In dam construction stages when an earth embankment has retained a reservoir with constant water surface elevation for long time, seepage conditions within the will be reach steady state. If it is necessary to drain quickly, pore-water pressures in may remain relatively high while stabling effect of reservoir's weight along upstream (U/S) side removed. This process referring as "Rapid Drawdown"...

Design, construction, as well reliable and safe operation of earthen hydraulic structures (earth dams) in the Republic Uzbekistan, located a seismically hazardous zone, require constant improvement load calculation methods, required by building codes, including loads (static - gravity, hydrostatic) temporary dynamic (seismic). The current normative method does not take into account non-one-dime...

With the majority of United States Department Agriculture-Natural Resources Conservation Service (USDA-NRCS)-sponsored earthen dams exceeding their planned service life, seepage is a concern since it common failure mechanism among as whole. Seepage occurs when water penetrates hydraulic barrier to create open pathways, channels, or piping leading internal erosion stability issues due increased ...
