Groundwater recharge interface and nitrate discharge: Central Canterbury, New Zealand
(Lincoln Ventures Ltd. Lincoln Environmental Research., 2005)
Regional surveys of groundwater quality in Central Canterbury, from 1977 to the present, show widespread occurrence of nitrate contamination primarily from agricultural land use. Two reported analyses of these surveys, ...
Extreme ranges of groundwater level
(Lincoln Ventures Ltd., 2008)
Large natural variations in groundwater levels can be an issue for selecting the depth of new water well installations or for evaluation of health risk from land treatment of waste, especially when these variations occur ...
Pathways from land to stream: lessons from Pukemanga
(Lincoln Ventures Ltd., 2007)
In the Pukemanga catchment, nitrate is leaching from soil under agricultural land use, and is being transported by subsurface water flow to surface waters. Groundwater is the suspected dominant transport pathway. This study ...
Adaptive management of groundwater in the Rakaia-Selwyn Groundwater Allocation Zone: technical and implementation issues
(Environment Canterbury., 2008-12)
This report recommends that a recharge-based groundwater management method be implemented. We describe a groundwater management method based on annual supply of recharge. The method varies the quantum of groundwater ...
Development of the AquiferSim model of cumulative effect on groundwater of nitrate discharge from heterogeneous land use over large regions
(Lincoln Ventures Ltd. Lincoln Environmental., 2007)
Regional-scale prediction of the effects of nitrate discharge from land use on the quality of the underlying groundwater requires two major model components: (1) a climate-driven model of agricultural land use that ...
Attitudes and barriers to water transfer
(Lincoln Ventures Ltd. Lincoln Environmental., 2001-12)
This project is part of the Ministry for Environment’s Water Allocation Programme. The programme is aimed at enabling sustainable development of New Zealand’s water resources by removing unnecessary constraints to water ...
The fate of carbon and nitrogen from an organic effluent irrigated onto soil : process studies, model development and testing
(Lincoln University, 2001)
The fate of the carbon and nitrogen in dairy farm effluent (DFE) applied onto soil was investigated through laboratory experiments and field lysimeter studies. They resulted in the development and testing of a complex ...
Towards an 'effective' relationship : landcare groups and local authorities working together to monitor indigenous vegetation on private land
(Lincoln University, 2000)
The idea of government agencies and communities working together to develop resource management strategies is by no means new. These community-based approaches to resource management decision-making are increasingly becoming ...
Towards integrated floodplain management in the lower Waimakariri floodplain
(Lincoln University, 2001)
As investment located on New Zealand floodplains increased and subsequently damaged by flooding, public pressure for new water control works mounted. This in turn led to calls for a more comprehensive and integrated approach ...
The impact of landfills on rural communities
(Lincoln University. Faculty of Commerce. Kellogg Rural Leaders Programme., 2005)
This report looks at the site selection process and construction of the modern day landfill and what the impact is on the local rural community.
