What weather conditions pose the highest risk for erosion on construction sites?

The highest risk for erosion on construction sites arises during heavy rainstorms and high winds due to the combined forces of intense precipitation and strong gusts. Heavy rain can overwhelm the soil's ability to absorb water, leading to surface runoff, which can cause significant erosion by washing away topsoil and sediment. The intensity of the rainfall is a critical factor; as it increases, so does the potential for erosion, particularly on disturbed soil surfaces typical of construction sites.

High winds exacerbate this situation by increasing the potential for soil particles to be dislodged and carried away. Wind can lift and transport fine particles, further destabilizing the area and increasing erosion rates. The combination of these two weather elements significantly heightens the risk of sediment loss and soil degradation, making construction sites particularly vulnerable during such conditions. Understanding this risk is essential for implementing effective erosion and sediment control measures.
