Abstract
In this study, the performances of the decision tree forest and group method of data handling for evaluation scale of the severity (SEV) of ill effect for fishes were investigated. The independent variables were concentration of suspended sediment (SS), species, life stage, and duration of exposure. This study is based on 198 data of aquatic ecosystem quality over a wide range of sediment concentrations (1–500,000 mg SS/L) and durations of exposure (1–35,000 h). Results showed that exposure duration is the most important factor on SEV, and based on the results, this alternative approach is better than traditional regression models with a higher recognition rate, forecast accuracy, and strong practical value.
期刊介绍：
The Water Quality Research Journal publishes peer-reviewed, scholarly articles on the following general subject areas:
Impact of current and emerging contaminants on aquatic ecosystems
Aquatic ecology (ecohydrology and ecohydraulics, invasive species, biodiversity, and aquatic species at risk)
Conservation and protection of aquatic environments
Responsible resource development and water quality (mining, forestry, hydropower, oil and gas)
Drinking water, wastewater and stormwater treatment technologies and strategies
Impacts and solutions of diffuse pollution (urban and agricultural run-off) on water quality
Industrial water quality
Used water: Reuse and resource recovery
Groundwater quality (management, remediation, fracking, legacy contaminants)
Assessment of surface and subsurface water quality
Regulations, economics, strategies and policies related to water quality
Social science issues in relation to water quality
Water quality in remote areas
Water quality in cold climates
The Water Quality Research Journal is a quarterly publication. It is a forum for original research dealing with the aquatic environment, and should report new and significant findings that advance the understanding of the field. Critical review articles are especially encouraged.
