Personal profile

Biography

Dr Callow’s research focuses is physical geography - the interaction of people and environment processes. His research is across the impacts of land management on hydrology, river geomorphology and ecohydrology in the Australian landscape. His applied research with government, industry and land managers/growers is focused on identifying management options and using emerging technologies to make better decisions in landscapes with changing land use, condition and climate.

Roles and responsibilities

• Field hydrology: establishment, calibration and maintenance of surface and groundwater monitoring networks.
• Field geomorphology: field reconnaissance, detailed investigations and monitoring, field and laboratory analysis, environmental flows assessment.
• Operation of rotary-wing (• Numerical hydrological modelling: MIKE, SHE/MIKE-11, HEC-RAS, SRM (Snow Runoff Model), XP Storm, SWIM, eWater Runoff Library suite, LEACHM.
• Surveying and use of total stations, GPS, DGPS and RTK-DGPS, RPAS Structure-from-Motion (SfM) photographic scientific topographic surveying and point cloud processing.
• Geographic Information Systems (GIS): acquisition, manipulation, editing, analysis and maintenance of spatial datasets using a range of software products: ESRI ArcGIS Suite, MapINFO, spatial modelling using Digital Elevation Models, remote sensing data analysis, programming in AML, Avenue, Python and VB.
• Accredited drillers offside (with Department of Agriculture and Food (WA)), some supervised driller training.
• Scanning Electron Microscopes (SEMs), Environmental SEM, Wavelength Dispersive Spectrometry analysis.
• Trained and Experiences in remote-area field work: Advanced Four-Wheel-Drive and recovery training, Remote Area First Aid Certificate, Senior First Aid Certificate.
• Qualified PADI SCUBA diver (Open Water & Boat Diver).
• UAV Controllers Certificate - • UOC Chief Controller UWA-Geography CASA-certified UOC operations.

Research

My research is focused on two themes, and a number of active research projects within these areas:

THEME 1 - Geomorphology, hydrology and ecohydrology of wetlands and catchments under pressure from climate, humans and land degradation. This theme focuses on processes and dynamics of river systems, riparian zones and wetlands, but also includes work on broader hillslopes, catchments and atmospheric processes and their interaction with landscape components. Projects include:
• Understanding palaeoclimates of the Snowy Mountains and environmental impacts of using silver for cloud seeding to enhance snow precipitation.
• Vegetation-based river management and biogeomorphology in salt-affected landscapes.
• Hydrological processes in low-gradient and data-sparse landscapes.
• Impact of climate change on hydrological, ecohydrological and geomorphological processes and landscapes, with a focus on biodiverse ecosystems of southwestern Australia.

THEME 2: Emerging and novel field techniques in Physical Geography. Research in this theme is focused on developing new approaches and novel use of existing and emerging methods and technology for field-based measurement and remote sensing to improve understanding of environmental processes.
• Use of Remotely Piloted Aircraft Systems (RPAS, also known as "drones" or Unmanned Aerial Vehicles (UAVs)) for studying environmental processes. Dr Callow is the Chief Controller and lead-researcher for the UWA-Geography CASA-certified UOC RPAS operations.
• GIS and spatial analysis of hydrological and landscape processes.
• Satellite and remote sensing methods to study data-poor landscapes.
• Distributed Temperature Sensing (DTS) - high resolution spatio-temporal measurement of temperature as an environmental process proxy.
