FAQS

The OpenFlows Hydraulic Toolset is a powerful hydraulic calculator software for civil engineers, technicians, and public works professionals. It is designed for quickly designing and analyzing individual hydraulic elements like pipes, culverts, and channels without needing to build a complex network model.

Yes, the toolset is perfect for sizing. It includes the capabilities of two powerful applications: CulvertMaster, which automatically calculates the right culvert size for specific flow and site constraints, and FlowMaster, which acts as a versatile sizing calculator to quickly determine the correct pipe diameter using various industry-standard formulas. 

The Hydraulic Toolset helps you perform a wide range of calculations for individual hydraulic elements without needing a full model. With the FlowMaster application, you can analyze and size pressure pipes, open channels, weirs, and orifices. The CulvertMaster application is dedicated to detailed culvert analysis and design. You can solve for nearly any property, such as pipe diameter, channel dimensions, flow capacity, or water depth—making it a versatile calculator for everyday design and analysis tasks.

Culvert analysis evaluates how water flows through a culvert to ensure a safe and efficient design. The Hydraulic Toolset provides CulvertMaster, a dedicated application for this task. It allows engineers to analyze complex scenarios using the official FHWA HDS-5 methodology. This includes evaluating crossings with multiple barrels, modeling potential roadway overtopping, and accounting for special tailwater conditions that affect performance, providing the detailed insight needed for culvert design.

The Hydraulic Toolset focuses on individual components. It is a set of powerful calculators for solving specific problems, like the design of a single pipe or culvert. In contrast, full network modeling software (OpenFlows Water or OpenFlows Sewer) is used to analyze the behavior of an entire system working together, such as a city's complete water distribution or sewer collection network.
