Visiting Intern

Matthew Hemler is a Junior at Northeastern University studying Environmental Science and Geology. He is interning at Massey from May 5th to September 3rd to gain experience in river research and to learn more about fluvial geomorphology. While at Massey he will be quantifying habitat change and human modification along the Mangatainoka River using the natural character index.  He will also assist with grain size analysis on mine tailing deposits, and work with Andrew Neverman using satelite imagery to examine historic channel stability at selected streams.

‘Characterising natural river bed topography and flow conditions using high-resolution bed surveys’ Dr Jon Tunnicliffe, School of Environment, University of Auckland

Jon Tunnicliffe is a lecturer in Fluvial Geomorphology and a well-rounded sediment enthusiast in the School of Environment at the University of Auckland.

Thursday 30th  April, 11am, GLB 2.01, Palmerston North, All Welcome!

 With the introduction of high-resolution laser scanning and structure-from-motion techniques, we now have the capacity to resolve river bed topography down to the grain-scale over many kilometres. This profusion of high-resolution data invites the elaboration of increasingly detailed process models of river behaviour. However, at present, such 2d and 3d morphological models are computationally demanding, and tend to be poorly constrained in modelling river bed development at decadal to century timescales. The detailed topographic datasets, however, provide us with the opportunity to refine our parametrisation of fine-scale processes in conventional, coarser-resolution 1-dimensional (1D) models that integrate bedform and grain roughness elements over much greater (reach-scale) distances.

This talk provides an overview of some of the insights to be gained using numerical flow and sediment transport simulations on high-resolution riverbed topography for single thread, wandering and braided rivers. Using a set of NZ case studies, we examine the spectrum of river forms and the resulting distributions of depth and shear stress that characterise each. 

Monitoring and modelling the transport and fate of nutrients (nitrate) from farms to river via groundwater in the Manawatu catchment

Dave Horne and Ranvir Singh are developing and supervising postgraduate student research projects to help increase our understanding of the transport and transformation of nitrate-nitrogen via shallow groundwater in Manawatu River Catchment.

A sound understanding of the transport and fate of farm nutrients is a key component in our understanding and management of the likely impacts of these nutrients on fresh water quality and ecosystem health. While the cycling and transport of nutrients in the soil profile is reasonably well understood, there is limited information available about their transport and fate in the subsurface environment particularly in the Manawatu river catchment. Preliminary indicative assessments show that about 50% of estimated nitrate-nitrogen leached from the rootzone does not appear in river in some parts of the catchment. It is hypothesized that this 50% of estimated N-leached gets denitrified on its way from the rootzone to the river.

With this background, this project is set up as a postgraduate student research projects with the following objectives:

–      Analysis of nitrate concentrations and indications of denitrification in shallow groundwater

–      Laboratory and in-field measurements of denitrification in unsaturated and saturated zone sediments

–      Assessment of denitrification potential or occurrence among the most common types hydrogeologic settings           (climate, topography, soil and rock types)

–      Integrated modelling of water and nitrogen flow and transformations via shallow groundwater in the catchment

So far we are gathering field information and developing our instruments and procedures for field and laboratory studies, using Massey Dairy Farm No. 1, located strategically in a sensitive river catchment, as a testing site. The instruments and methods developed will be used to replicate denitrification measurements in different hydrogeologic settings in the catchment. The collected information will be used to assess transport (time lag) and potential transformation (denitrification) nitrate-nitrogen via shallow groundwater in the catchment.

The developed water and nitrogen flow modelling will be unique to the local situation and useful to the policy analysis required to formulate future land and water management guidelines for sustainable landuse in the Manawatu catchment.

This is a collaborative project between Massey IAE and Horizons Regional Council (HRC). We have now a team including Dr Ranvir Singh, A/Prof David Horne, David Feek (Technician), two PhD students (Mr Aldrin Rivas and Mr Elwan Ahmed) and a Masters student (Patrick Espanto) working on this. Horizons Regional Council (HRC) is partly funding this project, and providing access to their datasets, in-kind support and a contribution to field measurements and experimental components of the study. This funding and in-kind support is greatly appreciated.

Professor Russell Death

DeathDr Death is an Associate Professor at Massey University and will be visiting the University of Birmingham for three months between June and November 2014 hosted by  Dr Mark Ledger and Professor David Hannah from Geography, Earth and Environmental Sciences

Climate change is expected to increase the future occurrence of extreme hydrological events, such as severe droughts with potentially devastating effects on ecosystems, yet to date most ecological research effort has centered on the impacts of gradually shifting ‘average’ conditions, not extremes. Droughts are difficult to study in natural systems because they are, by definition, infrequent. Experiments have been advocated recently as useful tools to explore the ecologicalimpact of climate extremes, and research at the University of Birmingham is at the leading edge of this new trend. We have recently published a body of work in high impact journals which characterises drought effects at higher levels of biological organisation (i.e. food web patterns and processes; e.g. Ledger et al., 2011, 2012, 2013) and we are now beginning new NERC-funded research projects to explore underlying causative mechanisms (e.g. habitat loss, sedimentation, thermal stress etc.), including in our new ECOLAB facility on campus. UoB is also at the leading edge of hydrological research on drought and hydrohazards (as evidenced by the recent IAS workshop and UNESCO-International Hydrology Programme activities), and we are thus ideally situated to bring together hydrology and ecology at cutting edge of research to understand the environmental impacts of extreme events. Two immediate challenges arising from recent work are: 1) to better understand how shifts in food web structure and functioning caused by disturbances (floods, droughts) affect network stability in order to predict long-term responses of ecosystems to climate change, and 2) to upscale the work from patch-scale experiments and move towards prediction by developing modelling approaches which operate at spatial scales and timeframes relevant to managers and policy makers. 

Collaboration with Dr Death a world leading ecohydrologist, will allow significant advances in these key areas. Russell is a senior figure in the field of disturbance ecology with high-level expertise in the artificial intelligence modelling approaches that would allow us to make the leap to a more predictive science.

Full details of the plans for the visit will be available soon but will include work on the submission of manuscripts to internationally peer-reviewed journals, a workshop on the use of artificial intelligence modelling techniques for communicating complex science to managers, a public seminar ‘ Water management issues in the colonies: what can the UK learn from ‘down under’ and a workshop on using Netica and WEKA (both freeware) for statistical modelling in geography and ecology.
