“…However, the affected area on the NT was only about 2 ha, well below the recommended affected area size of 8 ha. Most studies to date on DWM have been on small (<5 ha) experimental fields (Skaggs et al, 2012), with the exception of Cooke and Verma (2012). Cooke and Verma (2012) used larger fields but did not determine the flow path of the held back water.…”

“…Many approaches to addressing the agricultural nutrient loading problem have been proposed, including riparian buffers, cover crops, altering timing and mode of fertilization, water table management, and off-field practices to increase denitrification (USEPA, 2007;Schipper et al, 2010;Skaggs et al, 2012). Previous research has found riparian buffers to be ineffective in locations where agricultural fields are drained via tiles directly into streams and ditches (Kovacic et al, 2000;Lemke et al, 2012).…”

Navigating the Socio-Bio-Geo-Chemistry and Engineering of Nitrogen Management in Two Illinois Tile-Drained Watersheds

Reducing nitrate loads from corn and soybean, tile-drained, agricultural production systems in the Upper Mississippi River basin is a major challenge that has not been met. We evaluated a range of possible management practices from biophysical and social science perspectives that could reduce nitrate losses from tile-drained fields in the Upper Salt Fork and Embarras River watersheds of east-central Illinois. Long-term water quality monitoring on these watersheds showed that nitrate losses averaged 30.6 and 23.0 kg nitrate N ha -1 yr -1 (Embarras and Upper Salt Fork watersheds, respectively), with maximum nitrate concentrations between 14 and 18 mg N L -1 . With a series of on-farm studies, we conducted tile monitoring to evaluate several possible nitrate reduction conservation practices. Fertilizer timing and cover crops reduced nitrate losses (30% reduction in a year with large nitrate losses), whereas drainage water management on one tile system demonstrated the problems with possible retrofit designs (water flowed laterally from the drainage water management tile to the free drainage system nearby). Tile woodchip bioreactors had good nitrate removal in 2012 (80% nitrate reduction), and wetlands had previously been shown to remove nitrate (45% reductions) in the Embarras watershed. Interviews and surveys indicated strong environmental concern and stewardship ethics among landowners and farmers, but the many financial and operational constraints that they operate under limited their willingness to adopt conservation practices that targeted nitrate reduction. Under the policy and production systems currently in place, large-scale reductions in nitrate losses from watersheds such as these in east-central Illinois will be difficult.

“…The remaining operating life of water drainage structures allows determining their safe operating life, with or without restrictions, or deciding to repair or demolish structures or their individual elements (Skaggs et al, 2012). The remaining operating life for the safe operation of water drainage structures is determined by a systems analysis with a development of a block diagram of the dynamic system that has a number of subsystems.…”

“…The term "wastewater" includes waters of various origin, content, and physical and chemical properties, which were used by humans for everyday and technological needs (Finger et al, 2013;Skaggs et al, 2012). During the process, the water was polluted, and its physical and chemical properties were changed.…”

One of the main problems facing big industrial cities is wastewater with hazardous substances, including petroleum products. A study of methods for optimizing spillways of city flume networks in Shymkent in South Kazakhstan region is presented in this paper. The influxes of flume networks and drainage (ground) water into existing rivers allow determining the aggregate intermediate volume (over a certain period) of surface runoff that enters the watercourses after rains. The estimations were based on data, collected at points of accumulation of surface water and rainwater, discharged into the Badam, Koshkar-Ata, and Karasu Rivers via optimal routes, in accordance with the methods of estimating the discharge of storm runoffs from the territory of settlements and enterprises. The paper characterized water discharges in the city by pollution categories and their nature, presented the main operating parameters of city treatment facilities, provided methods of estimating rainfall floods, a hydrological characteristic of estimated watercourses in the city, and determined the zoning of watercourses for rainwater and meltwater in the city territory.

“…Que, O. Seidou, R. L. Droste, G. Wilkes, M. Sunohara, E. Topp, and D. R. Lapen* G lobally, aquatic ecosystems are facing increasing pressures from nonpoint-source pollution coming from agricultural activities (Rabalais et al, 2002;Zhang et al, 2004;European Environment Agency, 2005;Michalak et al, 2013). However, there are many nonpoint source water pollution management practices capable of improving water quality in agriculturally dominated watersheds (Mostaghimi et al, 1997;Ice, 2004;Bracmort et al, 2006;Tuppad et al, 2010;Skaggs et al, 2012, Strauch et al, 2013. In many regions of North America and Europe, artificial subsurface (tile) drainage is widely used to improve field drainage for crop production.…”

Using AnnAGNPS to Predict the Effects of Tile Drainage Control on Nutrient and Sediment Loads for a River Basin

et al. 2015

Controlled tile drainage (CTD) can reduce pollutant loading. The Annualized Agricultural Nonpoint Source model (AnnAGNPS version 5.2) was used to examine changes in growing season discharge, sediment, nitrogen, and phosphorus loads due to CTD for a ~3900-km 2 agriculturally dominated river basin in Ontario, Canada. Two tile drain depth scenarios were examined in detail to mimic tile drainage control for flat cropland: 600 mm depth (CTD 600 ) and 200 mm (CTD 200 ) depth below surface. Summed for five growing seasons (CTD 600 ), direct runoff, total N, and dissolved N were reduced by 6.6, 3.5, and 13.7%, respectively. However, five seasons of summed total P, dissolved P, and total suspended solid loads increased as a result of CTD 600 by 0.96, 1.6, and 0.23%. The AnnAGNPS results were compared with mass fluxes observed from paired experimental watersheds (250, 470 ha) in the river basin. The "test" experimental watershed was dominated by CTD and the "reference" watershed by free drainage. Notwithstanding environmental/land use differences between the watersheds and basin, comparisons of seasonal observed and predicted discharge reductions were comparable in 100% of respective cases. Nutrient load comparisons were more consistent for dissolved, relative to particulate water quality endpoints. For one season under corn crop production, AnnAGNPS predicted a 55% decrease (CTD 600 ) in dissolved N from the basin. AnnAGNPS v. 5.2 treats P transport from a surface pool perspective, which is appropriate for many systems. However, for assessment of tile drainage management practices for relatively flat tile-dominated systems, AnnAGNPS may benefit from consideration of P and particulate transport in the subsurface.
