Approach to Dynamic Wetland Modelling in GIS
ByCarsten Bjornsson
Pages 14

Developing wetlands to improve water quality involves the analysis of existing hydrological conditions, which are often characterised by time and space variations and discrete sample points. To bring about spatial continuity, hydrologic and water quality models has been developed and implemented using GIS. In respect to spatial distribution these GIS models are often based on one-dimensional network algorithms or surfaces with a many-to-one spatial relationship and some level of accumulation of flows. Some hydrologic movements in space are described by a many-to-many relationship characterised by types of behaviour like dispersion, diffusion, etc.
