Resource management technical reports
Typically, deep, open drains are about 2 in deep and about 1 in wide at the base and dug with a backhoe or excavator. The movement of groundwater is controlled by two factors. One is the physical ability of the material to transmit fluid. Permeability is the measure used to describe the ability of a material to transmit fluid through pores and cracks. It depends largely upon porosity (the percentage of the total volume of thematerial that is pore space) and the degree of interconnectedness of the pore spaces. The other factor controlling groundwater flow is gradient. George (1985) found …

Soil conservation survey collection
This report was initiated at the request of the Neridup Soil Conservation Group as an aid to overcoming the degradation problems of the catchment known as the Neridup Creek Catchment.Work was commenced on collecting data about the catchment in May 1990 and has continued on a part-time basis as workload has permitted. This report outlines the physical details of the catchment, predicts runoff peak flows and contains recommendations as a framework for stable land use within the catchment.Attached to this report are: a set of maps of physical details, a set of plans related to individual degradation problems requiring solutions …
