Impact du changement climatique sur les régimes hydrologiques des cantons du Jura et de Neuchâtel

2025

Abstract

Ce travail s’intéresse aux conséquences du changement climatique actuel sur les régimes hydrologiques. L’objectif est d’identifier les impacts attendus sur les débits, et ce, principalement pour les débits extrêmes (étiage et crue). Pour les bassins versants des cantons du Jura et de Neuchâtel en Suisse, des modèles Pluie-Débit ont été créés, calibrés et validés. Ils ont permis de constituer des jeux de données de débits futurs (1981-2099) pour trois scénarios d’émissions (RCP2.6, RCP4.5 et RCP8.5). Ce travail révèle une diminution des débits d’étiage d’ici à la fin du siècle, et ce, principalement sous le scénario d’émission RCP8.5. L’impact du changement climatique sur les crues n’a pas pu être décelé avec cette méthodologie. Cela est principalement dû au pas de temps journalier des jeux de données utilisés et créés. Finalement, la diminution du stock d’eau sous forme de neige et de glace provoque un décalage saisonnier dans l’apparition des événements d’étiage et de crue.

Neuchâtel

Neuchâtel (UKˌnɜːʃæˈtɛl, US-ʃɑːˈ-,_ˌnjuːʃəˈ-,_ˌnʊʃɑːˈ-, nøʃɑtɛl; Neuenburg) is a town, a municipality, and the capital of the Swiss canton of Neuchâtel on Lake Neuchâtel. Since the fusion in 2021 of the municipalities of Neuchâtel, Corcelles-Cormondrèche, Peseux, and Valangin, the city has approximately 33,000 inhabitants (80,000 in the metropolitan area). The city is sometimes referred to historically by the German name Neuenburg; both the French and German names mean "New Castle".

Canton of Neuchâtel

The Republic and Canton of Neuchâtel (République et Canton de Neuchâtel) is a French-speaking canton in western Switzerland. In 2007, its population was 169,782, of whom 39,654 (or 23.4%) were foreigners. The capital is Neuchâtel. The only part of present-day Switzerland to enter the Confederation as a principality (on May 19, 1815), Neuchâtel has a unique history. Its first recorded ruler, Rudolph III of Burgundy, mentioned Neuchâtel in his will in 1032. The dynasty of Ulrich count of Fenis (Hasenburg) took over the town and its territories in 1034.

Romandy

Romandy (Romandie or Suisse romande) is the French-speaking part of Switzerland. In 2020, about 2 million people, or 22.8% of the Swiss population, lived in Romandy. The majority of the romand population lives in the western part of the country, especially the Arc Lémanique region along Lake Geneva, connecting Geneva, Vaud and the Lower Valais. French is the sole official language in four Swiss cantons: Geneva, Vaud, Neuchâtel, and Jura. Additionally, French and German have co-official status in three cantons: Fribourg/Freiburg, Valais/Wallis, and Berne/Bern.
