There is typically a distinction between short waves, which are waves with periods less than approximately 20 s, and long waves or long period oscillations, which are oscillations with periods between 20-30 s and 40 min. Water-level oscillations with periods or recurrence intervals larger than around 1 hour, such as [[tide|astronomical tide]] and [[storm surge]], are referred to as water-level variations. The short waves are wind waves and swell, whereas long waves are divided into [[surf beat]]s, harbour resonance, [[seiche]] and [[tsunami]]s. Natural waves can be viewed as a wave field consisting of a large number of single wave components each characterised by a [[wave height]], a [[wave period]] and a propagation direction. Wave fields with many different [[wave period]]s and heights are called irregular.

Human activities and nature conservation conflicts at the Kenyan coastline

Figure 1: Map of SE Africa.

The Kenyan coastline is approximately 500 km long, with a well developed fringing reef system except where major rivers (Tana and Athi Sabaki) discharge into the Indian Ocean (Hamilton and Brakel, 1984).The coastal zone environment and its resources in the western Indian Ocean(WIO) region countries: Kenya, Tanzania, Mozambique, Seychelles, Mauritius and Comoros play an important role in the economy of the people.

Population growth, loss of social and community identity, lack of resources, hunger and poverty are the central problems of Kenyan coastal area. The development process has meant that effective and sustainable management is no longer feasible, despite the availability of resources.
