A POLLUTION MODEL OF THE CHARLES RIVER BASIN

this study was conducted to determine taxonomic and zoogeographic features of fishes from the kor and helleh river basins in southwestern iran. the specimens were collected from 2004 to 2007. twenty four species belonging to 20 genera, 9 families, and 6 orders from the kor river basin and 21 species belonging to 19 genera, 8 families, and 6 orders from helleh basin were identified. ichthyofauna...

Regional initial water rights is a crucial part of initial water rights and clarification of it is an essential method to improve the efficiency of water use. It also promotes sustainable use of valuable water resources. Consequently, under new circumstances of China’s most stringent water resources management, with water quantity and quality control, we propose a new perspective for a coupled ...

Two continuous gas assessment units (AUs) are present in the Late Triassic (Carnian) onshore rift basins of North Carolina and south-central Virginia. The source rocks are freshwater lacustrine shales that were deposited near the paleo-equator after the onset of Pangea rifting. These two rift basins, the Deep River basin wholly contained within North Carolina’s border, and the Dan River-Danvill...

In this present study, Remote Sensing (RS) and Geographical Information System (GIS) techniques are used to update drainage and surface water bodies to evaluate linear, relief and aerial morphometric parameters and to prioritize the watersheds of the Markandeya River Sub-Basin (MRSB), located in Belgaum district of Karnataka state,India. The Markandeya River Sub-Basin has sub-dendritic to dendr...

We describe two new species of pebblesnails (Lithoglyphidae: Fluminicola) from southwest Oregon based on morphologic and mitochondrial DNA (COI, cytB) evidence. Fluminicola umpquaensissp. n., which had been traditionally identified as F. virens prior to the recent restriction of the latter to the lower Columbia River drainage, lives in lotic habitats in the Umpqua River basin. This species is r...

This paper describes a spatially-explicit agent-based model of river basin land use and water management. The model is being implemented within a project aimed at investigating ways of synthesising stakeholder priorities, taking the EU Water Framework Directive as a case study. There are many human activities that take place in a river basin and can alter the ecological status of the water, and...

Precipitation extremes play a key role in flooding risks over the Huaihe River Basin, which is important to understand their hydrological impacts. Based on observed daily precipitation and streamflow data from 1958 to 2009, eight precipitation indices and three streamflow indices were calculated for the study of hydrological impacts of precipitation extremes. The results indicate that the wet c...
