The project mapped the landforms and land management units on cleared parts of the catchment ; defined the extent of, processes causing and options for solving the salinity problem in the Upper Denmark Catchment; developed a catchment management plan that would reverse the increasing soil and stream salinity trend within the catchment; encouraged and assisted the landholders to adopt the plan; and applied the results of the study to other areas.

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 …

Investigations were carried out to determine the interaction between the lakes and groundwater systems, the influence of bedrock structures on groundwater flow, and the regional flow characteristics in the basin. The hydrological investigations showed that water does flow from lakes to the groundwater system. However, the benefits from draining land have to be compared with the benefits of not adding water to the lakes. A basin water balance showed that most of the excess water resulting from reduced epotranspiration since clearing remains in the basin as increased groundwater storage. Only relatively small quantities of the extra water leave the basin …
