Seagrasses are typically light limited in many turbid estuarine systems. Light attenuation is due to water and three optically active constituents (OACs): nonalgal particulates, phytoplankton, and colored dissolved organic matter (CDOM). Using radiative transfer modeling, the inherent optical properties (IOPs) of these three OACs were linked to the light attenuation coefficient, KPAR, which was...

These are the guidelines for the program Generalised Regression Neural Networks (GRNNs). Engineering has been researching the use of artificial neural networks (ANNs) for water resources modeling applications, such as flow forecasting, water quality forecasting and water treatment process modeling since the early 1990s. While Multi‐Layer Perceptrons (MLPs) are the most widely used ANN architect...

The bioavailability and toxicity of copper (Cu) in Shelter Island Yacht Basin (SIYB), San Diego, CA, USA, was assessed with simultaneous toxicological, chemical, and modeling approaches. Toxicological measurements included laboratory toxicity testing with Mytilus galloprovincialis (Mediterranean mussel) embryos added to both site water (ambient) and site water spiked with multiple Cu concentrat...

fuzzy water quality index (fwqi) was applied in order to assess the degree of drinking water resources in yazd province, iran. thisstudy has also offered the creation of a new fuzzy water quality index (fwqi) to evaluate this tool’s applicability. 12 chemicalparameters including toxic and non-toxic heavy metals measured in 71 groundwater samples collected from drinking water resourcesin rural a...

Traffic accidents sometimes lead to the spread of hazardous compounds to the environment. Accidental spills of hazardous compounds on roads in the vicinity of vulnerable objects such as water supplies pose a serious threat to water quality and have to be assessed. This study compared three different assessment methods, electrical resistivity measurements, analytical flow calculations, and 1D an...

The collective impacts of rapid urbanization, poor pollution management practices and insufficient sanitation infrastructure have driven the water quality deterioration in Little Akaki River (LAR), Ethiopia. Water modeling using QUAL2Kw was conducted LAR aimed at selecting optimal improvement load reduction approaches based on evaluation five scenarios: modification point sources (PS) (S1), non...

background: desalination plants have an important role in providing community drinking water. the increasing trend of water consumption and decrease of natural resources of fresh water make this role even more important. the aim of this study was to evaluate the quality of inlet and outlet water of desalination plants by reverse osmosis (ro) process in qeshm, iran and also to compare the qualit...

background: due to the lack of proper rail road and air transportation, most commutes in iran are carried out by buses. in most cases, the water in the busses is used for passengers for drinking usage. although this kind of water source has provided convince for the travelers, it could be a great risk in disease outbreak. the aim of this study is to determine the water quality in commuting buse...

the zarivar lake a freshwater lake in west of kurdistan province is home for large number of native plant and animal species therefore water quality and health of the lake are vital for conservation of these species. the present study aimed at evaluation of the zarivar lake using nsf- wqi as an indicator of water quality. wqi is a suitable tool to examine and classify spatial and temporal varia...
