open-channel-flow

Open MATLAB solver of the unsteady 1D Saint-Venant equations for channel design, flood routing, and dam breaks. Finite-volume kernel with HLL fluxes and hydrostatic reconstruction on cross-sections that vary along the reach, plus the legacy V5 Lax-Friedrichs model.

A virtual fluids lab in the browser: build a rig of pipes, pumps, valves and tanks and watch it solve live — water networks (EPANET in WebAssembly), gas and steam, open channels, water hammer, heat and control loops. 58 guided experiments. No server, no install.

Experimental comparative evaluation of closed-pipe (Venturi, Orifice, Pitot) and open-channel (Notches, Orifices) flow measurement devices under varying discharge conditions.

raslite —— 对标 HEC-RAS 的一维恒定流水面线推算程序 (Python 零依赖核心): 标准步进法/混合流水跃定位/河网汇流/HEC secant 临界水深/堤防处理; 与 HEC-RAS 6.2 官方及真实算例逐断面对比达厘米级 (0.2~1.3 cm)

A handbook for learning hydrology, hydraulics, flood-inundation modeling, validation, and scientific software practice.

Interactive one-dimensional river model for teaching what bridges, walls, buildings and blockages do to a river's water level, speed and bed. One HTML file, runs in the browser. A teaching model, not a flood risk assessment.

Open-source Python workbench for open-channel hydraulic design of irrigation canals - dimensioning, flow checks, and reproducible reporting.

Fluid mechanics for engineers in Python: a validated library, weekly teaching scripts for a full second-year course, notebooks and a showcase of advanced topics

Indonesian irrigation design calculations in Rust: open channel hydraulics, channel design and water requirement following the KP series

Physics-based vortex particle simulation for open-channel scour screening — Manning's equation alternative using Biot-Savart velocity induction and Kolmogorov turbulence cascade. 109 tests passing, MIT-licensed.
