| Abstract | Limnology is the study of geological, physical, chemical and biological events that occur in
impoundments of inland surface water. There is very little information available on the
limnology of tropical reservoirs because most of the knowledge we have is based on
temperate cases. There is a need to fill in gaps regarding tropical limnology because
remarkable changes in water impoundments' behavior and thus in water quality patterns can
occur with respect to climate differences. For instance eutrophication, one of the major issues
in water quality management, is more likely to occur under tropical climates where seasonal
variation in temperature and solar radiation are minimal. This study will help guide the
research activities of the Company Lyonnaise-des-Eaux ASTRAN (Asian-Pacific Technology
and Research Network).
This thesis consists of a literature review about temperate lakes and reservoirs' behaviors
throughout a year and a description of key physico-chemical processes and cycles. The
principal differences in physical and chemical processes between tropical and temperate lakes
and reservoirs have been described. As Lyonnaise-des-Eaux ASTRAN currently conduct
destratification experiments on reservoirs in Malaysia to improve the water quality in their
reservoirs, the results for one case study have been discussed in this report. Throughout the
thesis work, gaps in our knowledge concerning tropical reservoirs' behavior relative to
temperate reservoirs' behavior were identified. These gaps are therefore listed and discussed
based upon their significance to water quality and eutrophication processes. Finally, future
research is suggested whose steps are prioritized according to the order of importance of these
gaps. |
