Analysis of existing water information for the applicability of water quality indices in the fluvial-littoral area of turia and Jucar Rivers, valencia, Spain

摘要

For the first time, all the water quality information gathered by an European Union water district authority between 1990 and 2016 (the Spanish Jucar River Management Authority, Confederacion Hidrografica del Jucar, CHJ) was analysed and discussed. The main goal is to evaluate the applicability of this existing physicochemical information as potential data sources for continuous evaluation with Water Quality Indices (WQIs). Specifically, the spatial and temporal representativity of available data is assessed together with the applicability of WQIs both in time and space. A list of 42 existing WQIs with type and number of variables used was compiled after literature review. The study was carried out in the fluvial-littoral area of Turia and Jucar Rivers, Valencia, Spain, which was divided into six Landscape Functional Areas (LFAs), based on the outer continental perimeter zone, the irrigation areas of main channels crossing the flood plain, and the Albufera Lake.
