Roadsand Bridges have evolved over time from their roots in footpaths and log bridges into modern transportation routes capable of carrying vast amounts of goods and services around the nation. Today's roads and bridges provide the physical connections that are the taproot of our society, and the safe operation of these roads and bridges is vital to our nation's prosperity. Approximately 86% of all bridges in the United States are built over streams.

According to Webster's Dictionary, hydraulic means operated, moved, or effected by the means of water. In a transportation context, this refers to drainage structures such as bridges or culverts. The purpose of hydraulic design is to ensure structures are of sufficient size that natural flooding is not worsened and to ensure that the structure can withstand the design flood and remain traversable. This is required in order to protect the property and residents upstream and downstream of a highway structure and any motorists who use the roadway. Hydraulic designers also must account for scour. Scour refers to the tendency of soil in a streambed to be washed away by flowing floodwaters.

Earth is a world of water. Roughly three-quarters of this planet is covered by water. The interaction between the sun and the water is the force behind life on this planet. Rain, falling one drop at a time, can produce tragic results. Since 1990, nearly all presidential declared disasters in Tennessee involved precipitation of some kind. Most have involved flood damages.

The Abyzz Hydraulic Design Tool makes it possible to calculate flow rates and flow rates in pipelines quickly and easily. With this data, it is possible to efficiently design piping and thus design energy-saving systems. It can be used for both metric and imperial units and includes a user guide in three languages (DE/EN/FR). In addition, pipe diameters can be easily determined with the integrated scales (metric and inch).

The purpose of hydraulic engineering is to design a structure with the proper capacity to divert or remove water from the roadway and pass collected water under the roadway. Designing a hydraulic structure requires knowing how much water is associated with the design storm (hydrology) and calculating the velocity, depth, and type of flow (hydraulics) that must be accounted for.

To help with hydraulic design, the Federal Highway Administration's hydraulic engineering professionals work closely with a software development firm as well as partners and stakeholders at Federal, State, and local agencies to develop and advance hydrologic and hydraulic software applications. These tools perform both routine and complex calculations to improve design efficiency and reliability. One of these applications is the FHWA Hydraulic Toolbox.

Specific calculators in the Hydraulic Toolbox address a wide set of design variables and features including rational method hydrology, roadside channel capacity, channel linings, curb and gutter sections, bridge scour analysis, and culvert assessment. The program enables users to perform and save hydraulic calculations in one project file, analyze multiple scenarios, create plots, and generate reports of the analyses. The procedures available in the toolbox are based on methods published in the FHWA hydraulic engineering library of technical reference documents, known as the Hydraulic Design Series (HDS) publications, and Hydraulic Engineering Circular (HEC) publications.

FHWA continues to expand the toolbox's functionality with new features. One of the latest enhancements is the bridge scour plotting tool. The scour calculator follows the procedures presented in the current (fifth) edition of HEC-18: Evaluating Scour at Bridges (FHWA-HIF-12-003), to assist users with analyses of abutment, pier, and contraction scour as well as long-term channel degradation. The Hydraulic Toolbox can generate a profile plot of the calculated scour components as well as the total scour elevations.

Although the Hydraulic Toolbox primarily functions as a stand-alone program, recent advances in the Surface-water Modeling System (SMS), another FHWA-sponsored hydraulics software program that performs two-dimensional flow analyses, have streamlined bridge scour calculations. SMS is now linked to the Hydraulic Toolbox scour calculator and assists users with determining the hydraulic parameters necessary for scour computations and transferring these parameters to the Hydraulic Toolbox scour calculator. Two-dimensional hydraulic modeling is included in round 5 of Every Day Counts as part of the Collaborative Hydraulics: Advancing to the Next Generation of Engineering (CHANGE) innovation. Visit www.fhwa.dot.gov/innovation/everydaycounts/edc_5/change2.cfm for more information.

Updated to version 4.4 in July 2018, the toolbox includes a Desktop Reference Guide with the software installation (accessible from the Help button on the top toolbar) to provide important information on the technical features, capabilities, and limitations of the calculators. In addition, the National Highway Institute offers an on-demand, web-based training course for the toolbox, course 135093. The free course takes 3 hours to complete.

The great thing about hydraulics is that you don't have to remember lots of complicated formulas to understand how things work. If you learn the basic principles shown in the following paragraphs, you can apply them to almost every other valve to understand how it works.

Valve dynamics are controlled by orifice restrictions within the design. In the valve shown the spool movement is delayed by how long it takes for the fluid volume held within an end chamber to flow through an orifice at the T port.

Smaller valves are often used to control the pilot flows of larger valves. Sometimes valves need to move very quickly to give a fast response while other times valve switching speeds may need to be slowed down to provide more stable operation.

Some fluid leakage will always occur through the clearances around the outside of a spool. It's this feature that means no metal touches and therefore hydraulic equipment takes such high power densities and duties for such long periods.

Leakage may reduce overall efficiencies but it does protect against trapped in pressures. Care must be taken to consider standby and switching conditions. For example, if port A is a sealed pipe then its pressure will always be a ratio of the P and T pressure based on the leakage across each land. Designs generally try to be either one or the other.

Poppets make physical contact with the seat and while you can never guarantee a 100% seal, poppets often do trap in pressure which creates the risk of extreme pressure caused by temperature changes. Every 15C rise will generate a 70bar increase in pressure.

Whenever the flow changes direction or passes through a different flow area, its local pressure will change. These pressure changes can have a significant effect on the spool or poppet pressure balance and therefore set position. Often significant work is carried out by valve manufacturers to limit the effect of flow forces within their valves.
