Review:
Coasts are under considerable threat from the twin problems
of human coastal migration and potential change due to climate.
add to this that they are one of the most high energy environments
and you can see that there's considerable potential for change
- not all of it positive. This slim text looks at some of the
key aspects of coasts with the aim of giving the reader a base
from which to study these areas in greater detail. We start
with a brief overview of coasts from the vexed question of what
and where the are (not as simple as it seems in legal terms)
to some of the terminology used in coastal geography. The next
stage is to provide a description of the main coastal types
in the world. Although it can be argued that each beach is unique
in reality there are three main variants. The first, wave-dominated,
is the subject of chapter two. Waves and wave formations start
the chapter which then proceeds through erosional landforms
and ecology. This is followed by barrier beaches and sand dunes
i.e. depositional features. Chapter three looks at tidal coasts
with much the same format. Tides and tidal processes are highlighted
followed by key tide related features - estuaries, slat marshes
and mangroves. Chapter four continues with river-dominated coasts
which comprise chiefly deltas and their related formations and
ecology. Chapter five tackles the issue of sea level change
but from a geomorphological rather than pollution angle. Finally,
there's discussion on the main issues affecting beaches globally
and what can be done to moderate our impact. A
conclusion and glossary complete the text.
Overall,
this is avery useful text. Although it is not a large text it
puts a great deal of key information to the reader in a concise
and precise way. All main aspects are mentioned from processes
to coastal patterns and ecology. The chapter on management highlights
the pressure coasts are under and allows the reader to be aware
of some of the damage currently being caused. Having already
road-tested this text on senior students and getting a very
positive response one can conclude with confidence that this
text hits the spot and provides the beginner with an excellent
introduction.
