UTILIZING GIS TO RELATE SPATIAL AND TEMPORAL DYNAMICS OF THE EMERGENT EAST ASIAN COAST

The natural sedimentation rates and geomorphology of the Yellow (Huang He) River are well documented; these have not been related across time and space in a GIS and existing models fail to address human influences. The Yellow River, for example, no longer flows into the ocean for a large portion of the year due to increased water consumption by industry, agriculture, and a growing population in the last 20 to 30 years. The Yellow River delta's shift from rapid accretion (fueled by its traditionally large sediment load) to coastal erosion is a dramatic shift in the development of coastal morphology with profound societal repercussions. Historical maps and remotely sensed data will be used to create a GIS model to determine impacts of river change on the East Asian coastline using a multi-scale approach. Historical maps create a long record of spatial change, but with only a few temporal intervals. Satellite images, however, construct a scale with a short temporal record (30 years), but provide a high degree of precision within those confines both temporally and spatially.
