Introduction

1.1 Background-

Dryland salinity is when the salt is moved to the land surface with the ground water and is the most damaging form of salinity. The Southwest of western Australia is being over run by salinity and something needs to be done about it. The problem is getting so dramatic that it is predicted that within the next 50 yearsextinctions in the wheatbelt will cost us 450 species of plant, 280 species of invertebrates and 75% of waterbirds. In 1982 there were 264,000 hectares affected by salinity, by 1996 this number had increased to 1,804,000 hectares. Although there are many projects in place, I believe that the development of underground drainage could go a long way to eradicating this long term environmental problem.

1.2 Aim-

My aim is to put in place a project that over the next ten to twenty years can eliminate the threat that salinity is bestowing upon us. The project involves putting in place an underground drainage system that can elimina...
