Although the CFWs have not been largely utilized in the water reservoirs in the agricultural landscape yet, a positive impact on quality of water running off the basin with the intensive agricultural activities can be assumed based on the evidenced efficiency.…”

In the Czech Republic, a significant amount of agricultural landscape nutrients is swept away by surface washes and leakages to subsoil. Subsequently there is a negative influence on surface water quality, where of course also point sources of pollution participate in. Flowing surface water often becomes stagnant while the certain self-purifying processes proceed both in the flowing and stagnant waters. It can be simultaneously stated that the self-purifying process is practically uncontrollable, primarily due to the impact of many entering factors. One of the environmental and technical elements providing quality improvement of water running off a water reservoir is deployment of constructed floating wetlands (CFW). The theoretical background, as well as the laboratory measurements carried out on the test land of the Brno University of Technology in experimental tanks, evidence the significant treatment efficiency of the CFW. Within the research activities, we focused on the general pollution parameters set for surface waters. The first results show that the total phosphorus concentration removal efficiency is 38.8 % after 22 days with employment of the CFW which is a considerably higher value compared to the lysimeter with no CFW where the removal efficiency was only 4.37 %. The results can be large-scale applied to most of the small water reservoirs situated in the agricultural landscape.

“…Since the 1980s, planted floating island has been widely researched and applied in USA (3,4), Netherlands (5), Japan (6), China (7, 8). Numerous scientists (9,10) summarized the design, operation, plant, and management of planted island treatment, especially the data meta-analysis of various applications. Remarkably, Eichhornia crassipes have been widely applied in a floating island for the treatment of surface water and wastewater, for the ability to adapt equally well at several location and climate zone (11, 12, 13, 14).…”

13A multilayer solar planted floating island (MS-PFI) planted with Eichhornia 14 crassipes are potential alternatives to traditional PFI. The highest removal rates of 15 suspended solids, total nitrogen, total phosphorus, ammonia nitrogen and chemical 16 oxygen demand was 86%, 75%, 80%, 95% and 84%, respectively. Proteobacteria 17 (average 43.4% of total sequences) and Actinobacteria (19.9%) were the dominant 18 phyla. Numerous genus had obvious differences between influent and effluent water, for 19 instance, 13, 12 and 7 % in effluent water were assigned to the hgcl_clade, 20Norank_c_Cyanobacteria, and Rhizorhapis, while their relative abundances were 21 decreased to 5, 3 and 0 %. In contrast, a distinct increase among Flavobacterium (10%), 22Limnohabitans (7%), Alpinimonas (4%), norank_p_Saccharibacteria (4%), Erwinia (3%) 23 after MS-PFI treatment. MS-PFI brings various bacteria involved in contaminant 24 degradation and nutrient removal in biological wastewater treatment systems. An 25 amount of ¥ 1,843 was totally inputted to construct floating bed, which was rarely 26 needed operation and maintenance costs. 27Importance 28In-situ micro-polluted water ecological remediation, microorganisms and plants are 29 effective to improve environmental quality and provide essential ecosystem services. 30Recently, we invent a new multilayer solar with an excellent pollutant removal 31 efficiency.

“…Riparian reforestation and the increase of the quality and quantity of tree-related habitats are measures related to habitat conservation and pollution abatement during flood events. The application of floating islands may be a technically and economically efficient method to decrease pollution, particularly during low flow periods (Pavlineri et al, 2017).…”

Non-perennial rivers and streams (NPRS) cover N 50% of the global river network. They are particularly predominant in Mediterranean Europe as a result of dry climate conditions, climate change and land use development. Historically, both scientists and policy makers underestimated the importance of NRPS for nature and humans alike, mainly because they have been considered as systems of low ecological and economic value. During the past decades, diminishing water resources have increased the spatial and temporal extent of artificial NPRS as well as their exposure to multiple stressors, which threatening their ecological integrity, biodiversity and ecosystem services. In this paper, we provide a comprehensive overview of the structural and functional characteristics of NPRS in the European Mediterranean, and discuss gaps and problems in their management, concerning their typology, ecological assessment, legislative and policy protection, and incorporation in River Basin Management Contents lists available at ScienceDirect Science of the Total Environment j o u r n a l h o m e p a g e : w w w . e l s e v i e r . c o m / l o c a t e / s c i t o t e n vPlans. Because NPRS comprise highly unstable ecosystems, with strong and often unpredictable temporal and spatial variability -at least as far as it is possible to assess -we outline the future research needs required to better understand, manage and conserve them as highly valuable and sensitive ecosystems. Efficient collaborative activities among multidisciplinary research groups aiming to create innovative knowledge, water managers and policy makers are urgently needed in order to establish an appropriate methodological and legislative background. The incorporation of NPRS in EU-Med River Basin Management Plans in combination with the application of ecological flows is a first step towards enhancing NPRS management and conservation in order to effectively safeguard these highly valuable albeit threatened ecosystems.
