Hydraulic Structures Pro

Hydraulic Structures Pro works out the discharge, head or headwater of the structures that control open channel flow, and gives you the rating curve and a PDF report to go with it. It is made for civil, hydraulic and irrigation engineers, and for students of hydraulics. SEVEN STRUCTURES • Sharp-crested weir: rectangular with or without end contractions, V-notch and Cipolletti, with the Villemonte reduction for a submerged crest. • Broad-crested weir: critical flow over the crest on the total head, with a check against the modular limit. • Ogee spillway: pier and abutment contractions, and a coefficient that follows the head away from the design head. • Orifice: circular or rectangular, free or submerged. • Sluice gate: free and submerged underflow. Solve for the discharge, the gate opening or the upstream depth, with the thrust on the gate. • Culvert: headwater in inlet and outlet control after FHWA HDS-5, for concrete pipes, corrugated metal pipes and box culverts, with the performance curve. • Stilling basin: the hydraulic jump from either depth, its length and energy loss, and the USBR basin that suits it. FEATURES • Solve for the discharge or for the level that passes it. • Metric and English units. Switching converts what you typed. • A rating curve or performance curve with every result, with the solved state marked. • Notes that tell you when a result is outside the range its method was derived for. • PDF reports with the inputs, results, notes and chart. • Save calculations by name and open them again later. • Works offline. No account, no ads, no tracking. The results are for preliminary design and checking. The coefficients are typical values: confirm them for the structure at hand, and have the design reviewed by a qualified engineer.
