Stream load | All rock fragments and dissolved substances from rocks moved along in the stream water. | | Similar Terms |

Charge, or Load | 1 - Sediment carried by a water channel at a given cross section. Expressed as the weight of sediment per unit of time. 2 - See 6036 and 8204...... | | Similar Terms |

Wash load | Suspended material of very small size (generally clays and colloids) originating primarily from erosion on the land slopes of the drainage area and or existing in the bed itself to a negligible degree...... | | 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 |

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 |
2570 |
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 |
2572 |
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 |

Silt pressure, or Silt load | Pressure exerted by saturated silt deposited against upstream side of a water retaining structure. The horizontal component (Vs) of silt load is given by Rankine`s formula by neglecting friction ..... | | Similar Terms |

Bed load | 1 - Sand, silt, gravel, or soil and rock detritus carried by a stream on or immediately above its bed. The particles of this material have a density or grain size such as to preclude movement far above or for a long distance out of contact with the stream bed under natural conditions of flow. 2 - The quantity of silt, sand, gravel, or other detritu..... | | Similar Terms |

Bed material load | That part of the sediment load which consists of grain sizes represented in the bed. | | Similar Terms |
3115 |
Bed load function | The rates at which various discharges will transport the different grain sizes of the bed material in a given channel. | | Similar Terms |
3116 |
Bed load equation | The general relationship between bed load rate, flow condition, and composition of the bed material. | | Similar Terms |
3117 |
General movement of bed load | The stage of movement when all sediment sizes of the bed material are in motion and the movement is strong enough to develop bed configuration...... | | Similar Terms |

Contact load | The material rolling or sliding along the bed in substantially continuous contact with the bed. | | Similar Terms |
