Many a kid has taken their bucket and spade to the beach and enthusiastically built a sand castle. The next day though usually ends in disappointment as the previous day’s efforts have been washed away by the tide. Sad, but a valuable life lesson perhaps.
River cut dam breached, from north bank looking south.
When I was a kid I also read about the 3 little pigs: a big bad wolf blows down the first two pigs’ houses, made of straw and sticks respectively, but is unable to destroy the third pig’s house, made of bricks. Seems like maybe bricks are a pretty good building material.

Continuing the life lessons, at least one Bible verse (Matthew 7:24–27) found its way into my learning. The World English Bible puts it like this:
Everyone therefore who hears these words of mine, and does them, I will liken him to a wise man, who built his house on a rock. The rain came down, the floods came, and the winds blew, and beat on that house; and it didn’t fall, for it was founded on the rock. Everyone who hears these words of mine, and doesn’t do them will be like a foolish man, who built his house on the sand. The rain came down, the floods came, and the winds blew, and beat on that house; and it fell—and great was its fall.
Of course there’s a deeper meaning, but the message about the impermanence of sand in the face of flood and wind is highly relevant.
This was the sand dam beside the rock groyne.
On 28 June 2018 the Council did a River Cut to divert our river more directly out to sea, rather than running beside the coast eroding properties and blocking vehicle access to the beach from Manga Pirau Street.
It took them all day and they created a good-looking straight channel and sand dam. Less than 10 days later and that sand dam has breached. The river’s busy carving sand off the edges of the channel. High tide is due and I suspect that before tomorrow dawns all the human endeavour will be reverted by the known forces of nature.
