Calculator : Hydraulic Jump Conjugate Depth Solver
Category   : Fluid

Files Included:
  - hydraulic_jump.f90 (Fortran Source Code)
  - input.txt (Pre-configured Sample Input)

-------------------------------------------------------------------------
1. How to Compile
-------------------------------------------------------------------------
Make sure you have a Fortran compiler installed (like gfortran).
Run the following compilation command in your terminal:

  gfortran -ffree-line-length-none hydraulic_jump.f90 -o hydraulic_jump_calc

-------------------------------------------------------------------------
2. How to Execute
-------------------------------------------------------------------------
Run the compiled binary and redirect the input.txt file into stdin:

  hydraulic_jump_calc < input.txt

-------------------------------------------------------------------------
3. Input File Details
-------------------------------------------------------------------------
The input file 'input.txt' contains sequential parameters separated by
newlines. Here is the structure of the included 'input.txt':

  Line 1 (Channel Geometry (1=Rectangular, 2=Trapezoidal, 3=Triangular)): 1
  Line 2 (Channel Width ($b$) [m]): 4.0
  Line 3 (Flow Rate ($Q$) [m³/s]): 12.0
  Line 4 (Upstream Depth ($y_1$) [m]): 0.5
