      Lake Ellesmere / Te Waihora is located in the Canterbury region of the South Island of New Zealand. It is actually a broad, shallow lagoon located directly to the west of Banks Peninsula, separated from the Pacific Ocean by a long narrow sandy spit called Kaitorete Spit, or more correctly Kaitorete lies partially in extreme southeastern Selwyn District and partially in the. Central Canterbury Plains, New Zealand, showing a typical groundwater flow path provided by the groundwater flow model The agreed region for pilot study and model development is the km2 Central Canterbury Plains, in the South Island of New Zealand (Figure 1). These plains are bounded by the foothills of the Southern Alps, the Pacific Ocean. Water pollution in Canterbury in New Zealand has become a notable environmental issue due in a large part to the burgeoning dairy industry..

The tools may be used and disseminated to other users without charge provided their source is acknowledged and they are not sold for profit. Canterbury's water story Canterbury’s braided alpine rivers provide much of the water to our precious groundwater aquifers.

Originating in the Southern Alps, these river systems bring water across the Canterbury Plains, feeding the aquifers deep under the land. Groundwater resources beneath the Canterbury Plains are substantial, but are vulnerable to contamination.

The six year government-funded project involved several geologists and field assistants. Demand on water resources for irrigated agriculture on the Canterbury Plains is strong. Against a backdrop of tightening regulatory controls, demand for water has not abated, which is perhaps unsurprising given the significant economic benefits to be generated within the.

Canterbury’s groundwater resources are a significant natural resource and a strategic economic asset for the region.

For Ng—i Tahu, groundwater is regarded. Fundamental to the sustainable use of water is effective management. In the Canterbury region of New Zealand, nitrate contamination has become a resource management issue due to changes in land use and intensification, which have placed pressure on the region’s groundwater and surface water systems.

Canterbury, as the largest region in New Zealand, has the largest water resources and also the highest water use. It is estimated that around 70% of irrigated land in New Zealand falls within the Canterbury region. Groundwater is used extensively for irrigation and drinking water supply across the Canterbury Plains and in other inland basins.

• An overview of Canterbury’s groundwater resources and identification of the potential for natural vertical flow and pumping-induced leakage between sedimentary deposits located at different depth intervals to assist in the understanding of flow dynamics of the groundwater system and the measurement of hydrogeological parameters controlling groundwater flow.

Over most of the Canterbury Plains, groundwater levels, except in some deep aquifers, are currently at mean to above mean values, and record highs have been recorded in many regions this last winter.

A review. In: Scozzari A., Dotsika E. (eds) Threats to the Quality of Groundwater Resources. The Handbook of Environmental Chemistry, vol Abstract: The hydrological characteristics of the Waimakariri River and hydrogeological characteristics of the river bed on the Canterbury Plains are crucial to the management of groundwater in Christchurch City because most groundwater in Christchurch City aquifers originates from the Waimakariri River.

Deep groundwater flow paths however show groundwater to flow from the Central Canterbury Plains to the CGS. Potentially including losses from the upper Waimakariri River reaches.

If included, this places a net recharge amount to the CGS water budget, which if using losses from only the lower Waimakariri River, there is a net loss.

The other major source of groundwater recharge is leakage from rivers, and this river recharge is a significant feature of the groundwater resource of the alluvial aquifers of.

1. Introduction. Since the M w Darfield (Canterbury) earthquake on 4 Septembera.m. (local time), Christchurch and its environs have experienced an intense sequence of earthquakes and aftershocks. Most devastating was the M w Christchurch earthquake on 22 February at p.m. which resulted in significant destruction and damage, injuries and deaths.

Groundwater Canterbury has an abundant water supply through rivers, streams and very active groundwater regime including rich aquifers. It is estimated that o wells have been sunk within the Christchurch urban area since s (Brown and Weeber, ).

The dominant features of present day Christchurch are the Avon and Heathcote rivers. The resource Christchurch (population ) has one of the best water supplies in the world.

The supply comes from groundwater, is of extremely high quality, and requires no treatment. The groundwater system that provides this water is dominated in the west by gravels (possibly up to m thick) and sands deposited by the Waimakariri River. zones have been established to protect the quality of the groundwater resource accessed for public supply of drinking-water, especially from microbial contamination.

Nitrate concentrations in groundwater could pose a health risk to a small number of users of shallow domestic wells. The Waimakariri zone has a long history of farming land uses. The groundwater beneath the Canterbury Plains occurs within a thick sequence of Quaternary alluvial gravels.

It is recharged by rainfall that infiltrates through the soil and by water that seeps through the beds of the alpine rivers that cross the plains. Groundwater discharges near the coast, where it is the.

the Canterbury Plains, it loses water to the groundwater, and in the summer the river often goes dry for an extended stretch of river length along its main stem. Ground-water-fed springs contribute to lowland streams in the lower Orari catchment.

Christchurch drinking water is sourced from an area protected by Environment Canterbury's Natural Resources Regional Plan, called the Christchurch Groundwater Protection Zone.

The Rakaia-Selwyn Groundwater Zone is an unconfined aquifer that forms part of the Can-terbury Plains between the Rakaia River and the Selwyn River (Fig. Recharge is from rainfall and river seepage. There are groundwater-fed lowland streams that discharge into Lake Ellesmere (Te Waihora).

Addressing the entire hydrological resource, there was a focus on setting limits for both quality and quantity for the groundwater and surface water resources. To address this and to support a limit setting process, Environment Canterbury established a Hinds Plains Technical Team that includes water quantity and water quality scientists.

The new Central Plains Water (CPW) irrigation scheme will go some way towards addressing the over-allocated groundwater system, using water from the plentiful Rakaia River - including water stored. Irrigation using groundwater in Canterbury, New Zealand, is reaching sustainable limits and to assist with water allocation a better understanding of groundwater recharge from irrigated agriculture is.

The water moves slowly eastward down the plains to the sea. Aquifers are fed by rainfall and rivers. They also flow back into rivers and, on the lower plains, are the source of spring-fed rivers such as the Avon River in Christchurch.

Around one-third of the water used in New Zealand comes from groundwater. The Canterbury Natural Resources Regional Plan chapters on Ngai Tahu and natural resources, air quality, water quality, water quantity, beds of lakes and rivers, wetlands and soil conservation were operative from 11 Junereplacing the older Canterbury Regional Council Transitional Regional Plan (October ), which was a collection of.

The M W Darfield (Canterbury) earthquake, 4 Septembergenerated widespread hydrological effects in New Zealand ranging from instantaneous changes of piezometric levels, to more sustained postseismic changes in spring flow, river discharge and groundwater levels, and increased turbidity and declined yields of water abstracted from wells.

Abstract: Following a study into the variation in chemistry along two transects located on the Central Plains area of Canterbury, 18 wells were sampled for age-tracers (tritium, CFC, CFC, SF 6, 14 C.

The groundwater of the Canterbury Plains is a large, continuously-flowing body of water within layers of silts, sands and gravel down to depths of up to metres. This is not a static pond of water that we can “save for our grandchildren”.

What we do need to pass on to succeeding generations is wise management of this dynamic resource. An aquifer has been discovered under the Pacific ocean off New Zealand’s coast, with scientists saying some of the South Island could draw on it for their main freshwater supply.
