NIWA’s LWL6001-S, is putting groundwater levels under the spotlight. The new laser sensor accurately measures groundwater surface levels to sub-millimetre precision. This sensor is ideal for anyone who needs the continuous, reliable data needed to effectively manage groundwater resources.
Time for a closer look at nitrates?
Nitrate (oxidised nitrogen) is the most widespread contaminant present in New Zealand groundwater - a concern for human health, the environment, and a potential barrier for primary sector exports. We investigate whether we need to monitor nitrate concentration continuously and look at progress in practical nitrate monitoring.
Meeting the flood challenge in post-quake Christchurch
The 2011 earthquakes ruptured much of Christchurch’s infrastructure—including its network of drains and open waterways. NIWA is working with the city council to remap storm-water flows across the city and provide the data needed to limit future flooding for residents.
Remote soil water measurement
Improved approaches to monitoring soil water movement can lead to the more efficient use of fertilizer, a reduction in nutrient waste and waterway contamination, and indicate the presence of coliform bacteria.
Water use strategy improving productivity and efficiency
Technologists, researchers, farmers, regulators and irrigation scheme operators are jointly evolving a water use strategy for Canterbury; one that benefits all stakeholders, can be scaled up, out, and will eventually improve water use efficiency for the benefit of all New Zealanders.
Harvesting and supplying flood water to irrigators, on demand
When Canterbury’s Rangitata River is running high, the new Rangitata South Irrigation (RSI) scheme can divert up to 20 cubic metres of ‘excess water’ into its seven massive storage ponds every second.
