Abstract
The purpose of this study was to conduct a preliminary investigation of flow and water quality variability in a number of artesian springs around Christchurch City. Spring dynamics provide an important insight into the nature and state of the shallow aquifer beneath and immediately to the west of Christchurch city. The flow and quality of these springs also affects that of spring-fed streams and rivers flowing through urban Christchurch.
This research was initially designed to monitor springs only over the months of summer (November to February) in 2014/15. However, flow monitoring for some springs was extended through to August 2015, and even to July 2016 for the Ilam Garden springs, after it became apparent that low rainfall in 2015 could be having significant consequences for spring flow.
