Relative linkages of stream water quality and environmental health with the land use and hydrologic drivers in the coastal-urban watersheds of southeast Florida.

ABSTRACT: A systematic data analytics was employed to determine the relative linkages of stream water quality and environmental health with the land use and hydrologic drivers in the coastal-urban watersheds of southeast Florida. Power law-based partial least squares regression models were developed to reliably estimate the linkages by appropriately resolving multicollinearity (Nash-Sutcliffe efficiency = 0.72-0.95). The analytics indicated Everglades as the external and the largest source of total nitrogen (TN) in the coastal-urban streams for both wet (June-October) and dry (November-May) seasons. The "external driver" exhibited 1.5-2 times stronger control on stream TN than that of the watershed "land use," "hydrology," and the "upstream reach" contributions. In contrast, Everglades appeared to b
