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...

The lower Athabasca River watershed is one of the most important regions for Alberta and elsewhere due to fact that it counts for the third largest oil reserve in the world. In order to support the oil and gas extraction, Athabasca River provides most of the required water supply. Thus, it is critical to understand the characteristics of the river and its watershed in order to develop sustainab...

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),...

The comprehensive and accurate assessment of the indoor air quality (IAQ) in large spaces, such as offices or multipurpose facilities, is essential for IAQ management. It widely recognized that various factors affect well-being, health, productivity occupants. In environments, it important to assess places where difficult install sensors due space constraints. Spatial interpolation a technique ...
