Ibaia motza eta malkartsua da, %2,1ko bataz besteko aldaparekin. Itsasorako bere 62,4 kilometrotako bidean Eskoriatza, Aretxabaleta, Arrasate, Bergara, Soraluze, Elgoibar, Mendaro eta Mutrikuko udalerriak zeharkatzen ditu. Arroak 518 km2 hartzen du.
Ezkerraldeko ibaiadar nagusiak Aramaio, Angiozar, Aranerreka, Ego (Eibarko ibaiadar nagusia) eta Kilimon (Mendaro) dira. Eskuinaldekoak, aldiz, Oñati, Urkulu eta Antzuola ibaiak.
Debarroa betidanik erabili izan da Gaztela eta itsasoa Arabatik lotzeko. Erromatarren garaian, bazegoen bidea Veleia (Gasteizen ondoan) eta Tritium Tiboricum (Astigarribia, Deba ondoan) lotzen zuena.
Ertarotik aurrera Gaztelako artilea ere Debarrotik itsasoratzen zen: Altzolaraino gurdiz eta handik, alatan[2], Debako porturaino. Eta bide bera erabiltzen zen Soraluzetik Debara fusilak, arkabuzak eta gainontzeko armak eramateko.
XVIII. mendean, Argien mendean zehar, Mediterraneoa eta Atlantikoa Zadorra eta Deba ibaien bidez elkar lotzeko egitasmoa planteatu zen. 1776 eta 1790 artean Frantzisko Xabier Muniberen[3] aginduz zati batzuk egin bazituzten ere, proiektua ez zuten gauzatu ahal izan orografia zailak diru asko eskatzen zuelako.
XX mendeko bigarren erdialdean Deba ibaia bihurtu zen Europako ibai kutsatueneko bat, kutsatuena ez bazen. Bertako industria izandako garapena alde batetik, eta garai hartako kutsadurarekiko ezaxolatasuna bestetik, egoera tamalgarrian jarri zuten ibaia. Soraluze ez zen salbuespena: Bergara aldetik zetorkion kutsadura jasatzeaz gain, bertako lantegiek kutsadura gehiago eransten zion ibaiari.
1980 hamarkadatik aurrera egoera bideratzen ari da: herrietako ur-araztaileak, lantegietakoak… Hala ere, oraindik asko geratzen da ibaia lehengoratzeko.

Deba ibaiak Soraluzeko udalerria zeharkatzen du, hegoaldetik iparraldera. Bertako hidrografiaren ardatza da.
Bere bost kilometroetako ibilbidea oso laua da, hogetabost bat metro galtzen dituela. Hala ere, altura alde hori nahikoa izan zen hainbat presa eraikitzeko: Alberdi, Ibaizabal, Olabarrena…
Ibaiak Soraluzeko herriari bere itxura ematen dio, herria bere hertzetan eraikia baitago. Soraluzeko tarteak 5 km ditu, eta horietan 35 bat metro jaisten da (110 metrotatik 75 metrotara) eta 20-25 metrotako zabalera du leku gehienetan.
Hiru gune nagusitan banatu daiteke ibaiaren arroa herrian:
a) Deba Ibaia
b) Sagar-Erreka
c) Bigarren mailako ibai adarrak.
