Research on leakage hazards of embankments based on 3D electrical resistivity tomography technology
GrađevinarLeakage is a common issue in reservoirs; however, accurately detecting its location and seepage diameter can be challenging owing to complex geological conditions.

The effect of isolating the core of earthen dams on their permeability [PDF]
MATEC Web of ConferencesSeepage via embankment dams is a crucial factor in the engineering and safety of dams. In order to provide a barrier against water movement, embankment dams are usually built using materials like soil, rock, or a combination of both that have been ...

Repeated Pleistocene Permafrost Episodes in the Western Pannonian Basin
Permafrost and Periglacial Processes, EarlyView.ABSTRACT Concerning the study of past periglacial processes, the Pannonian Basin is a key area as it contains the southernmost frost polygons found in Central Europe. The presence or absence of permafrost is still, however, a matter of debate, and data on the timing of frost action are also scarce.

Seepage Behavior of Earth Dams Considering Rainfall Effects
Advances in Civil Engineering, 2018 More than 60% of annual rainfall in Korea is concentrated during the monsoon season from June to August because of the climate characteristics of East Asia. In general, reservoir water levels sharply rise during this period and rock-fill dams are exposed

Restoring Lateral Connectivity to Anthropogenic Riverscapes: Six Lessons From Stage Zero
River Research and Applications, EarlyView.ABSTRACT Centuries of river modification, particularly straightening and incision, have severely reduced lateral connectivity between rivers and their floodplains. As a result, Stage 0 riverscapes, characterised by high lateral connectivity (e.g., anastomosing or wetland riverscapes), are now rare in anthropogenic landscapes.

Effect of Different Core Slopes and Filters on Seepage for Horan Dam, Iraq
مجلة النهرين للعلوم الهندسيةA dam failure results in losses in terms of economy and infrastructure, in addition to the loss of many lives and assets. Inadequate seepage control procedures are typically the cause of seepage failure in earth-fill dams.

Наука и техника, 2016 A methodology for determination of seismic accelerations in earth dams has been developed within the framework of seismic resistance wave theory. In this case we take into account an influence of the dam foundation and seismic wave emission into it.

River Research and Applications, EarlyView.ABSTRACT As ecosystem engineers, beavers (Castor canadensis) modify river corridor form through dam building. When beavers are removed from a river corridor, their unmaintained dams wash out, altering the stream's hydrologic regime. The assumption that beaver dams increase floodplain connectivity is frequently presumed but has not been directly ...
