Using stream flow and chemistry data to estimate catchment scale groundwater and nitrate fluxes
Groundwater is the dominant flow path carrying land surface recharge, including dissolved contaminants, to surface waters draining a catchment. The dominance of the groundwater pathway poses a challenge to management of ...
Discharge coefficients of flat-fan nozzles
(American Society of Agricultural and Biological Engineers, 2017)
The discharge coefficient (Cd) is a measure of how much of the pressure energy of a nozzle is converted into kinetic energy. With the discharge coefficient known, the exit velocity of the liquid sheet from the nozzle can ...
Export of nitrogen and phosphorus from artificially drained dairy pastures in the Hauraki Plains
This work forms part of the MBIE-funded Transfer Pathways Programme, which targets quantification of the pathway-specific transfers of nitrogen (N) and phosphorus (P) from the land to receiving waters, taking lag times and ...
A framework for understanding the linkages between land and water quality impacts
(Fertilizer and Lime Research Centre, 2017)
Different soils, landscapes and water pathways vary at a range of spatial and temporal scales in their propensity to yield, transport and attenuate contaminants. This affects a land's suitability t various types and ...
Critical pathways programme: Unravelling sub-catchment scale nitrogen delivery to waterways
(Fertilizer and Lime Research Centre, Massey University, 2019)
To be effective and efficient, decision making on land use, land management, mitigation measures, as well as policy, need to be based on a clear understanding of cause-effect relationships. Present practice is to link ...
