In metropolitan regions made up of multiple independent jurisdictions, adaptation to increased coastal flooding due to sea level rise requires coordinated strategic planning of the physical and organizational approaches to be adopted. Here, we explore a flexible method for estimating physical adaptation costs along the San Francisco Bay shoreline. Our goal is to identify uncertainties that can ...
A simple analytical method was developed to estimate external doses from exposure to contaminated riverine shorelines. The method consists of deriving an adjustment factor that accounts for the geometry of the riverine shoreline; the adjustment factor is applied to the dose-rate coefficients already available for infinite contaminated surfaces. Such a geometry factor circumvents very complex ra...
Tõnisson, H.; Suursaar, Ü.; Orviku, K.; Jaagus, J.; Kont, A.; Willis, D.A. and Rivis, R., 2011. Changes in coastal processes in relation to changes in large-scale atmospheric circulation, wave parameters and sea levels in Estonia. Journal of Coastal Research, SI 64 (Proceedings of the 11th International Coastal Symposium), . Szczecin, Poland, ISSN 0749-0208 Estonia is sensitive to climate chang...
During any marine oil spill, floating oil slicks that reach shorelines threaten a wide array of coastal habitats. To assess the presence of oil near shorelines during the Deepwater Horizon (DWH) oil spill, we scanned the library of Synthetic Aperture Radar (SAR) imagery collected during the event to determine which images intersected shorelines and appeared to contain oil. In total, 715 SAR ima...
We report here a four decades of shoreline changes and possible sea level rise (SLR) impact on land use/land cover (LULC) in Little Andaman Island by using remote sensing (RS) Geographic Information System (GIS) techniques. A total six data sets covering years between 1976 2018 were used to understand the changes. Moreover, Digital Shoreline Analysis (DSAS) was estimate short- long-term from Ar...
As one of the most sensitive factors in sea–land interaction zone, shoreline is significantly influenced by natural processes and anthropogenic activities. Monitoring long-term changes offers a basis for integrated management protection coastal zones. The spatiotemporal distribution utilization types shorelines had changed lot, along with advancement socioeconomics countries around South China ...
Time-series remote sensing data, sediment cores, and water column profiles of fluid properties and suspended sediment concentration were utilized to examine the mechanisms and volumes of sediment exchange between the mangrove fringe and the coastal zone in French Guiana. Remote sensing estimates of sediment yield from mangrove shoreline erosion by wave attack during the f 30-year periods when o...
