IrrigFlo

IrrigFlo is an open source java library for solving hydraulics flow calculations in hydraulics engineering. The aim of the library is to help other developers in creating their own desktop applications for hydraulics engineering that has the capability of commercial softwares.

Installation:

To install the library, download it from the releases page. It is advisable to download the latest release for updated features.

Usage

Solving trapezoidal shaped channel

import com.alexiusacademia.hydraulics.TrapezoidalOpenChannel;

public class TrapezoidalChannel {
  public static void main(String[] args) {
    // Create an instance of the class with a given unknown, Discharge
    TrapezoidalOpenChannel channel = new TrapezoidalOpenChannel(TrapezoidalOpenChannel.Unknown.DISCHARGE);

    // Setting the properties required
    // If some required properties are not set, getErrMessage will return a null message.
    toc.setBedSlope(bedSlope);
    toc.setBaseWidth(baseWidth);
    toc.setWaterDepth(waterDepth);
    toc.setSideSlope(sideSlope);
    toc.setManningRoughness(manning);

    if (toc.analyze()) {
      printLine("Analysis");
      printLine("Discharge = " + toc.getDischarge());
      printLine("Average velocity = " + toc.getAverageVelocity());
      printLine("Wetted area = " + toc.getWettedArea());
      printDash();
      printLine("Critical depth = " + toc.getCriticalDepth());
      printLine("Froude number = " + toc.getFroudeNumber());
      printLine("Flow Type = " + toc.getFlowType());
      printLine("Critical Slope = " + toc.getCriticalSlope());
    } else {
      printLine("An error has occurred: " + toc.getErrMessage());
    }
  }

  private static void printLine(String s) {
    System.out.println(s);
  }


  private static void printDash() {
