The national model of recharge was used in the Waipa River catchment as one of three models to calculate recharge. Using the three models led to a better understanding of the uncertainty in rainfall recharge estimates for the catchment.
Data was requested by (and delivered to): - VuW (EWT estimates) - Taranaki Regional Council (rainfall recharge and EWT estimates) - Massey University (monthly water cycle estimates).
Surface soil moisture estimates can be made for 1 km x 1 km regions, using data of the Sentinel-1 satellite. Rainfall recharge estimates indicate that there could be significant recharge in mountainous areas, e.g., the Southern Alps. This was confirmed by findings of Cox et al., (2014). Validation of rainfall recharge, EWT and ET estimates have been completed for the Waipa River catchment.
The SAC and EartH2Observe project have held a workshop at the Groundwater Forum (Hamilton, 30 Nov 2015), in which both projects and their inter-relation were explained. The SAC part covered most of the satellite related work on evapotranspiration, rainfall recharge, and EWT.
Satellite-based water temperatures, rainfall recharge and EWT estimates were presented for feedback at a workshop on groundwater-surface water interaction (Wellington, 31 August and 1 September 2015). Feedback was very positive from all participants (64 people, from CRI, Regional Councils and Ministry for the Environment).
New TT DTS projects have been contracted or in the late planning phase with BoPRC, ES and HBRC. The BOP work is to establish methodology (timing, duration and complementary radon sampling) so the technique can be applied elsewhere in the Region. The ES and HBRC work is to input into construction and calibration of GW flow models.
Data worth analysis has a significant economic benefit by being able to quantify the worth of data (including the novel SAC based methods) in terms of how much they improve the reliability of model based decisions for the least cost. This analysis is being sought both by regional councils but also MfE are interested to optimise their national ground and surface water monitoring networks. Discussions to fund a prototype are being held.
M. Moreau attended a NEMS workshop on federated data exchange for environmental observations (EODP), 9 - 11 November 2015, Palmerston North. Attendees included: Horizons, Landcare, NIWA, MfE, LINZ, GNS Science. This highlights that we are now interacting with central government on standards issues.
Because of significant interest by the community in data access and visualization, A. Kmoch was invited to a regional council conference on environmental information management. In addition, significant interest in SOS and web-based utilities was generated by talks and posters at the NZ Hydrological Society Conference.
The SOS wireless monitoring network (installed at Upper Rangitaiki) is undergoing enhancement with a software upgrade pending. This will allow remote adjustment of the sampling frequency (i.e., the conference paper of Klug et al., 2015).
