What impact does a steeper slope have on erosion?

A steeper slope significantly increases the potential for erosion, and this is particularly true when considering the 'splash effect.' The splash effect refers to the way raindrops can displace soil particles upon impact, which is exacerbated on inclined surfaces. On steep slopes, gravity plays a more pronounced role, causing dislodged soil particles to flow downhill more rapidly.

In such an environment, not only does rainfall lead to greater soil displacement because of the increased kinetic energy from a fall over a greater height, but the water runoff can also accumulate velocity, further contributing to erosion. Therefore, steeper slopes create conditions that enhance both the splash effect and the likelihood of soil wash-off, making it essential to implement effective erosion and sediment control measures on such terrains.

Understanding the dynamics of slope and erosion is crucial for the management and protection of soil resources in construction and land development activities.
