Estimation of the Soil Saturated Hydraulic Conductivity and Soil Sorptivity of Terraced Soil Using Four-Term Expansions of the Haverkamp Model

Uzunçayır water retention Dam is located in the Tunceli province. This semi-arid mountainous region eastern Turkey prone to erosion. To combat this phenomenon, terraces along edge of Munzur University campus were built on sloping ground with pine plantations. The objective twofold, one hand mitigate soil erosion and protect dam from sediments deposits, other promote infiltration rainwater vegetation soil. However, so-called ecofunctions over time are not proven. Monitoring capacities space will allow a better understanding their contribution hydrology watershed effect Beerkan technique offers simple inexpensive experimental protocols. In addition, treatment methods constantly improving. More recently, four-term expansion implicit Haverkamp cumulative equation has been proposed. complicated but robust formulation was used study estimate sorptivity S saturated hydraulic conductivity Ks terrace at Tunceli. average value studied site estimated be 0.0852 mm/s standard deviation 0.0112 mm/s. values more extensive mean 2.1227 mm/s0.5 0.5855 mm/s0.5. fit model perfect, showing that fast estimation possible using new model.
