abstract in this research the thermal stratification of the water in the torogh dam basin and the resulted changes in its quality with respect to temperature, salinity and dissolved oxygen was investigated using the dynamic reservoir simulation model. the results indicated that in wet years such as 1998, when the average annual precipitation and the resulted inflows to the basin is higher than ...

Flows along the upper Qu’Appelle River are expected to increase in the future via increased discharge from Lake Diefenbaker to meet the demands of increased agricultural and industrial activity and population growth in southern Saskatchewan. This increased discharge and increased air temperature due to climate change are both expected to have an impact on the water quality of the river. The Wat...

Agri-environmental programs, such as the Environmental Quality Incentives Program, provide payments to livestock and crop producers to generate broadly defined environmental benefits and to help them comply with federal water quality regulations, such as those that require manure nutrients generated on large animal feeding operations to be spread on cropland at no greater than agronomic rates. ...

Despite broad interest in using payment for ecosystem services to promote changes in the use of natural capital, there are few expost assessments of impacts of payment for ecosystem services programs on ecosystem service provision, program cost, and changes in livelihoods resulting from program participation. In this paper, we evaluate the Paddy Land-to-Dry Land (PLDL) program in Beijing, China...

assessing the quality of groundwater is important to ensure the sustainablesafe use of these resources. however, describing the overall water quality condition isdifficult due to the spatial variability of multiple contaminants and the wide range ofindicators (chemical, physical and biological) that could be measured. therefore, in thiscase study, some water quality parameters including na, mg,...

Carbon monoxide (CO) is predicted to be the dominant carbon-bearing molecule in giant planet atmospheres, and, along with water, important for discerning oxygen and therefore carbon-to-oxygen ratio of these planets. The fundamental absorption mode CO has a broad double-branched structure composed many individual lines from 4.3 5.1 $\mathrm{\mu}$m, which can now spectroscopically measured JWST. ...

The hydrodynamic/water quality model is an important tool in water environment management. It used to gain a deeper understanding of physical, chemical, and biological processes develop models capable represent surface waters with realism. A hydrodynamic can give essential data sediment, noxious, eutrophication modelling. Models enable decision-makers select alternatives for management that are...
