Predicting groundwater replenishment in arid catchments.

Temporary rivers, including intermittent and ephemeral rivers, make up roughly half the river systems globally, and closer to 70% of Australian surface waters. Yet our hydrologic understanding of these systems includes significant knowledge gaps, which are the subject of this project.  

PhD student Karina Gutierrez-Jurado is looking at the principal factors leading to streamflow in arid, intermittent streams. This combines theoretical modeling, a flow and climate change model of Pedler Creek, Willunga, South Australia, and fieldwork to understand flow permanence in the catchment.

Environmental Flow to the Lower Colorado River 

In March 2014, a historic e-flow was released at Morelos Dam, on the border between the U.S. and Mexico. After this pulse of water moved downstream, finally reconnecting the river to its delta for the first time in almost 30 years, it took almost five years to completely understand the ecological, hydrological, and social processes that occurred during the flow (read the final report here!). I co-supervised PhD student J. Eliana Rodriguez-Burgueno to use field and modeling techniques to estimate infiltration into the streambed throughout this reach.

Australia-Japanese comparative analysis of urban water-food energy security nexus

It is now widely accepted that meeting water, sanitation, and agricultural development goals requires a "nexus" approach to comprehensively address global issues holistically.This project compares wáter and energy needs for urban áreas in wáter-rich, energy-poor Japan, with wáter-poor, energy-rich Japan.

In October 2018, my colleagues and I travelled from Flinders University to Nagoya and Kyoto, Japan, to participate in workshops and discuss water-energy-food (WEF) nexus research. In March 2019, we will host our Japanese colleagues at Flinders to continue the discussion and analysis begun last year!

Hyporheic exchange in a wastewater driven stream

What happens to pharmaceutical products that enter our wastewater plants, and when these plants release treated wastewater into stream channels?  Can we use these compounds as tracers for hyporheic exchange? This is an exciting new field of research. This collaboration between the Leibniz Institute for Freshwater Ecology (IGB) and Flinders University conducted fieldwork and developed new modeling approaches to explore these questions.

Collecting field data for flows in ephemeral streams is a challenge; they are often remote, hard to get to when wet, with unpredictable flows and a lot of scouring when they flow..

Integrated water, soil and nutrient management for sustainable farming systems in South Central Coastal Vietnam and Australia

This project has examined the wáter and nutrient balances in the intermittent La Vi River catchment in relation to the changing agricultural practices underway in the region.

Predicting Water Resource Impacts from Unconventional Gas Development

Risk analyses describe possible impacts to water resources from unconventional gas production.  However, quantitative estimates that show probable impacts are crucial for decision-making and informing the concerned public. This project examined impacts of unconventional gas development on wáter resources world-wide in a first attempt to quantify the likelihood of contamination due to surface spills, subsurface migration of fluids, and aquifer depletion.
