WebThis means that there are four parameters to be defined in HEC-HMS to run the Green-Ampt method: 1. Initial Content – initial saturation as a volume ratio -- θ i 2. Saturated Content – total porosity as a volume ratio – n 3. Suction (mm) – wetting front soil suction head – ψ 4. Conductivity (mm/hr) – hydraulic conductivity – K 5. WebNov 5, 2024 · Surface irrigation is known as a highly water-consuming system and needs to be optimized to save water. Models can be used for this purpose but require soil parameters at the field scale.
