A landslide is a type of ‘mass wasting’ or down slope movement of soil and/or rock under. Note: The physical capacity of a pipeline is based on many factors such as the products being carried, direction of flow, pipeline pumping capacity, and maintenance work or other pressure restrictions. I typically estimate the EGL slope from the terrain slope in the area where the flow is expected to be most concentrated. 2,344; 5; 4 years, 9 months ago. The energy grade line should always slope downhill. Given two integer points (x1, y1) and (x2, y2). Nearshore slope, defined as the cross-shore gradient of the subaqueous profile, is an important input parameter which affects hydrodynamic and morphological coastal processes. This usually occurs from either. Anonymous.
