Plate 7.3 Temperature in Rivers and Lakes

Abstract

La température d’un cours d’eau, ou d’un lac, dépend avant tout de la température de l’air et du rayonnement solaire. On observe ainsi la superposition de plusieurs types de fluctuations de la température de l’eau. La suite chronologique des valeurs de la température de pratiquement tous les cours d’eau, et des lacs à faible profondeur, dessine une sinusoïde bien visible. Ce modèle sinusoïdal permet d’évaluer, en particulier, la température que l’on devrait pouvoir mesurer, en moyenne, à tel ou tel moment de l’année.

Le temperature delle acque superficiali dipendono in larga misura dalla temperatura atmosferica e dall’irraggiamento solare. Si osservano modalità di fluttuazione diverse e sovrapposte. Il decorso stagionale delle temperature nei corsi d’acqua e negli strati superiori dei laghi evidenzia una curva sinusoidale. Il modello della curva sinusoidale consente di calcolare la temperatura media attesa di un giorno qualunque dell’anno. 

Die Temperaturen der Oberflächengewässer sind stark von der Lufttemperatur und der Sonneneinstrahlung abhängig. Man beobachtet verschiedene, sich überlagernde Schwankungsarten. Der saisonale Verlauf der Temperaturen in Fliessgewässern und in den oberen Schichten von Seen zeigt eine deutliche Sinuskurve. Das Sinuskurvenmodell erlaubt es, die mittlere zu erwartende Temperatur an irgendeinem Tag im Jahr zu berechnen.

The temperature in a river or a lake depends strongly on the air temperature and the solar radiation. Several overlapping patterns of variation can be observed. The seasonal pattern of temperatures in rivers and in the upper layers of water in lakes shows a clear sinusoidal shape. Using the sine curve model it is possible to calculate the mean temperature to be expected on any one day of the year.
