A little bit more about Anderlecht - one of the 19 municipalities of Brussels (and one of the most south) https://en.wikipedia.org/wiki/Anderlecht

Rivers and canals Where water finds it's way as wel as fish, humans, boats and beasts, animals where it exceeds, crosses, meanders, evades

natural riverbeds have their own dynamics human intervention modifies this yet there are processes that do not abide these adjustments or these choices have unexpected consequences

We are going to follow a few of these trajectories, for as long as we can

• because they contain a lot of information
• because of the random factor
• because these structures are bypassed of used unexpectedly or even improperly (what is proper/improper anyway)
• because you run into surprises

link with data

• in computing - The physical paths are determined - infrastructure
• what you can do on them/with them is pretty much predetermined
• we are interested in stepping over the lines (Dutch - buiten de lijntjes kleuren - colouring outside of the lines)
• reversing processes - contaminating
• the unexpected - the improper?

1. Take the metro to Ceria Coovi
2. Walk along the Chaussee the Mons
3. go into the Vogelzang nature reserve on the left
4. walk to the end of it
5. take one step in Negenmanneke - Flanders, turn and proceed to the Zuunstraat - Rue de Zuen towards the canal

1. For a large part we followed this trajectory, of this walk: pdf (nl) or pdf (fr)

• historical monument Farm of Dukes of Aa - photograph
• ceria coovi not
• Centre d'Enseignement et de Recherches des Industries Alimentaires et Chimiques = Centrum voor Onderricht en Opzoekingen der Voedings- en chemische Industrie
• from metro to small piece of Groene Wandeling/promenade verte
• from allotment gardens to the canal
• allotments - between Drogenbos cooling tower, ikea, coca cola, new depot petits riens, big companies with construction material, concrete etc
• gardeners already 17 years there - unclear status (no status)
• big dog club
• a few houses
• along the canal, under the ringroad highway

1827 - 1832 - canal is dug - canal charleroi-Brussels what we think to be one canal, is actually at least two connects to; Canal du Centre (Seneffe), seacanal Brussel-Schelde (escaut) (Brussel), de Samber (Charleroi)

Ronquières Inclined Plane (Plan incliné de Ronquières ) replaces 14 locks The Ronquières Inclined Plane has a length of 1,432 metres (4,698 ft) and lifts boats through 67.73 metres (222.2 ft)[2] vertically. It consists of two large caissons mounted on rails. Each caisson measures 91 metres (299 ft) long by 12 metres (39 ft) wide and has a water depth between 3 and 3.70 metres (9.8 and 12.1 ft). It can carry one boat of 1,350 tonnes or many smaller boats within the same limits. Each caisson has a 5,200-tonne counterweight running in the trough below the rails, which permits the caisson to be moved independently of the other.[2] Each caisson is pulled by 8 cables wound by winches located at the top end of the inclined plane. Each cable is 1,480 metres (4,860 ft) long. Each caisson can be moved between the two canal levels at a speed of 1.2 metres per second (3.9 ft/s), taking about 22 minutes. It takes 50 minutes in total to pass through the 1,800 metres (5,900 ft) of the entire structure, including the raised canal bridge at the top end.[2] https://en.wikipedia.org/wiki/Ronqui%C3%A8res_inclined_plane http://ronquieres.org/

(there's also a boat lift https://en.wikipedia.org/wiki/Str%C3%A9py-Thieu_boat_lift - http://voiesdeau.hainaut.be/tourisme/voiesdeauhainaut/fr/template/template.asp?page=stgpes2013fr&navcont=66,0,0

• fisherman (only since 2010) –> types of fish
  • cyprinids = voorn = certains types de carpe
  • common bream = brasem = breme commune
  • northern pike = snoek = grand brochet
  • zander = snoekbaars = sandre
  • european eal = paling = anguille d'europe
  • ide==orfe = de winde = ide melanote
• highspeedcyclists –> speedlimit (thus minister weyts) = 30km per hour
• leisure cyclists
• walking
• industry stuff in the boats (city as the mine of the future)

we pass by the Marina - sports & restaurant

In software, a stack overflow occurs if the stack pointer exceeds the stack bound. The call stack may consist of a limited amount of address space, often determined at the start of the program. The size of the call stack depends on many factors, including the programming language, machine architecture, multi-threading, and amount of available memory. When a program attempts to use more space than is available on the call stack (that is, when it attempts to access memory beyond the call stack's bounds, which is essentially a buffer overflow), the stack is said to overflow, typically resulting in a program crash

• too much water
• meet the Zenne
• again free space –> gardens
• picturesque picknick table in between industry zones and the railway line
• look at the Zenne fork (go over - and spot the industry Zone)

What water sources interact with the canal and the river? http://www.coordinatiezenne.be/mailer/Zennekrant_14/img/SPW.pdf

• old textile industry
• Italian restaurant
• wool mill Daoust –> Aa mills
• eerie

• main entry point to get into Brussels (and out of it)
• daily traffic jams
• Zenne at gas station - http://www.openstreetmap.org/?mlat=50.82284&mlon=4.30773#map=19/50.82284/4.30773&layers=N

8 zone pipi - yet fresh prunes and grapes - remnant of the past?

• industry again
• cross paepsem

follow till we can't anymore? or go back?

part 6 - going underground
