The visibility of retail frontages is critical for earning profits from spontaneous traffic visits to shops located along a street. urban tree canopy plays crucial role in enhancing the street-side environment, yet more not always better when considering placement behind trees with big canopies. Related evidence literature rarely provided, and an unclear relationship has been reported exist between number specific type quantified ratio shade street view. In this study, both data crawling deep learning were employed unravel Changchun, Northeast China. entire study area was divided into 6037 grid cells side length ~0.6 km, wherein five types (food beverage, shopping, life services, entertainment, hotel) by computer counting their points interest (POIs). evaluated using green view index (GVI) through pixels all image obtained online map API. A neighboring road network categorized four classes: class I density mainly reduced shops, densities classes III IV accounted shops. GVI could be fitted positive skewness curves II roads, where peak estimated about 3.27%. optimization scheme indicated that should placed roads. conclusion, food services landscape

This study employs convolutional neural network (CNN), long short-term memory (LSTM), bidirectional (BiLSTM), and gated recurrent unit (GRU) deep learning models to simulate daily streamflow using precipitation data. Two approaches were explored: one without dimension reduction another incorporating dimensionality technique. Principal component analysis (PCA) was employed for reduction, partial autocorrelation function (PACF) used determine time lags. An augmented Dickey–Fuller (ADF) test utilized ascertain the stationarity of data, ensuring optimal model performance. The data normalized then partitioned into features target variables, before being split training, validation, sets. developed tested their performance, robustness, stability at three locations along Neuse River, which is in River Basin, North Carolina, USA, covering an area about 14,500 km2. Furthermore, model’s performance during peak flood events assess ability capture temporal resolution streamflow. results revealed that CNN could variability prediction, as evidenced by excellent statistical measures, including mean absolute error, root square Nush–Sutcliffe efficiency. also found significantly improved

Accurate streamflow prediction in mountainous regions is vital for sustaining water resources downstream areas, ensuring reliable availability agriculture, energy, and consumption. However, physically based models are prone to substantial uncertainties due complex processes the inherent variability model parameters parameterization. This study addresses these challenges by exploring alternative coupling inputs data-driven (DD) optimize daily a calibrated SWAT-BiLSTM rainfall-runoff within Astore sub-basin of Upper Indus Basin (UIB), Pakistan. The research explores two standalone (SWAT BiLSTM) three inputs: conventional climatic variables (precipitation temperature), cross-correlation selected inputs, exclusion direct model. spans calibration, validation, periods from 2007 2011, 2012 2015, 2017 2019, respectively. Based on compromise programing (CP) ranking, SWAT-C-BiLSTM (Q P ) (T 1 Q showed competent performances followed BiLSTM, (PTQ ), SWAT. These findings highlight that excluding enhances couple model’s accuracy sufficiently underscores potential this approach contribute sustainable resource management.

The aim of this study is to evaluate the current water quality status one urban rivers in Malaysia, called Sungai Air Hitam. river's supply not only unsuitable for inhabitants but also hazardous aquatic species that depend on it. In order simulate formulation river, Model Urban Stormwater Improvement Conceptualization (MUSIC) was used. effects various best management practices (BMPs) components have been examined improve quality. This investigated different scenarios expected future changes land cover and river. As proportion impervious surfaces increases, hydrology cycle can be significantly altered, resulting an increase volumes peak flows, a decrease storage, infiltration, interception. MUSIC results shown significant reductions biochemical oxygen demand (BOD), total suspended solids (TSS), phosphorus (TP), nitrogen (TN) after introducing BMPs. It noticed prediction pollutants falls within acceptable range set by Management Manual Malaysia (MSMA) 2nd edition. For cover, it found reduction BOD, TSS, TP, TN existing use 92.5 %, 94.5 90.7 % 91.9 %. Meanwhile, 81.6 86.2 80.9 TP 80.8 TN. From simulation results, observed application BMPs has successfully reduced mean BOD concentration from 92.38 mg/L (Class V) 6.93 IV) national standards, NWQS, index. result, index overall catchment improved Class IV III (WQ1, WQ3, WQ4) V (WQ2) with assessment aims raise awareness Hitam community regarding importance preserving river cleanliness understanding long-term environmental impact These findings underscore integrated system managing systems, which offer valuable insight decision-makers.
