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.

Hydrology of the lower Daly River, Northern Territory

Chappell, John and Bardsley, Kristin. 1985. Australian National University, North Australia Research Unit, Darwin.
This survey describes statistical behaviour of the freshwater discharge of the Daly River just upstream of the tidal limit, and inundation of the floodplains below the tidal limit. Objectives of this report include description of the statistical behaviour of discharge throughout the wet season.

Landscape design for maintaining ecosystem services in tropical agricultural landscapes:

The response of fauna and flora to landscape mosaics and implications for land clearing policy.
Report to Land and Water Australia. Dept. of Natural Resources, Environment, The Arts and Sport, Darwin. Griffiths, A.D. et al., 2009
Project TRC07 - Managed through Tropical Savanna CRC

"To investigate the relationship between fragmentation, habitat loss and terrestrial biodiversity we conducted extensive surveys in the Douglas Daly region of the Top End of the Northern Territory in 2007 and 2008. This study shows that the impacts of land clearing on biodiversity are substantial at the scale of individual properties (represented as “landscapes” in this study), even if they retain some areas of native vegetation."
