Kyushu Space Mobile Soil and Water Loss Laboratory will be listed soon
The mobile soil erosion laboratory is a portable experimental system designed for on-site investigation and observation of soil erosion processes. It consists of a variable slope soil test tank, artificial rainfall simulation equipment, a runoff and erosion measurement system, power supply, lighting, water supply, and drainage facilities. The system also includes a computer data processing unit, a leveling support structure, and additional components such as a generator and instrument cabinet. This innovative device enables researchers to conduct controlled experiments in the field, offering greater flexibility compared to traditional fixed soil erosion tanks.
The development of this mobile laboratory represents a significant advancement in the study of slope erosion. Unlike conventional soil erosion tanks that are stationary and limited in adjustability, this system allows for slope angles to be adjusted between 0° and 30°, enabling more accurate and diverse testing conditions. It significantly speeds up data collection and reduces the overall experimental cycle. Moreover, during its design, the equipment was specifically modified to suit the characteristics of soil erosion in the Yangtze River basin, including the addition of a soil flow collection device, making the system more practical and efficient.
This mobile lab supports research into surface soil erosion, runoff patterns, sediment production, and the hydrodynamic behavior of slopes. It can also be used for monitoring soil and water conservation efforts in construction projects without requiring the installation of on-site monitoring infrastructure. This not only saves time and resources but also enhances the accuracy of erosion predictions. By conducting both disturbed and undisturbed soil rainfall tests, the equipment can directly measure accelerated erosion coefficients and provide a baseline for predicting soil and water loss during project planning.
Traditionally, soil erosion studies involved setting up field plots with varying slopes and vegetation cover, relying on natural rainfall for observations. While this method has provided valuable data, it is time-consuming and costly due to the unpredictable nature of weather conditions. To address these limitations, countries like the United States and Japan began developing laboratory-based simulated rainfall systems in the late 20th century, allowing for more controlled and repeatable experiments. In the 1980s, China started adopting similar technologies, such as the U.S.-made simulated rainfall devices. Later, the Chinese Academy of Sciences modified fire trucks to create large-scale artificial rainfall systems, which were quickly adopted in erosion research.
In 2004, the Chengdu Institute of Mountain Hazards and Environment developed a specialized soil erosion tank equipped with a dedicated water supply vehicle (modified from a fire engine) and a lower spray-type artificial rainfall system. However, these early systems were bulky and required multiple vehicles for transport, making field experiments labor-intensive and space-demanding. The new mobile soil erosion laboratory addresses these challenges by offering a compact, transportable, and highly efficient solution for real-time erosion monitoring and research.
