Artificial Intelligence (AI) is the technology everyone is talking about this year, and it is a trend that water utilities cannot ignore. However, how can artificial intelligence really help in water cycle management? Artificial intelligence is one of the most important and exciting technologies of the 21st century. In fact, it has increased its ranking in the main search engines by 139% ...

Meteorologists deploy networks of these systems along coasts and in the eyes of storms to enhance individual observation accuracy and predictive capability of hurricane forecasts. Existing challenges in storm tracking Hurricanes have always been difficult to predict. ...
It was specified that the solution must provide operations functionality for locations without power supply from the grid, measured and forecasted water level, visual monitoring, and early warning and alert management. The main objective of this project was to provide the best water level prediction system, and ...
The PTM has been turned into the following devices by pairing it with different sensors: a radar-based water level gauge, a rain gauge, a weather station, a time-lapse camera, a wave buoy and a water quality buoy. ...
But if this happens often when the forecast points to a low probability, then the forecast provider will quickly be distrusted. ...
Emergency Operations Centre Director Chris Marsh says rivers weren’t up as much as forecast Wednesday, but that could change quickly with intense storms. ...
Modeling of hydrological time series is essential for sustainable development and management of lake water resources. This study aims to develop an efficient model for forecasting lake water level variations, exemplified by the Poyang Lake (China) case study. ...
Numerical modeling is one of the popular means to simulate and forecast the state of oceanographic systems. However, it still suffers from some limitations, e.g., parameter uncertainties, simplification of model assumptions, and absence of data for proper boundary and initial conditions. This paper proposes a hybrid data assimilation scheme, which combines the Kalman filter (KF) with a ...
A combination of self-organising maps (SOM) and multi-layer perceptron artificial neural networks (MLP-ANN) is applied to the Lower Shire floodplain of Malawi for flow and water level forecasting. The SOM was used to extract features from the raw data, which then formed the basis of infilling the gap-riddled data to provide more complete and much ...
Previous predictions of children's blood lead levels (BLLs) through biokinetic models conclude that lead in tap water is not a primary health risk for a typical child under scenarios representative of chronic exposure, when applying a 10 μg/dL BLL of concern. Use of the US Environmental Protection Agency Integrated Exposure Uptake Biokinetic (IEUBK) model and of the International ...
This paper proposes a practical approach of a neuro-genetic algorithm to enhance its capability of predicting water levels of rivers. Its practicality has three attributes: (1) to easily develop a model with a neuro-genetic algorithm; (2) to verify the model at various predicting points with different conditions; and (3) to provide information for making urgent decisions on the operation of ...
This paper presents a probabilistic approach for modelling uncertainty from single-valued QPFs at different forecast lead times. The uncertainty models in the form of probability distributions of rainfall forecasts combined with a sewer model is an important advancement in real-time forecasting at the urban scale. ...
Model-based short-term forecasting of urban storm water runoff can be applied in real-time control of drainage systems in order to optimize system capacity during rain and minimize combined sewer overflows, improve wastewater treatment or activate alarms if local flooding is impending. A novel online system, which forecasts flows and ...
Incorporating weather forecasts in the control of land surface water levels requires predictions of the net inflow to the water system. ...
Ground water is underlying natural resources widely distributed under the ground and not visible from the earth surface. Prediction of state of groundwater table is very important for water resources planning and management. To estimate this valuable natural resource, indirect methods have been adopted since past decades. An artificial neural network (ANN) and neuro–fuzzy network (NFN) model both ...
The prediction of groundwater levels in a basin is of immense importance for the management of groundwater resources. In this study, support vector machines (SVMs) is used to construct a ground water level forecasting system. Further the proposed SVM–PSO model is employed in estimating the groundwater level of ...
The potential to improve flood simulation and forecasting by the use of predicted rainfall data based on radar measurements (virtual gauge) was investigated in two projects. Thus, water level in water bodies could be ...
Gravity drainage of oil with gas is an efficient recovery method in strongly water–wet reservoirs and yields very low residual oil saturations. However, many of the oil–producing reservoirs are not strongly water–wet. Thus, predicting the profiles and ultimate recovery for mixed and oil–wet media is essential to design and optimisation of improved recovery methods based on three–phase gravity ...
Forecasting the ground water level fluctuations is an important requirement for planning conjunctive use in any basin. ...
