Main functions The DIK-6000 rainfall simulator is used to simulate natural rainfall within a certain range, and can adjust the size and rainfall of raindrops, and is used in research in the fields of rainfall an
The characteristics of the simulated rainfall are the main indicators used to judge the performance of the rainfall simulators. The aim of this study is to investigate the potential of piezoelectric transducers for measuring and evaluating a dripper-type simulated rainfall drop-size distribution (DSD)...
A rainfall simulator was designed and tested for producing heavy rainfall intensities between 50 and 150 mm/h. The device is to be used on an artificial hillslope for the analysis of a shallow landslide triggered by heavy rainfall and consists of a looped pipe network that can accommodate a ma...
N2, and N3) and rainfall intensities 18, 28, and 56 mm h−1, used in the rainfall simulation experiments. The droplets were categorized into 22 sizes and 20 velocities. In order to summarize the droplet velocity and size in a single parameter describing the impact of the droplets on the...
Rainfall intensity in these events frequently exceeds 145 mm/h for short periods. For this reason, cumulative rainfall energy is often used to describe the potential of rainfall to cause erosion (Wischmeier and Smith, 1958; Loch, 1994) and to affect changes in the hydraulic conductivity of a ...
Rainfall interception is influenced by many factors, which are generally classified into two categories, i.e. climatic factors during rain event, and structural characteristics of vegetation7,8. Rainfall properties, especially the amount, duration and intensity of rainfall have often been used to ...
For each slope segment, five or nine measuring stretches paralleled flow direction were set to record stop-watch readings using dye tracer (KMnO4) method (Figure 1). The surface flow velocities (Vs) along all stretches were averaged to calculate Vs of the slope segment. At the middle (2.5 ...
However, it is important to note that the studies mentioned earlier were primarily conducted using model tests. In the field, erosion mitigation typically involves large areas. In addition, the artificial spraying method is commonly used for treating slope surfaces (Liu et al. 2021b; Meng et al...
The intensities under the rainfall simulator at BOKU were measured after each experiment with soil samples. The mean of totally three replicates per soil type and initial condition for defined position was used in the results. Under the rainfall simulator at BAW, the intensity for defined positions...
Ltd. was used to simulate rainfall from 4 m high above the soil flume. The rainfall simulator has 4 sets of down nozzles, and each set includes three nozzle sizes of large, medium and small. The overlap area of 4 sets of nozzles is the effective rainfall area of 2.5 m × ...
