“…The results confirm that this type of sediment treatment produces a material applicable as a substitute to the sand in road buildings. Another study dealing with the environmental impact of channel sediment was described in [19]. The adverse influence on the water quality and life conditions for channel biota can be affected based on the detected concentrations of macronutrients exceeding their content in the surrounding arable land by a few folds owing to the interactive processes between the water and sediment material.…”

“…The adverse influence on the water quality and life conditions for channel biota can be affected based on the detected concentrations of macronutrients exceeding their content in the surrounding arable land by a few folds owing to the interactive processes between the water and sediment material. Clearly, environmental issues dealing with dredged sediment utilization in road construction is a highly relevant topic [2,[18][19][20][21][22][23][24][25][26] and needs to be addressed when analyzing the potential use of any kind of new material, particularly one usually classified as waste.…”

Special-purpose river port sediment was investigated for its potential use as a road construction material. Sediment samples were extracted from three locations in three small river ports, and detailed laboratory research was conducted to determine its basic mechanical properties and characteristics that can potentially have an adverse influence in a roadside environment. The results of the research conducted indicate that there is a need for systematic monitoring of the quality and quantity of sediment in special-purpose river ports of the Danube River Basin to maintain its mobility and prevent flooding. The basic engineering characteristics (Proctor elements, Atterberg limits, California bearing ratio, and unconfined compressive strength) determined represent the good potential of the sediment samples tested herein for use in road construction. In addition, the chemical characteristics tested indicate the need for detailed analyses of the potential environmental risk before application in civil engineering structures

“…In addition, other aspects, and issues of eutrophication, such as socioeconomic [36], hydrotechnical (e.g., reduced water flow and water course capacity, increased risk of flooding, impaired operational and hydrotechnical facilities, increased management costs, reduced aesthetic values of waterbodies) issues [22,[37][38][39] are also very prominent.…”

“…Issues regarding nutrients and eutrophication in natural or artificial lakes, and other water courses (e.g., rivers, drainage canal networks), are present in Serbia and surrounding regions with similar agroecological conditions, especially in predominantly agricultural lowlands such as Vojvodina [25,37,38,[58][59][60][61][62][63][64]. Such waterbodies face additional challenges, as they consist of finely structured sediments loaded with high concentrations of nutrients that interact between their solid and liquid matrices [1,22,33,[65][66][67].…”

“…Its main canal network (about 960 km long) consists of artificial and integrated smaller natural water courses. This channel network is incorporated into the farmlands, breaking the monotony of the "cultivated steppe", ensuring a specific ambience and scenic values [37,38,63]. For most of the year, the channels are calm and shallow, with low flows; however, exposure to the effects of non-point source pollution from surrounding agricultural lands, as well as municipal and industrial sources, leads to dominantly untreated wastewaters stemming from these networks.…”

Conserving clean and safe freshwater is a global challenge, with nitrogen (N) and phosphorus (P) as frequent limiting factors affecting water quality due to eutrophication. This paper provides a critical overview of the spatiotemporal variability in both nutrient concentrations and their total mass ratio (TN:TP) in the canal network of the Hydro system Danube–Tisza–Danube at 21 measuring locations monitored by the Environmental Protection Agency of the Republic of Serbia over a length of almost 1000 km, collected once a month during the last decade. A spatiotemporal variation in nutrient concentrations in the tested surface water samples was confirmed by correlations and cluster analyses. The highest TN concentrations were found in winter and early spring (non-vegetation season), and the highest TP concentrations in the middle of the year (vegetation season). The TN:TP mass ratio as an indicator of the eutrophication pointed out N and P co-limitation (TN:TP 8–24) in 64% of samples, N limitation (TN:TP < 8) was detected in 27% and P limitation (TN:TP > 24) in the remaining 9% of water samples. Such observations indicate slow-flowing, lowland water courses exposed to the effects of non-point and point contamination sources as nutrient runoff from the surrounding farmlands and/or urban and industrial zones, but further investigation is needed for clarification. These results are an important starting point for reducing N and P runoff loads and controlling source pollution to improve water quality and underpin recovery from eutrophication in the studied watershed.

Waters are among to the most vulnerable environmental resources exposed to the impact of various point and non-point pollutants from rural/urban activities. Systematic and long-term monitoring of hydro-resources is therefore of crucial importance for sustainable water management, although such practice is lacking across many (agro-)hydro-ecosystems. In the presented study, for the first time, the spatial distribution (covering almost 9000 ha) and temporal variation (2006-2013) in certain quality parameters was characterized in drainage watercourses Tatarnica and Subic, whose catchment is rural and suburban areas close to the city of Novi Sad, Republic of Serbia. Based on majority of observed parameters, both watercourses belonged to I and II water quality classes, with occasional presence of certain parameters (e.g., suspended solids, total phosphorus; ammonium) at extreme values exacerbating both watercourses to classes IV and V. The value of the synthetic pollution index (i.e., a combined effect of all considered parameters) showed a higher degree of water pollution in watercourse Subic (on average 2.00) than Tatarnica (on average 0.72). Also, cluster analysis for watercourse Tatarnica detected two groups of parameters (mostly related to nutrients and organic matter), indicating more complex impacts on water quality during the observed period, in which elucidation thus established water quality monitoring program would be of great importance.
