River Dargle Flood Defence Scheme.

Hard to believe - but I've been recording this project now for 5 years.
Most of the main civil engineering works have ceased along the Slang/Rehills section of the river bank.
However, the soil-shifters are at it again.
Smaller operation than before, but a steady process of removing soil, shifting soil and reshaping the banks.
You don't have to be a certified civil engineer to figure out that there are quicker and more efficient ways to move the soil.
Using one excavator, a few dumper-trucks and a single bulldozer is a process not driven by time/cost.
If you 'really' had to complete this work quickly, you'd line up a few 'bigboy' bulldozers . . . . . and shift the soil in days, rather than weeks-months.
This 'hurdler on the ditch' simply comments on the piecemeal nature of this planning!
Maybe they're eavesdropping . . . but, suddenly, man-mountains disappear, and level expanses appear.
Along this strip of the riverbank, they are landscaping a strip of land, installing public seating and creating picnic area.
The pedestrian tracks running around are called 'Hoggin paths'.
Nice idea. I hope it is properly used and well maintained.
Hard to believe - but I've been recording this project now for 5 years.
================================================
'Hoggin' is a compactable groundcover that is composed of a mixture of clay, gravel, and sand or granite dust that produces a buff-coloured bound surface.
The material is aesthetically suited to older properties and is lower maintenance than gravel alone since it does not need regular raking. Once laid, the surface is somewhat permeable to water and therefore does not easily hold puddles or generate rapid surface runoff.
The material is increasingly being used at domestic properties as a low cost and environmentally friendly alternative to concrete and block paving in paths and driveways.
A compacted sub-base of larger crushed stone is often laid prior to the top layer of hoggin, especially if the area to be covered is soft ground, or prone to puddling.
The larger rocks provide a firm base for the hoggin, and improved drainage.

River Dargle Flood Defence Scheme.
These images were taken during the first week of October 2012, tracking the on-going river bank alterations and excavation of the river bed.
In preparation for the river-bank strengthening/protection along this stretch of the river, a 2nd channel was created -- with the intention of diverting the river.
Having endured a similar flooding only days earlier, another heavy fall of rain caused the channels to fill up again.
It meant starting all over again - draining this road/bank side channel, cutting a release channel near the bridge to release the volume, and activating pumps to assist with the repeated drainage.
Matters were never helped by the overflow pipe which siphoned run-off from the adjacent motorway!
Always quite amazing to see how water levels could drain away within a few days.
The question would always be -- how much work could be completed before the (inevitable) next run of water?
As we can see, one or two day's intense rain could produce rapid flooding of channels, swamping on-going works, and causing temporary vehicle access paths to have to be repaired. And these access ramps were proving difficult to navigate for the fully-laden dumpers/trucks.
One hell of a wet and messy place to be working, especially for the guys on foot.
Gabions consist of steel ‘baskets’ filled with rock pieces.
They are filled and then fixed together to provide protection and strength to the existing river bank.
They allow ground water to flow through them which helps prevent waterlogging of the bank behind them. Existing examples of these can be seen (here) on the North bank to the rear of the La Vallee Apartments.
Long shallow versions of gabions, known as ‘mattresses’, are used to protect the edges of the river channel, particularly at bends in the river.

Hailed as a great feat of civil engineering at the time of its completion in 1907, the Silver Lake Reservoir Complex was built on land that the city of Los Angeles began acquiring through eminent domain in the 1880's. Chief Engineer William Mulholland utilized an innovative design (later adapted for use in building the Panama Canal) known as 'sluicing', utilizing hydraulic pumps to remove material from the lake's bottom, which was recycled to form the dam. At the time of their completion, the two reservoirs were the only drinking water storage facility west of the San Andreas Fault designed for emergency use in the event of a failure in the aqueduct system. Mulholland stocked the reservoir with Black Bass to 'keep minnows from clogging the pipes or swimming through the system into the bath. He personally chose the day each year to declare open fishing season', according to the Committee to Save Silver Lake's Reservoirs website, www.csslr.org. By 1912, the complex had been landscaped with thousands of trees by the Los Angeles Parks Commission and was a great source of civic pride.
The 127-acre site is named for Herman Silver (and not in reference to its shimmering waters), a member of Los Angeles' first Board of Water Commissioners. It is currently operated by the L.A. Department of Water & Power, with 96 acres of open water and paved roads, and 23 acres of open space, 'home' to native Angelino fauna such as coyotes, racoons, skunks and birds, including the Great Blue Heron.
In 1989, the reservoir complex was designated an Historic-Cultural Monument by the City of Los Angeles Cultural Heritage Commission (No. 422), a designation which allows for significant public scrutiny in the event of proposed changes to the site. This photo was taken from the upstairs window of the historic John R. Hunt House located at 2055 West Silver Lake Drivel.

Adjacent to The People's Park, a large compound is the site of continuing work along this section of the river. Some of the works are nearing completion.
Access is quite restricted here, and involves shipping material in/out via the entrance further upriver, adjacent to The Slang.
A temporary soil shelf was laid along this wall-side, to allow better access for vehicles moving materials in and out.
In the compound itself, quite empty of mechanical vehicles these days, we see some running repairs on a triple-axle flatbed trailer -- tipped on it's side with the assistance of an excavator.
The Ypsilanti Water Tower, commonly referred to as the "Brick Dick," was completed in 1890. The stone structure is listed both on the state register and the National Register of Historic Places. It is also an American Water Landmark, and a Historic Civil Engineering Landmark. In 2003 Cabinet Magazine named it the world's most phallic building.

Said it before, and I'll say it again . . . . .
I call it the 'Biggest Sandpit/Playarea' in Wicklow, in Leinster, in Ireland.
The place is a mess. Aesthetically, the uneven flow to the ridges and terraces annoys me.

The Forth Bridge is a masterpiece of railway civil engineering, an iconic landmark, a milestone in the development of railways, the first major structure in Britain to be made of steel and its completion created a single continuous railway line from London to Aberdeen.
The first rail crossing here was made in 1850 when the Edinburgh, Leith and Granton Railway started the world’s first ‘train ferry’ - designed by Thomas Bouch - between Granton and Burntisland. In August 1873 Bouch was instructed by the North British Railway to build a suspension bridge across the Firth of Forth. Construction began in 1878 but when Bouch’s original Tay Bridge collapsed during a storm in December 1879, work immediately stopped and never restarted.
Designs for a new bridge to cross the Forth between South and North Queensferry were invited by the newly formed Forth Bridge Railway Company which had been formed jointly by the North British, the Midland, the North Eastern and Great Northern railways, The design had to conform to specifications from both the admiralty who stipulated that the Forth remained a navigable channel, and the Board of Trade who stipulated, following the Tay bridge collapse, that the bridge must be rigid, stiff and capable of carrying the heaviest freight trains.
John Fowler and Benjamin Baker were engaged to develop their cantilevered design for the bridge while the contract for the construction was let to Sir William Arrol & Co with work on the bridge starting in 1883.
Construction of the 1.6 mile long bridge took 6 years, 55,000 tonnes of steel, 173000ft³ of concrete, 50t of cement, 640,000ft³, of granite, 8 million rivets and the lives of 73 of the 4600 men who worked on the site. The bridge was built in two phases. The first, from 1882 to 1885, involved enabling works, including sinking the caissons and constructing the foundations and piers to support the superstructure. The superstructure, which weighs about 51,324t, was built from 1886 to 1890.
The Forth Bridge has three double cantilevers, 330ft tall & 680ft long, with two 1700ft suspended sections between them. As required by the Admiralty, the rail level is 151ft above the river. Each of the towers has four steel tubes, 12ft in diameter, which reach to a height of 361ft above the water. The foundations extend 89ft below the bridge into the river bed, making the total height from foundations to the top of the towers 450ft. Each tower rests on separate granite pier constructed by 70 ft diameter caissons which used compressed air to keep water out of the working chamber at the base
In recent years a £130m refurbishment programme has been undertaken that has seen the whole bridge repaired and repainted. The paintwork was sand blasted back to bare metal and any damaged steelwork repaired before the new paint was applied. The techniques and epoxy based paint used means that the bridge will not require a full repaint for at least 20 years, finally putting an end to the myth that “painting the Forth Bridge” is a never ending task!

Long shallow versions of gabions, known as ‘mattresses’, are used to protect the edges of the river channel, particularly at bends in the river.
At this section of the river, behind the La Vallee Apartments, the guys are continuing the bank protection work: rolling down strips of membrane, prior to being stapled into the bank. This is a slightly less complicated process to that used on the higher/steeper slopes further up-river, where they drilled/filled 6-foot hollow tubes into the faces of the bank.
