Strategic intervention, sustained monitoring, and community engagement can restore water quality and public health outcomes. Implications for Coastal Waterbody Management The Chilmark case shows that an integrated approach combining real-time monitoring, ultrasonic bloom prevention, dredging, and nutrient management can achieve rapid bloom control and ecosystem health ...
Introduction What is a LiDAR Payload? LiDAR stands for Light Detection and Ranging and has become an increasingly prevalent technology over the past decade. NASA and meteorologists have used LiDAR, now embedded within cell phones with the release of the iPhone 12 Pro. LiDAR is commonly used in surveying, mapping, and inspection applications where it can provide very detailed and accurate ...
Frequently based on static models using network averages, such methods risk missing developing corrosion issues and consequent odour and safety risks. ...
With the latest release of the AERMOD model dated 22112, the U.S. EPA has continued to expand the formulated capabilities of the model. Most of these updates have been added as ALPHA non-default options, a concept we covered in a previous modeling tip. AERMOD 22112 contains 6 new ALPHA options which are described below: Platform Downwash Taken ...
In this paper, two shortcomings with the adaptive network-based fuzzy inference system (ANFIS) model for prediction of wave parameters are remedied by employing a genetic algorithm (GA). ...
A surrogate modeling framework is developed in this study to circumvent the computational burden of high-fidelity numerical groundwater models for arid coastal aquifers. Two different surrogate models, namely, artificial neural network (ANN) and Gaussian process model (GPM) are trained to replace the ...
Computer models that help oceanside cities plan for their future also hold hope for a threatened coastal ecosystem. ...

Accurate and reliable prediction of groundwater level is a critical component in coastal water management. It is important to find a suitable model with acceptable accuracy. This paper presents a comparative study with seasonal decomposition method of time series analysis and GM (1,1) method, which are applied to test the model accuracy by ...
Managing combined sewage systems in large cities discharging to coastal waters, often bearing recreational activities, remains a challenge. Studying the impacts of such discharges requires the development of specific models. Hydrodynamic and water quality modelling of coastal waters employs numerical methods and algorithms, ...
An important tool in environmental management projects and studies due to the complexity of environmental systems, environmental modeling makes it possible to integrate many variables and processes, thereby providing a dynamic view of systems. In this study the bacteriological quality of the coastal waters of Fortaleza (a state capital in Northeastern Brazil) ...
Coastal aquifers are always under threat of seawater intrusion due to over-extraction of groundwater. The objective here is to assess aquifer response to variation in pumping and rainfall recharge due to projected climate change by groundwater modelling in a heavily exploited aquifer. Finite element groundwater flow modelling was carried out ...
Watershed models are typically calibrated and validated with the same land use and land cover (LULC) dataset and later used in assessing impacts of changing LULC, such as urbanization, on hydrology and/or water quality. ...
The importance of fisheries continues to rise as coastal populations are increasing, and rapidly growing economies are driving up demand for fish. ...
We apply the chemical speciation model WHAM/Model VII to investigate the distribution of metal species of Fe(III) and the divalent cations of Ni, Cu, Zn, Cd, Hg and Pb, in the water column of estuaries and coastal areas. ...
A mathematical eutrophication model, EnvHydrEM (Environmental Hydraulics Institute Eutrophication Model), was developed to be applied specifically to coastal lagoons. ...
These situations increase the complexity of the hydrodynamic regime, requiring the use of numerical models to understand their behaviour. Traditionally, one-dimensional models have been used, although in recent years, the development of two-dimensional shallow water models and advanced numerical techniques have increased notably. ...
However, they can only be applied if the model can be calibrated using observed data. This paper presents a geographic information system (GIS)-based method to calculate the sediment discharge from basins to coastal areas. ...
The water resources of the Essaouira basin are characteristic of a semi–arid climate. It is a coastal aquifer located on the Atlantic coastline, corresponding to a sedimentary basin with an area of about 200 km². ...
Nowadays, there are several remote sensing techniques that can be used as a source to derive bathymetry data along coastal areas. The key techniques are: sonar (sound navigating and ranging), LiDAR (light detection and ranging) and high-resolution satellite images. ...
The coastal region experiences erosional, transportational and depositional events during mega events such as tsunami. The onshore deposits are significant in determining the past events of high–energy events in the coastal region. The Optically Simulated Luminescence (OSL) dating of the sediments by combining Ground Penetrating Radar (GPR) records will reveal the past tsunami events. OSL dates ...
