“…A study by Horvath et al (2017) conducted in the contiguous United States, an indicator of PWA (Potential Wetland Area) was created using poorly drain soils, low relief landscape, and existing wetlands as the criteria (Horvath et al, 2017). Other wetland index studies also prioritized slope, proximity to watercourses, agricultural land, groundwater levels, soil permeability, availability of public lands, and socio-economic factors (Darwiche-Criado et al, 2017;Huang et al, 2010;Sivakumar & Ghosh, 2016). White & Fennessy (2005) included existing wetlands to increase size and connectivity of habitats as well as to further control point-source pollution.…”
