dia and Bangladesh, the true cause was a combination of simultaneous high discharge
on large rivers, heavy rainfall, high groundwater tables, and so on (Hofer and Messerli
2006; see Chapter 11, this volume). Solid scientific evidence must be provided to avoid
potential hoaxes such as those that occurred in Asia.
GIS, remote sensing, and computer-enhanced field techniques and data sets should
continue to be developed and explored since they can help assess geomorphological
hazards. Web-based GIS structures that utilize remotely sensed data to monitor natural
hazards could be used to improve risk assessment in mountainous areas (Metternicht et
al. 2005). Not only will high-resolution DEMs integrated with GPS data, remotely sensed
data obtained from new sensors, digital landcover, soils, or other geologic information
will help predict the timing and location of hazards; these data sources will also im-
prove our understanding of mountain processes at previously unattainable spatial and
temporal scales (Butler and Walsh 1998; Walsh et al. 1998).
