Water Environment Monitoring at Lake Biwa and Fluctuations in Water Level

Age of Lake Malawi (nyasa) and Water Level Fluctuations

Lake Malawi (Nyasa) is one of the few deep-water long-lived lakes that presently exist on earth. It lies in an uncompensated tectonic graben, controlled by differential vertical movements between the rift basin who subsides and the rift shoulders who are uplifted. Active tectonics is the major factor controlling the development and persistence ofthose deep lakes. For Lake Malawi (Nyasa), climat...

WATER-LEVEL FLUCTUATIONS Ecological effects of water-level fluctuations in lakes: an urgent issue

Water-level fluctuations (WLF) affect the ecological processes and patterns of lakes in several ways. Aquatic habitats and feeding or breeding grounds are gained or lost, as light, climate and wave impacts change to mention only a few phenomena. While the phenomenon of WLF has been studied in many rivers (better known as flood pulse, Junk & Wantzen, 2004) and environmental flows (Bunn et al., 2...

Effects of Caspian Sea water level fluctuations on existing drains

This study is an attempt to develop an integrated methodology to predict the impact of the Caspian Sea on flooding using Geographic Information Systems (GIS) and hydrodynamic modeling. A rise in the sea level might lead to major flooding events, and have a severe impact on the spatial development of cities and regions. The feasibility of simulating a flood event along a drain channel is evaluat...

Least Squares Techniques for Extracting Water Level Fluctuations in the Persian Gulf and Oman Sea

Extracting the main cyclic fluctuations from sea level changes of the Persian Gulf and Oman Sea is vital for understanding the behavior of tides and isolating non-tidal impacts such as those related to climate and changes in the ocean-sea circulations. This study compares two spectral analysis methods including: Least Squares Spectral Analysis (LSSA) and Least Squares Harmonic Estimation (LSHE)...
