FAQs
What is a flood study?
A flood study is a technical project that identifies flood behaviour such as depth, velocity and extent across the floodplain for a wide range of flood events. It aims to provide an understanding of the full range of flood behaviour and consequences in the study area. It involves consideration of the local flood history, available flood data, and the development of hydrologic (rainfall and runoff estimations) and hydraulic (depth, velocity and extent of flood water) models. Where possible, models are calibrated and verified against historic flood events and then extrapolated to estimate the full range of potential flood events.
What is a Floodplain Risk Management Study and Plan?
A Floodplain Risk Management Study utilise the flood intelligence developed in a flood study to investigate possible mitigation options to reduce flood damage and to manage flood risk. It allows for testing and investigating practical, feasible and economic management measures, including structural and non-structural measures, to treat existing, future and residual risk. The Floodplain Risk Management Study will provide a basis for informing the development of a Floodplain Risk Management Plan.
The Floodplain Risk Management Plan will document the decisions on the management of flood risk within the floodplain into the future. The Plan will outline a range of measures to manage risk effectively and efficiently, using the investigations undertaken as part of the Floodplain Risk Management Study. This will include a prioritised implementation strategy, which will detail how measures will be implemented.
What Area is the Study covering?
The townships of Bawley Point, Kioloa and Termeil are covered by what is referred to as the Study Area.
The communities of Bawley Point and Kioloa are accessed via Bawley Point Rd and Murramarang Rd. There are a number of local catchments which are expected to overtop Bawley Point Rd and Murramarang Rd during intense rainfall events and this may result in the temporary isolation of communities. The study area included in this investigation is illustrated on the locality map.
How will this Study impact on me?
The objective of this study is to better inform flood risk management for property owners and publicly managed community assets. The overall goal is to increase community safety while mitigating damage to private and public assets.
This study will create flood intelligence for the NSW SES to plan and respond to flood events, develop an implementation plan for flood mitigation measures within the floodplain, and provide information to the community to improve their resilience during flood events.
