Impassable roads, poorly maintained railways, bankrupt airways, congested towns, and inefficient ports - are there hyperlinks among those matters and shortage of monetary growth in constructing nations? Inland waterways, ports, railways, roads, air and concrete delivery are all mentioned and illustrated with examples of fine and undesirable perform. the writer explains how shipping can in simple terms be potent if timing, place and know-how are selected conscientiously and if judgements are within the arms of the fitting events.

Example text

For the Developing Country there is the additional advantage that where there are waterways their transport capacity can often be increased substantially at low cost in comparison with other modes. This will be of particular significance where there is the potential for moving large volumes of bulk goods. It must always have been the case that wherever people could see the possibility of floating objects, water was used for transport. The methods adopted to achieve this end were as ingenious as they were varied (Hornell, 1946) and not surprisingly reflected local availability of materials.

IMPROVED RIVER NAVIGATION It will be apparent from the above discussion that there is considerable scope for improving one or other or indeed several of the physical characteristics of rivers. It is well for planners to keep in mind the complex relationship between the different parameters and the possible knock-on effects of modifying any one of them. For example, velocity, channel form and sediment transport are closely related. Few of the rivers used for navigation have not been improved in some way (Hadfield, 1986) and a river such as the Rhine is now more artificial than it is natural.

This may be reflected in congestion, delay, accidents, loss of time in transit, deterioration of the system and increased cost. While few if any transport networks are devoid of stress points it is probably the case that in many Developing Countries they are the norm rather than the exception and examples will be identified in later sections of this book. An essential aspect of transport planning is the identification of potential stress points well in advance so that action can be taken. With these general considerations in mind attention will now be directed to the specific modes of transport with particular emphasis on their technical characteristics, organisation and relationship to the broader issues of spatial organisation and development outlined above.
