“…The parameters "a" and "b" are site-specific since they depend on texture, structure, vegetative cover, infiltrometer type, moisture condition, rainfall intensity, permeability, soil surface conditions and properties (Al-Azawi, 1985;Moroke et al, 2009;Adindu et al, 2014;Smith, 1972;Adeoye, 2010 Dixon, 1976;Swartzendruber and Huberly, 1958;Childs and Bybordi, 1969;Carvalho et al, 1999;Berndtsson and Larson, 1987;Kelishadi et al, 2014;Dagadu and Nimbalkar, 2012). Giffobd, (1978) concluded, that it appeared that Kostiakov equation coefficients were related more to vegetation factors than to soil factors based on an analysis of data.…”
