DescriptionArgon-Field-katavothra Peloponnese Greece.jpg |
Ελληνικά: Το μοναδικό καταβόθρα (English: ponor) του μήκους περίπου 5 Χμ πολπε „Αργόν Πεδίον“ πήρε το όνομά του από τον Παυσανίας (160 μ. Χρ.). Μερικές φορές πολύ άφθονη βροχόπτωση τροφοδοτείται στο καταβόθρα μέσω μιας σειράς τάφρων αποστράγγισης στο κοίλο σχήμα του καρστικού τοπίου, το οποίο είναι κλειστό από όλες τις πλευρές. Μετά από περίπου 30 χμ σε υπόγειες πλωτές οδούς, το νερό επανεμφανίζεται σε μια πολύ μεγάλη υποθαλάσσια πηγή "Ανάβαλος" ακριβώς στην παραλιακή άκρη του Αργολικού Κόλπου. Οι κάτοικοι του χωριού Νεστάνη, στο νότιο άκρο Άγρον Πεδίον, αφήνουν τα κοπάδια των αιγοπροβάτων να βόσκουν στα βοσκοτόπια τους.
English: Single Ponor of a ca. 5 km long polje. The polje’s name Argón Pedíon (“untilled field”) is preserved in the book “Description of Greece, Book 8, Arcadia” (ca. 160 A.D.), Pausanias. The polje has no surface outflow.
A row of drainage ditches and meandering furrows drain the plain, unless precipitation was so excessive that a temporary lake forms. The ponor’s run-off, whether inhibited by debris or even clogged, determinates the lake’s disappearance. After ca. 30 km, subsurface, the waters emerge again in a large coastal spring called “Anavalos”. Deutsch: Einziger Ponor einer ca. 5 km langen Polje. Die Polje wurde schon von dem antiken Schriftsteller ]Pausanias (ca. 160 AD) in seinen Dokumenten „Beschreibung Griechenlands, Buch VIII Arkadien“ überliefert. Er nannte die Polje „Argón Pedíon“ („Faules Feld“). Zuweilen zu reichlich anfallende Niederschläge werden in der allseits geschlossenen Karst-Hohlform dann als temporärer See gespeichert und in einer natürlichen Furche und einer Reihe Entwässerungsgräben dem Ponor - dessen jeweiliger Abflussleistung gemäß – zugeführt. Nach ca. 30 km, unterirdisch, kommt das Wasser in einer sehr großen Unterseeischen Quelle („Dine“), unmittelbar am Küstensaum des Argolischen Golfs wieder ans Tageslicht.
