“…Generally, the share of this fraction flowing to zone D will be increased by even 30% (December) when compared to the baseline scenario, but only an average of 10% of them will settle there. Since this zone is used as a source of drinking water, the extended presence in this part of the reservoir should be further investigated due to their role as a contaminant carrier, as previously discussed (Szalińska et al 2021).…”

“…To achieve the goal of the study, i.e., to track sediment particles from their source to the deposition area, the DNS (Discharge Nutrient Sea) digital platform (Macromodel DNS) has been used as a modeling tool. The Macromodel DNS, developed at the Institute of Meteorology and Water Management-National Research Institute (Instytut Meteorologii i Gospodarki Wodnej-Państwowy Instytut Badawczy, IMGW-PIB) (Wilk et al 2018b;Wilk and Orlińska-Woźniak 2019), provides an interactive platform allowing for integration of the SWAT (Soil and Water Assessment Tool) module (version 2012) (Arnold et al 2012;Abbaspour et al 2015) with other modeling tools (modules) to track different processes of the sediment/contaminant transport in a catchment (Wilk et al 2018a;Szalińska et al 2020Szalińska et al , 2021Orlińska-Woźniak et al 2020a). The RR catchment module has been created in the SWAT module (Fig.…”

“…average for 2026-2035), and long-term (H2, average for 2046-2055) time horizons. The scenarios employed to estimate sediment load discharged into the DR were adopted from the Polish Development of Urban Adaptation Plans (UAP) (MPA 2021a, b), which have been described in detail in previous studies (Orlińska-Woźniak et al 2020b;Szalińska et al 2021). Since they have been prepared with a monthly time step, the impact of meteorological parameter changes could be tracked in detail, which was not possible when seasonal forecasts were given previously (Orlińska-Woźniak et al 2020a).…”

Purpose The study tracks spatial and temporal distribution of sediment particles from their source to the deposition area in a dammed reservoir. This is particularly important due to the predicted future climate changes, which will increase the severity of problems with sediment transport, especially in catchments prone to erosion. Methods Analyses were performed with a monthly step for two mineral and one mineral/organic sediment fractions delivered from the Carpathian Mts. catchment (Raba River) to the drinking water reservoir (Dobczyce) by combining SWAT (Soil and Water Assessment Tool), and AdH/PTM (Adaptive Hydraulics Model/Particle Tracking Model) modules on the digital platform—Macromodel DNS (Discharge Nutrient Sea). To take into account future changes in this catchment, a variant scenario analysis including RCP (representative concentration pathways) 4.5 and 8.5, and land use change forecasts, was performed. Results The differences between the two analyzed hydrological units (catchment and reservoir) have been highlighted and showed a large variability of the sediment load between months. The predicted climate changes will cause a significant increase of mineral fraction loads (silt and clay) during months with high flows. Due to the location and natural arrangement of the reservoir, silt particles will mainly affect faster loss of the first two reservoir zones capacities. Conclusions The increased mobility of finer particles (clay) in the reservoir may be more problematic in the future, mainly due to their binding pollutant properties, and the possible negative impact on drinking water abstraction from the last reservoir zone. Moreover, the study shows that the monthly approach to forecasting the impact of climate change on sediment loads in the reservoir is recommended, instead of a seasonal one.

Currently, climate change is considered as an important factor affecting nutrient loads introduced through riverine systems into the Baltic Sea. Although the prospect of a large increase in pollution has long seemed very real, it still does not translate into planning of effective remedial actions. One of the factors limiting the development of such activities is the scale of simulations, focusing generally on catchment outlet profiles. To fill this gap and enable a step forward in understanding responses towards future predictions in a higher resolution scale (subcatchment), we assessed nutrient load contribution using calculation profiles localised along a main watercourse and its tributaries. To track spatial and seasonal changes of total nitrogen and phosphorus under short- and long-term (RCP4.5 and RCP8.5) climate change scenarios we used the digital platform Macromodel DNS/SWAT. Having at our disposal a catchment model with a good performance we could follow not only total load changes in particular subcatchments, but also track localisation of the pollution sources and their direct impact on load estimations. Our results showed an increase of the loads, especially from the agricultural landuse type, up to 34% for TN and 85% for TP in the most extreme scenario. Moreover, forest areas have been noted as highly reactive to the climate changes, and through their localisation able to distinctly alter nutrient outflow. Finally, the contribution of urban areas should be further investigated since the dynamics of nitrogen and phosphorus release from impervious surfaces is noticeably different here than from the other diffuse sources.

“…The second cause of solid contamination is related to environmental pollution of human origin. Global warming causes the decrease of vegetation on the slopes of rivers, accelerating the precipitation of solids in these (Goode, Luce, & Buffington, 2012;Szali nska et al, 2021). Similarly, human-made deforestation is one of the leading causes of the increase in TSS levels (Cotel, Viville, Benarioumlil, Ackerer, & Pierret, 2020).…”

The watersheds of the Quindío River in Colombia South America have high levels of contamination by total suspended solids (TSS). The objective of this work was to represent the entire hydrographic network of the watersheds of the Quindío department by means of a graph and, using network theory, analyze the different centrality measures to identify areas most prone to TSS contamination. Similarly, partial differential equations were used to simulate the transport of TSS pollutants between specific points of the basin. For this purpose, a network of 409 nodes and 408 edges was created based on topographic maps and reports from the corporations in charge of preserving these watersheds. With information on contamination zones, the network, and partial differential equations, TSS transport was calculated throughout the hydrological network, identifying eight critical zones with high levels of this parameter. Some of these zones are on major rivers, such as the Quindío River near the city of Armenia; the Roble, Espejo, and San Juan rivers also have considerable levels.
