Hierbij doe ik, Abe Hoekstra (oud-medewerker van Het Waterloopkundig Laboratorium van 1966-1996),
een poging om een deel van de geschiedenis van het Waterloopkundig Laboratorium "De Voorst" in de Noordoostpolder vast te leggen.
Het Waterloopkundig Laboratorium heeft een deel van het Voorsterbos in gebruik gehad vanaf 1951 voor het doen van modelonderzoek
en heeft dit terrein verlaten in 1996. Dit deel van het bos is nu vooral bekend onder de naam Waterloopbos.

Op pad met "de Heer van de Waterweg"

In het Voorsterbos in de Noordoostpolder werden waterwerken uitgetest op schaal.
Tot de ingenieurs verdwenen, en de modellen overwoekerd raakten.
Langzaam maar zeker wordt het bos weer in ere hersteld. Kennislink ging kijken.

In 1996 verlieten de ingenieurs en medewerkers het Voorsterbos.
De nieuwe eigenaar was een projectontwikkelaar die er een bungalowpark van wilde maken.
Maar dat ging gelukkig niet door, vertelt Ton van der Meulen. In 2002 ging het bos, met behulp van geld van de Postcodeloterij,
over in handen van Natuurmonumenten. In 2005 ging het open voor publiek. Inmiddels staat het Waterloopbos op de voorlopige lijst
van Rijksmonumenten uit de opbouwperiode van 1959 tot 1965.
De definitieve plaatsing zal vermoedelijk dit jaar zijn beslag krijgen, denkt Van der Meulen.
En dan kunnen er eindelijk plannen gemaakt worden om de bouwwerken in het bos te restaureren.

TIMELINE - PATS - 1967 - 2017


Did start on 01 Aug 1967 at this inspiring location till 01 Oct 1996 with WL
..... and I'm still there from 1996 as PATS ;)

- days - at this inspiring location

* * * 1967 - 1971 * * *

On August 1st, 1967 I, Teunis Schuurman a.k.a. PATS
did start at Het Waterloopkundig Laboratorium (WL|Delft Hydrauclics)
after I got my MULO-B diploma prior to that in June 1967
First based at the tiny office "Nieuwe-Waterwegkeet" with Ir. Ton van der Meulen and Ir. Wijnand Hendrik Tutuarima

I was assistant a.k.a. "rekenaar" on M 849 (Europoort) - Europoortloods-Modelplaats 16 (Mp16) together with Roelof Hulleman as "modelarbeider"
Later on the models on Mp6 behind the "Timmerwerkplaats" - known as M 936 (Duinafslag door stormgolven (1966)) and M 963 (Vlissingen)

The slide rule, or slipstick, is a mechanical analog computer
Rekenliniaal
Rekenliniaal - Ahrend . . . . . First computer without harddisk, memory and back-up :) . . . . .
Used for crunching the numbers, in the mid 70's replaced by a handheld HP-calculator on rental base (later permanent)

A follow-up M 918 - Fundamenteel onderzoek werking strandhoofden (1968) (Modelplaats 18 - Mp18) - was located more to the west,
along the bicycle-track, just after de Nieuwe-Maas model M 998 (Modelplaats 12 - Mp12) - with Johannes Dikken as "modelarbeider"
M 998 was from the other division "Rivieren en Scheepvaart", my division was "Havens en Kusten"

Ep Visscher and Klaas ten Napel "Grote Klaas" are names I do remember from those early days,
there are way more, like several "pratikanten" which were there only for a few months
as being on those models for Modelplaats 6 - Mp6, etc ... in that first period of Aug 1967 - Sep 1971
Ir. Kees Hulsbergen did start on March 1968 (first office was "Waterwegkeet")
