river is normally found in an area of high ground. The river usually flows through a steep V-shaped valley. Most of the erosion that occurs in the upper course is vertical and as the river bed is eroded lower the valley becomes steeper. The river is narrow with a shallow channel. As discharge is calculated by measuring the cross sectional area of the channel multiplied by the velocity‚ the discharge is small. The river is mainly slow flowing as most of its energy is used overcoming the friction of the

As a result of this limited knowledge‚ there can be difficulties in communicating risks as well as knowledge of mitigation measures (Terpstra et al‚ 2006). The lack of perception research can lead to the limitation of risk communication due to the narrow understanding of the‚ fears and concerns of individual citizens and public groups (Bier‚ 2001). Botzen et al (2009) adds that risk perception of natural hazards can give insight to persons’ willingness to take precautionary measures as well as the

INTRODUCTION A natural disaster is a major adverse event resulting from natural processes of the Earth; examples include floods‚ severe weather‚volcanic eruptions‚ earthquakes‚ and other geologic processes. A natural disaster can cause loss of life or property damage‚ and typically leaves some economic damage in its wake‚ the severity of which depends on the affected population’s resilience‚ or ability to recover.[1] An adverse event will not rise to the level of a disaster if it occurs in
