Garlic for engineers

Information has arrived from the Department of Arts, Heritage and the Gaeltacht. I have accordingly updated my page about the Ulster Canal and the Infrastructure and Capital Investment 2012-16: Medium Term Exchequer Framework.

Triangular quaternions

The indefatigable Mary Mulvihill has produced a podcast guide to a Royal Canal walk, from Dunsink to Broombridge. The podcast is free to download as an MP3 file.

Its production was supported by Maths Week Ireland and the Irish Research Council for Science, Engineering & Technology (IRCSET); it follows the annual walk to commemorate the achievement of Sir William Rowan Hamilton, who in 1843 invented a new type of algebra, quaternions, and wrote the equation on the bridge.

Mid Shannon Corridor Tourism subsidy

 

I have been trying for some time to find out whether anyone has taken advantage of the Mid-Shannon Corridor Tourism Infrastructure Investment Scheme. I sent this email to the Department of Transport, Tourism and Sport in July 2011; I received no reply, so I have sent it again today.

===begins=====

Your website’s list of contacts does not include an email address for the section of your department that deals with tourism [it still doesn’t, on 1 Novemebr 2011], so I would be grateful if you would pass this query to the appropriate person.

I have some questions about the Mid-Shannon Corridor Tourism Infrastructure Investment Scheme. I would be grateful if you could tell me how many applications for approval in principle have been received.

Could I have a list of the applicants and their proposals please?

How many applications have been approved?

Could I have a list of them please?

On how many projects has expenditure been incurred?

Could I have a list of them please?

The far end of the Shannon

Apologies to folk who have left Comments or otherwise communicated in recent weeks: I’ve been away, most recently at the far end of the Shannon and at Greenwich. I am now beginning to tackle my correspondence.

De Wadden

De Wadden formerly traded to the (Munster) Blackwater and is now displayed in a dry dock at Liverpool. I knew she was there, but I hadn’t known that the Kathleen & May, now on sale, was there too.

Kathleen & May

In Greenwich, I saw a bust of George Biddell Airy, late Astronomer Royal, whose work on the tides of the Shannon Estuary is of such great interest.

Grand Canal Harbour maltings: a protected structure

I see on this website that the curved building at Grand Canal Harbour in Dublin, is a protected structure.

Here is the roof in 2007:

Here is the roof in October 2011:

I have asked the developers for their comments.

 

The Broadstone

On a quick visit to Dublin, I managed to get a carless photo of the Broadstone MGWR station building.

Shannon estuary: Aughinish

The Irish Times reports that Rusal, current owners of the Aughinish Alumina plant, want to increase production. See the plant and its “waste storage facility” here (satellite view on a larger map is best):

Two more sisters

Members of the Heritage Boat Association have, in recent weeks, visited Piltown (Co Kilkenny) and Portlaw (Co Waterford) by barge, the first time in many years that large vessels have been up those rivers.

Many of the published accounts of Portlaw, including the Heritage Council’s Heritage Conservation Plan, pay inadequate attention to the navigation of the Clodiagh; it may have been even richer than we thought.

The HBA has a press release about some significant finds at Portlaw.

The owners of the barge Hawthorn joined other boats for the trips and wrote about them here:

Here is the relevant section of the OSI map for Portlaw (choose one of the Historic options). Here is where the Pil joins the Suir (zoomed out).

Here is my own article (in need of updating) about Portlaw and the Clodiagh.

Incidentally, I contend that the OSI maps are wrong in describing the gates on the canal as flood gates: they would open to, rather than close against, an incoming flood, and would prevent the discharge of an outgoing flood.

 

Cycling the Royal Canal

Here is a very short report from someone who did some of it (Dublin to Abbeyshrule).

Love me tender

Waterways Ireland tender documents are a source of interesting and occasionally useful information. At present WI is looking for tenders for

  • a hospitality guide
  • turf (sod peat) for bank repairs on the Royal Canal
  • automation of certain weirs. Expressing an interest in this one will allow you to get some original (Shannon Commissioners) drawings of parts of the  old weirs.
