Particle size distribution is an important soil parameter—therefore precise measurement of this characteristic essential. The application the widely used laser diffraction method for analysis continues to be a subject debate. precision method, proven on homogeneous samples, has been implicitly extended analyses, but not sufficiently well confirmed in literature thus far. aim study supplement information available terms reproducibility and whether characterized by normal distribution. To...
With regard to the differences between soil particle size distribution (PSD) obtained by sieve-sedimentation methods (SSMs), e.g., sieve-pipette method (SPM) and laser diffraction (LDM), usually, clay fraction content in LDM measurements is lower than SSM. Two groups of reasons can be identified for this. Firstly, resulting from features themselves. Secondly, sample preparation (after sampling) pretreatment (disaggregation). These not only cause difficulties PSDs comparability but also make...
Splash erosion is one of the form water erosion, where falling raindrops hit soil surface and result in detachment ejection splashed material, transport thereof over different distances. This process causes loss breakdown aggregates or responsible for displacement microorganisms, pathogens, pollutants within ejected particles. The a mixture solid (soil) liquid (water) phases aspects energy dissipation impacting drop during splash. Therefore, aim study was to present method estimation that...
Splash is the first stage of a negative phenomenon-soil erosion. The aim this work was to describe crown formation quantitatively (as part splash erosion) and compare course phenomenon on thin water film formed smooth glass surface saturated soil. height falling drop 1.5 m. observation crowns carried out by high-speed cameras. static dynamic parameters were analysed. It found that covering soil smaller time intervals their existence shorter. In addition, shapes different from those created...
The splash phenomenon and the scale of surface deformation post-fire soils in variants various hydrophobicity moisture content were studied. Splash erosion is result impact a single water drop was analysed using high-speed cameras, while parameterized structured light scanner. extremely water-repellent variant (dry_V) showed distinct differences, expressed primarily number ejected particles, which 2.5 times higher than four with lower levels hydrophobicity. It also observed that as onto an...
Abstract Soil aggregate water stability is very important from both scientific and practical points of view. This a critical factor in soil's susceptibility to erosion and, turn, land degradation. The most popular measure soil the resistance index (WRI), which commonly measured using wet‐sieving method. Using laser diffraction method order observe changes median particle size distribution determine was first proposed 2010. However, not suitable for weak aggregates. aim this study present...
The splash phenomenon is being increasingly explored with the use of modern measurement tools, including high-speed cameras. Recording images at a rate several thousand frames per second facilitates parameterization and description dynamics phases. This paper describes impact single drop liquid falling on surface same liquid. Three single-phase systems, i.e., water, petrol, diesel fuel, were examined. drops characterized by different kinetic energy values depending height fall, which ranged...
A splash experiment was carried out on a model soil–glass beads with diameter of 425–600 μ m using high‐speed cameras and sticky paper. Two different types particles were involved in the process: droplets water glass beads. We argue that result solid is best modeled as stochastic point process, is, random number randomly distributed points (beads) plane, provide basic physical statistical evidence that, medium distance range (i.e., for our experiment, ranges 29–64 mm), may be Poisson...
The formation of craters is an important issue in the investigations surface earth and other planets. aim study was to check whether different textures sand beds affect size dynamics ejection curtain after high-velocity impacts. experiments were conducted using aluminium impactor at two impact speeds (~700 ~1300 m∙s -1 ) a bed composed either broad range sizes (<2.0 mm) or any three fractions obtained from it (<0.5, 0.5–1, 1–2 mm). diameters, depths, wall slope, rim heights resulting...
Soil splash is the first step in process of water erosion, where impacting raindrops cause detachment and transport soil material. One factors that strongly influences magnitude incline surface (slope). The aim this study was to investigate effect slope on course phenomenon caused by single-drop impact (one drop per sample), with respect mass proportions ejected material, taking into account its division solid liquid phases i.e. water. investigation carried out using three types different...
Abstract Pistia stratiotes is an aquatic plant with a complex structure that allows it to stay afloat. It grows quickly, and in large numbers becomes undesirable as invasive species. Describing the dynamics of water drop splash on P. leaves can contribute increasing knowledge its behavior finding alternative methods for eradicating or using benefit environment. The non-wettable surface presents structure—simple uniseriate trichomes also ridges veins. We analyzed impact leaf placed recorded...
