1. What is a Slope Calculator for Drainage?

Definition: This calculator determines the slope percentage based on vertical drop and horizontal length measurements.

Purpose: It helps in designing proper drainage systems, landscaping, and construction projects where correct slope is critical.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( S \) — Slope percentage (%)
• \( h \) — Vertical drop (meters)
• \( L \) — Horizontal length (meters)

Explanation: The vertical drop is divided by the horizontal length to get the slope ratio, then multiplied by 100 to convert to a percentage.

3. Importance of Slope Calculation

Details: Proper slope calculation ensures effective drainage, prevents water pooling, and meets building code requirements for various applications.

4. Using the Calculator

Tips: Enter the vertical drop and horizontal length in meters. Both values must be greater than 0.

5. Frequently Asked Questions (FAQ)

Q1: What's a typical slope for drainage?
A: For most drainage applications, a slope of 1-2% (1-2 cm drop per meter) is recommended.

Q2: Can I use different units?
A: The calculator uses meters, but you can use any unit as long as both measurements use the same unit.

Q3: What's the minimum slope for effective drainage?
A: Generally, 0.5% is the minimum, but 1% is preferred to ensure proper water flow.

Q4: How do I measure vertical drop and horizontal length?
A: Use a level and measuring tape or laser level for accurate measurements.

Q5: What if my slope is too steep?
A: Steep slopes (over 10%) may cause erosion and require special drainage solutions.
