There are three basic tile drainage layouts: parallel, herringbone, double main, and targeted (Figure 2). The design should allow for enough excess water to be removed within 24 hours to lower the water table to a level that will not cause crop injury, usually 6 inches the first day, down to a foot 48 hours later. Tile .
I. Determine if and where an adequate outlet can be installed! II. Estimate hydraulic conductivity (K) based on soil type. III. Select drainage coefficient (Dc) based on crop and soil type. IV. Use NRCS Web calculator. VI. Size laterals and mains to …
What is Subsurface Drainage? Subsurface drainage is buried perforated pipelines intercepting water below the ground surface and directing it to an outlet. Subsurface drainage often is referred to as “tile” drainage because until the 1970s, clay or concrete tiles were used to construct the subsurface pipeline.
Drainable water and tile system layouts. Locating tile lines in the field and introduce the drainage coefficient. Maintain water table at proper level for healthiest plant growth. Keep soil voids free of excess water, which permits air flow and allows important biological processes to …
Installing perforated pipe below the surface of a field to remove excess water is referred to as subsurface drainage, commonly called tile drainage. A typical tile drainage system has a number of small laterals, 3, 4 or 5 inches in diameter, that drain water to …
Photo-interpretation of color infrared aerial imagery can be used to map drainage tile patterns revealed after a heavy rainfall event. Previous research in Illinois and Indiana reported that the optimum conditions for aerial flights were 2 to 3 days after a …
Tile drainage system design Planning and designing an effective drainage system needs time and, of course, requires consideration of a number of factors, including: Water table level. Soil texture and class. Field elevation and slope. Current …
Subsurface tile or artificial drainage is the practice of placing slotted drain tubes beneath the soil surface well below tillage depth to help lower the water table of poorly drained fields and/or wet areas within fields.
Sep 10, 2015 · How do agricultural tile drain systems work ? Regional patterns for tile drainage. One way to look at tile drain system value. Maintain water table at proper level for healthiest plant growth. Keep soil voids free of excess water, which permits air flow and allows important biological processes to take place in soil.
Tile drainage - Wikipedia
Tile drainage is a form of agricultural drainage system that removes excess sub-surface water from fields to allow sufficient air space within the soil, proper cultivation, and access by heavy machinery to tend and harvest crops.
