Swiftwater Speed Estimator vs Beam Deflection

PSDS Swiftwater Estimator is an educational tool that helps you estimate the surface speed of moving water using quick field inputs. Designed for training, planning & reference, this app provides a simple way to calculate a speed estimate for rivers, streams & swiftwater environments. Features: - Quick surface-speed estimates from user inputs - Built for swiftwater awareness and planning - Simple interface for fast field reference - Useful for training scenarios and educational use Important Disclaimer: This app provides estimates only and is intended for educational and informational purposes. It is not a replacement for professional judgment, training, or safety procedures. By using this app, you acknowledge that the publisher is not liable for decisions or actions made using the output of the app.

Beam Deflection is a civil engineering calculator for preliminary steel beam and 2D frame analysis. Define span length, IPE section, supports (pin, roller, fixed), and loads (point, distributed, moment). The app solves indeterminate beams using a 2-DOF finite element stiffness method and shows: • Support reactions • Shear, bending moment, and deflection diagrams • Peak values, elastic bending stress, and deflection limit checks (L/250, L/300) • Live beam schematic with section preview • 2D plane frame analysis — portal and multi-story grids with M/V/δ diagrams and deformed shape (subscription) • Learn tab — structural definitions and step-by-step calculation guides Intended use: educational and preliminary site checks. Not a substitute for licensed structural design or code-compliant calculations. Always verify results independently. Privacy: No personal data collected by the developer.
