This present study explores the use high-resolution multi-spectral remote sensing data for generating within-field soil variability map as an inputs required for site-specific management of agriculture. The study was conducted for an experimental plot in Central Potato Research Station of Jalandhar, India. Thirty-five soil samples were collected from the field at regular intervals. The samples ...

To enhance the vegetation signal in remotely sensed data and provide an approximate measure of live green vegetation, a number of spectral vegetation indices have been developed to estimate biophysical parameters of vegetation. The sensitivity of the normalized difference vegetation index (NDVI) to the soil background and atmospheric effects has generated an increasing interest in the developme...

Understanding land use land cover change (LULCC) is a prerequisite for urban planning and environment management. For LULCC studies in urban/suburban environments, the abundance and spatial distributions of bare soil are essential due to its biophysically different properties when compared to anthropologic materials. Soil, however, is very difficult to be identified using remote sensing technol...

Cone Penetration Test or CPT is one of soil investigation which used to determine the mechanical properties i.e., cone resistance and sleeve friction. Since several decades ago, often as a common thread physical such unit weight soil, behaviour type, etc. Thus, empirical approaches have been developed from various countries. However, these are not same condition in Indonesia. Therefore, it nece...

land degradation, or desertification, is specific to arid, semi-arid, and dry sub-humid regions. the rate of thisphenomenon is high in developing countries such as iran. this research investigated desertification and mapping ofdesertification in abuzaydabad, near kashan, iran, with an emphasis on land criteria using an imdpa model.different studies have assessed land degradation or desertificat...

Based on the knowledge of dimensional and mass features a forwarder, model was developed to assess its mobility during timber forwarding uphill in safe eco-efficient way. The is based position forwarder’s centre gravity, declared payload length loaded timber, as well gradeability for traction characteristics vehicle. connects two research approaches, (1) vehicle–terrain approach (distribution a...

A linear relationship between ERS-2 SAR backscattering coe cient (s0 ) and volumetric soil moisture was determined at both ends of a rainfall gradient in Israel. A Normalized radar Backscatter soil Moisture Index (NBMI) was derived and related strongly to soil moisture concentration. This index may allow the mapping of soil moisture conditions over large areas with C band SAR data.

A solution is developed for the evolution of buildup, steady, and postarrest dissipative pore-fluid pressure fields that develop around a finite-radius conical penetrometer advanced in a saturated linearly elastic porous medium. The analog with cone penetrometer testing is direct and is used to enable continuous distributions of permeability and diffusivity to be determined with depth. This ana...
