What is the permissible slope range for implementing terracing?

• A. 0-5%
• B. 1-10%
• C. 2-14%
• D. 4-16%

Answer: (C)

The permissible slope range for implementing terracing is typically between 2% and 14%. This range is considered effective because terracing is designed to reduce soil erosion and manage water runoff on slopes. Slopes that fall within this range allow for effective water management practices, helping to retain moisture and improve soil health while also preventing erosion. Terracing involves creating stepped levels on land, which slows down water flow, allowing for better infiltration and reduced runoff. If the slope is too gentle (below 2%), the effectiveness of terracing diminishes as there may not be significant erosion issues to address. Conversely, slopes steeper than 14% may pose challenges for establishing stable terraces since the risk of erosion and runoff becomes much higher, making terracing less effective or impractical.
