| Abstract: | This report describes the development of a surface-groundwater interaction model for the
Murrumbidgee Irrigation Area (MIA), situated in New South Wales, about 600 km west of
Sydney and 900 km east of Adelaide. The MIA includes the town of Griffith and Leeton, and the
study area covers the boundaries of 375250, 6150500 and 460000, 6230000 in UTM coordinate
system shown in Figure E-1. On July 13, 1912 the irrigation scheme was opened bringing water
to the area from storages (Burrinjuck dam – 1026 GL and Blowering dam – 1628 GL) through
rivers and supply channels, using gravity as the means to manage water flow. Rice growing
started in 1924 with its rapid development during 1970-80s. The total area for the MIA is
230,222 ha having dominant land use of rice with more than 32,000 ha in year 2000. Water use
by crops is presented in Table E-1. The rising watertable and salinisation have threatened the
viability of the MIA and this work is part of management strategies to ensure the sustainability of
the area. |
