Comparison of the Rate of Evaporation from Six Rolled Erosion Control Products
Rolled Erosion Control Products (RECPs) are temporary degradable or long-term non-degradable materials designed to reduce soil erosion and assist in the growth, establishment, and protection of vegetation. Although the diversity of products within the RECP category is beneficial from a cost competitive standpoint, it is often difficult for a designer to distinguish between the function of the materials due to the sheer number of products available. Six RECPs were tested in this experimental study to quantify the level of evaporation protection conferred to the underlying soil by the presence of an RECP. Moist soil was placed in polyethylene test containers to ensure one-dimensional vertical flow of the soil moisture during evaporation. Each RECP was tested in two conditions: full sun and buried in topsoil in shade. Additionally, a control test was performed on the soil, with no RECP covering. The mass of the soil container was monitored as a function of time and temperature throughout the day. Soil temperature remained fairly constant throughout the test, at approximately 32°C (89°F), while air temperature ranged from 30–37°C (86–99°F). In all cases, the presence of the TRM dramatically reduced the rate of evaporation, both when shaded and when exposed to full sun.
