Floods: Protecting Crops & Infrastructure from Water Damage
A practical guide for flood preparedness and recovery in the Northern Adelaide Plains
Understanding Flood Risk in Our Region
Flooding can destroy crops, damage infrastructure, and delay planting. While the Northern Adelaide Plains is largely flat, heavy rain and poor drainage create significant risks—especially for greenhouses and tunnel houses. Taking action now can reduce long-term damage
Key Regional Risks
-
Flat terrain and clay soils = poor water runoff
-
Water trapped under plastic mulch or tunnel houses
-
Crop loss from standing water or root rot
-
Contaminated fertilisers and chemicals due to flooding
Preparing for Flood Events
Design paddocks with proper drainage or gentle contouring
Use swales and nature-based drainage like vegetated filter strips
Raise chemical and fertiliser storage off the ground
Select flood-tolerant crop varieties where appropriate
Maintain strong greenhouse foundations to reduce pooling
Response & Recovery
Pump/remove standing water ASAP to prevent disease
Inspect greenhouses, pumps, pipes, and drainage
Record and photograph all damage for insurance
Clean and disinfect all tools, equipment, and work areas
What Flood Resilience Looks Like
An effective and functioning swale to reduce flooding.
A well-constructured new polyhouse designed with flood resilience in mind: built on elevated ground for improved drainage and supported by functional swale.
Additional storm water drainage systems around structures.
