Morundah is located within Federation Council, approximately 31km southwest of Narrandera and 44km north of Urana. It is located on the Newell Highway and has a population of 69 (2016 census). The village is located on the left bank of Colombo Creek, which is an effluent of Yanco Creek. Exchange of water occurs between the two creeks, regulated at Tarabah Weir (approximately 6km north of Morundah village) and occurring naturally along the floodplain. Morundah is protected by a low earthen levee approximately 3.2km long. The topography around Morundah is relatively flat, though runoff from the north and east drain towards the village. There are several bridge and culvert crossings of the Colombo/Yanco Creek system west of the village by Yamma Road, Newell Highway and the disused Narrandera-Tocumwal railway line.

The primary objective is to define the nature and extent of flood behaviour in and adjacent to Morundah village. The study will produce information on flood levels, velocities, flows, hydraulic categories and provisional hazard categories for 20%, 10%, 5%, 2%, 1%, 0.5%, 0.2% annual exceedance probability (AEP) events and the probable maximum flood (PMF) event.
