkage arm transfers the measurement to a scale on the planimeter that indicates the area of the object in square units. Planimeters are commonly used in fields such as surveying, engineering, and architecture to measure land areas, floor plans, and other geometric shapes. Types of planimeter: - There are three main types of planimeters: 1. Amsler polar Planimeter -  Also known as the linear planimeter, this type of planimeter measures the area enclosed by a curve. It consists of three main parts - the tracer arm, the measuring wheel, and the fixed reference point. The tracer arm follow...

What is Plane Table Surveying? Plane table surveying is a method of surveying that involves observing and recording the horizontal and vertical positions of objects from a fixed point (the plane table) using an alidade (a straight edge with sights or a telescope). The surveyor places the plane table at a point of interest and levels it using a spirit level. The alidade is then used to sight various features on the ground, and the surveyor notes the angles and distances to each feature on a sheet of paper attached to the table. These measurements are then used to create a map or plan of the surveyed area. Plane table surveying is often used in areas where traditional surveying equipment may not be practical or accurate enough. Instruments and accessories used in Plane Table Surveying: - Plane table surveying 1. Plane Table: A table that is levelled and used as a base for surveying. The plane Table is made of well-seasoned good quality teak or pine wood and is available in different siz...

Tacheometry Advantages and Disadvantages: - Advantages: 1. High Accuracy: Tacheometers are known for their high accuracy in measuring distances, angles, and elevations. 2. No Requirement for Line of Sight: Tacheometers do not require a line of sight between the instrument and the object being measured. This makes them suitable for use in areas where obstacles obstruct the view. 3. Quick and Efficient: Tacheometers are fast and efficient in measuring distances, angles, and elevations. They can measure multiple points in a short period, saving time and effort. 4. Multiple Applications: Tacheometers are versatile instruments that find use in various applications such as civil engineering, construction, mining, and topography. 5. Ability to Measure Slopes: Tacheometers can measure the slope of the ground, making them ideal for contouring and mapping. Disadvantages: 1. Expensive: Tacheometers can be quite expensive, making them unaffordable for small-scale projects. 2. Require Skilled ...
