Wave Action

DOE-STD-1022-94

5.3.8 Wave Action

A. For sites located near bodies of water and in regions exposed to extreme winds, wind data shall be evaluated

to assess the wave action. Should this hazard exist, water depths, fetch characteristics, and local topographic

data between the site and large bodies of water shall be collected and evaluated.

5.3.9 Landslide and Volcano Created Natural Hydrological Consequences

A. Land sliding into a river can dam the river and pose a flooding hazard upstream within the impoundment area

or downstream in the event of overtopping of the dam. Tectonic uplift can have a similar damming effect.

Volcanic eruption debris can create natural dams in narrow valleys and potential flood hazards. Volcanic

eruption may also be causes of mudflows, rapid sedimentation in river, and rapid snowmelt, thus, to create

potential flood hazards. Stability of slopes whose failures may cause this hazard shall be investigated. For

regions with potential volcanic activity, topographic data shall be collected to indicate the likely locations of

valley damming which could impact the site.

5.3.10 Flood Runoff/Drainage

A. Intense precipitation or snow melt may create local ponding or overland flooding when the soil infiltration

capacity is exceeded. In addition, drainage capacity may be exceeded creating additional flooding.

B. The data to be collected are the local topographic characteristics of drainage areas including depressions,

terrain slope, nature of soil vegetation or Manning's coefficients, and soil infiltration indices.

C. Data characteristics on precipitation and snowfall are provided in Section 52.3.

5.3.11 Ground Water Hydrology

A. Intense precipitation or snow melt and infiltration can cause ground water to rise and eventually to flood sites.

For sites with shallow ground water tables, data on regional and local aquifers shall be collected, including

formations and sources of the aquifers, local well log records, and drainage capacity.

B. Over pumping, reduced recharge and droughts can cause significant declines in ground water levels. This can

lead to land subsidence and well failure. For sites that use ground water for production, cooling, or human

consumption, or may be subject to land subsidence, record shall be kept of ground water level trends on a

quarterly (minimum) basis. The water-level data should be adequate to document any long-term safety or

environmental effects of ground water withdrawal.

5.4 GEOLOGY AND SEISMOLOGY

A. The seismic-related hazards include site earthquake ground shaking, tectonic site deformation (fault rupture

and associated tectonic surface deformation), ground failure induced by ground shaking including liquefaction,

differential compaction and land sliding, and earthquake-induced flooding. Other geological hazards to be

addressed include non-tectonic site deformation and volcanic hazards.
