Extracted text: Fig .1: Side and top of view of the proposed dam 1. Provide preliminary dam design, A stable gravity dam cross-section must be designed in terms of sliding and overturning given that the coefficient of sheer resistance of the foundation soil is 0.75, and the tailwater level of water converted into the channel directly behind the dam is 0.5m. Assuming an uplift force variation with no information about drainage (as a straight line from 100% of the headwater pressure at the upstream face (heel) to 100% of the tailwater pressure at the downstream face (toe) applied over 100% of the base area) and assuming usual conditions only. 1.1 Provide a schematic diagram showing the forces imposed on the dam 1.2 Determine the horizontal and vertical forces imposed on the dam body. 1.3 Determine the dam weight needed to achieve a sliding factor of safety of 1.5 1.4 Determine the moments imposed at the dam toe. 1.5 Determine the dam weight needed to achieve an overtuning factor of safety of 2.
Extracted text: Scenario: As a Hydraulic Engineer you are required to design a dam to create a reservoir in Amman City, open channel and pumps to convey water from the reservoir to a downstream community, and a pipe network to distribute the water within the community. Based on the hydrology assessment of the watershed the dam height was set to 12 m above ground level, with a freeboard of 2m (water level in the dam is 10m), dam width of 60m, and downstream flow was set at 8.5 m'/s (see Fig.1 below). Your task as an engineer is to provide a water supply for a planned community. Your project will involve (as a minimum): 10 m 12 m Q-85 mys 60 m Top view Side view Fig 1: Side and top of view of the proposed dam
