“…Our models derived from compulsory monitoring programmes (e.g. Munné et al, 2015) feature relatively poor relationships with a lot of noise remaining unexplained. Thus, this approach should be considered to offer initial conceptual understanding of ecosystem behaviour allowing managers to systematically go beyond the primary stressor approach to consider adaptive responses to future climate change and nutrient enrichment (Pullin and Knight, 2009;Ryder et al, 2010).…”

“…Over the years, many different methods of hydromorphological valorization of rivers have been developed. The La ¨nderarbeitsgemeinschaft Wasser (LAWA-vor-Ort) is considered the most refined [98]-German system and Systemed'Evaluation de la Qualite ´du Milieu Physique (SEQ-MP)-French system [99]. Particular systems differ in the number and type of registered morphological elements and in the field research procedure.…”

Current river assessment methods focus on evaluating a single aspect (e.g. the physical and chemical quality of the water or its hydromorphological state) and usually do not integrate various factors. The lack of an interdisciplinary method makes it difficult to correctly assess the condition of a river as a complex ecosystem significantly influenced by humans. This study aimed to develop a novel Comprehensive Assessment of Lowland Rivers (CALR) method. It is designed to integrate and evaluate all-natural and anthropopressure-related elements that influence a river. The CALR method was developed using the Analytic Hierarchy Process (AHP). The application of the AHP allowed the assessment factors to be determined and given weights to define the importance of each assessment element. As a result of AHP analyses, the following ranks were determined for the six main parts of the CALR method: hydrodynamic assessment (0.212), hydromorphological assessment (0.194), macrophyte assessment (0.192), water quality assessment (0.171), hydrological assessment (0.152) hydrotechnical structures assessment (0.081). In the comprehensive assessment of lowland rivers, each of the six elements listed above is rated on a scale of 1–5 (where 5 means very good and 1 bad) and multiplied by an appropriate weighting. After summing up the obtained results, a final value is obtained, classifying the river. CALR can be successfully applied to all lowland rivers thanks to its relatively simple methodology. The widespread use of the CALR method may facilitate the assessment process and enable the comparison of the condition of lowland rivers worldwide. The research conducted in this article is one of the first attempts to develop a comprehensive method for evaluating rivers that considers all aspects.

“…The remaining basins, such as the Tordera, Besòs, Fluvià, Muga, Francolí, Foix, Gaià, and Riudecanyes, have a total area below 600 km 2 each, and a scarce and highly irregular flow, with frequent zero flow reaches in dry periods. The Catalan RBD has a high population density (420 inhabitants/km 2 ), which accounts for the strong urban and industrial pressures and high water withdrawals that exacerbate low water flows [39]. According to the Catalan Water Agency (http://aca.gencat.cat (accessed on 9 March 2021)), a total of 248 river water bodies have been recorded (with an average of 17 km per water body and accounting for 6639 km of river network), of which 136 (37%) were identified as heavily modified by morphological and hydrological human alterations, according to the WFD guidelines.…”

The biomonitoring methods implemented by water authorities are mostly developed for perennial rivers, and do not apply to temporary rivers (TRs). We propose a new classification for TRs to better assess their ecological status. It arises from the LIFE+ TRivers project, which was conducted in the Catalan and the Júcar Mediterranean river basin districts (RBD). The European Water Framework Directive (WFD) provided two systems to set river types (systems A or B from Annex II), which have been officially used by water authorities across Europe to set “national river types” (NRTs). However, essential hydrological variables for TRs are largely omitted. NRTs established according to the WFD were compared with TR categories obtained by using a rainfall-runoff model, “natural flows prescribed regimes” (NFPRs), and with “aquatic phases regimes” (APRs) calculated by using TREHS software. The biological quality indices currently used in Spain, based on macroinvertebrates and diatoms (IBMWP, IMMI-T, and IPS), were compared with a “general degradation” gradient in order to analyze the two TR river classification procedures (NFPR and APR). The results showed that NRTs did not properly classify TRs, and that the APR classification identified ecologically meaningful categories, especially those related to stagnant phases. Four “management temporary river categories” based on APRs are proposed to be used for water managers to properly assess the ecological status of TRs.
