and Agriculture (NIFA) and Natural Resource Conservation Service (NRCS) to evaluate the effects of agricultural conservation practices on spatial patterns and trends in water quality at the watershed scale. In some projects, participants also investigated how social and economic factors influence implementation and maintenance of practices. The 13 projects were conducted from 2004 to 2011 as pa...
learning-oriented assessment seeks to emphasise that a fundamental purpose of assessment should be to promote learning. it mirrors formative assessment and assessment for learning processes. it can be defined as actions undertaken by teachers and / or students, which provide feedback for the improvement of teaching and learning. it also contrasts with equally important measurement-focused appro...
This study was conducted over seven villages near Darbandikhan district including (2) wells and (5) springs. It covers more than 60 km, to assess the suitability of ground water quality for drinking purpose using water quality index through investigating of different wells and springs; this technique is very useful tool for quick assessment for any water system. This was done by subjecting the ...
Remote sensing techniques play increasingly important role over recent decades in both problems of global climate change and frequent deterioration of the status of aquatic ecology, driven by the ever-increasing needs of growing populations for drinking water, polluted by overland runoff from point and non-point sources, as well as fish and other seafood (Pozdnyakov et al., 2005).

b a ckground: eco-faunistic studies are inevitable step in environmental researches. aquatic organisms like caddisflies are known as biological indicators for water quality assessment and water resource management. they have special role for energy flow in the freshwater habitats as food web and food chain among aquatic creatures. methods: in addition to an extensive literature revi...
We assess water quality and the status of water bodies with numerous variables, both abiotic and biotic. Up to date, few water quality assessment and ecoremediation measures took the surface water – groundwater ecotone (i.e. the hyporheic zone) into consideration. We developed a new index based on hyporheic copepod fauna. The copepod biodiversity in the hyporheic of 26 Slovenian rivers, belongi...
