Privacy Policy — Riprap Estimator Riprap Estimator Doc PP-001 Rev A Effective Jul 19, 2026 Legal · Data Handling Privacy Policy How Riprap Estimator handles the information it needs to run — written in plain terms, no boilerplate. 01 Overview Riprap Estimator is an engineering calculator for erosion-control riprap sizing. This policy explains what information the app touches, how it's used, and who you can contact about it. We keep this simple by design: the app is a calculator first, and it collects the minimum needed to make that calculator work. 02 What We Collect Data Purpose Project inputs length, width, thickness, material, velocity, wave height, costs Stored on your device to run calculations and populate your project sections.

Sizing Riprap the Right Way — Riprap Estimator Field Notes Riprap Estimator — Field Notes Dwg FN-014 Scale N.T.S. Rev A Design Reference · Erosion Control Sizing Riprap the Right Way A field guide to D50, flow velocity, and wave height — the three numbers that decide whether your armor stone holds a bank or ends up downstream. FHWA HEC-23 USACE EM 1110-2-1601 8 min read Riprap looks simple from the road — a slope of loose rock. But every stone on that slope is doing a specific job against a specific force, and undersizing even one class does not fail gracefully. It fails all at once, at the worst possible flow. 01 Why Riprap Fails Most riprap failures aren't material failures — they're sizing failures. A stone that look...
