abstract irregular extraction from agricultural wells around parishan lake, moreover fall of groundwater surface and water salty, would affect the level of lake water and move lake water into wells. in this study we have evaluated the externalities of extraction from agricultural wells around the lake. therefore feedback effect is considered between agricultural activity around the lake and lev...

Introduction The City of Austin’s Watershed Protection Department strives to protect the water quality in Austin area watersheds. Austin creeks have been monitored for years through the Environmental The Austin Lake Index (ALI) was designed to provide a yearly assessment of the environmental integrity of Lake Austin, Lady Bird Lake, and Lake Long. Sub-indices used to compute the ALI include rep...

in this study some thermodynamic parameters including freezing point, boiling point and the vapor pressure of urmia lake salt water were investigated as some important environmentally monitored physicochemical properties of urmia lake. in this regard salt concentration is chiefly responsible for the modification of the thermodynamic properties of urmia lake water which affects its overall envir...

Relative to their scarcity, large, deep lakes support a large proportion of the world's freshwater species. This biodiversity is threatened by human development and is in need of conservation. Direct comparison of biodiversity is the basis of biological monitoring for conservation but is difficult to conduct between large, insular ecosystems. The objective of our study was to conduct such a com...

ACCESS AND PHY SIOGRAPIHY Large lakes at elevations ranging from 656 to 844 re t res provide boat access to about 30 per cent of the map area. These lakes are most easily reached by floatplane or hslicopter, both stationed in Atlin some 40 kilometres to the east. During high water (earl) July through to late Septenber) Tagish Lake can also he reached from Atlin by powerbolt via the Atlin River....
