COASTLINE DETECTION USING FUSION OF OVER SEGMENTATION AND DISTANCE REGULARIZATION LEVEL SET EVOLUTION
Coastline DRLSE FOOS K-means Clustering Sea-land Segmentation Wavelet Transform
2018/4/18
Coastline detection is a very challenging task in optical remote sensing. However the majority of commonly used methods have been developed for low to medium resolution without specification of the ke...

THE EFFECT OF COASTLINE CHANGES TO LOCAL COMMUNITY’S SOCIAL-ECONOMIC
Coastline Changes Socio-economic Coastal Vulnerability Index
2016/10/14
The coastal area is absolutely essential for the purposes of resident, recreation, tourism, fisheries and agriculture as a source of socio-economic development of local community. Some of the activiti...
A multisource approach for coastline mapping and identification of shoreline changes
coastline mapping satellite GPS tide multitemporal analysis
2015/9/7
Coastal dynamics are driven by phenomena of exogenous and endogenous nature. Characterizing factors that influence their equilibrium and continuous monitoring are fundamental for effective environment...
Temporal variation of 134Cs and 137Cs activities in surface water at stations along the coastline near the Fukushima Dai-ichi Nuclear Power Plant accident site, Japan
radiocaesium ocean coast Fukushima geochemistry
2017/4/11
We present our April to December 2011 observations of 134Cs and 137Cs activities in surface water at Hasaki, a coastal
station 180 km south of the Fukushima Dai-ichi Nuclear Power Plant (FNPP1) accid...
Changes in the Shoreline Position Caused by Natural Processes for Coastline of Marsa Alam – Hamata, Red Sea, Egypt
Shoreline Changes Red Sea Satellite Images Climate Changes Coastal Processes
2013/3/7
The probability of storms and ice-drift events and their impact on coasts is expected to increase as result of climate change. Multi-years shoreline mapping is considered a valuable task for coastal m...
Continental Shelf Waves and Alongshore Variations in Bottom Topography and Coastline
Continental Shelf Waves Bottom Topography Alongshore Variations Coastline
2009/3/7
The effects of alongshore variations in bottom topography and coastline on the wind-stress-forced barotropic motion over a continental shelf and slope are studied. Perturbation methods are used to obt...
We examine the generation of trapped edge waves on a continental shelf when a long wave from the deep ocean reaches an irregular coast, and alterations in the propagation characteristics of trapped ed...
The Effects of a Variable Coriolis Parameter, Coastline Curvature and Variable Bottom Topography on Continental Shelf Waves
Variable Coriolis Parameter Coastline Curvature Variable Bottom Topography Continental Shelf Waves
2009/3/7
The effects of a variable Coriolis parameter, coastline curvature and variable bottom topography on continental shelf waves are examined for the case when the variations occur on a length scale much g...
Transient Upwelling Generated by Two-Dimensional Atmospheric Forcing and Variability in the Coastline
Transient Upwelling Variability Two-Dimensional Atmospheric Forcing
2009/2/8
The present paper deals with two-dimensional transient upwelling in a two-layer ocean of constant depth. Motions generated by several two-dimensional atmospheric forcings are investigated. Using asymp...
A Numerical Study of the Effects of Coastline Geometry on Wind-Induced Upwelling in the Gulf of Lions
Coastline Geometry Wind-Induced Upwelling Gulf of Lions
2009/2/5
An attempt is made to explain the fixed locations of coastal upwelling centers in the Gulf of Lions as a function of the coastline geometry alone. The semi-implicit numerical model, based on two-layer...
The shallow water equations applied to a two-layer ocean are solved in order to study the cited of capes on upwellings. First, analytical solutions of the linearized version of these equations are giv...

Topographically-Induced Baroclinic Eddies Coastline Northeast Pacific
2009/1/16
A mathematical model is developed to describe the interaction between variable bottom topography and a steady, horizontally-sheared baroclinic coastal current. The topography modeled in this study con...
Separation of an Inertial Boundary Current from a Curved Coastline
Inertial Boundary Current Curved Coastline
2009/1/10
A two-layer model is used to examine the separation of an inertial boundary current from a curved coastline and its subsequent path as a free jet. To isolate the inertial effect, the boundary current ...
