Risk assessment methods of water supply system in terms of reliability and operation cost
Over the past years in Central and Eastern Europe, including Poland, it can be observed that there has been a considerable decrease in water consumption. This leads to high operational costs due to underutilised capacity of existing drinking water treatment plants (DWTP) or distribution systems. Under these conditions providing rational management of DWTP requires technical, economical and reli...
متن کاملReliability of Operation of Water Resources Systems
The concept of reliability of a water resources system is examined from the point of view of hydrologic design, within a model-based system framework. Four levels of design are distinguished and illustrated. Level I is the classical method of design by exceedence probability; level II consists in design by Gaussian probability of failure (or its complement, the reliability); level III is design...
متن کاملon the comparison of keyword and semantic-context methods of learning new vocabulary meaning
the rationale behind the present study is that particular learning strategies produce more effective results when applied together. the present study tried to investigate the efficiency of the semantic-context strategy alone with a technique called, keyword method. to clarify the point, the current study seeked to find answer to the following question: are the keyword and semantic-context metho...
15 صفحه اولCOMPARISON ABILITY OF GA AND DP METHODS FOR OPTIMIZATION OF RELEASED WATER FROM RESERVOIR DAM BASED ON PRODUCED DIFFERENT SCENARIOS BY MARKOV CHAIN METHOD
Planning for supply water demands (drinkable and irrigation water demands) is a necessary problem. For this purpose, three subjects must be considered (optimization of water supply systems such as volume of reservoir dams, optimization of released water from reservoir and prediction of next droughts). For optimization of volume of reservoir dams, yield model is applied. Reliability of yield mod...
متن کاملSpatial distribution of water supply reliability and critical links of water supply to crucial water consumers under an earthquake
Observations from past earthquakes, such as the 1906 San Francisco earthquake, the 1994 Northridge earthquake, and the 1995 Hyogoken-Nanbu (Kobe) earthquake, have clearly demonstrated that compromising water supply systems after an earthquake not only impairs fire fighting capacity, but also disrupts residential, commercial, and industrial activities, and threatens the economic well-being, secu...
