OBS

Basin Head is a shallow coastal lagoon located on the eastern tip of Prince Edward Island, near the town of Souris. The lagoon is surrounded by both agricultural land and an extensive sand dune system. Approximately 5 kilometres long, Basin Head is a unique coastal environment that the community, conservation organizations, and both levels of government are working towards protecting for generations to come.

OBS

Basin Head est une lagune située à l'extrémité est de l'Île-du-Prince-Édouard, près de la ville de Souris. La lagune est entourée de terres agricoles et d'un vaste système dunaire. Longue de 5 kilomètres seulement, elle constitue un habitat côtier exceptionnel que les organisations de conservation et les deux paliers de gouvernement tentent de protéger au profit des générations à venir.

Subject field(s)
  • Waste Management
  • Nuclear Waste Materials
CONT

The simplest form of engineered trench, or shallow land burial, relies mainly on the properties of the excavated overburden and the geohydrologic properties of the site for containment. The intent is to ensure that the travel time of radionuclides from the waste to the human environment via groundwater is long compared to the nuclide half lives. Travel time is long because of low hydraulic gradients, soils of low water permeability and high contaminant adsorption, and lengthy pathways across exclusion zones.

CONT

Illustration of a shallow land burial facility (engineered trench). ... Figure 9 outlines the engineered trench option. In this option, the major characteristics are that: . wastes are placed below grade (in suitable hydrogeological conditions) in trenches having a specially prepared bottom that incorporates a drainage system; . there is an earthen cover over the wastes that easily can incorporate additional engineered barriers; . structural stability is not provided by the disposal facility; and . for structural stability, voids between the waste containers are filled with sans or earthen materials - bulk wastes may be compacted.

CONT

Shallow-land burial in trenches was the original low-level waste disposal practice at the beginning of the nuclear era. The method originally consisted in emplacing the wastes in trenches dug into the ground at depths ranging from 3 to 6 m and covering the emplaced wastes with about 1 m of soil.

CONT

Burial trenches without additional engineered barriers can be used provided that radionuclides will migrate into groundwater beneath the site at an acceptable rate.

OBS

As used in this context, the word "engineered" refers to the fact that features and materials have been designed or selected to accomplish certain functions. In shallow land burial the materials are usually natural rather than man-made.

OBS

In 1951 John L. Rich was the first to propose that the depositional settings of sediment accumulation on the shelf, slope, and bottom be(1) unda for shallow water overlying the shelf,(2) clino for the deeper water overlying the slope, and(3) fondo for the deepest water covering the bottom of the basin(Friedman(2001). Rich suggested the terms(1) undaform for any surface underlying an unda environment;(2) clinoform for any surface underlying a clino environment;(3) fondoform for any surface underlying a fondo environment.... Following this approach Mitchum(1977) proposed that clinoform surface be used for the sloping depositional surface that is commonly associated with strata prograding into deep water.

OBS

Rich chose three Greek words as general ones for the three critical environments. These are (1) unda for the shallow water overlying the shelf, (2) clino for the deeper water overlying the slope, and (3) fondo for the deepest water covering the bottom of the basin.

DEF

A subaqueous landform, such as the continental slope of the ocean or the foreset bed of a delta.

CONT

A clinoform is a seaward-dipping surface of a prograding sediment body that consists of a gently dipping topset, a steeply dipping foreset, and a gently dipping bottomset. The topset consists of fluvial and subaqueous environments coupled at the shoreline. Clinoforms are ubiquitous in modern depositional systems and are the fundamental constructional units of stratigraphic sequences.

Rich was the first to propose that the depositional settings of sediment accumulation on the shelf, slope, and bottom be(1) unda for shallow water overlying the shelf,(2) clino for the deeper water overlying the slope, and(3) fondo for the deepest water covering the bottom of the basin(Friedman(2001).
