Accurate interpolation when compiling bathymetric maps is essential in any water depth study. In the case of Saldanha Bay, continuous dredging operations are constantly altering ocean floor, which has a detrimental effect on sedimentation and coastal hydrodynamics. If integrity coastline to be secured, accurate bathymetry predictions would invaluable determining erosion. Inverse distance weight...

When studying river hydrodynamics and water quality evolution laws on the basis of numerical simulation analysis, it is necessary to carry out topographic interpolation along bend direction measured section, as this can provide accurate reliable data for modeling. In paper, a two-step terrain method based sparse discrete sections proposed by comprehensively considering trends lack monitoring se...

The aim of this study is to assess the water quality surface body in area (Ikpoba River) Benin City using Geographic Information System (GIS). present research involved spatial analysis for four stations along Ikpoba River City. were delineated satellite images Google Earth. At same time, samples collected at these and parameters such as Temperature, Turbidity, pH, Total Dissolved solids (TDS),...

Resource estimation is one of the most important steps in mining process. Precise resource has a significant influence on optimization subsequent steps, i.e. mine planning and scheduling. The previous Angouran Mine was conducted based provided information local coordinate system which causes considerable errors estimations. Therefore, an attempt made this research to optimize block model UTM gl...

In this study, the southern expressway, which is first and lengthiest E class highway (126 km) in Sri Lanka, was analysed for roadside accident incidences. The primary objective of paper to identify best-fit interpolation techniques hotspots' most distinctive causes vehicular crashes. details were collected from Police Headquarters consisting 966 accidents that took place during period 2015 201...

Abstract Managing soils for improved agricultural production requires information on soil fertility status. Our objective was to map better management in Ethiopia and determine their spatial correlation at a separation distance of 29 m. We collected 82 samples (0–20 cm depth) 560 ha land determined pH, Olsen extractable phosphorus (Olsen‐P), organic carbon (OC). then interpolated between sample...
