Hydrological models are used to estimate the extent, depth, duration and velocity of flood waters under particular scenarios. It is common for models to include one or more previous flood events, and before-and-after development conditions.
Proposed and existing floodplain developments, such as levees and storages, have the potential to impact on flooding conditions at the development site, and both upstream and downstream of the site. Hydrological modelling is therefore a requirement of many application processes that involve floodplain structures.
Examples where hydrological modelling may be required include:
- construction of levees on floodplains (Part 8 Controlled Works)
- construction of storages on floodplains (Part 8 Controlled Works)
- assessment of existing works for compliance with the provisions of a Floodplain Management Plan
Western Land Planning works with a highly qualified third party provider on behalf of clients who require hydrological modelling. We develop the project brief, obtain quotes on price and timeframe, and manage the contract for the landholder. We act as a go-between to ensure that the finished product meets the landholder’s needs, and include the resulting report in other documents being prepared for the project.
Call us for a chat if you are proposing to undertake activities on a floodplain. Western Land Planning can help you determine whether hydrological modelling is required for your proposed (or existing) activities, and advise you on the most efficient way to proceed. We are familiar with the legislation that affects on-farm activities, and have excellent working relationships with most approval authorities.
