A two-dimensional water-quality model for a winding and topographically complicated river

Article Abstract:

The article examines a two-dimensional, numerical calculation algorithm method for assessing water quality management at the Xiangjiang River in China's Hunan Province. The approach involves a finite element method and topographical map data of the river's course to project water quality.

Incorporation of inexact dynamic optimization with fuzzy relation analysis for integrated climate change impact study

Article Abstract:

The fuzzy relation analysis (FRA) technique provides a means of analysing general climate change impact patterns based on the outputs of an inexact dynamic optimization (IDO) approach. The IDO approach reveals uncertain, dynamic and interactive features of the study of climate change impact assessment. The FRA method helps in understanding relations between the components of the study system. The IDO and FRA approaches reveal the complex nature of climate change impacts, such as temporal variations of land features and land uses. Canada's Mackenzie Basin is studied.
