**Formula:**

```
Hydraulic Gradient Calculation Formula: HG = (P2 - P1) / L
```

**Categories/Types/Range/Hydraulic Gradients:**

Category/Type | Range (Imperial) | Range (SI) | Interpretation |
---|---|---|---|

Gentle Slope | 0.001 – 0.01 | 0.0001 – 0.001 | Mild inclines, lazy rivers. |

Moderate Slope | 0.01 – 0.1 | 0.001 – 0.01 | Steeper terrain, moderate flow. |

Steep Slope | > 0.1 | > 0.01 | Waterfalls, fast-flowing rapids. |

**Examples of Hydraulic Gradient Calculations:**

Pressure Difference (P2 – P1) (psi) | Length (L) (ft) | Hydraulic Gradient (HG) (psi/ft) |
---|---|---|

10 | 500 | 0.02 |

5 | 250 | 0.02 |

15 | 300 | 0.05 |

**Different Calculation Methods:**

Method | Advantages | Disadvantages | Accuracy |
---|---|---|---|

Pressure Difference | Direct measurement, widely applicable. | Requires precise pressure and length readings. | High |

Flow Velocity and Slope | Accounts for flow rate and slope variations. | Complex instrumentation, data collection. | Moderate |

**Limitations of Hydraulic Gradient Calculation Accuracy:**
