Physical yield limit, or Potential yield | The greatest rate of artificial withdrawal from an aquifer that can be maintained throughout the foreseeable future without regard to cost. Equal therefore to the present recharge, or that anticipated in the foreseeable future, less the unrecoverable natural discharge...... | | Similar Terms |

Gravity method (two-dimensional method of analysis) | A method for stress analysis of gravity dams assuming the structure of the dam to be composed of vertical cantilever elements that act independently of each other while the vertical stress varies linearly...... | | Similar Terms |
2577 |
Cracked cantilever analysis | In thin arch dams the applied radial loads tend to produce tension in the cantilevers. Since ordinary concrete is usually not assumed to have a tensile strength more than a specified value (say, 20 kg/cm2) and when this specified value of stress is exceeded all the cantilevers in tension may be assumed to be cracked to the point of zero stress so t..... | | Similar Terms |

Mechanically induced water seal | Water seal formed by mechanical means such as (i) by installing an air pump to suck out air from the siphon (ii) by installing a flexible steel plate at the crest and projecting into the siphon duct (illustrated)...... | | Similar Terms |

Environmental impact analysis | A more‑or‑less formal consideration of the interaction of a proposed human activity with environmental elements that might be affected by the activity. Includes a determination of the probable effect of the activity on social and economic conditions. Assessment of impact generally involves two major elements ‑ a quantitative measure of magni..... | | Similar Terms |

Risk assessment/analysis | A methodology to determine the nature and extent of risk by analysing potential hazards and evaluating existing conditions of vulnerability that could pose a potential threat or harm to people, property, livelihoods and the environment on which they depend. ..... | | Similar Terms |

Flood frequency analysis | The estimation of the frequency of occurrence of floods at a site. Flood frequency analysis generally consists of attempting to fit a probability distribution to flood discharge data and generalise the results for use at sites with no flood data. Many techniques have been proposed and are in use...... | | Similar Terms |
7972 |
Dam break analysis | The analysis of the flood flows resulting from postulated conditions of partial or total failure of a water storage dam. Such analyses are particularly important where a significant population would be put at risk by such a failure, and would define conditions for flood warning criteria, as well as for safety factor requirements in dam design or st..... | | Similar Terms |
