The Ōtūkaikino River : factors contributing to apparent macroinvertebrate loss.
(University of Canterbury, 2020)In recent years the Ōtūkaikino River catchment has had some of best water quality and stream health of all Christchurch rivers. However, the absence of stoneflies from macroinvertebrate surveys in 2017 indicates that all ... -
Resilient shorelines : earthquake effects on sea levels and their implications for conservation and climate change.
(University of Canterbury, 2020)Coastal margins are exposed to rising sea levels that present challenging circumstances for natural resource management. This study investigates a rare example of tectonic displacement caused by earthquakes that generated ... -
Assessing the use of geochemical modelling in supporting mine site remediation.
(University of Canterbury, 2019)The extraction of minerals through mining activities often results in the generation of acid mine drainage (AMD) due to the exposure of sulfidic minerals to oxygen and water at a rate faster than would have occurred ... -
Quantification of the probable environmental effects of the Hinds Managed Aquifer Recharge trial using mathematical modelling and advanced uncertainty techniques.
(University of Canterbury, 2019)Internationally, Managed Aquifer Recharge (MAR) has gained recognition as a mechanism to address environmental degradation. Investigations into its effectiveness in the New Zealand setting are ongoing and started with a ... -
Understanding Eiffelton Irrigation’s targeted stream augmentation.
(University of Canterbury, 2019)Eiffelton Community Group Irrigation Scheme (ECGIS) is a small owner-operated irrigation scheme located near the Ashburton Coast of Canterbury. ECGIS is bisected by a number of drainage channels which serve to lower the ... -
Increasing the uptake of building-scale water sensitive urban design stormwater management options in Christchurch, New Zealand
(University of Canterbury, 2019)Christchurch Ōtautahi, New Zealand, is a city of myriad waterways and springs. Māori, the indigenous people of New Zealand, have water quality at the core of their cultural values. The city’s rivers include the Avon/Ōtākaro, ... -
Constraining factors in water resources management and planning in the Plain of Reeds, Vietnam
(University of Canterbury, 2019)The research explores current water uses in the Plain of Reeds (Dong Thap Muoi) sub-region in Vietnam and identifies key constraints facing water resources management and planning. With increasing upstream demands on water ... -
Traditional and Western knowledge integration in water governance and its implications for rural livelihoods in Esigodini, Zimbabwe.
(University of Canterbury, 2019)Globally, the quality and quantity of water resources continue to decline, and there has been a realisation that water governance systems based solely on Western science, are not providing adequate solutions to the world’s ... -
A water quality study of Barkers Creek, South Canterbury.
(University of Canterbury, 2019)Diffuse nitrogen and phosphorus pollution from farming practices is a water resource management issue throughout New Zealand. Efficient management of diffuse pollutants requires a conceptual understanding of the relationship ... -
A habitat template of Stuckenia Pectinata in Te Waihora (Lake Ellesmere).
(University of Canterbury, 2018)Te Waihora (Lake Ellesmere) is a shallow coastal lagoon located on the east coast of the South Island of New Zealand. An extensive macrophyte bed (primarily Stuckenia pectinata and Ruppia spp.) once existed around the ... -
Negotiating gross national happiness as community economy : a case study of the Thimphu River.
(University of Canterbury, 2018)In recent years, the ecological health of the Thimphu River in Bhutan has been deteriorating. This leads to questions about the values that are ingrained in the Government’s development philosophy, known as gross national ... -
Examining the use of coral sand for the treatment of domestic effluent in Kiribati.
(University of Canterbury, 2018)Laboratory based, unsaturated drainage experiments were undertaken using worked Bikenibeu beach coral sand from South Tarawa in Kiribati, to examine its drainage and effective microbial removal properties. Bacterial and ... -
Urban impact assessment and emergency response to flooding in Buenos Aires, Argentina.
(University of Canterbury, 2018)The determination of urban resilience and community response to flooding are significant aspects of hazard management and disaster risk reduction. Anticipating hazard impacts is vital to the development of flood mitigation ... -
Phormidium accrual cycles in Canterbury rivers: the effects of nutrients and flow
(University of Canterbury, 2018)Over the last two decades there has been a marked increase in the intensity and frequency of proliferations of the benthic, mat-forming cyanobacterial genus Phormidium in rivers worldwide. This has raised concerns because ... -
A comparison of methods for estimating groundwater-surface water interactions in braided rivers
(University of Canterbury, 2018)Understanding how groundwater and surface water bodies interact is an important component of freshwater management. The direction and quantity of the flow between these two systems can vary in time and space, and these ... -
Virus transport from on-site wastewater treatment systems
(University of Canterbury, 2018)Viral pathogens present in wastewater, discharged to land from domestic wastewater systems, can contaminate groundwater and drinking-water supply wells. By understanding how viral pathogens move through soils, we can ... -
Glacial suspended particulate matter : character, composition and adsorption potential in freshwater environments
(University of Canterbury, 2017)Suspended particulate matter (SPM) plays an important role in regulating the transport and bioavailability of toxic trace elements and nutrients in natural waters. This research addresses the absence of data on glacier-fed ... -
The sorption of dissolved heavy metals from stormwater: the effect of biofilm, gravel, and two alternative substrates
(University of Canterbury, 2018)Stormwater acts as a major transport pathway for urban contaminants, with heavy metal contaminants of concern primarily being zinc, copper, and lead. In an effort to reduce the environmental impacts of stormwater, a range ... -
Identifying changes in groundwater quantity and quality resulting from border-dyke to spray irrigation conversion
(University of Canterbury, 2017)Over the past decade, the groundwater quantity and quality in the Hinds-Rangitata Plain (HRP) has continuously declined posing a serious risk to drinking water sources and waterways ecology. The aim of this project is to ... -
