Water conservation is needed to overcome the shortage of irrigation water through harvesting rainwater on rainfed land using small farm reservoir. Intensive agricultural activities cause a reduction in resources which disrupts hydrological functions (water quantity and quality). This study aims determine selected parameters for reservoir quality identify based standards according FAO (1994) PP ...

With the increasing application of Linked Open Data, assessing the quality of datasets by computing quality metrics becomes an issue of crucial importance. For large and evolving datasets, an exact, deterministic computation of the quality metrics is too time consuming or expensive. We employ probabilistic techniques such as Reservoir Sampling, Bloom Filters and Clustering Coefficient estimatio...

This paper presents a methodology to determine the effect of flow forecasting quality on the benefits of reservoir operation. The benefits are calculated in terms of the electricity generated, and the quality of the flow forecasting is defined in terms of lead time and accuracy of the forecasts. In order to determine such an effect, an optimiza5 tion model for reservoir operation was developed ...

satellite data have been used for temperature modeling both in urban areas and water. this paperstudies viability of aster satellite images that provide high spatial and spectral resolution to model watersurface temperature, as a fundamental water quality parameter. this study is focused on dez dam reservoirresiding in khuzestan province, south west of iran. after the image corrections required...

â understanding the flow behaviour in a gas well is crucial for future production strategies, obtaining bottomhole conditions from wellhead production data, analyzing production data and estimating reservoir properties. in this work, the pressure profile and flow regime are studied on four wells of a multi-well, multi-layer gas-condensate reservoir, producing at high rate. the wells are deviate...

fracture system in carbonate reservoirs is very complex. understanding the features of fractures such as dip, strike and the other parameters can help to distinguish the behaviour of reservoir in any exploration and production plan. image log is the best way to investigate feature planes like fracture and bedding. image log in one of drilled well #10x393 of bangestan reservoir in gachsaran oilf...

The quality and quantity of water available for both economic growth and life sustainability is one of the major challenges for the sustainable development in the 21st century. This challenge requires research focused on the monitoring of time changes in water properties in several spatial scales. Satellite remote sensing has been applied as an alternative for providing information on optically...

In many locations around the globe, large reservoir sustainability is threatened by land use change and direct pollution loading from the upstream watershed. However, the size and complexity of upstream basins makes the planning and implementation of watershed-scale pollution management a challenge. In this study, we established an evaluation system based on 17 factors, representing the potenti...

Aims. Evaluate the early and long term surgical and functional results of the ileal pouch-reservoir (IPAA) in patients with intractable ulcerative colitis. Material and Methods. Followup of 134 consecutive patients with W-or J-ileal pouch by diseases-specific and general health (SF-36) questionnaire. In the first 44 patients, early and late followup was performed. Results. Followup was performe...
