Seasonal water quality trends in the lower Segre river-derived channels (NE Spain)

Abstract

Comunicació presentada al Congress on Industrial and Agricultural Canals. Lleida, 2014

A monthly sampling survey has been undertaken in the main agricultural and industrial channels derived from the Lower Segre River system (Eastern Ebro Basin, NE Spain) during 2009 and 2010. The monthly evolution of the chemical water quality has been monitored in 11 benchmark spots of the Canals d’Urgell, Auxiliar d’Urgell, Balaguer, Gerb, Hostal Nou, Cup, Aragó i Catalunya, and Serós channels. At the Canals d’Urgell system, the 2nd, 3rd and 4th derivations as well as the final stretch have been controlled. The goal of the survey is to assess physical, chemical and biological water properties with the objective of diagnosing its water quality status according to the Water Framework Directive (2000/60/CE) and to point out actions to improve this channel system.
