Embankment dam Name Name of institution Professor Course Date Introduction An embankment dam can be defined as a gigantic but artificial water barrier. It is classically created by the emplacement and compaction of a multifaceted semi-plastic mound of diverse compositions of sand, rock or and soil…
Some of the causes of embankment include embankment deformations under static loading, which occur due to volumetric changes, tangential and shear displacements within the embankment and groundwork materials. This study establishes that the volumetric changes are due to either a raise in the normal stresses on a soil constituent, which causes a decrease in void volume, or dilation of soil rudiments undergoing shear (INDRARATNA, & ASHOK, 2006). The riskiest event of an embankment dam is when it overtops beyond its spillways thus causing the ultimate failure. What is the purpose of upstream and downstream filters? Upstream can be defined a course away from the supply of power in a fluid system under the pretext of an embankment dam. In other words, downstream in a hydraulic structure is in the same bearing as the fluid is moving. To start with, the purpose of the downstream filters involves upgrading the dams intended to meet the safety standards. It is imperative to note that retrofitting stepped up spillways to the dam is the most recent and accepted method, where when the waters flows down a stepped spillways, the water surface changes from a smooth surface to a rough surface with visible white water (INTERNATIONAL COMMISSION ON LARGE DAMS, 1994). Designing of the stepped spillways, and stilling basins finds the knowledge of the beginning of the white water fundamental. ...
