If you work with open-channel hydraulics , weirs , gradually varied flow , or seepage under structures , you have probably bounced between spreadsheets, textbook charts, and half-finished notebooks. FlowStudio is a small web app built to keep that work in one place: structured worksheets, clear outputs, and a project tree so you can find yesterday’s calculation. Try the app: https://flow.syncster.dev What FlowStudio is FlowStudio is a browser-based engineering workbook for hydraulic and civil topics. Each worksheet has a dedicated form: you enter geometry, discharge, slopes, coefficients, and so on; the app computes results and can show charts and schematics where it helps (for example, depth profiles, rating curves, section views, or Khosla uplift diagrams). Your inputs and outputs are saved as structured data so you can reopen a sheet and continue without redoing the setup. Organize work in projects and folders ...
