Polarimetric radar data (PRD) have potential to be used in numerical weather prediction (NWP) models improve convective-scale forecasts. However, thus far only a few studies been undertaken this research direction. To assimilate PRD NWP models, forward operator, also called simulator, is needed establish the relation between model physics parameters and polarimetric variables. Such operator nee...

Soil texture using a hydrometer or pipette method requires expertise, although these are accurate. A soil expert may help the farmer to detect by analyzing visual of soil, which is not always This paper presents smartphone image-based sand and clay classification in wet dry humid conditions Self Convolution Neural Network (SCNN) finetuned MobileNet.A dataset 576 images was prepared low-cost und...

In this study, liquefaction potential of the alluvial soils consisting clay, silt, and sand sized materials in Sahilkent (Bafra, Samsun) area was investigated using CPT data. Within scope 20 boreholes each having a depth 15 meters were drilled throughout Bafra district, one undisturbed soil sample obtained per meter from 5 these located area. Wet sieve, hydrometer, plastic limit, liquid natural...

Because of human activities, soil erosion has been one the most concerning issues in Malaysia past decades. This study aimed to estimate amount loss and sediment yield at Curtin University, by using Revised Universal Soil Loss Equation (RUSLE) Modified (MUSLE), respectively. The parameters RUSLE include rainfall erosivity factor (R), erodibility (K), slope length (L), steepness (S), cover-manag...

Highly plastic expansive clays swell or shrink due to change in moisture content and they often have very low bearing capacity. Construction of engineering structures particularly pavements lightweight buildings on problematic soils such as highly may create severe structural problems poor properties that kind soil. This study focused the influence fly ash strength which are their undesirable c...

Airborne measurements of vertical incidence radar reflectivity and radial velocity are analyzed for some 21 231 km of high-altitude flight tracks over tropical precipitation systems, in order to describe their characteristic vertical structure. The strength of the radar dataset lies in its superb vertical resolution, sufficient to detect unambiguously a bright band and the coincident Doppler ve...

The use of mechanical sieves has a great impact on measurement results because occurrence of anisometric particles causes undercounting the average size. Such errors can be avoided by using opto-electronic measuring devices that enable measurement of particles from 10 m up to a few dozen millimetres in size. The results of measurement of each particle size fraction are summed up proportionally ...
