Silverton is located approximately 25 kilometres north-west of Broken Hill and is accessible by sealed road. The central urban area is a typical grid pattern running in a north-south and east-west direction. The eastern extent of the urban area can be defined by Mindioomballa (Black Hill) Creek while on the north-eastern side of the village is Umberumberka Creek. Penrose Park, a recreation and camping area, which is used by large numbers of visitors and tourists, is located on the northern floodplain of Umberumberka Creek.

The objective of this study is to define the mainstream flood behaviours of Mindioomballa (Black Hill) and Umberumberka Creeks and their effects on the village area of Silverton in Phase 1. An assessment of local overland flooding is outside the scope of this study. Outcomes from Phase 1 (i.e. the Flood Study Report) will produce information on flood levels, velocities and flows for a full range of flood events under the existing catchment conditions. The Flood Study Report will enable SVC to progress in the next stage of the floodplain risk management process (Phase 2) by identifying the possible management options and a draft Floodplain Risk Management Plan for consideration by SVC.
