What is the primary purpose of using a tarp or cover on stockpiles?

The primary purpose of using a tarp or cover on stockpiles is to prevent erosion of loose soil and sediment from wind and rain. When stockpiles are left uncovered, they are susceptible to the erosive forces of precipitation and wind, which can lead to significant soil loss and sediment runoff. By covering these stockpiles, the cover acts as a barrier that shields the soil and sediment from direct exposure to the elements, thereby reducing erosion and the potential for sediment to enter nearby waterways. This practice is crucial in erosion control and sediment management strategies, as it helps maintain the integrity of materials stockpiled on construction sites or during landscaping activities.
