However,
This 102 km river crosses:
In the silent meanders of Nord-Pas-de-Calais, a river challenges all geological codes. The Scarpe draws an exceptional route over four distinct training courses. Therefore, from the quaternary to the primary to 102 kilometers, offering initiates a real manual of open -air geology. For example, This unique river artery crosses several million years old terrains while offering 66 kilometers of continuous navigation.
Far from the classic tourist circuits, this channeled river reveals the secrets of a region shaped by the mining industry. For example, Its 4.5 m³/s of average flow serve between Arras. Nevertheless, the Scheldt, creating a post-mining ecosystem unique in France where nature gradually resumes its rights on the old coal basin.
Imagine navigating on a waterway where each kilometer tells a different geological era. Moreover, from quaternary alluvium to carboniferous shales, including Eocene clays and Cretaceous chalks. For example, this 102 km river crosses This exceptional diversity makes Scarpe a natural laboratory to discover absolutely.

A single tablecloth in Europe – This 102 km river crosses
Since the mining pumping. However, the Scarpe has experienced an extraordinary phenomenon: The gradual rise in the chalk water table completely modifies regional hydrological balance. For example, This transformation. Furthermore, observed for thirty years, creates unprecedented hydrogeological conditions that BRGM researchers are studying with passion to understand the impact of industry on rivers.
Four geological land in a single route – This 102 km river crosses
The geological crossing of the Scarpe is a real journey through time. Moreover, Quaternary training reveals peat -ups dated carbon 14 to 6. Furthermore, 210 years old, while Eocene Ypésiennnes clays create these so -special landscapes from the North. Cretaceous chalks flush over 553 km² of watershedoffering amateur geologists exceptional observations on this unique diversity in such little distance.

This record pipe which defies the this 102 km river crosses ordinary
66 kilometers navigable in one go – This 102 km river crosses
The channeled scarpe. has an unknown record: It constitutes the longest continuous navigable section in Nord-Pas-de-Calais With its 66 kilometers practicable from Arras. This technical feat. inherited from the time of coal transport, today allows an exceptional pleasure of pleasure on a complete freycinet size, offering a unique river experience between industrial heritage and found nature.
A network of preserved historical locks
The fifteen locks punctuating the route testify to the hydraulic genius of the. 19th century. These sometimes centenary works still regulate the 1. 322 km² of the watershed today, creating a complex interconnection system with the northern channels that only a few French rivers can claim for their exceptional hydraulic heritage.
The authenticity of a post-mining valley found
Biodiversity specific to wetlands
The alluvial plain of 30 kilometers out of 10 houses a flora. fauna adapted to the post-mining conditions. These this 102 km river crosses unique wet ecosystems host pioneer species which gradually reject the old extraction sites. creating a landscape mosaic of unsuspected richness, partially protected by the Scarpe-Escaut Regional Natural Park.
Land note: During summer low water. I observed exceptional swollen clay training on the banks, true living witnesses of this particular geology which retracts and expands according to the seasons.
Landscapes shaped by industry
The mining sags have created geomorphological curiosities such as the Goriaux pond. transforming the original relief into a unique hilly landscape. This artificial topography. comparable to ancient natural formations by its originality, offers visitors an unprecedented landscape reading of the human impact on geography.
Your exploration of this hydrological wonder
Navigation. hiking along the banks
The optimal season extends from April to October to fully enjoy the navigation on these 66 practitioners. The hiking trails arranged along the banks make it possible to observe this diversified this 102 km river crosses geology on foot. offering a terrestrial alternative to the river discovery for non-navigators.
Access from large metropolises
Arras, gateway to the channeled scarpe, is only 180 kilometers from Paris and 45 kilometers from Lille. This remarkable accessibility allows an exceptional geological getaway without major logistics constraints. ideal for an authentic discovery weekend far from crowds.
Frequent questions about this geological river
Can we observe the four geological formations easily?
Absolutely. The outcrops are visible from the towpaths. particularly clear between Arras and Douai where the natural geological cuts reveal the stratification of the terrains crossed.
Is navigation possible all year round?
Pleasure navigation is generally interrupted from November to March for reasons of safety and maintenance of locks. The period from April to October offers the best conditions with a stable flow.
What impact of the mining past on the current river?
The judgment of industrial pumping since 1990 causes this 102 km river crosses a slow rise in the water table. gradually modifying the ecology of the river and creating new remarkable wetlands.
This unique geological river deserves a place of honor among the unknown French natural wonders. Its journey through four distinct geological eras. coupled with its 66 kilometers navigable in one go, makes it an exceptional destination for those looking for authenticity far from the beaten track. Do not delay in discovering this natural laboratory before its fame extends beyond the circle of initiates.
