While stream restorations are increasingly being adopted to mitigate sediment and nutrient inputs and to meet water quality regulatory targets, less information is available on the drivers behind the design, implementation, effectiveness, and cost of restorations. We address these issues for a $4.2 million stream restoration for legacy sediments implemented for a rural Piedmont stream in Maryland, USA. A total of 1668 m of stream was restored in three phases, which included the partial removal of legacy sediments, the grading of streambanks, floodplain creation, channel reshaping with meanders and pool-riffle forms, the raising of the stream bed, and the planting of riparian vegetation. The sediment, nitrogen, and phosphorus concentrations and fluxes were monitored before- and during the restoration phases. The sites selected for restoration had legacy sediments vulnerable to erosion and were on state-owned land. The restoration design was based on the need to maintain mature riparian trees and preserve existing sensitive wetland habitats. Water quality monitoring indicated that the sediment and nutrient fluxes increased during the restoration phase and were attributed to disturbance associated with construction activities and increased runoff. We also recommend that soil health needs to be included as an integral component to enhance the effectiveness and resilience of stream restorations.

<p>The interplay between riparian vegetation and water flow in vegetated water bodies has a key role in the dynamic evolution of aquatic and terrestrial ecosystems in wetlands and lowlands. The present study analyzes the effects of the spatial distribution of reed (<em>Phragmites australis</em> (Cav.) Trin. ex Steud.) beds, an invasive riparian species extremely widespread in wetland and lowlands worldwide, on the main hydraulic and hydrodynamic properties of an abandoned vegetated reclamation channel located in Northern Tuscany, Italy. A field campaign was carried out to obtain Leaf Area Index (LAI) and Normalized Difference Vegetation Index (NDVI) of reed beds through both ground-based and Unmanned Aerial Vehicle (UAV) methodologies, and to correlate them to the channel’s flow dynamic and water quality main features. Then, Hydrodynamic simulations of the vegetated reclamation channel were performed and validated based on the experimental measurements of the hydraulic and vegetational parameters acquired in the field to build up a robust model to be employed also in future Ecohydraulic researches. The evidences of this study constitute useful insights in the quantitative analysis of the correlation between the spatial distribution of riparian vegetation stands in natural and manmade vegetated water bodies and their hydrodynamic and water quality main features.</p>

This work developed and tested a rapid assessment protocol (RAP) in a watershed of the Paraíba do Sul River Basin, to be applied by elementary school students. The study was conducted in a public school of São José dos Campos (SP), with 60 students of the 6th grade (n = 30) and 7th grade (n = 30). The protocol developed includes 12 parameters with text consistent with student levels and with illustrations of the variables of each parameter. The parameters are the type of usage of the stream margins, erosion and siltation, presence of sewage, presence of aquatic plants, water odor, water oiliness, water transparency, type of bottom, rapids and water flow, garbage presence, the presence of animals, and the presence of riparian vegetation. The results showed that 65% of the students understood all parameters and showed great interest in the proposed protocol; the others needed to better understand the parameters of erosion and siltation, presence of aquatic plants, rapids, water flow and presence of riparian vegetation. It was found that the developed RAP was appropriate and can contribute as an educational tool for the study of water quality.

Rivers play a major role for communities especially in fisheries and as a source of water for people residing within the vicinity. Water quality is of utmost importance and it covers a wide range of approaches and conflicts. Water is super abundant on the planet, as whole, but fresh potable water is not always available at the right time or the right place for human or ecosystem use [3]. Water quality refers to the physical, chemical and biological characteristics of water. It is a measure of the condition of water relative to the requirements of one or more biotic species and or to any human need or purpose. It is most frequently used by reference to a set of standards against which compliance can be assessed. Sembrong dam reservoir was built by damming a river. When a reservoir is built along a river’s flow, the physical, chemical and biological conditions of the river are disrupted to some degree [2]. Since Sembrong dam reservoir is constructed on large lowland rivers with gradually sloping banks, it can be characterized by inundation of large areas, extreme horizontal variability with extensive shallows riparian vegetation and shallow reservoir. Such reservoir is usually eutrophic and high natural organic load are likely to contribute to the formation of an anoxic hypolimnion [9]. Shallow reservoir is usually well mixed by wind, and this leads to non-stratified condition [7]. Therefore, Sembrong dam reservoir can be categorized as shallow unstratified reservoir.

Resumen: La degradación de la calidad del agua y de la vegetación de ribera en los ríos mediterráneos es hoy en día un importante problema ambiental.  El río Mijares discurre por la provincia de Teruel desde su nacimiento en la Sierra de Gúdar -municipio de El Castellar-, a 1.500 metros de altura y forma impresionantes cañones y paisajes fluviales en este tramo alto de un gran valor ambiental. Sin embargo, en este trabajo se analiza de manera cualitativa la calidad de sus aguas y de la vegetación de ribera para mostrar que este gran recurso territorial para el desarrollo rural de la zona presenta unos niveles de contaminación preocupantes. Posteriormente se argumenta a la luz de los datos obtenidos, que las áreas en despoblación y con muy escasa presencia humana también presentan problemas ambientales que están relacionados con una presencia institucional muy débil en este tipo de territorios.   Palabras clave: cursos fluviales, problemas ambientales, despoblación, Teruel.   Abstract: The degradation of water quality and riparian vegetation in Mediterranean rivers is today a major environmental problem. The upper basin of the Mijares river flows through the province of Teruel from its source in the municipality of El Castellar at 1,500 meters high and forms some impressive canyons and river landscapes in this upper section of great environmental value. However, this research qualitatively analyzes the quality of its waters and the riverside vegetation to show that this great territorial resource for rural development in the area presents important levels of degradation. Subsequently, it is discussed in the light of the data obtained, that the areas in depopulation and with very little human presence also present environmental problems that are related to a very weak institutional presence in this type of territories.   Key words: rivers, environmental problems, depopulation, Teruel
