Abstract:
The ecological assessment of all surface water bodies in Europe according to the Water Framework Directive involves the monitoring of biological, physicochemical and hydromorphological quality elements. For the hydromorphological assessment in particular, there are numerous methods that have been developed and adopted by EU member countries. With this study, we compared three different methods (River Habitat Survey, Morphological Quality Index and River Hydromorphology Assessment Technique) applied in 122 river reaches that are part of the National Monitoring Network of Greece. The main objectives were (a) to identify whether different assessment systems provide similar classifications of hydromorphological status and (b) to distinguish strengths and weaknesses associated with the implementation of each method. Our results show that the River Hydromorphology Assessment Technique (RHAT) and the Morphological Quality Index (MQI) resulted in the same classification for 58% of the studied reaches, while 34% of the remaining cases differed by only one quality class. Correlations between the two indices per river type (ICT) showed that the two indices were strongly correlated for water courses located at low altitudes. Concerning the HMS index of the River Habitat Survey (RHS), which is an index that reflects the overall hydromorphological pressure, it showed larger differences with the other two indices, mainly because it classified more sites as “Poor” and “Bad” quality classes. Based on our results, we recommend that the two indices, RHAT and MQI, can be implemented complementary to the RHS for providing a rather easy and quick assessment of the overall hydromorphological status, at least until a national hydromorphological database is compiled that will allow for the proper adaptation of the Habitat Quality Assessment (HQA) index.

Abstract:
The main goal of this paper is to verify the hypothesis that application of appropriate restoration measures can lead to an improvement in river habitat quality and to achieve good hydromorphological conditions within the ecological status under the Water Framework Directive 2000/60/ES. The study includes an analysis of river network modifications founded on comparing historical and present-day maps, a determination of regional hydromorphological reference conditions based on a field survey and measurements, an assessment of hydromorphological quality of the studied water body and a proposal of appropriate restoration measures. The effects on improvement in hydromorphological status were predicted on the basis of a simulation of hydromorphological conditions after the application of proposed restoration measures. Overall, at least a good hydromorphological status would be achieved. The study proved that it is essential to carry out a hydromorphological survey including a determination of reference conditions as it provides some outputs necessary for a proposal and application of efficient restoration.

Abstract:
The hydromorphological properties of rivers and their floodplains receive increased attention both in basic research and water management. A comparison of hydromorphological parameters before and after river regulation (involving floodplain drainage) provides important information for river management, particularly floodplain rehabilitation. The paper assesses a selected reach of the Drava River and the corresponding floodplain utilising two international approaches, the REFORM framework and the Italian Morphological Quality Index.

Abstract:
Abstract The paper presents the classification of the hydromorphological condition of the Breń River according to the River Habitat Survey (RHS). The research of the hydromorphological assessment of the Breń River, which is a right-bank tributary of the Vistula River and almost entirely flows through the area of the Dąbrowa Tarnowska district was conducted in June 2015. The research sites were situated on the border of the Tarnów Plateau and the Vistula Lowland. The Breń River in these sections flows through rural areas used for agricultural purposes with low-density housing. The analysis of qualitative parameters describing the morphological characteristics were based on two synthetic indices of stream quality: Habitat Quality Assesment (HQA) and Habitat Modification Score (HMS). The calculated numerical values of the two indices proved that the sections of the Breń River correspond with the third and fifth class, which means a moderate (III) and very bad (V) hydromorphological condition.

Abstract:
In this work, hydrochemical and hydromorphological characteristics of urban reservoirs of southwestern Belarus in the spring of 2020 were investigated. Hydromorphological characteristics of reservoirs were determined by field methods and GIS mapping methods. Hydrochemical assessment of water quality of reservoirs in the spring period was carried out according to 15 indicators. Multivariate statistical methods were used to analyze surface water quality. Based on the analysis of hydrochemical and hydromorphological indicators, an assessment of the ecological state of the reservoirs of the urboterritories of southwestern Belarus in the spring period of 2020 was given. During the study, patterns of distribution of morphometric characteristics of the reservoirs within the studied territory were established. The analysis of hydrochemical characteristics showed that the water quality of urban reservoirs depends on the types of anthropogenic effects.

Abstract:
The Water Framework Directive (WFD) requires from member states to monitor hydromorphological features of rivers in order to assess their ecological quality. Thus, numerous hydromorphological assessment methods have been developed with most of them focusing on the dynamics of hydrology, geomorphology and riparian zone extent. Within the scope of this study, we assessed the hydromorphological features of 106 river reaches distributed among thirteen WFD River Basin Districts (RBDs) to identify the main drivers of hydromorphological perturbation at a national scale. The studied reaches reflect a wide range of natural variability as they include various types of watercourses extending from lowlands to mid-altitude and mountainous systems. We employed the River Habitat Survey (RHS), and we recorded hydromorphological features and modifications in both banks and the channel bed along 500 m for each reach. Then, the Habitat Modification Score (HMS) and the individual sub-scores that indicate the extent of specific modifications (e.g., bridges, fords, weirs, bank reprofiling, bank reinforcement, etc.) were calculated in order to a) assess the severity of the total artificial modification and b) to highlight the most common and severe causes of overall alteration. The results showed that alterations such as reprofiling and reinforcement of banks contributed the most to the total HMS followed by the presence of fords and bridges. Particularly, the bank alterations indicate a serious deterioration of the longitudinal profile of the reaches, while the occurrence of many fords and bridges is the main cause for perturbations that affect locally the stream cross-sectional profile. Overall, these results compile a first nationwide assessment of the hydromorphological status of Greek rivers in line with the WFD and set the basis for further research that will focus on the diversity of stream habitat features as a measure for the overall ecological quality.

Abstract:
Abstract Rivers are hydromorphologically assessed in line with the Water Framework Directive. In order to assess the quality of the Parsęta River environment, the River Habitat Survey method was applied. The research studies, conducted in June 2016, provided an overview of hydromorphological issues, and also covered measurements and laboratory analyses on the quality of its waters. There were 24 measuring sections selected along the whole river. The selection of these sections took into account the representativeness of genetically various types of river valley, its size and discharge, and the variability of anthropogenic pressure. The assessment showed that the Parsęta River varies in natural quality (its HQA index ranged from 17 to 61) and that the modification of its valley is variable but generally low (its HMS index ranged from 0 to 33). Seventy-nine percent of the analysed sections were classified to the second (II) and third (III) hydromorphological classes, 8% to the first (I), and 13% to the fourth (IV). The central section of the Parsęta River has the highest degree of naturalness and the lowest degree of transformation. The river valley sections of kettle-hole origin are more transformed than those of fluvial origin. The quality of the Parsęta River waters assessed on the grounds of their physicochemical parameters indicates that the river is in good condition. The individual river water parameters are most often within the first (I) and second (II) classes. Any instances of the quality of waters being below the “good” level are due to phosphate concentrations exceeding the second (II) class and are contained within a 15-km stretch of the river below Białogard. A river section with a high degree of hydromorphological naturalness has the worst quality of waters.

Abstract:
The study deals with an integral assessment of hydromorphological and geoecological conditions of the Hukiv (flatland type of river), Dereluy (foothill type of river), and Vyzhenka (mountainous type of river) river basin systems (Figure 1). The indicators characterizing the river basin in the best way as a holistic system, the channel, floodplain, and watershed altogether, in natural reference conditions and in terms of human economic activity are addressed. The assessment hydromorphological test and geoecological monitoring of small rivers (SWOT-analysis) in accordance with the developed universal algorithm for hydromorphological assessment of small river basins for the sustainable development goals are generated and fulfilled. Interpretation maps for the sustainable development of the Hukiv, Dereluy and Vyzhenka rivers are created. The practical importance and relevance concerns the potential application of the proposed monitoring and the algorithm to solve methodological and applied problems related to the functioning of the systems “basin–river–human” and “basin–river–riverbed” in terms of modern human activity and needs; the need to modify consumer-type stereotypes for the use of natural resources, as well as to provide recommendations for enhancing the resource-efficient and sustainable activities in basin systems and small rivers.

Abstract:
Assessment of river rehabilitation and restoration projects, as well as the monitoring of morphological changes in rivers requires collection of hydromorphological parameter data (i.e. depth, velocity and substrate). Field data collection is highly time and cost consuming and thus, effective and efficient monitoring programmes need to be designed. Interpolation techniques are often used to predict values of the variables under study at non measured locations. In this way, it is not necessary to collect detailed data sets of information. The accuracy of these predictions depends upon (i)the method used for the interpolation and/or extrapolation procedure and (ii) the sampling strategy applied for the collection of data. Even though the design of effective sampling strategies are of crucial importance when applying interpolation techniques, little work has been developed to determine the most effective way to collect hydromorphological data for this purpose. This project aimed to define a set of guidelines for effective and efficient hydromorphological data collection in rivers and relate this to the type of river site that is being sampled and to the objective for which the data are being collected. The project is structured in three main sections: spatial problem, the scaling problem and the temporal problem. Spatial problem refers to the location and number of points that need to be collected. Scaling problems focus on the study of the river length that needs to be sampled to characterise the spatial variability of a river site, whilst temporal problems determine how often a river site needs to be sampled to characterise the temporal variability associated with changes in discharge. Intensive depth data sets have been collected at a total of 20 river sites. These data sets have been used to investigate the spatial, temporal and scaling problems through geostatistical theory.

Abstract:
This study explores the role and skills of hydromorphological assessment methods in supporting river management and restoration, with a major focus on the Italian process-based method MQI (Morphological Quality Index; Rinaldi et al., 2011), and its applicability to European rivers, in order to fulfil the requirements of the Water Framework Directive (WFD; European Commission, 2000). Three major objectives directed the lines of analysis: i) to critically review the European methods and their capacity in supporting WFD river management stages; ii) to analyse the diagnostic capacity, robustness and objectivity of MQI and verify its potential to inform river management and restoration; iii) to test and enable the applicability of MQI to European rivers through appropriate modifications and finally propose an enhanced version to support management and restoration of Italian and European rivers compliantly with WFD.

Abstract:
AbstractSediment connectivity is a distributed property of river systems that emerges from the connected transfer of sediment between multiple sources and sinks. Its disruption, brought by anthropic disturbances, can have severe and unforeseen consequences on both fluvial ecosystems and human livelihood. Modeling network-scale sediment connectivity provides a foundational understanding of river processes and their response to new pressures and can be used to forecast future system evolutions. In this chapter, we present the basin-scale, dynamic sediment connectivity model D-CASCADE (Dynamic CAtchment Sediment Connectivity And DElivery), which quantifies spatiotemporal patterns of sediment delivery in river networks. D-CASCADE considers multiple factors affecting transport, including heterogeneities in hydrology and sediment supply, different grain sizes, channel morphological evolution, and reservoir presence and management. The model is designed to be flexible, data parsimonious, and computationally efficient. We also present two applications of D-CASCADE in real-world case studies for historic geomorphic evolution reconstruction and future dam impacts forecasting. D-CASCADE is intended for integrated, basin-scale water management efforts, to perform multiple screening of various decision portfolios for hydromorphological impact assessments.

Abstract:
The objective of this work was to present several benchmarks regarding the water quality at hydrological basin level under increasing anthropogenic pressures. The first part briefly describes the sources of water pollution, the hydromorphological pressures, and the main water quality parameters widely used for the assessment. The second part presents as an example the dynamics of several water quality parameters recorded between 2007 and 2014 downstream of Argeș River, Romania, near the confluence with the Danube River. Argeș River supplies water for several important Romanian cities including Bucharest, and from here comes the rationale of the work, which envisages characterizing water quality status to substantiate proper water management. The following parameters were statistically analyzed: water temperature, suspended solids, pH, dissolved oxygen, biochemical oxygen demand, ammonium, nitrates, nitrites, and dissolved heavy metals. The factor analysis results showed that the first factor contains temperature and dissolved oxygen, the second has the heavy metals, the third groups have the ammonium and pH, the fourth contains the TSS and nitrites, while the fifth is formed by BOD5 and nitrates. Water quality plays a significant role in promoting socioeconomic development and maintaining viable ecosystems. The protection of water quality requires improved monitoring and reliable watershed management plans.
