Common interpolation methods include: Inverse Distance Weighted: points weighted by distance Spline Fitting: passes exactly through points with constraining equations Polynomial/trend analysis (nearest/natural neighbor) Kriging: weighted by fitted a plot of variance versus separation distance First Topic Second Topic Third Topic Fourth Topic Fifth Topic Second Topic Slide 10 T2_03 Second Topic 03 :) Second Topic: Final Slide Round up the maximum and/or minimum values and set the interval or the number of intervals Click on the Interpolate Surface button to create regular grid First Topic Second Topic Third Topic Fourth Topic Fifth Topic Second Topic Slide 11 T3_01 Third Topic 01 Third Topic Overview First Topic Second Topic Third Topic Fourth Topic Fifth Topic Third Topic Slide 12 T3_02 Third Topic 02 Third Topic Intermediate Demonstration of Dropdown List First Topic Second Topic Third Topic Fourth Topic Fifth Topic Third Topic Slide 13 T3_03 Third Topic 03 Third Topic: Final Slide First Topic Second Topic Third Topic Fourth Topic Fifth Topic Third Topic Slide 14 T4_01 Fourth Topic 01 Fourth Topic: Overview Drainage water management is most effective when implemented as part of an overall nutrient management plan. Such plans are developed to: budget and supply nutrients for plant production. properly utilize manure or organic by-products as a plant nutrient source. minimize agricultural nonpoint source pollution of surface and ground water resources. protect air quality by reducing nitrogen and/or particulate emissions to the atmosphere. maintain or improve the physical, chemical and biological condition of soil.

Practices are often combined to address weakness inherent in each component practice. When implemented in combination with bioreactors or saturated buffers, the standard control structure developed for DWM may be modified for dual use. Dual use structures are less expensive than the individual structures for each practice. Does not necessitate the use of a modified control structure Necessitates the use of a modified control structure First Topic Second Topic Third Topic Fourth Topic Fifth Topic Fourth Topic Slide 16 T4_03 Fourth Topic 03 Fourth Topic: Final Slide When DWM is implemented upstream of a saturated buffer, the outlet level may be set lower that it would be set if the practice were implemented on its own. The lower setting increases the potential soil water storage, thereby reducing runoff and the likelihood of flooding or erosion. Details of saturated buffers are presented in the Related Conservation Drainage Practices module.

The criteria used to define suitability include 1.Major soil components 2.Land slope 3.Hydric soil classification 4.Parcel contiguity Details of these criteria are presented in subsequent slides Suitable Acreage for DWM Illinois10,289,165 Indiana2,752,251 Iowa4,076,072 Missouri1,844,238 Michigan1,259,731 Minnesota6,308,982 Ohio2,146,231 North Dakota1,217,465 South Dakota228,842 Wisconsin309,427 First Topic Second Topic Third Topic Fourth Topic Fifth Topic Slide 19 T5_03 Fifth Topic 03 Fifth Topic: Toggling Example Soils occur in associations, and its unlikely that a field or mapping unit will only contain one soil. All of the soils in a field may not be suitable for drainage water management. A parcel meets the components criterion if the majority of the soils are suitable. First Topic Second Topic Third Topic Fourth Topic Fifth Topic Slide 20 T5_04 Fifth Topic 04 Fifth Topic: Final Slide To minimize water leakage from the edges of drainage water management systems, fields or sections of fields are considered more suitable if they are larger than 15 acres. The Edge Factor (EF) of a field may be defined as the ratio of the perimeter of the field to the perimeter of a square of equal area. The closer the EF is to unity, the more suitable the field is for DWM.

Both systems are instrumented to measure flow and water table levels. Additional Material 01 Additional Material Managed Drinage When the outlet level was raised in the DWM system, water leaked over into the free drainage system, and vice versa when the outlet level was lowered. Source Free Drainage Managed Drainage Water leaked from the free drainage system to the DWM free drainage system when the outlet level was lowered. Water leaked from the DWM system to the free drainage system when the outlet level was raised.
