“…Because the highest pollutant concentrations are believed to be in low velocity, fine sediment zones, and not in high velocity, coarse sediment zones (Rhoads and Cahill, 1999), the conventional sampling protocols for pollution assessment of water bodies recommend sampling fine sediments on lentic geomorphic units of streams like pools or runs. In addition, hyporheic fluxes are generally ignored in sampling strategies of water or sediments (Boulton et al, 1998;Forsythe et al, 2013;Palumbo-Roe et al, 2012;Vervier et al, 1992).…”

“…Studies have indicated that kriging generally provides better results than spline and natural neighbour analysis (Voltz and Webster 1990;Laslett 1994;Pavão et al 2012;Duong and Gourbesville 2014). Different kriging approaches have been developed (Li and Heap 2014;Forsythe et al 2013; but ordinary kriging (OK) has been widely applied (Isaaks et al 1989;Robertson 2008;Soffianian et al 2015;Koko et al 2017) and was used here for the ponds and river. The general equation for estimating a value at a point z (Chang 2012) is:…”

“…Geographic information system (GIS) kriging is a spatial interpolation method to estimate a variable at an unmeasured location using observed values at nearby locations. Numerous studies have applied GIS kriging interpolation methods in the assessment of water and sediment quality to support management and remediation decision-making Murphy et al 2010;Lui et al 2011;Chen et al 2012b;Forsythe et al 2013). The primary objective of this study was to investigate the spatial variation of dissolved oxygen within the Cha-Am aeration lagoon system using the ordinary kriging (OK) interpolation method in ArcGIS10.1.…”
