Freshwater flow requirements of estuarine – dependent Fisheries – data review and research needs

Conceptual models of the likely impacts of freshwater flows have been developed for seven species or species complexes that are regularly caught in the commercial and recreational fisheries of the Gulf of Carpentaria and reviewed by researchers with experience in the Gulf of Carpentaria. These conceptual models have been used to develop a range of research that could potentially elucidate the linkages between the importance of freshwater flows and fisheries production.

Australia’s Tropical Rivers Data Collation Project

In response to the need to better understand Australia’s tropical river systems, this project aimed collating available datasets relating to Australia’s Tropical Rivers; and to then produce a set of relevant information suitable for upload to the Australian Natural Resources Atlas.

Indicator for Site-Based Erosion Assessment Using a Mixture of Field Data and Modelling

National Monitoring and Evaluation Framework

 This document reports on the Wind Erosion Assessment Model (WEAM) for field-based wind erosion risk assessment. The objective was to assess if WEAM could be used by regional Natural Resource Management (NRM) bodies to assess erosion levels of different land management practices on different (more)...

Separating almond evapotranspiration into soil water evaporation and crop transpiration

Separating Almond Evapotranspiration

The estimation of crop water use is a key input into much of the software which supports irrigation management. The most common method used to derive this estimate is to calculate it from weather data and coefficients specific to crop type and growing…

The potential to map the adaptive capacity of Australian land managers for NRM policy using ABS data

Resilience, vulnerability and adaptive capacity are terms increasingly used in rural policy, but rarely defined or converted into practical measures that support policy design and implementation. Adaptive capacity measures based on rural livelihoods analysis have been developed and trialled using ABARE data for broadacre industries. This paper provides a preliminary assessment of the potential to expand the application to all agricultural industries and to broaden the range of (more)...

Australia's Tropical Rivers

Data Audit

In response to the need to better understand Australia’s tropical river systems, the Tropical Rivers Data Audit was commissioned with funding provided by the Natural Heritage Trust’s Rivercare program. The project was undertaken between July and December 2003, by NGIS Australia in conjunction with Gutteridge Haskins Davey and Ecobyte Systems.

Economic and environmentally sustainable use of various water supply sources for irrigation

In spite of the availability of powerful, user-friendly, model-specific pre- and postprocessing software, groundwater modelling is difficult. One of the main reasons for this is the necessity to transfer large amounts of data into and out of models, and between models, databases and visualisation and display software. The Groundwater Data Utilities were written to complement existing models, and their graphical pre- and postprocessors, were developed in an attempt to overcome some of the (more)...
