Opis:
When high precision modelling is required, for example, with the estimation of suspended sediment load (SSL), data-driven models are preferred over physically-based numerical models for their real-time, short-horizon prediction ability. The investigation of SSL, as an important index in engineering practices assessment, like design and operation of the hydraulic structures not only shows the hydrological behaviour of the river, but also illustrates the valuable information about the water quality deterioration, surface-groundwater interaction and land-use changes of the watershed. The following data-driven methods were compared in order to predict SSL at the Seyra gauging station on the Karaj River in Iran: Fuzzy logic (FL), two adaptive neuro-fuzzy inference systems (i.e., ANFIS-GP and ANFIS-FCM models), an artificial neural network (ANN), and least squares support vector machine (LSSVM). Monthly average river flow and SSL data for 50 years were obtained from the Tehran Regional Water Authority (TRWA). The data was first divided into training, validation and test sets and the SSL was then predicted using the ANN, FL, ANFIS, and LSSVM models. The reliability of the applied models was evaluated by the correlation coefficient (R), root mean square error (RMSE), and mean absolute error (MAE). The results showed that the ANFIS models outperformed the ANN, FL, and LSSVM models for predicting SSL using the given input and output data. Overall, the performances of the artificial intelligence models used in the present study were satisfactory in predicting the non-linear behaviour of the SSL.

Opis:
Fluctuations in suspended sediment concentration (SSC) has been investigated in the Warta River(western Poland), based on data obtained for the period 1961-1980 from three gauge stations located in upstream, middle-stream and downstream areas. Over the two decades, the SSC values demonstrated wide fluctuations and an overall increase at each gauge station. No significant correlation was generally observed between SSC and discharge but high SSC was found to follow low discharge and increasing temperature during the summer seasons in some years. Measurements of SSC and discharge were used to estimate total annual suspended sediment load (SSL). SSL values were found to increase downstream along with an increase in discharge. SSC decreases along the river course. However, when it comes to changes over time, SSL variability was mainly determined by SSC changes. The maximum SSC values were primary caused by anthropogenic factors: the disposal of mine wastewater upstream, river training works, increased urbanisation and the intensification of sewage disposal. Where the river catchment has been greatly affected by anthropogenic factors, a denudation index calculated solely based on SSC and discharge does not appear to reflect the actual denudation rate, and must be treated with caution.

Opis:
Estimating the amount of suspended sediment in rivers correctly is important due to the adverse impacts encountered during the design and maintenance of hydraulic structures such as dams, regulators, water channels and bridges. The sediment concentration and discharge currents have usually complex relationship, especially on long term scales, which can lead to high uncertainties in load estimates for certain components. In this paper, with several data-driven methods, including two types of perceptron support vector machines with radial basis function kernel (SVM-RBF), and poly kernel learning algorithms (SVM-PK), Library SVM (LibSVM), adaptive neuro-fuzzy (NF) and statistical approaches such as sediment rating curves (SRC), multi linear regression (MLR) are used for forecasting daily suspended sediment concentration from daily temperature of water and streamflow in the river. Daily data are measured at Augusta station by the US Geological Survey. 15 different input combinations (1 to 15) were used for SVM-PK, SVM-RBF, LibSVM, NF and MLR model studies. All approaches are compared to each other according to three statistical criteria; mean absolute errors (MAE), root mean square errors (RMSE) and correlation coefficient (R). Of the applied linear and nonlinear methods, LibSVM and NF have good results, but LibSVM generates a slightly better fit under whole daily sediment values.

Opis:
The carried out measurement of waters flow and suspended sediment concentration in the river Wisłoka and the small water reservoir at Krempna constituted the basis of determination of conditions of suspended load transport at low water flow according to van Rijn’s criteria (1984). The results of measurements carried out in the river and in the reservoir permitted elaboration of profi les of suspended sediment concentration Ca on the reference level “a”. The reference level was established according to van Rijn’s methods. In the river the reference level was adopted as 0.5 of the diameter of the biggest particle, and in the water reservoir 0.01 of elevation in a given hydrometric vertical. Measurement were performed at a flow equalling 0.89 m3⋅s–1. Concentration Ca in the river in fi ve hydrometric verticals, determined from the concentration profile, ranged from 11.4 to 25.3 g⋅m–3. The concentration value, calculated according to van Rijn’s formula was within the range 11.2–36.5 g⋅m–3 and the average it was over 26% higher than that determined from the concentration profile. In the water reservoir concentration measurements were performed in appointed verticals in eight cross-sections. At a flow 0.89 m3⋅s–1 in the water reservoir critical bed shear velocities causing movement of bottom material will not be exceeded. The calculated stage transport parameter (T) equaled from –0.9961 to –0.9996 in particular verticals of cross-sections. With regard to the negative values of the stage transport parameter (T) it proved impossible to calculate concentration Ca in the reservoir by use of the van Rijn’s formula.
Określenie ilości rumowiska unoszonego transportowanego w rzekach jest istotne ze względu na zamulanie zbiorników wodnych. Opisanie warunków transportu rumowiska unoszonego na podstawie badań empirycznych wiąże się z koniecznością wprowadzenia parametrów hydraulicznych opisujących przepływ wody i parametrów charakteryzujących rumowisko unoszone. Badania warunków transportu rumowiska unoszonego przeprowadzono w rzece Wisłoce i w zbiorniku wodnym w Krempnej na podstawie teorii podanej przez van Rijna [1984]. Zaproponowane przez van Rijna empiryczne równanie służące obliczeniu tej koncentracji uwzględnia podstawowe parametry, takie jak: parametr ziarnowy (D*) i parametr transportu (T). Ocena możliwości zastosowania tej metody wiąże się z określeniem warunków transportu rumowiska unoszonego. Na podstawie przeprowadzonych badań w rzece i małym zbiorniku wodnym, obejmujących pomiary przepływu wody i koncentracji rumowiska unoszonego, określono warunki transportu rumowiska przy przepływie niskim według kryteriów podanych przez van Rijna [1984], a także na podstawie opracowanych profi li koncentracji obliczono koncentrację na poziomie odniesienia „a”. Wykonane pomiary przepływu wody i koncentracji rumowiska unoszonego w rzece Wisłoce i małym zbiorniku wodnym w Krempnej stanowiły podstawę określenia warunków transportu rumowiska przy przepływie niskim, według kryteriów podanych przez van Rijna [1984]. Wyniki pomiarów w rzece i w zbiorniku umożliwiły opracowanie profi li koncentracji i określenie koncentracji rumowiska unoszonego Ca na poziomie odniesienia „a”. Poziom odniesienia ustalono według metodyki van Rijna. W rzece przyjęto poziom odniesienia równy 0,5 średnicy największego ziarna, a w zbiorniku równy 0,01 napełnienia w danym pionie hydrometrycznym. Pomiary wykonano przy przepływie wynoszącym 0,89 m3⋅s–1. Koncentracja Ca w pięciu pionach hydrometrycznych, określona z profi li koncentracji, wynosiła od 11,4 do 25,3 g⋅m–3. Obliczona wzorem van Rijna wartość koncentracji Ca mieściła się w przedziale 11,2–36,5 g⋅m–3 i była średnio ponad 26% wyższa od określonej z profi li koncentracji. W zbiorniku wodnym przy przepływie 0,89 m3⋅s–1 nie zostaną przekroczone krytyczne prędkości ścinające, powodujące ruch materiału dennego. Obliczony parametr transportu (T) w poszczególnych pionach przekroi poprzecznych wynosił od –0,9961 do –0,9996. Ze względu na ujemne wartości parametru transportu (T) niemożliwe okazało się obliczenie koncentracji Ca w zbiorniku. Została ona ustalona z profi li koncentracji. Przy przepływie średnim niskim w rzece Wisłoce koncentracja Ca rumowiska unoszonego, określona według metodyki van Rijna jest średnio ponad 26% wyższa od określonej z profi li koncentracji. Koncentracja na poziomie odniesienia „a” określona z profili koncentracji opracowanych według danych z pięciu pionów hydrometrycznych wynosiła od 11,4 do 25,3 g⋅m–3. Najwyższe koncentracje odnotowano w głównym nurcie rzeki. Określenie koncentracji Ca w zbiorniku wodnym przy przepływie 0,89 m3⋅s–1 według wzoru van Rijna nie jest możliwe, gdyż ze względu na panujące warunki hydrodynamiczne nie zostają przekroczone krytyczne prędkości ścinające (u*cr), powodujące ruch mineralnego materiału dennego.

Opis:
Assessing the tendency of suspended sediment concentration (SSC) in the river watersheds enables a better understanding of the hydromorphological properties of its basins and the associated processes. In addition, analyzing this trend is essential to address several important issues such as erosion, water pollution, human health risks, etc. Therefore, it is critical to determine a proper method to quantify spatio-temporal variability in SSC. In recent years, remote sensing and GIS technologies are being widely applied to support scientists, researchers, and environmental resource investigators to quickly and synchronously capture information on a large scale. The combination of remote sensing and GIS data will become the reliable and timely updated data source for the managers, researchers on many fields. There are several tools, software, algorithms being used in extracting information from satellites and support for the analysis, image interpretation, data collection. The information from satellite images related to water resources includes vegetational cover, flooding events on a large scale, rain forecast, population distribution, forest fire, landslide movements, sedimentation, etc., and especially information on water quality, sediment concentration. This paper presents the initial result from LANDSAT satellite image interpretation to investigate the amount of sediment carried downstream of the Ba river basin.

The port of Khour Al-Zubair is located 60.0 km south of the city centre of Basrah; it is also located 105.0 kilometres from the northern tip of the Arabian Gulf. The main goal of this paper is to estimate the concentration of suspended deposit (SSC) in “Khour Al-Zubair” port using a Multilayer Perceptron Neural Network (MLP) based on hydraulic and local boundary parameters while also studying the effect of these parameters on estimating the SSC. Five input parameters (channel width, water depth, discharge, cross-section area, and flow velocity) are used for estimating SSC. Different input hydraulic and local boundary parameter combinations in the three sections (port center, port south, and port north) were used for creating nine models. The use of both hydraulic and local boundary parameters for SSC estimation is very important in the port area for estimating sediment loads without the need for field measurements, which require effort and time.

Opis:
Soil loss is a major problem for watersheds management in semi-arid environments. The objective of the present study is to analyze the annual and seasonal patterns of suspended loads and quantify the specific sediment yields in a semi-arid environment of the Mazafran Watershed in central Algeria. The obtained information of water discharge and suspended sediment load, recorded during 19 years, was confronted with precipitation data in order to establish the relationships between theforcing agents and erosive processes. The specific sediment yield was estimated by assessing rating curve data under two types of identified responses. The obtained results allowedconfirming the seasonality on suspended sediment transport in the studied basin, which accounts for 56% of the total suspended sediment load estimated in winter. The mean annual suspended sediment is estimated at 17.52 Mg∙ha–1·y–1. The results highlighted that the type 2 event dominates the production of sediment in the study area in comparison with type 1 event. The analysis of the variability of rainfall erosivity index showed that there is a strong correlation between the annual precipitation and modified Fournier index (MFI), and a weak correlation with the monthly precipitation concentration index (PCI). Moreover, the spatial distribution of the modified Fournier index at the basin scale showed the highest precipitation aggressiveness in the Southern part of the study region for both type of events, whereas the precipitation aggressiveness low to moderate in the remaining part of the study region.

Opis:
Biogeochemical and trophodynamic processes as well as hydrodynamic factors play a major role in the structure and function of mangrove ecosystems. This study outlines field experiments on wave motion and suspended sediment concentration carried out at Nang Hai, Can Gio mangrove forest, Southern Vietnam. Pressure sensors were used to measure sea surface elevation, and Optical Backscatter Sensors (OBS) were applied to detect infrared (IR) radiation scattered from suspended particles in order to measure turbidity and suspended sediment concentrations. The experimental results indicate that most of the energy is dissipated inside the mangrove forest as a result of wave-trunk interactions and wave breaking. The suspended sediment concentration depends on wave intensity and tidal current velocity. Wave action is one of the main factors forcing sediment transport and coastal erosion at the study site; even the wave field at the study site is not so strong. The establishment of mangrove vegetation can encourage the deposition of sediment, or at least the retention of the flood-tide sediment influx.

The study was carried out in the area of three dam reservoirs: Blizne and Maziarnia (Voivodeship of Podkarpackie) and Nielisz (Voivodeship of Lublin). The main parameter differentiating the reservoirs was the water retention time and the manner of water discharge from the reservoirs. Three test sites were designated in the area of each reservoir: in the river zone of the reservoir, in the central part of the reservoir, and near the reservoir dam. At these sites, the concentrations of suspended sediment in the water and the content of organic matter in it, the concentrations of total phosphorus and total nitrogen, as well as chlorophyll a were monitored. In addition, two control sites were established: on the river upstream of the reservoir and on the river downstream of the dam, respectively. At these points, the concentrations of suspended sediments in the water and their organic matter content were recorded. The obtained results of the study and multivariate analysis of the data showed that morphometric parameters (including water retention time) of reservoirs and the method of water discharge influence water quality in downstream rivers. It was found that by using lower discharge and ensuring a sufficiently long retention time of water in the reservoir, it is possible to effectively limit the negative aspects of hydrotechnical structures’ impact on the natural environment. In practice, the observed relationships may constitute an important and missing link in the aspect of minimising undesirable side effects of this type of hydrotechnical objects.

Opis:
In the Colorado River Delta, the interaction of tidal currents and sea-bottom sediment formed, in geological times, large-scale seabed patterns known as sandbanks. These patterns are oriented along the delta, almost parallel to the dominant tidal flow, with the bathymetry having an undulating character across the delta. Calculations and analysis showed that the interaction of tidal currents with the bathymetry causes velocity shears, faster flowing over the ridges than in the troughs. Kelvin-Helmholtz instabilities emerge from the velocity shear, and a large amount of suspended sediment makes the instabilities visible in satellite images. The physical and dynamic conditions allowed us to find an explanation for the existence of these Kelvin-Helmholtz instabilities. Since sandbanks have been observed in different seas such as the North Sea, The Gulf of Korea, the Gulf of Khambhat in India, the Jiangsu coast in China, the Persian Gulf, and Moreton Bay in Australia, the results suggest the existence of instabilities in these areas. Satellite images, intense tidal currents, undulating topography, and suspended sediment made it possible to explain the generation and identification of KelvinHelmholtz instabilities.
