1. What is Land Slope?

Land slope is a measure of the steepness or incline of a terrain, expressed as a percentage. It represents the ratio of vertical change (rise) to horizontal distance (run).

2. How Does the Calculator Work?

The calculator uses the slope formula:

Where:

• \( Rise \) — Vertical height difference (feet)
• \( Run \) — Horizontal distance (feet)

Explanation: The formula calculates the percentage of slope by dividing the rise by the run and multiplying by 100.

3. Importance of Slope Calculation

Details: Slope calculation is essential in construction, landscaping, road design, and agriculture. It helps determine drainage patterns, erosion potential, and suitability for various land uses.

4. Using the Calculator

Tips: Enter the vertical rise and horizontal run in feet. Both values must be positive numbers. The calculator will output the slope percentage.

5. Frequently Asked Questions (FAQ)

Q1: What's considered a steep slope?
A: Generally, slopes above 15% are considered steep, while those above 25% may present significant challenges for construction.

Q2: How is slope different from angle?
A: Slope is a ratio expressed as percentage, while angle is measured in degrees. 100% slope equals 45 degrees.

Q3: What's the maximum possible slope percentage?
A: Theoretically unlimited, but practically, slopes approaching 100% (45°) are very steep, and beyond that becomes a cliff.

Q4: How do I measure rise and run in the field?
A: Use a level and measuring tape, or modern tools like laser levels or smartphone apps with inclinometers.

Q5: Why is slope important in drainage?
A: Proper slope ensures water flows away from structures. Typically 2% slope is recommended for proper drainage.
