When you’re considering using a flume for the flow measurement needs of your water management operation, there are a wide variety of styles that you could choose. However, if you want one of the most distinct, useful flumes that exist, you should select a Cutthroat flume.
Using a Cutthroat flume means having a flow measurement tool that can be employed in a wide variety of situations and eliminates many of the other obstacles you can experience with other flume types. Read about the features that separate Cutthroat flumes from other flume types and discover how you can purchase this measurement tool for your operation.
Throat and Bottom
If you’re not familiar with the Cutthroat flume, you might expect it to have a similar design to every other flume on the market. However, this is not the case. For starters, this flume earned its name by completely eliminating its throat section. Instead, the inlet section of the flume immediately transitions to the diverging section.
In addition to removing the throat section, the Cutthroat flume differs from other flume types by having a completely flat bottom. This allows a Cutthroat to be fit directly into an existing channel, making it the perfect flume choice for operations where retrofitting is a necessity. A unique design makes the Cutthroat flume one of the best flow measurement tools on the market.
A major obstacle when it comes to choosing the right flume for your water management system is sizing. While most flumes are able to be custom constructed in a variety of sizes, sizing certain flumes up or down is a tremendous amount of work due to non-standard ratios. Fortunately, this isn’t an issue when you choose Cutthroat flumes.
With a cutthroat flume, the intel sidewall ratio is always three to one and the ratio for the diverging section sidewalls is five to one. Because these ratios are standard, entire lines of Cutthroat flumes can be manufactured by adjusting the sidewalls. Maximum customization is another reason you should consider using a Cutthroat flume.
Perhaps the main reason that water management systems across the country should consider using a Cutthroat flume is the ability to use this tool in a wide array of water measurement scenarios.
For example, because of its ability to sit flat in a channel, a Cutthroat flume is the perfect option to measure surface water flow. These flumes are also commonly used to measure irrigation, industrial, and sewage flows. However, when measuring sewage flows, certain adjustments will need to be made to avoid the risk of sedimentation.

For water management operations looking for consistently accurate measurements, one of the most common tools is a weir plate. In some situations, it’s easier for your weir plate to be located in a self-contained environment, which is the main purpose of a weir box.
A weir box contains both the weir plate and the weir pool in one enclosure, providing for an ultra-convenient flow measurement solution. If you’ve never used a weir box before, it can be a good idea to learn more about this tool and its numerous advantages. Read about using a weir box in your water management system and find out how you can purchase this tool from a trusted manufacturer.
Sizing and Flow Conditioning
The very first thing that you should consider when using a weir box is the amount of flow that you expect to experience in your system. What size weir pool is right for your system? Will your flow be constant or intermittent? Answering these questions will help you to decide what size weir box you need.
A similar issue to consider is the energy level of your flow. If you expect high velocity flow that may cause surface turbulence, you need to make sure that your weir box includes a baffle plate, which will help to minimize surface turbulence and improve the overall accuracy of your readings.
Another crucial factor in the usefulness of your weir box is how your weir plate will be mounted. Generally, a weir plate that is located in a weir box will be mounted to a bulkhead. This will make sure that it is secure and cannot be moved by energetic flow. Additionally, your weir plate should be mounted perpendicular to the flow for maximum efficiency.
You will also need to decide what notch shape you will use with your weir plate. While most weir plates will have a v-shaped notch, you could also choose a rectangular or trapezoidal notch. The notch that you choose will largely depend on the needs of your water management system.
The final issue that you will need to decide before installing your weir box is how your box will receive the flow in your system. The most common way for your weir box to receive flow will be with a piped connection. An inlet capable of being hooked to a pipe will be installed into the side of your weir box, allowing your weir box to receive the flow. Piped connections are generally used in an industrial situation.
When a piped connection isn’t an option, you can choose free spilling flow. With this setup, flow will spill from above into your weir box. Free spilling flow is a good choice when measuring flow in a natural channel.

One of the most common areas for water management operations to need accurate flow measurement is in an earthen channel. Usually, this will be accomplished through the use of a flume. However, when measuring flow in an earthen channel, there are two risks that you need to be aware of: flow bypass and downstream scour.
Experiencing either of these issues can drastically reduce the accuracy of your flow measurements and can impact the long-term success of your water management operation. Learn how to prevent flow bypass and correct downstream scour so that you’re able to accurately measure flow in an earthen channel with the right tools.
What Are Flow Bypass and Downstream Scour?
Before you can address the risks of flow bypass and downstream scour in your earthen channel, it’s a good idea to learn a few basic facts about these common flow measurement risks.
Simply put, flow bypass is when a portion of the flow is not captured by your flume, and instead escapes around the sides. Downstream scour is when the flow in your flume becomes too energetic, and wears away the channel downstream of your flume.
When you experience flow bypass, it can give you extremely inaccurate readings that indicate the volume of flow in your system is lower than it actually is. Downstream scour can reduce the integrity of your entire system, making it hard for your operators to take the measurements that your operation needs.
Fixing the Issue
There are a wide variety of ways to fix both flow bypass and downstream scour, meaning you may need to try a few solutions until you find the right option for your system.
Primarily, flow bypass is a result of a flume that is not installed level with the channel or is not properly fitted. When a flume is installed improperly or is too small for the channel in which it is being used, it can easily allow flow to escape. It’s always a good idea to install and size your flume with the help of a professional to avoid this issue.
It may also be possible to equip your flume with a skirt prior to installation. A skirt will allow your flume to capture the entire flow and may reduce the conditions that lead to downstream scour.
As mentioned, equipping your flume with a skirt can help combat downstream scour. However, if you find your flow is still too energetic, and scour is occurring, you might consider the use of an energy dampener. Using an energy dampener will slow your flow as it exits the flume and will lower your risks for scour.
Measure Flow in an Earthen Channel with the Right Tools
With the right plan in place, you can easily combat flow bypass and downstream scour. The best way to avoid these risks is to have the right tools for the job, and if you’re looking for tools to help you measure flow in an earthen channel, then you need to browse the impressive catalogue of products you’ll find withTracom, FRP.

There are countless excellent tools that you could use to measure the flow in your water management system, including weirs and a wide variety of flumes. Once you’ve chosen the right tool for your operation, the next most important decision is what material will be used to construct your flow measurement tools.
While it’s common for water operations to opt for metal measuring tools, these pose certain risks, such as corrosion and heavy weight. If you’re looking for the most versatile manufacturing material possible, you should consider fiberglass. Learn more about using fiberglass water management tools, and find out the many benefits of using this high-quality, durable material.
The drawback of using metal-like galvanized steel for your water management tools is that metal is extremely heavy. This can make it very difficult to install your tools and can make them hard to transport if you need to move your tools across your operation.
Fiberglass, on the other hand, is very lightweight. This means you can install your measurement tools quickly and effectively, and, if need be, you can transport your tools to multiple locations on your worksite without difficulty.
In a high-stress water management operation, it’s possible for your measurement tools to experience a tremendous amount of wear and tear over time. With metal products, this includes risks like rusting and corrosion, particularly if you’re measuring industrial flows or sewage.
If you want to make sure that your flow measurement tools last as long as possible, you need to make sure that they are made from fiberglass. Fiberglass possesses a thin gel coat that makes it resistant to corrosion as well as long-term ultraviolet damage. In addition, fiberglass is highly resistant to other forms of wear and tear, meaning you’ll be able to accurately measure your flows well into the future.
Additionally, this reduces the amount of maintenance that your system requires, freeing your operators to concentrate on other, more important tasks.
Install in Any System
One of the main obstacles that water management systems encounter is finding a flow measurement tool that is suitable for existing channels. Unfortunately, with materials like metal, it can be difficult to construct these tools in custom shapes, limiting their applications.
Customization is another advantage that fiberglass possesses over other materials. With the right mold, fiberglass can be formed into any shape that you need, meaning you can design your flow measurement tools to the precise specifications of your system. Choose fiberglass if you want your tools constructed in the right shape and the right size.

Flumes are the primary choice for water management systems looking to easily and effectively manage their flow. While there are different styles of flumes that your system could choose, flow measuring flumes will generally have the same basic parts. However, few people actually understand the different parts of a flume or their purpose, making it a good idea to examine these tools in closer detail.
When you learn about the parts of a flow measuring flume and their purpose, you will be able to use these tools more effectively, improving the success rate of your operation. Read about the parts of a flow measuring flume and find out how you can use these flexible tools in your water operation.
The very first section of your flow measuring flume is the most important. This is known as the converging section. The converging section of your flume is responsible for collecting the flow in your system and directing it towards the throat of your flume.
In addition to serving as the flow collection point, the converging section of the flume is where the primary point of measurement will be located. Generally, if your system operates in free-flow conditions, you will only need to measure at a single depth. However, your operators should always abide by the dimensions of your specific flume type.
Your Flume’s Throat
The middle section of your flow measuring flume is known as the throat. This is the narrowest section of your flume and serves one primary purpose: Accelerating flow. When flow enters the throat of your flume, it will be accelerated from sub-critical flow to super-critical flow. This will be accomplished through different methods depending on the type of flume you use.
If you have a Cutthroat or Montana flume, your flow will be accelerated using a contraction of the sidewalls. With an RBC flume, flow is accelerated with a change in elevation. Parshall and Palmer-Bowlus flumes use both methods. It is possible for certain flumes to have a zero length flow. In these flumes, the converging section will transition directly into the diverging section.
Read About the Diverging Section
Although it is not always necessary, many flumes contain a diverging section. The diverging section is where flow exists your flume. This section serves two important purpose. First, the diverging section reduces downstream scour in water management systems where this is a risk. Second, the diverging section expands flow back into the downstream channel.
In certain flumes, like a Cutthroat or Trapezoidal flumes, the diverging section may contain a second point of measurement. Other flumes, like HS/H/HL flumes, omit the diverging section completely.

If you’re looking for one of the most versatile, effective flow measurement tools in existence, there is no better option than a weir box. Weir boxes incorporate thin plate weirs and allow you to measure a wide variety of flows, increasing the success rate of your water management operation.
While trying to decide whether a weir box is the right choice for your water management system, you may have come across the term ‘baffle plate’, which might leave you wondering what a baffle plate is. Read about the uses of weir baffle plates and find out how you can purchase and install this important tool in your water management system.
What is a Weir Baffle Plate?
A weir baffle plate, also commonly caused a surge plate, is a tool that is installed in some weir boxes in order to more effectively control turbulent flow. When a weir box fails to include a weir baffle plate, it is usually in an effort to reduce installation costs and to save space. However, this can result in very serious consequences that influence the success of your operation.
For example, the only time a baffle plate is not needed is when your system possesses a long approach channel and low flow velocity. Since this is not common, it’s always a good idea to have your weir boxes installed with a weir baffle plate.
Uses of a Weir Baffle Plate
The primary purpose of a weir baffle plate is to mitigate the problems caused by surface turbulence. When the surface of your flow experiences a high level of turbulence, it can result in inconsistent flow measurements, and a reduction in the success rate of your water management operation.
Most weir boxes that include a baffle plate will use an underflow baffle plate. This tool forces flow to move under the plate, which removes turbulence from the surface of your flow. In addition, choosing an underflow baffle plate can eliminate the risk of surface foam, which is of particular importance in systems that use ultrasonic flow meters.
In addition to their ability to reduce surface turbulence and eliminate surface foam, using a weir baffle plate can provide your water management system with many other exciting benefits. For example, if your flow is piped into a weir pool, a baffle plate can help to normalize your velocity profile so that your operators are able to take more accurate readings.
Baffles also be useful in operations that measure dam seepage. In these systems, the baffle plate can be used to capture solid sediment so that it can be tested to ensure the health of the dam.
