Lonar lake is a inland saline crater lake of only one of its kind in Asia, which depicts unique limnology and biodiversity. Studies were undertaken to evaluate its unique ecosystem. Wetlands of this lake have archaeological significance. Due to its importance to the humans, studies were carried out with regard to its water quality in terms of physico-chemical characteristics, heavy metal concen...

Variations in a lake area constitute an important indicator of the modifications of the lake hydrology. This paper explores the inter-annual variations of the Poyang Lake area during the dry seasons occurringwithin the 1961 to 2010 period and further quantifies the severity of dryness recently endured during the 2000s. A physically based hydrodynamic model of Poyang Lake established the relatio...

the zarivar lake a freshwater lake in west of kurdistan province is home for large number of native plant and animal species therefore water quality and health of the lake are vital for conservation of these species. the present study aimed at evaluation of the zarivar lake using nsf- wqi as an indicator of water quality. wqi is a suitable tool to examine and classify spatial and temporal varia...

[1] The Great Salt Lake is a terminal lake whose level is determined by the balance between inflows and outflows. We examine the causes for multimodality in the distributions of lake level and hence volume and area that have previously been examined from a system dynamics perspective. We focus on the role of bathymetry in the dynamics of this system and show that some of the modes that are obse...

Stable isotopic compositions of lake water provide additional information on hydrological, meteorological and paleoclimate processes. In this study, lake water isotopic compositions were measured for more than three years in Lake Taihu, a large and shallow lake in southern China, to investigate the isotopic spatial and seasonal variations. The results indicated that (1) the whole-lake mean δ(2)...

polycyclic aromatic hydrocarbons (pahs) in the priority controlling list of us epa weresystematically evaluated in surface sediments in dianchi lake and its estuaries. total pah concentrations(σpahs) varied from 210 to 11,070 ng/g dry weight (d.w.) in dianchi lake, and from 230 to 12,271 ng/g d.w.in the estuaries. σpahs in sediments from caohai section were higher than those from waihai section...

in the last decade, the water level of urmia lake has experienced a dramatically drop. although the causes of this lose have been investigated, the significance of groundwater supplies had not been concerned so much. in the present research, groundwater resources around the lake were explored as its water supplier. the number of wells and groundwater withdrawal has been increased because of cul...

A study was carried out on the occurrence of chitinolytic bacteria inhabiting surface water, water above the sediment and bottom sediments of lakes: Jeziorak, Jeziorak Maty and Tynwald. The greatest amounts of them were found in demersal water and in bottom sediment surface stratum. However, the percentage share of chitinolytic bacteria proved greater in deep water (9.35%) than in bottom sedime...

Interesting landforms created by an ancient network of earthworks are shown, using Google satellite imagery enhanced by an image processing. This network covers a large part of the land near the Titicaca Lake. Satellite images clearly display the slopes of hills criss-crossed with terrace walls and the surfaces of the plains covered with raised fields, indicating that this was once a highly pro...

CanaddBritish Columbia Mineral Development Agreement, this area was selected for more detailed analysis than presently available. During the 1986 field season fieldwork was centred on the Cowichan Lake area (Figures 3-9-1 and 3-9-21, Access in the area is provided by an extensive network of logging roads in various states of upkeep. Roadcuts provide most ofthe exposure for mapping; rock units a...
