Due to a shortage of available phosphorus (P)-loss datasets, simulated data from an accurate quantitative P transport model could be used to evaluate a P Index. The objective of this study was to compare predictions from the Texas Best Management Practice Evaluation Tool (TBET) against measured P-loss data to determine whether the model could be used to improve P Indices in the southern region....

Long-term streamflow simulations of the Land Surface Models (LSMs) are necessary for comprehensive evaluation hydrological responses to climate change. The high complexity and uncertainty in LSM modelling require model calibration improve simulation performance stability. Objective functions commonly used process, choice objective plays a crucial role identification. Kling Gupta Efficiency (KGE...

Obtaining more accurate flood information downstream of a reservoir is crucial for guiding regulation and reducing the occurrence disasters. In this paper, six popular ML models, including support vector regression (SVR), Gaussian process (GPR), random forest (RFR), multilayer perceptron (MLP), long short-term memory (LSTM) gated recurrent unit (GRU) were selected compared their effectiveness i...

Abstract In the present study, a new hybridization strategy for predicting groundwater table (GWT) and drought analysis is presented. Therefore, hybrid of bi-directional long short-term model (BLSTM) Harris hawk optimization (HHO) algorithm, namely BLSTM–HHO applied. this lagged data GWT are used as input, whereas current output. Additionally, standalone BLSTM, (LSTM), artificial neural network...

This study evaluated the reduction effect of non-point source pollution by applying best management practices (BMPs) to a 1.21 km2 small agricultural watershed using a SWAT (Soil and Water Assessment Tool) model. Two meter QuickBird land use data were prepared for the watershed. The SWAT was calibrated and validated using daily streamflow and monthly water quality (total phosphorus (TP), total ...
