Precise prediction of water quality parameters plays a significant role in making an early alert pollution and better decisions for the management resources. As one influential indicative parameters, electrical conductivity (EC) has crucial calculating proportion mineralization. In this study, integration adaptive hybrid differential evolution particle swarm optimization (A-DEPSO) with neuro fuzzy inference system (ANFIS) model is adopted EC prediction. The A-DEPSO method uses unique mutation crossover processes to correspondingly boost global local search mechanisms. It also refreshing operator prevent solution from being caught inside optimal solutions. This study optimizer ANFIS training phase eliminate defects predict accurately parameter every month at Maroon River southwest Iran. Accordingly, recorded dataset originated Tange-Takab station 1980 2016 was operated develop ANFIS-A-DEPSO model. Besides, wavelet analysis jointed proposed algorithm which original time series disintegrated into sub-time through two mother wavelets certainty. following, comparison between statistical metrics standalone ANFIS, least-square support vector machine (LSSVM), multivariate regression spline (MARS), generalized neural network (GRNN), wavelet-LSSVM (WLSSVM), wavelet-MARS (W-MARS), wavelet-ANFIS (W-ANFIS) wavelet-GRNN (W-GRNN) models implemented. result, it apparent that not only W-ANFIS-A-DEPSO able rise remarkably certainty, but (R = 0.988, RMSE 53.841, PI 0.485) had edge over other Dmey terms Moreover, can improve compared ANFIS-DEPSO model, accounting 80%. Hence, create closer approximation value likely act as promising procedure simulate data.

Tai Lake, the third largest freshwater lake in China, with a history of serious ecological pollution incidents. Lake water quality prediction techniques are essential to ensure an early emergency response capability for sustainable management. Herein, effective data-driven ensemble model was developed predicting dissolved oxygen (DO) based on meteorological factors, indicators and spatial information. First, variation mode decomposition (VMD) used decompose data into multiple modal components classify them feature terms self terms. The were combined relevant external features multivariate by convolutional neural network (CNN) bi-directional long short-term memory (BiLSTM) attention mechanism (AT), as well using whale optimization algorithm (WOA) optimize hyperparameters. form secondary model. Finally, groupings linearly summed obtain outcome. proposed has highest accuracy best effect 0.5 days period. This research also establishes stepwise temperature regulation mechanism, where output target DO content value is achieved changing magnitude combining it this model, thereby strengthening protection resources management fishery production.

Abstract Identifying and measuring potential sources of pollution is essential for water management control. Using a range artificial intelligence models to analyze quality (WQ) one the most effective techniques estimating index (WQI). In this context, machine learning–based are introduced predict WQ factors Southeastern Black Sea Basin. The data comprising monthly samples different were collected 12 months at eight locations Türkiye region in Sea. traditional evaluation with WQI surface was calculated as average (i.e. good WQ). Single multiplicative neuron (SMN) model, multilayer perceptron (MLP) pi-sigma neural networks (PS-ANNs) used WQI, accuracy proposed algorithms compared. SMN model PS-ANNs prediction modeling first time literature. According results obtained from ANN models, it found provide highly reliable approach that allows capturing nonlinear structure complex series thus generate more accurate predictions. analyses demonstrate applicability instead using other computational methods both particular resources general.
