Ponded infiltration
WebOct 25, 2024 · The infiltration rate of water into ponded soil composed of discrete soil layers with various hydraulic conductivities can be estimated by infiltration tests. The steady infiltration into layered soil can be quantified as the flow through the homogeneous soil profile characterized by the effective hydraulic conductivities of the whole soil profile … WebC. infiltration is at the rate required by the department as verified by field measurements of the pond level performed by or under the direction of a professional civil engineer; and D. the construction of all required pond berm embankments is fully completed, and the embankments meet all applicable standards set forth in the Surface Water Design
