Soil and Water Loss Process Solution - Kyushu Space asks you to answer - solve the ecological environment
The JZ-HE18 automatic soil erosion observation instrument is designed for field monitoring of soil erosion under various site conditions, as well as for fixed observations in standard runoff plots. It operates unattended throughout the field season, making it ideal for long-term and continuous data collection. The device consists of six main components: a runoff collection system, a runoff measurement unit, a runoff and sediment mixing mechanism, a sediment sampling segmentation system, a data logging system, and a rain protection cover. Its core functions focus on measuring runoff and collecting mixed sediment samples for accurate analysis.
This instrument can directly measure runoff from different areas, including those with varying land management practices, slope gradients, and lengths. It is especially suitable for soil and water loss monitoring in erosion control zones and development projects. The system records key parameters such as the start time of runoff, section runoff volume, and sedimentation levels. It can capture both single erosion events and cumulative totals, while also supporting year-round continuous observation.
The device offers flexibility, allowing users to choose different models based on catchment size and runoff capacity. It is lightweight, modular, and easy to install, requiring no external power supply. Features include automatic data recording, segmented sampling, internal data storage, and computer connectivity via USB. It generates synchronized rainfall, runoff, and sediment transport curves, providing comprehensive insights into erosion processes.
Compared to traditional standard runoff plots, the JZ-HE18 offers higher mobility, more realistic results under natural conditions, and the ability to monitor runoff intensity and sediment transport at specific intervals. It simplifies installation, reduces costs, and improves sediment measurement accuracy, with an error rate below 5% in sediment content tests ranging from 0.1% to 10%. The device is also compatible with large flow rates, easy to operate, and highly durable, ensuring reliable performance over extended periods.
The system includes a triangular runoff collector, a dumper, a runoff transfer tube, an electromagnetic sensor, and a data logger. A sediment mixer and sample segmentation collector ensure accurate sediment sampling. The data logger runs on a 3V button battery, lasting up to one year, and allows users to set data collection intervals and store data for up to six months. The device supports real-time data display and can be connected to a PC for data download and reporting using dedicated software.
It is widely used by research institutions, agricultural academies, and farms for soil conservation and erosion monitoring. With a simple mechanical design, it ensures low maintenance, high durability, and cost-effectiveness. The JZ-HE18 series comes in multiple models tailored for different applications, including small-scale monitoring, large catchment areas, and specialized erosion research.
Key technical specifications include a minimum runoff measurement range of 0.1–10 kg, a maximum runoff capacity of 320 kg/min, and a sediment content measurement range of 0–100 kg/m³. The device operates within a temperature range of 0°C to 50°C and has a service life exceeding 10 years. It is an essential tool for environmental scientists, agricultural planners, and engineers working on water and soil conservation projects.
