Prof Jeff Walker - Curriculum Vitae
Work was commenced on my PhD in March 1996 at the Department of Civil, Surveying and Environmental Engineering, The University of Newcastle, Australia. The topic of my PhD was Estimating Soil Moisture Profile Dynamics From Near-Surface Soil Moisture Measurements and Standard Meteorological Data. This research was supervised by Associate Professor Garry Willgoose and Professor Jetse Kalma. My thesis was submitted for examination in June 1999 and accepted without change in February 2000.
Soil moisture varies in both time and space as a function of atmospheric forcing, soil properties and topography. Model estimates of this variation in soil moisture are often poor due to inherent model errors and an inaccurate knowledge of model inputs. Soil moisture measurements may be made at discrete points, but they are not always representative of the spatial variation in soil moisture. Remote sensing observations provide information on soil moisture in a thin surface layer at discrete times, but do not provide any information on soil moisture with depth. To overcome these shortcomings, an effective soil moisture monitoring scheme must utilise: (i) point measurements for model calibration and evaluation; and (ii) remote sensing observations for updating of the model to overcome the effects of model error and model input inadequacies.
This research investigated the effectiveness of the soil moisture monitoring scheme outlined above. In order to achieve this, it was required to develop an appropriate distributed soil moisture model for soil moisture forecasting, and to collect appropriate data for model calibration, evaluation and updating. Research efforts were focused on the following issues: (i) measurement of surface soil moisture from remote sensing; (ii) estimation of the satellite observation depth; (iii) techniques for assimilation of surface observations into the hydrologic model; (iv) importance of increasing the satellite observation depth on profile retrieval; (v) required frequency of surface observations to keep the model on-track; and (vi) the necessity for accurate model forcing and soil parameter values in such a soil moisture monitoring scheme.
1991 - 1995: Bachelor of Surveying and Bachelor of Engineering (Civil)
During this period individual degrees were completed for both Bachelor of Surveying and Bachelor of Engineering (Civil) at the Department of Civil, Surveying and Environmental Engineering, The University of Newcastle, Australia.
Honours Class 1 and University Medal were obtained for both degrees.
The title of my Honours project was Accuracy of DEMs (Digital Elevation Models). This research investigated the magnitude of elevation errors in published DEMs and the effect these errors may have on potential applications of this data. Of particular interest was the effect of these errors on hydrologic modelling. This investigation involved a Monte-Carlo analysis of geomorphic parameters used in hydrology by making comparisons with an accurate DEM. Hydromorphic parameters investigated include: (i) inferred catchment shape, size and stream network; (ii) width function; (iii) cumulative area diagram; and (iv) slope area diagram.

My primary research ambition is to lead programs in socially relevant research that will have a positive impact on the way we take care of the environment so as to result in an improved quality of life both now and in the generations to come. I believe that the key to this is through improved earth system state and flux monitoring, prediction and reporting, in a way that is relevant to policy and decision making processes, flood and drought prediction and assessment, land and water management, national weather and climate forecasting, etc. My vision is that this goal will be realised through a combination of i) environmental sensing, ii) earth system modelling, and iii) optimal convergence of model predictions with observations through data assimilation. This is a new area of research that has gained wide spread interest over the past years.
