Design Of Trapezoidal Notch Fall Pdf 25: A Practical Guide for Engineers and Students
A trapezoidal notch fall is one of the most common types of weirs used in engineering practice. It can be found in various applications, such as:
Irrigation and drainage systems
Hydroelectric power plants
Water supply and wastewater treatment plants
Environmental monitoring and research
A trapezoidal notch fall is a structure that consists of a horizontal crest with a trapezoidal opening on the top. The opening has a base width (b), a top width (B), and a height (h). The opening can be symmetrical or asymmetrical, depending on the ratio of the side slopes (z) to the vertical height (h).
A trapezoidal notch fall can be used to measure the flow rate of water in a channel or a pipe. The flow rate (Q) can be calculated by using the following equation:
Q = Cd * B * h * (1 + 2 * z * h / B)
where Cd is the discharge coefficient, which depends on the shape and size of the opening, the approach velocity, and the head loss.
A trapezoidal notch fall can also be used to control the water level or the flow rate in a channel or a pipe. By adjusting the height of the opening, the flow rate can be increased or decreased. The water level upstream of the weir can be maintained at a desired value by using a gate or a valve.
In this article, we will give you an overview of how to design and use a trapezoidal notch fall for different purposes. We will also provide you with a PDF file that contains detailed information and examples on this topic.
How to Design a Trapezoidal Notch Fall for Measuring Flow Rate?
If you want to use a trapezoidal notch fall to measure the flow rate of water in a channel or a pipe, you need to follow some steps to design it properly. Here are the steps you need to take:
Determine the range of flow rates that you want to measure. You need to know the minimum and maximum flow rates that you expect to encounter in your application.
Select a suitable location for the weir. You need to find a place where the channel or the pipe is straight, uniform, and stable. You also need to ensure that there is enough space upstream and downstream of the weir for the flow to develop and dissipate.
Choose the dimensions of the opening. You need to decide the base width (b), the top width (B), the height (h), and the side slopes (z) of the opening. You can use empirical formulas or tables to find the optimal values for these dimensions, depending on the range of flow rates and the accuracy that you require.
Calculate the discharge coefficient (Cd). You need to find the value of the discharge coefficient that corresponds to the shape and size of the opening, the approach velocity, and the head loss. You can use empirical formulas or graphs to estimate this value, or you can calibrate it experimentally.
Install and maintain the weir. You need to install the weir securely and levelly on the channel or the pipe. You also need to keep the weir clean and free of debris and sediment.
Measure and calculate the flow rate. You need to measure the water level upstream of the weir, which is equal to the height of the opening (h). You can use a staff gauge, a pressure transducer, or a float device to measure this value. Then, you can use the equation given above to calculate the flow rate (Q).
These are the steps you need to follow to design and use a trapezoidal notch fall for measuring flow rate. You can also refer to the PDF file that we have provided for more information and examples on this topic.
How to Design a Trapezoidal Notch Fall for Controlling Water Level or Flow Rate?
If you want to use a trapezoidal notch fall to control the water level or the flow rate in a channel or a pipe, you need to follow some steps to design it properly. Here are the steps you need to take:
Determine the desired water level or flow rate that you want to maintain. You need to know the target value that you want to achieve in your application.
Select a suitable location for the weir. You need to find a place where the channel or the pipe is straight, uniform, and stable. You also need to ensure that there is enough space upstream and downstream of the weir for the flow to develop and dissipate.

Install and maintain the weir. You need to install the weir securely and levelly on the channel or the pipe. You also need to keep the weir clean and free of debris and sediment.
Adjust and monitor the water level or flow rate. You need to adjust the height of the opening by using a gate or a valve, until you reach the desired water level or flow rate. You can use a staff gauge, a pressure transducer, or a float device to measure the water level upstream of the weir, which is equal to the height of the opening (h). Then, you can use the equation given above to calculate the flow rate (Q). You also need to monitor the water level or flow rate regularly and make any necessary adjustments.

What are the Benefits and Challenges of Using Trapezoidal Notch Fall in Hydraulic Engineering?
A trapezoidal notch fall is a simple and effective device that can be used for various purposes in hydraulic engineering. It has some benefits and challenges that need to be considered before using it. Here are some of them:
Benefits:
It is easy to design, construct, and install. It does not require complex calculations or sophisticated materials or equipment. It can be made of concrete, metal, wood, or plastic.
It is versatile and adaptable. It can be used for different applications, such as measuring or controlling the flow rate or the water level in channels or pipes. It can also be used for different types of fluids, such as water, oil, or gas.
It is reliable and accurate. It can provide consistent and precise results, as long as it is properly designed, calibrated, and maintained. It can also handle a wide range of flow rates and water levels.
Challenges:
It can cause head loss and energy dissipation. It can create a drop in the water level and a reduction in the flow velocity downstream of the weir. This can affect the efficiency and performance of the system.
It can be affected by environmental factors and disturbances. It can be influenced by the temperature, viscosity, density, and surface tension of the fluid. It can also be disturbed by the wind, waves, debris, sediment, or ice.
It can require regular maintenance and calibration. It can get dirty or damaged over time, which can affect its function and accuracy. It can also need periodic calibration to ensure that the discharge coefficient is correct.
