Thanks for the information. Very insightful. I only have one other question. I guess I would use this only until the field capacity of the soil is reached, right. Some of the water will not ever drain down.
My soil has a approx. field capacity of 2 in/ft. So I can assume that if I have 30" of...
I have got a handle on how the water gets into the filter media. I need more information on how to calculate the flow coming out of the media to the underdrain.
If the media is dry, or at a normal moisture conent, then water is applied to the surface. The upper level then becomes saturated then...
I need to find the drain down rate of an infiltration basin with an underdrain.
If I have a filter media that is 30 inches deep, and I have a sudden rainfall that places a rapid 2" of water over my media. The media has a design infiltration rate of 2 in/hr. How will the water be routed through...
