Which slope gradient range corresponds to a low erosion hazard?

The range that corresponds to a low erosion hazard is the one that encompasses slopes from 0 to 7%. Slopes within this gradient are typically considered stable and less likely to experience significant erosion because water runoff moves slowly, allowing for better infiltration and reducing the force that can dislodge soil particles. When the slope is gentle, vegetation can effectively take root, providing additional protection against erosion.

In contrast, steeper slopes, such as those in higher ranges, experience much faster water runoff, which can increase erosion potential significantly as water gains speed and energy. Therefore, a slope of 0-7% is ideal for maintaining soil stability and minimizing erosion risks. This understanding is crucial for effective erosion and sediment control practices, particularly in areas susceptible to environmental degradation.
