“…Subsurface tile drainage is a common practice used to facilitate rapid conveyance of drainage waters for optimal agricultural crop production. The upper midwest USA accounts for 58% of the corn and 70% of the soybean production in the USA (Kovacic et al, 2006). Thirty-seven percent of all the cropland in the midwest and cornbelt states is tile-drained (Fausey et al, 1995;Zucker & Brown, 1998), leading to significant amounts of channelization; and 25% of the waterways in Illinois have been channelized (Mattingly et al, 1993).…”

Understanding hydrology of channelized and natural headwater streams is paramount for maintaining ecosystem function and natural flow regimes. Two channelized and two natural headwater streams located in Upper Big Walnut Creek (UBWC) watershed in Ohio, USA, were instrumented to facilitate measurement, characterization and comparison of hydrology to the accepted paradigm for headwater hydrology. Data were collected at 10-min intervals from 1 January 2005 to 31 December 2006. Differences in flow magnitudes (average, low and high) were generally greater (P < 0.05) in the channelized streams. Frequency of zero discharge and out-of-bank discharge was significantly greater in the natural streams. Zero discharge occurred in summer and out-of-bank flows occurred in winter. Rate of change variables indicated that channelized streams respond more quickly to rainfall, have significantly greater peak flows, and have slower recession times. In contrast, natural streams tend to be more "flashy". The findings were generally consistent with the accepted paradigm for headwater hydrology and attributed to stream type, presence of subsurface drainage, potential connection to groundwater, and differences in riparian vegetation. The design and installation of management practices that influence hydrology should consider the potential impacts of altering stream hydrology. Management practices such as water-table management have the potential and show promise in altering the hydrology of channelized streams to resemble the hydrology of natural streams.

“…A runoff detention pond in Oklahoma, USA reduced sediment discharge downstream by 82%, total nitrogen by 56%, and total phosphorus by 60% [22]. A reduction in total nitrogen of 38%, and 56% in total phosphorus loading from a constructed wetland (a detention basin formed by berms adjacent to a stream) in Illinois, USA was reported by [23]. A shallow predam, a small reservoir aimed at improving water quality of a larger main reservoir downstream, in Luxembourg, was found to retain total phosphorus up to 60%, and a deep predam retained up to 82% [21,24].…”

An Economic Assessment of Local Farm Multi-Purpose Surface Water Retention Systems under Future Climate Uncertainty

Abstract:Regions dependent on agricultural production are concerned about the uncertainty associated with climate change. Extreme drought and flooding events are predicted to occur with greater frequency, requiring mitigation strategies to reduce their negative impacts. Multi-purpose local farm water retention systems can reduce water stress during drought periods by supporting irrigation. The retention systems' capture of excess spring runoff and extreme rainfall events also reduces flood potential downstream. Retention systems may also be used for biomass production and nutrient retention. A sub-watershed scale retention system was analysed using a dynamic simulation model to predict the economic advantages in the future. Irrigated crops using water from the downstream reservoir at Pelly's Lake, Manitoba, Canada, experienced a net decrease in gross margin in the future due to the associated irrigation and reservoir infrastructure costs. However, the multi-purpose benefits of the retention system at Pelly's Lake of avoided flood damages, nutrient retention, carbon sequestration, and biomass production provide an economic benefit of $25,507.00/hectare of retention system/year. Multi-purpose retention systems under future climate uncertainty provide economic and environmental gains when used to avoid flood damages, for nutrient retention and carbon sequestration, and biomass production. The revenue gained from these functions can support farmers willing to invest in irrigation while providing economic and environmental benefits to the region.

“…Moreover, information is needed on how IDS reactors can be best used in combination with technology such as good nutrient management plans, controlled drainage, treatment wetlands, and passive carbonaceous reactors. [16,22,25,26,41,43] There is good reason to be optimistic that future research will produce even more effective lower cost reactors. One promising area is the immobilization and simultaneous use of both denitrifying heterotrophic and autotrophic sludges.…”

Nonpoint source nitrogen is recognized as a significant water pollutant worldwide. One of the major contributors is agricultural drainage line water. A potential method of reducing this nitrogen discharge to water bodies is the use of immobilized denitrifying sludge (IDS). Our objectives were to (1) produce an effective IDS, (2) determine the IDS reaction kinetics in laboratory column bioreactors, and (3) test a field bioreactor for nitrogen removal from agricultural drainage line water. We developed a mixed liquor suspended solid (MLSS) denitrifying sludge using inoculant from an overland flow treatment system. It had a specific denitrification rate of 11.4 mg NO 3 -N g −1 MLSS h −1 . We used polyvinyl alcohol (PVA) to immobilize this sludge and form IDS pellets. When placed in a 3.8-L column bioreactor, the IDS had a maximum removal rate (K MAX ) of 3.64 mg NO 3 -N g −1 pellet d −1 . In a field test with drainage water containing 7.8 mg NO 3 -N L −1 , 50% nitrogen removal was obtained with a 1 hr hydraulic retention time. Expressed as a 1 m 3 cubically-shaped bioreactor, the nitrogen removal rate would be 94 g NO 3 -N m −2 d −1 , which is dramatically higher than treatment wetlands or passive carbonaceous bioreactors. IDS bioreactors offer potential for reducing nitrogen discharge from agricultural drainage lines. More research is needed to develop the bioreactors for agricultural use and to devise effective strategies for their implementation with other emerging technologies for improved water quality on both watershed and basin scales.
