Floodplains are the commercial, social and environmental arteries of the State. Transport and communication infrastructure are often located in floodplains and are a base for a significant proportion of the State’s agricultural business. Regular flooding enhances agricultural productivity by increasing soil moisture, recharging groundwater and depositing fertile silt across the floodplain. However, flooding can also interfere with production, communication, transport, emergency management and agricultural practices. Therefore development and management of floodplains needs to consider a broad range of issues including balancing the benefits of occupying the floodplain against the costs.
