Озеро Гижгит находится в Баксанском ущелье Кабардино-Балкарии, недалеко от поселка Былым. Взглянув на озеро, сложно представить, что подобная красота является рукотворной, и к сожалению, даже таит в себе угрозу.
Строго говоря, озеро Гижгит совсем не озеро, а запруда одноименной реки. Дело в том, что в 1940-2000 годы примерно в 10 км от этого места рядом с г. Тырныауз действовал Тырныаузский горно-обогатительный комбинат (ТГОК), специализирующийся на добыче и обогащении вольфрамо-молибденовых руд. В 1966 году в русле реки Гижгит, которая является притоком бурной горной реки Баксан, для нужд ТГОК было построено третье (основное) хвостохранилище, или, если говорить проще, отстойник токсичных отходов производства. Устье реки было перегорожено плотиной, в результате чего в русле горной реки образовалось водохранилище, называемое сейчас озером. Сток воды из озера Гижгит осуществляется по специальному отводному тоннелю в реку Баксан.
Хвосты — профессиональный термин, обозначающий отходы производства руды, зачастую токсичные. Хвостами называют токсичные отходы обогащения полезных ископаемых, соответственно хвостохранилище – комплекс специальных сооружений, предназначенный для их хранения и захоронения.
В годы работы комбината в хвостохранилище по десятикилометровому трубопроводу поступали отходы обогащения вольфрамового, молибденового и медно-висмутового концентратов. Около 30 наименований химических соединений металлов, каждый из которых в сильных концентрациях смертельно опасен для здоровья человека и животных. По различным оценкам, с 1966 по 2001 год тут было захоронено от 25 до 118 млн кубических метров отходов.
В настоящее время трубопровод демонтирован, но отходы остаются в озере. Уровень воды в нем поддерживается при помощи сбросного колодца для водопонижения и водоотведения, связанного с водоотводным каналом, соединяющим озеро с Баксаном. Считается, что отходы на дне озера слиплись практически до состояния цемента.
В 2018 году на страницах научно-технического журнала "Вестник МГСУ" группой ученых (К.А. Гегиев, А.Х. Шерхов, З.Ж. Гергокова и К.К. Анахаев) была опубликована статья под названием "Экологические проблемы Тырныаузского хвостохранилища на реке Гижгит", в которой подробно описана опасность, исходящая от бывшего хранилища ядовитых отходов:
"В обогащенных отходах содержатся до 30 наименований химических соединений металлов (в т.ч. высокого класса опасности), которые с поверхности пляжа хвостохранилища в виде пылеватых облаков переносятся постоянно дующими вдоль долины р. Баксан ветрами (Тырны-Ауз в переводе с балкарского языка «ущелье ветров») на прилегающие к ним сельхозугодья и природные пастбища..."
Гижгит — река в России, протекает в Эльбрусском районе Кабардино-Балкарской Республики. Длина реки составляет 28 км. В низовьях запружена, образует водохранилище-хвостохранилище Тырнаузского горно-обогатительного комбината. В самом низовье протекает по искусственному тоннелю до места впадения в реку Баксан. Устье реки находится в 112 км по левому берегу реки Баксан.
The Falkirk Wheel is a unique boat lift in the world. It replaces a series of 11 locks linking the canals from Glasgow to Edinburgh. The Falkirk rotary lift has a diameter of 35 metres and lowers or raises ships to a height of 25 metres. A set of double doors allows the boat to enter on one side and to leave on the other side. The wheel turns the two caissons, each weighing 300 tonnes, while the gearing system keeps them perfectly horizontal.
This steam engine is a real vintage among vintages. Made by Fowler and Company in Leeds, England in 1880, it has been perfectly restored to its former glory. This is a close up of the engine that was pulling the trailer in my previous shot.
"Wheels within wheels..." Notice that flywheel turning.
This detail of the little engine, "Wee Georgie Wood", shows how beautifully cared for it is. Precision engineering at its best, the full flowering of the industrial revolution.
I found no way to produce a b&w version without losing the complete mood, so I'm very very sorry, but I can show you only the colored version... ;)
Zeeland Bridge.
The longest bridge in the Netherlands.

This is in the back garden of the house we have lived in for about 40 years, and this is first time I have noticed the manufacturer's name on the manhole cover (unless I've seen it before and forgotten).
One of the most vivid memories I have from my primary school years was visiting the Dover Engineering Works with my school. It's not surprising that seeing molten iron poured from a ladle into a mould from close quarters would make a lasting impression on a child. I can still see clearly in my mind the wooden pattern they had made of our school's badge being pressed into the compacted black sandy material in the mould. The pattern was then removed and the top half of the mould filled with more compacted material was fitted. Small holes to allow the escape of burning gas were made in the material. When the molten iron was poured into the mould, sure enough, jets of flame appeared from these holes. When the mould was eventually stripped, there was the grey/silver replica of the wooden pattern.
When the company was established in 1830 it was on the outskirts of Dover in the parish of Charlton, with a supply of water from the adjacent River Dour. Charlton has since been absorbed by Dover, and the engineering works is of course gone - with the site now occupied by a supermarket.
Department of Engineering, University of Cambridge. Not happy with this one, but will have to do for now as I wanted a general shot of the department building and I did find the staircase interesting!
Long Island Rail Road (LIRR) engineering inspection vehicle TC82, manufactured by Plasser, is seen crossing Borden Ave in Long Island City, Queens as it starts an inspection run back out to points east. This is clearly an unusual sight, as even other rail road employees at the adjacent facility are looking on!

For the Pessimist, the glass is half empty.
For the Optimist the glass is half full.
For the Engineer, the glass is twice as big as it needs to be.

The engineering marvel of Ribbleshead Viaduct pales into insignificance as darkness falls on a clear summer night.
Standing outside this century old barn, I looked up to see an aircraft flying overhead and thought of how far we'd come. The barn featured a unique swing beam construction that allowed a team of horses, hitched to a wagon, to turn around without having to back up. Horses apparently don't like to walk backwards so this made life easier for farmer and animal alike. When you compare that marvel of practical engineering to the complexity of the plane, it seems there are no limits to what we can accomplish.
I love birds nests, the engineering that goes on is akin to a messy hairdo or tangled fishing lines. I just hope Mrs Thrush or Blackbird had finished with it. The base of the nest is set like concrete and full of a fluffy substance. Clever animals. ISO 640 1/10 sec. f/11 200 mm.
Concorde, at the Aviation Viewing Platform at Manchester Airport. The construction you can see at the right of the photo will eventually house this fantastic aircraft.
My second entry in this months competition on Bridges.
Had a few days away in Bristol so couldn't really visit without seeing and taking an image of the magnificent Clifton Suspension Bridge.
It spans the river Avon and has a remarkable history which is well worth reading about.
The original design was of Isambard Kingdom Brunel .
Spanning over 702 ft and 249ft above the Avon it had the longest span of any bridge in the world at the time of its construction.
Thank you for viewing and any comments
Completed in 1965, Carson Engineering Center was opened for use during the 75th anniversary celebration of the University of Oklahoma. Designed to house the growing College of Engineering, the facility effectively doubled the space available for engineering programs. The building was originally called the Engineering Center, but was renamed for William H. Carson, the second dean of the College, upon his death in the early 1970’s.

The warm glow from a setting sun is reflected off the concrete spillway cells of the Murray Lock & Dam. The dam sits under the Big Dam Bridge on the Arkansas River in Little Rock. The dam & lock is part of a series of similar structures to facilitate commercial vessel navigation on the Arkansas River all the way up to Tulsa, OK.
