Tidal estuary width convergence: Theory and form in North Australian estuaries

Gareth Davies, Colin D. Woodroffe, 2010.
Earth Surface Processes and Landforms v.35

In order to better understand the relations between tidal estuary shape and geomorphic processes, the width profiles of 79 tidal channels from within 30 estuaries in northern Australia have been extracted from LANDSAT 5 imagery using GIS. Statistics describing the shape and width convergence of individual channels and entire estuaries (which can contain several channels) are analysed along with proxies for the tidal range and fluvial inputs of the estuaries in question. ...

Seasonal tidal and freshwater chemistry of the south Alligator and Daly rivers

Chappell, John and Ward, Peter. 1985 in Coasts and Tidal Wetlands of the Australian Monsoon Region, eds K.N. Bardsley, J.D.S Davie and C.D. Woodroffe, Australian National University North Australia Research Unit Mangrove Monograph no.1, Darwin.
Describes major changes in inorganic chemical properties of two large tidal rivers, the Daly and the South Alligator, through the wet-dry season cycle. Wet season water quality is determined largely by flood runofffrom the catchment. Dry season chemistry is affected by turbulent diffusion of seawater upstream.

Undular tidal bore dynamics in the Daly Estuary, Northern Australia

E. Wolanski, D. Williams, S. Spagnol and H. Chanson
Estuarine, Coastal and Shelf Science, 60, 4, 629-636, 2004

"Measurements in the macro-tidal Daly Estuary show that the presence of an undular tidal bore contributed negligibly to the dissipation of tidal energy."

The sediment trapping efficiency of the macro-tidal Daly Estuary, tropical Australia

J. Woinarski, D. Williams and E. Hanert
Estuarine Coastal and Shelf Science, 69, 291-298

This report provides details into the sediment movement in the estuary region of the Daly River, this information is important to know with the new development pressures within the Daly River Catchment. New developments can result in increases in the sediment supply.

Environmental Impact of Undular Tidal Bores in Tropical Rivers

C. Donnelly and H. Chanson
Environmental Fluid Mechanics, 5, 5, 481-494, 10
Discusses the effects of a tidal bore on an estuarine ecosystem. A better understanding of periodic loading on river sediments, scour of river bed and flow mixing behind the bore will contribute to better management practices in tidal bore affected rivers, including the Styx and Daly rivers in tropical Australia.

The sediment trapping efficiency of the macro-tidal Daly Estuary, tropical Australia

E. Wolanski, D. Williams and E. Hanert
Estuarine, Coastal and Shelf Science, 69, 291-298, 2006
Field studies were carried out on the water and sediment dynamics in the tropical, macro-tidal, Daly Estuary. Sediment trapping in the estuary varies seasonally and inter-annually depending on wet season flows. A large sediment bar builds up during high flow wet seasons which can cause a freshwater ponding effect which takes about 3 successive dry years to disappear.

Estuarine fish: flow impacts on estuarine finfish fisheries of the Gulf of Carpentaria

I. Halliday
This project aims to increase our understanding of how freshwater flows in tropical rivers affect the abundance of some key estuarine fish species. Data collection will occur in the Gulf of Carpentaria and key catchments adjoining the gulf, including the Daly river.
