The Murray Geological Basin is a large but relatively shallow Cenozoic sedimentary basin, extending over 300,000 km of south-eastern Australia (Figure 4.1). Some 23,000 km of the Murray Geological Basin occurs within 150 km of Broken Hill (Figure 3.1), with the north-west margin of the basin adjacent to the fractured rock uplands where Broken Hill is located (Figure 4.2). Contours for the base ...

We present a framework to characterize terrestrial functions—surficial and bottom topographic regions that are represented, respectively, as raster digital elevation models DEMs and digital bathymetric models DBMs —through analysis of flow fields that are simulated via geodesic morphology. Characterization of such functions is done via a new descriptor. Computation of this new descriptor involv...

The Mekong Basin Disease Surveillance (MBDS) network was formally established in 2001 through a Memorandum of Understanding signed by six Ministers of Health of the countries in the Greater Mekong sub-region: Cambodia, China (Yunnan and Guangxi), Lao PDR, Myanmar, Thailand and Vietnam. The main areas of focus of the network are to: i) improve cross-border infectious disease outbreak investigati...

Herbicide-resistant weeds are challenging for producers to control in crop fields. This study explores the potential of cover crops reduce weed pressure and improve soil health. Cover that had good canopy development, including grasses such as ryegrass wheat, best control. Soybean yields were similar all crops, though there was a trend towards lower brassica Graza radish forage collards. Soybea...

In addition to the striking beauty inherent in their complex nature, fractals have become a fundamental ingredient of nonlinear dynamics and chaos theory since they were defined in the 1970s. Moreover, fractals have been detected in nature and in most fields of science, with even a certain influence in the arts. Fractal structures appear naturally in dynamical systems, in particular associated ...

The effects of groundwater flow and biodegradation on the long-distance migration of petroleum-derived benzene in oil-bearing sedimentary basins are evaluated. Using an idealized basin representation, a coupled groundwater flow and heat transfer model computes the hydraulic head, stream function, and temperature in the basin. A coupled mass transport model simulates water washing of benzene fro...
