Swakop River's 2009 flooding

The exitment around here for the last week or so has been our rivers. In Namibia all the rivers between the northern border and southern border are dry river beds. The rivers flow most years at least a little, but it's once in years, or even once in decades that the rivers actually reach the ocean.

At the coast we have two rivers in the vicinity of Swakopmund and Walvis Bay. The Kuiseb is just south of Walvis Bay, and it has nearly flooded into the lagoon. The Swakop river is here, just south of Swakopmund. Swakopmund's name comes from this river, the 'mund' being 'mouth.'

For us as birders there are aditional reasons for the interest. The river flows through the little wetland at the river mouth. Basically it's a bit like pressing a reset button. The whole system gets flushed out, and a somewhat new wetland is created. It all depends on how much water comes down and with how much power. This year it also depends on the human impact, digging trenches to encourage the river to flow out to the ocean.

We watched and watched. Everyone kept talking about the river coming down. It hasn't had a good flood into the Atlantic since 2000, so you can imagine that it's a big deal.

On Friday I went down with my boys. They had cut a long channel in the river bed. I am not too sure that it is a good thing. Anyway, the paper had said the river had already flowed, but when we were there, it certainly hadn't.

The man in the photograph is Dr. Hu Berry, a rather well known conservationist and guide in Namibia. Read more about him here. Him and his wife were also there to check it out when we got down there.

The river made it to the ocean later. It was fun walking around there the next day. The river had already dropped and clay was left where the river had flooded at it's highest. Full of bird's tracks.

The birds had changed remarkably little at a casual glance. I will, of course, be watching each day.

Everyone comes out to check it out, and the kids, including mine, have a good time in the river.

The ocean has washed very high over the last couple of days, and there were some images in the newspapers. I haven't been back to the river mouth, but will try to pop down tomorrow. It may be, if the river flooded so high, that salt water went into the small wetland at the mouth. I am not sure how significant this will be environmentally.

Kuiseb River Foods

It is with interest that I heard that the Kuiseb river has flooded.

The Kuiseb River flows south of Walvis Bay and cuts off the Namib Sand Sea (the huge dune field) from moving further north. This river is very important for the water supply in the towns of Walvis Bay and Swakopmund, as they drill into the river bed for water. So ironically, when the river floods we have water problems.

The kuisebs flooding is of interest to me for various reasons. First, if you live in dry places, it's just cool when a river flows.

Secondly, it is going to have an impact on the urgency with which the plans for a desalination plant get pushed. I am concerned that proper EIA evaluations get cut short. I am all for desalination, as it is probably the only sustainable way for us to get water at the central coastal area in Namibia.

Lastly, I am perhaps most interested because I hope to be taking people to the Kuiseb river on tour this year, and it's just going to mean more birds and more wildlife in the river.
