“…Nitrogen was the potentially most deficient nutrient for phytoplankton growth during most of the study period according to Redfield ratio. This Mediterranean area suffers from high nitrate levels due to agricultural activity [9]. However, the lake watershed is urban [3] so agriculture is not an important source of nitrate.…”

Urban lakes are artificial systems that accomplish many functions, such as storing rainwater, avoiding flooding of adjacent urban areas and supporting recreational activities. However, their intrinsic aesthetic value is usually reduced due to eutrophication problems and anoxia processes. The objective of this study is to present the results of the water quality monitoring of a small urban lake (11264 m 2 and 1.5 m average depth) in Tavernes de la Valldigna (Valencia, Spain) during summer 2016. The final aim is to determine the better parameters for monitoring urban lakes having into account budget restrictions. La Goleta lake has suffered repeated events of fish deaths and bad odors that cause the alarm of residents and tourists, especially in summer. Municipal authorities undertook a restoration project which first part was developed during the first semester of 2016. Surveillance monitoring should be financed by the Town Council, so limiting the monitored parameters to the most appropriate ones is key for guarantying long-term surveillance. The results of this study show the importance of macrophyte community in determining water quality and maintaining dissolved oxygen levels. Dissolved oxygen is a key parameter easy to measure and a good indicator of lake water quality evolution.Analytical methodologies must be adapted to the high organic matter content of these systems to avoid interferences.

“…The flow is only continuous in the last 1.5 km due to the inputs of freshwater draining La Safor Wetland and it flows into Gandia Harbour [4]. The Vaca River flows directly into the sea in the town of Xeraco; this river often floods the wetland due to storm events characteristic of the Mediterranean climate [16].…”

Abstract:The policies that define the use and management of wetlands in Spain have undergone tremendous changes in recent decades. During the period of 1950-1980, Land Reform Plans promoted filling and draining of these areas for agricultural use. In 1986, with the incorporation of Spain to the European Union (EU), there was a sudden change of direction in these policies, which, thereafter, pursued restoring and protecting these ecosystems. This change, combined with increasing urban development and infrastructure pressures (e.g., roads, golf courses, etc.), creates a conflict of uses which complicates the management of these ecosystems by local governments. This study analyzes the effectiveness of policies and management tools of important coastal wetlands at the local scale in the Valencian Community (Western Mediterranean Sea) using a strengths-weaknesses-opportunities-threats (SWOT) methodology. A supra-municipal model of environmental planning is proposed to enable consistent management at a regional scale. This model enhances local government's effectiveness and it can be applied in other areas with similar problems.

“…The diatom indices are extensively used to assess the ecological status of rivers because of the ubiquitous presence of diatoms in lotic systems [Sebastiá et al 2013] as well as their rapid and varied response to changing bottom-up and topdown control factors [Liu et al 2016, Stevenson et al 2008. Therefore, they can be used for the past, present, and future water quality assessment since they reflect the ecological status comprehensively [Almeida et al 2014].…”

In this study, the authors aimed to compare the performance of the physicochemical-based water quality metrics (WQI, SWQMR) and diatom-based diatom metrics (TDI, BDI, GDI) to evaluate the water quality and ecological status of the Mert Stream. A total of 104 epilithic diatom species, belonging to 44 genera, were recorded during the study period. Navicula was the most dominant diatom in the sites near intensive farming areas, while Gomphonema was the most dominant species in the sites in vicinity of urban and industrial settlements. According to the water quality indices based on the physicochemical parameters and diatoms, the water quality in the upper and middle parts of the Mert stream was better than in the lower parts (higher amount of total suspended solids and higher conductivity). The structure of the epilithic diatom community was mostly shaped by total suspended solids, electrical conductivity and nutrients according to Canonical Correspondence Analysis results. The obtained results revealed that diatom metrics, especially GDI, and water quality metrics, especially WQI, can be used for the monitoring of lotic systems and provide useful complementary information on the ecological status of rivers in medium rainfall regions such as Samsun.
