Elevation data based on NASA’s Shuttle Radar Topography Mission (SRTM) have been widely used to evaluate threats from global sea level rise, storm surge, and coastal floods. However, SRTM data are known to include large vertical errors in densely urban or densely vegetated areas. The errors may propagate to derived land and population exposure assessments. We compare assessments based on SRTM d...

Coastal areas are among the most densely populated zones worldwide and at the same time subjected to rapid environmental changes due to their land-sea interface locations. The phenomenal growth of coastal tourism in the last few decades, especially in the tropical countries, has created environmental havocs by drastically altering the local ecological milieu in which the indigenous communities ...

Geomorphology, clay mineral composition, and radiocarbon dates from Muttukadu to Marakkanam estuaries and the tidal zone along the east coast of Tamil Nadu, India, have been used to reconstruct coastal evolution between approximately 4500 and 1100 BP. Formation of alternate oyster beds with intervening tidal clay units indicate fluctuation in the sea level may be a consequence of changes in the...

Debate exists on use of large-scale, simplified models for predicting shoreline change, e.g., IPCC AR6, as opposed to local-scale ‘compartment-based’ studies. An alternative is act both top-down and bottom-up, integrating multi-scale data. We outline a prototype ‘Omni-Line’ coastal database, spanning Victoria, Australia (2500 km coastline), part the Victorian Coastal Monitoring Program (VCMP). ...

Abstract Based on the current situation of frequent wind deflection faults 500 kV transmission line jumpers caused by typhoons in coastal areas, this paper proposes a new sectional proof post insulator transformation measure analyzing advantages and disadvantages conventional jumper measures, which effectively improves anti typhoon resistance jumpers. It can save amount steel for tower greatly ...

The southeastern United States harbors an unusually large number of endemic plant taxa, which may reflect the refugial nature of the region during Pleistocene glacial maxima. Understanding the genetic diversity and structure of extant plant taxa can provide insights into the biogeographical processes that shaped them genetically. Here, we investigate the levels and partitioning of allozyme dive...
