The New Zealand Hydrological Society is excited to invite you to the 2018 Technical Workshop to be held in Palmerston North from March 6th – 9th 2018.

The Workshop is entitled “Discover the real dirt in hydrology”.  Over the four days, delegates will hear from a number of members of the hydrology industry on a range of subjects related to the challenges and successes in monitoring both water quality and quantity.

The specific topic that this workshop will address will be suspended sediment loads and the latest in best practice data collection, analysis and quality assurance of related data. Included in this will be comparisons of different data capture methods, laboratory analyses and surrogate technologies.

It is our great pleasure to welcome our overseas expert, John Gray, formerly of the USGS, who will present on the various aspects of sediment and its relationship to hydrology.

We look forward to seeing you in Palmerston North this coming March

Keynote Speaker: John R. Gray

John R Gray at NZHS workshop 2018John R. Gray is the Principal of GraySedimentology and the former National Sedimentologist with the U.S. Geological Survey’s Office of Surface Water.
​Gray brings some four decades of field and office experience in sediment-, streamflow-, and water-quality-data collection; program design, implementation, execution, and review; and program summary to bear on behalf of the client. The first 14 years of Gray’s 38 years of USGS experience were field- and project-work centric in three USGS offices in Illinois and Arizona. This experience enables insights on the riverine-transport processes and uncertainties, including sampler limitations and data uncertainties that may impinge on the significance of findings ranging from the data-collection to monitoring-program levels.
