Erodibility of hill peat
(Teagasc, 2006-06-30)
The energy necessary to entrain soil in water depends on the soil strength. Once entrained, the settling velocity of the eroded soil in water is of fundamental importance to the processes of sediment transport and deposition. ...
Constructed wetlands for the treatment of highway runoff.
(Nova Publishers, 2008-06-01)
Highway surface runoff contains pollutants such as total suspended solids (TSS), hydrocarbons, de-icing salts, and heavy metals. Treatment methods for highway runoff include storage/treatment facilities, such as constructed ...
Evaluation of amendments to control phosphorus losses in runoff from dairy soiled water.
(Springer, 2011-12-01)
Amendments with the potential to reduce phosphorus (P) losses from agricultural grassland arising from the land application of dairy-soiled water (DSW) were investigated. Optimal application rates were studied, and associated ...
Cyclic loading tests on sandstone and limestone shale aggregates used in unbound forest roads.
(Construction and Building Materials, 2009-06-01)
This study examined the performance of two aggregates subjected to cyclic loading in a large-scale test rig. The two aggregates examined were: (i) a sandstone from Co. Cork, Ireland and (ii) a limestone shale from Co. ...
Nitrification in a vertically moving biofilm system.
(Journal of Environmental Management, 2006-06-01)
A laboratory continuous feed biofilm reactor, comprising a bulk fluid reactor, a biofilm plastic module, a feed tank, pneumatic devices and controls, was operated for a total period of 257 days, including seeding time, to ...
Repeated load testing of two schist and limestone aggregate materials used in unbound forest roads
(2009)
This study examined the behaviour of two completion aggregates that were placed on a silty sandy formation material and subjected to repeated loading in a large-scale testing rig. The completion aggregates were (i) a good ...
Impact of chemical amendment of dairy cattle slurry on phosphorus, suspended sediment and metal loss to runoff from a grassland soil.
(Science of the Total Environment, 2011-11-01)
Emerging remediation technologies such as chemical amendment of dairy cattle slurry have the potential to reduce phosphorus (P) solubility and consequently reduce P losses arising from land application of dairy cattle ...
Use of zeolite with alum and PAC amendments to mitigate runoff losses of P, N and suspended solids from agricultural wastes applied to land
(ASA, CSSA, and SSSA, 2015)
Diffuse pollutant losses containing phosphorus (P), nitrogen (N) and suspended solids (SS) can occur when agricultural wastes are applied to soil. This study aimed to mitigate P, N and SS losses in runoff from grassed ...
A novel hybrid filter for the treatment of septic tank effluent.
(ASCE Journal of Environmental Engineering, 2006-06-01)
Intermittent sand filtration is a common and effective method for treating septic tank effluent. However, if the loading rate is too high, clogging and ponding of the sand filter surface layer can occur due to the accumulation ...
Nitrate removal rate, efficiency and pollution swapping potential of different organic carbon media in laboratory denitrification bioreactors.
(Ecological Engineering, 2012-01-01)
Laboratory denitrifying bioreactors, which use an organic carbon (C) rich media to enhance microbial reduction of nitrate (NO3-) to nitrogen (N) gases, are used worldwide to protect surface and groundwater. To highlight ...
