During the past week summer has brought its share of seasonal rain and flooding. This year the floods were particularly bad, cutting-off towns in the local district. Being flooded-in for a couple of days presented me with the opportunity to listen to the sounds of the flood at its various stages.
This shallow creek is usually only a few metres wide. I normally do a lot of hydrophonic recordings here as it is alive with the sounds of water bugs. On this day I placed the hydrophones in the floodwater and heard only the sound of the strong current:
As the rain eased the natural sounds were broken by the whir of military helicopters flying high overhead. They are often involved in evacuations, search and rescue, and food drops during periods of flooding.
Meanwhile my favourite sound during the flood was found in a shallow puddle on our driveway. Tiny air bubbles were rising from under the ground creating this sound heard through the hydrophones:
The floodwater has now subsided though more rain is predicted. This morning the valley was filled with the sounds of frogs enjoying a brief respite from the rain.
