What is shoreline topography?
What is shoreline topography?
A shore or a shoreline is the fringe of land at the edge of a large body of water, such as an ocean, sea, or lake. Shores are influenced by the topography of the surrounding landscape, as well as by water induced erosion, such as waves.
What are shoreline features?
Shore platform, sea cave, sea arch, and sea stack. Shore Platform. A narrow flat area often found at the base of a sea cliff or along the shoreline of a lake, bay, or sea. Created by the action of waves.
How shoreline features are formed?
But, the shoreline itself is the direct interface between water and land that shifts with the tides. This shifting interface at the shoreline is called the littoral zone. The combination of waves, currents, climate, coastal morphology, and gravity, all act on this land-sea boundary to create shoreline features.
What is shoreline mapping?
The California Shoreline Mapping Program will create a modern elevation map of the state’s coastline (shore to 10 meters in elevation) to help coastal communities understand and prepare for sea level rise and severe storms. …

How is shoreline defined?
A shoreline is the edge of a sea, lake, or wide river.
What is the most common depositional shoreline feature?
The most familiar feature of a depositional coast is the beach (Figure 11.11). A beach is a zone of unconsolidated (loose) particles that covers part or all of a shore.
Which are major erosional shoreline features?
Landforms of erosional coasts
- Sea cliffs. The most widespread landforms of erosional coasts are sea cliffs.
- Wave-cut platforms. At the base of most cliffs along a rocky coast one finds a flat surface at about the mid-tide elevation.
- Sea stacks.
- Sea arches.
What are the two types of coastlines?
A cliffed coast or abrasion coast is one where marine action has produced steep declivities known as cliffs. A flat coast is one where the land gradually descends into the sea. A graded shoreline is one where wind and water action has produced a flat and straight coastline.
How are coastlines mapped?
The first was a nautical (or hydrographic) survey, which mapped the depths of coastal waters and offshore hazards. The other was a topographic survey, which mapped the land, including the shoreline, natural and cultural features, and elevations above the sea.
What’s the difference between a coastline and shoreline?
The term coastline and shoreline are both boundary lines between water and land. The term coastline is generally used to describe the approximate boundaries at relatively large spatial scales. Shoreline is used to describe the precise location of the boundary between land and water.

Which is the best source for shoreline data?
Source Data: T-sheets, which are special-use planimetric or topographic maps that precisely define the shoreline and alongshore natural and man-made features, such as rocks, bulkheads, jetties, piers, and ramps. Where T-sheets are unavailable, NOAA’s extracted vector shoreline (EVS) was used to compile seamless shoreline coverage.
How is the morphology of a shoreline affected?
Shoreline morphology and expression are affected by many factors that are active during shoreline development and post-depositional modification. When water disappears from a basin, the area is likely to only preserve the last phases, obscuring an understanding of the older processes.
What are the features shown on a topographic map?
Topographic map. –A topographic map, as distinguished from other kinds, portrays by some means the shape and elevation of the ter rain. Geological Survey topographic maps usu ally represent elevations and laNdforms–the shapes into which the earth’s surface is sculp tured by natural forces–by contour lines.
How are linear shoreline features distinguishable in remote imagery?
Linear shoreline features may be distinguishable in remote imagery with only 2 m horizontal resolution and 1 m vertical resolution, a scale that is presently available in areas covered by HiRISE images in some portions of Mars. Slope may be an important factor in shoreline development and expression.
