Background Information

 

Oak Hill Park Local Nature Reserve is managed by London Wildlife Trust and is located in the London Borough of Barnet. A tributary of the Pymmes Brook flowed through the Reserve as a culvert which ran beneath the woodland & amenity grassland in the park, before entering the main river further down the site.

 

Scope of the Project

 

The aim of the project was to ‘daylight’ the tributary and create a wetland habitat throughout Oak Hill Park. Benefiting wildlife and reducing historic flooding of the open space The beginning of the culvert in the woods was to be blocked and the existing structure removed. The stream was then to be diverted into a newly dug channel throughout Oak Hill Park, before being connected back into the main channel of the Pymmes Brook at the bottom of the park. An additional wetland scrape adjacent to the newly dug channel would also be constructed so that the new stream can overtop into the wetland at times of high flow. All this was to be achieved in a busy North London Park with an emphasis on health and safety and minimal disruption to public access.

 

Our Solution

 

In the woodland area, an existing overflow streambed was used to form the start of the new channel. Where it exited the woodland a 180m meandering channel was excavated through the grassland within the park, reconnecting the watercourse to the Pymmes Brook. The Culvert was then blocked at the upstream end and the manhole structure was removed to eradicate all evidence of the once underground watercourse. Woody material was used from tree clearance works to create logjam step weirs that overcame the sites gradient.

Gravels were introduced along the length of the newly dug channel providing pool and riffle habitat that would also reduce erosion of the streambed. Alongside the new channel, a large wetland scrape was constructed to accommodate additional high flows and provide additional habitat within the parkland. The newly created stream and wetland were then planted with a mixture of native aquatic marginal plant species. Finally, several footbridges and a 10T vehicle crossing were built that allowed easy access for the public and maintenance staff to the other side of the park.

Great Mosque of Kairouan

It’s the biggest mosque in Tunisia & an impressive Islamic monuments in North Africa. Locals say that visit this great mosque 7 times, equals the visit to the holy city Mecca

Kairouan, Tunisia

Coordinates: 35.681400, 10.103900

The Great Mosque of Kairouan also known as the Mosque of Uqba, is a mosque situated in the UNESCO World Heritage town of Kairouan, Tunisia and is one of the largest mosque in country.

Established by the Arab general Hazrat Uqba ibn Nafi رضي الله عنه in the year 50 AH (670AD/CE) at the founding of the city of Kairouan, the mosque occupies an area of over 9,000 square metres (97,000 sq ft).

It is one of the oldest places of worship in the Islamic world, and is a model for all later mosques in the Maghreb.

Some say Kairouan is the 4th most crucial location in Islam. That may be subjective, however, the mosque is impressive. The exterior view is both formidable and beautiful and the interior has so much detail. If you are not Muslim, you will not have fill access but you can experience most aspects.

Hazrat Uqba ibn Nafi رضي الله عنه

Hazrat Uqba ibn Nafi رضي الله عنه was an Arab general serving the Rashidun Caliphate since the Reign of Hazrat Umar رضي الله عنه and later on the Umayyad Caliphate during the reigns of Hazrat Muawiyah I رضي الله عنه, leading the Muslim conquest of the Maghreb, including present-day Algeria, Tunisia, Libya and Morocco.

Hazrat Uqbah رضي الله عنه was the nephew of Hazrat Amr ibn al-As رضي الله عنه.

His descendants would be known as the ʿUqbids or Fihrids. Hazrat Uqbah رضي الله عنه is the founder of the cultural city of Kairouan in Tunisia.

Hazrat Uqbah رضي الله عنه accompanied Hazrat Amr رضي الله عنه in his initial capture of cities in North Africa starting with Barca, then proceeding to Tripolitania in 644.

In 670 now the emir or commander, Hazrat Uqba رضي الله عنه led an Arab army to North Africa, crossing the Egyptian deserts, and setting up military posts at regular intervals along his route.

In a region of what is now Tunisia, he established the town now called Kairouan (meaning “camp” or “caravanserai” in Persian) about 99 miles south of present-day Tunis, which he used as a base for further operations.

According to one legend, one of Hazrat Uqba رضي الله عنه’s soldiers stumbled across a golden goblet buried in the sands.

It was recognized as one that had disappeared from Mecca some years before, and when it was dug out of the sand a spring appeared, with waters said to come from the same source as those of the sacred Zamzam Well in Mecca.

This story led to Kairouan becoming a place of pilgrimage and then a holy city (“the Mecca of the Maghreb”) and the most important city in North Africa.

In 683 Hazrat Uqba رضي الله عنه was ambushed and killed by the Berber Christian king Kusaila in the Battle of Vescera.

He died beside his hated rival, Abu al-Muhajir Dinar. His armies evacuated Kairouan and withdrew to Barca, though it was recaptured in 688.
