Summary
Coastal spits and shoals can grow seaward even with strong wave action if wave energy is insufficient to move incoming sand. These formations exhibit unique shapes and ripple patterns not aligned with wave crests.
Area of Science:
- Coastal geomorphology
- Sedimentary processes
- Oceanography
Background:
- Littoral drift supplies sand for coastal formations.
- Refracted wave attack influences coastal morphology.
- Wave energy is a critical factor in sediment transport.
Purpose of the Study:
- To investigate the conditions under which spits and shoals grow seaward.
- To identify distinctive morphological features of these coastal formations.
- To analyze the relationship between wave energy, sand supply, and ripple mark formation.
Main Methods:
- Observational analysis of coastal geomorphology.
- Sedimentological analysis of spit and shoal formations.
- Wave energy assessment in relation to littoral drift.
Main Results:
- Spits and shoals can accrete seaward when wave energy is too low to overcome sand supply from littoral drift.
- These formations display characteristic shapes influenced by low wave energy conditions.
- Ripple marks on these features may form at angles oblique to the dominant wave crests.
Conclusions:
- Low wave energy environments can facilitate seaward growth of spits and shoals.
- Distinctive geomorphological features, including oblique ripple marks, characterize these formations.
- Understanding wave-sediment dynamics is key to predicting coastal evolution.

02:18Interference and Diffraction
Interference is a characteristic phenomenon exhibited by waves. When two electromagnetic waves interact with their peaks and troughs coinciding, a resulting wave with enhanced amplitude is produced. This is known as constructive interference. In this case, the two waves interacting are in phase with each other.
01:07Propagation of Waves
When a wave propagates from one medium to another, part of it may get reflected in the first medium, and part of it may get transmitted to the second medium. In such a case, the interface of the two mediums can be considered as a boundary that is neither fixed nor free.
Consider a scenario where a wave propagates from a string of low linear mass density to a string of high linear mass density. In such a case, the reflected wave is out of phase with respect to the incident wave, however the...

01:07Reflection of Waves
When a wave travels from one medium to another, it gets reflected at the boundary of the second medium. A common example of this is when a person yells at a distance from a cliff and hears the echo of their voice. The sound waves (longitudinal waves) traveling in the air are reflected from the bounding cliff. Similarly, flipping one end of a string whose other end is tied to a wall causes a pulse (transverse wave) to travel through the string, which gets reflected upon reaching the wall. In...
01:16Shock Waves
While deriving the Doppler formula for the observed frequency of a sound wave, it is assumed that the speed of sound in the medium is greater than the source's speed through it. When this condition is breached, a shock wave occurs.
When the source's speed approaches the speed of sound, constructive interference between successive wavefronts emitted by the source occurs immediately behind it. Initially, scientists believed that this constructive interference would result in such high pressures...

01:21Partial Differential Equations
A stone dropped into a still pond generates waves that propagate outward in circular patterns, creating a dynamic surface whose elevation depends on both position and time. At any given location, the water level oscillates as the wave passes, while at any fixed moment, the surface exhibits smooth, curved structures extending across space. This dual dependence requires a mathematical description that accounts for variation in multiple variables simultaneously.At a fixed point on the water...
01:17Standing Waves
Sometimes waves do not seem to move; rather, they just vibrate in place. Unmoving waves can be seen on the surface of a glass of milk kept in a refrigerator, which is one example of standing waves. Vibrations from the refrigerator motor create waves on the milk that oscillate up and down but do not seem to move across the surface. These waves are formed or created by the superposition of two or more identical moving waves in opposite directions. The waves move through each other, with their...
