Saturated sediment discharge | When the required materials are available in the bed to generate transportation capacity, the sediment materials that pass over the bed are stated to have reached the saturation level...... | | Similar Terms |

Bedload movement law | The classical laws of sediment transportation which help determine the transportation capacity of a river bed, or the sediment discharge at steady level. In other circumstances, the actual sediment discharge differs from the value of saturated sediment discharge. The bedload movement law is to specify that difference...... | | Similar Terms |

State of sediment discharge motion | State of a bed in which the erosive forces generated by the flow are equal to forces that withstand the erosion, deriving from the substratum. This state is characterized by a balance between the shear stress on the wall and the critical stress...... | | Similar Terms |

Trial load method | A three-dimensional method of dam analysis in which the dam is assumed to be made up of two or more systems of elements; for arch dams - vertical cantilever elements and horizontal arch elements; and for gravity dams - vertical cantilever element, horizontal beam elements and a twisted structure system of vertical and horizontal elements. Each syst..... | | Similar Terms |

Amplified trial load method | For arch dams it is an assumption that the water load is divided between the arch and cantilever elements, that the division may or may not be constant from abutment to abutment for each horizontal element and that the true division of load is the one which causes equal arch and cantilever deflections in all arches and cantilevers instead of at the..... | | Similar Terms |
2571 |
Abridged trial load method, or Simplified trial load method | Used for arch dam preliminary design work by using tables and curves for determining deflections of arches. Modified assumptions are made with regard to the foundation in this analysis which neglect (i) differences in elasticity of rock and concrete, (ii) the angle that the plane of the abutment makes with a vertical plane and (iii) certain seconda..... | | Similar Terms |

Trial load twist method (for gravity dams) | It is based on the assumption that the water load is divided between a structural system made up of vertical and horizontal elements with each system occupying the entire volume of the dam. For ungrouted joints there are two systems, the cantilever structure and the twisted structure. The grouted joints have three systems, the cantilever structure,..... | | Similar Terms |
