Emergent behavior in a coupled economic and coastline model for beach nourishment
Developed coastal areas often exhibit a strong systemic coupling between shoreline dynamics and economic dynamics. “Beach nourishment”, a common erosion-control practice, involves mechanically depositing sediment from outside the local littoral system onto an actively eroding shoreline to alter shoreline morphology. Natural sedimenttransport processes quickly rework the newly engineered beach, ...
متن کاملMacrofaunal sediment selectivity considerations for beach nourishment programmes.
Nowadays, beach nourishment is widely considered as a better alternative compared to the construction of hard structures to protect a sandy coast against detrimental erosive effects, both from an ecological and an engineering perspective. The rare studies conducted on the ecological impact of beach nourishment are short-term, post hoc monitoring investigations of the benthic macrofauna. Little ...
متن کاملEnvironmental Impact of Beach Nourishment: A Case Study of the Rio San Pedro Beach (SW Spain)
The beaches on the left bank of Rio San Pedro (SW Spain) are in a regressive state because of the human activities of recent decades. With the objective of minimizing the effects of the erosion, the Spanish Coastal Department (Ministry of the Environment) decided that the most suitable solution was to provide sand nourishment. Previously, an environmental impact study (EIS) was carried out on t...
متن کاملThe Economic Benefits from Immigration
T he rapid increase in the size of the immigrant flow reaching the United States, the major changes in the national origin composition of the immigrant population, and the decline in the skills of immigrants relative to the skills of native workers have rekindled the debate over immigration policy. The current debate revives the old concerns over immigrants "taking jobs away" from native worker...
متن کاملSemi-Automated Monitoring of a Mega-Scale Beach Nourishment Using High-Resolution TerraSAR-X Satellite Data
This paper presents a semi-automated approach to detecting coastal shoreline change with high spatialand temporal-resolution using X-band synthetic aperture radar (SAR) data. The method was applied at the Sand Motor, a “mega-scale” beach nourishment project in the Netherlands. Natural processes, like waves, wind, and tides, gradually distribute the highly concentrated sand to adjacent beaches. ...
