…and Tide

 Village wharf as a spring tide comes in.

Time and tide wait for no one.

This is a maxim I thought I understood from my days sailing, but it has taken on new meaning as I live in the tidal delta area of Gulf Province PNG. Tides in our area average 2-3m, with spring tides sometimes going over 4m and neap tides having less than a metre variation at times.

This daily breathing in and out of the river system is part of life. It defines when and where you can travel, as some short cuts only work at high tide, and some routes are best followed with the flow of the tide, rather than travelling against it. The tide defines what people can catch and eat, as the greater the tidal variation in a day, the more the water is stirred up. I’m still learning which things are easier to catch in clear water, and which are more likely in muddy water.

 Same wharf when the spring tide went out.

Although the daily tide dictates life, it does not come into the village, but keeps within the river banks. It is king tides that cause flooding.

King tides occur due to a number of factors, growing bigger when some things align, such as when the partial solar eclipse occurred in January. Rain upstream from us also raises the water level, and although not a king tide, the flooding is similar.  This is when the water comes through the village, making life a little more interesting, as these photos show.

 

 Note the drain in this picture,
it is nearly a metre deep…

 …and vanishes in a king tide, so watch your step!

 Having avoided swimming in the drain with a mis-step,
I reached the bridge, only to find that it was floating,
which made crossing to the other side …’interesting’.
