Hydraulic Fracturing in Earth Dams (Boreholes)
… fracturing in earth embankment dam cores and boreholes published by various authors have been outlined and compared in this investigation. An experimental study was conducted which reinforces the fact that hydraulic fracturing in boreholes is a tensile phenomenon.

Minor actinide waste disposal in deep geological boreholes
… minor actinide waste in deep geological boreholes using conventional oil/gas/geothermal drilling technology. The nature of minor actinide waste was considered, paying particular attention to nuclides whose decay energy and half lives were of relative significance to the minor actinide …

Optimization of deep boreholes for disposal of high-level nuclear waste
This work advances the concept of deep borehole disposal (DBD), where spent nuclear fuel (SNF) is isolated at depths of several km in basement rock. Improvements to the engineered components of the DBD concept (e.g., plug, canister, and fill materials) are presented. Reference site parameters and …

HYDROGEOLOGIC PROPERTY ESTIMATION IN PLATE BOUNDARY OBSERVATORY BOREHOLES USING TIDAL RESPONSE ANALYSIS
… properties and time variations for 17 boreholes within NSF Earthscope’s Plate Boundary Observatory (PBO) network along the San Andreas fault and Cascadia subduction zone. Permeability and hydraulic diffusivity determinations range from 6.4_10-16 – 8.4_10-14 m2 and 1_10-4 – 9_10-1 m2s-1, …

Hydraulic properties of subglacial sediment determined from the mechanical response of water-filled boreholes
… is to be understood. Freezing of water-filled boreholes drives water into the subglacial bed and the associated pressure effects give information about subglacial hydraulic properties. A numerical model describing the mechanical response of an unconnected borehole and the bed beneath it to this …

Detailed studies of the Callovian and Oxfordian microplankton from the Warboys and Warlingham boreholes
… (Upper Jurassic) of the Warboys and Warlingham Boreholes, based on 118 samples. Chapter one sets out the aim of the study as being (i) to evaluate the significance of microplankton assemblages in biostratigraphic correlation, (ii) establish a zonation scheme for the interval studied and …

An evaluation of the feasibility of disposal of nuclear waste in very deep boreholes
Deep boreholes, 3 to 5 km into igneous rock, such as granite, are evaluated for next- generation repository use in the disposal of spent nuclear fuel and other high level waste. The primary focus is on the stability and solubility of waste species, waste forms, and canister materials in saline, …

Towards a model for environmental assessment and management of boreholes in communal areas in Namibia
… to inform, guide and manage the provision of boreholes in communal areas in Namibia. The model has been designed to be cost effective, appropriate for its context and 'user-friendly'. Most importantly, the model aims to present a system which would promote principles of sustainability and, …

Effects of siting boreholes and septic tanks on groundwater quality in Saint Bonaventure Township of Lusaka District
… in Lusaka have allowed use of septic tanks and boreholes in the same area in some Townships. St. Bonaventure located about 7km from Town center to the south in Makeni is one of such areas. Lusaka City is built on a marble which is cut by a network of fissures that are open hollows or filled with …

Development of the Spectral-Analysis-of-Body-Waves (SABW) method for downhole seismic testing with boreholes or penetrometers
… study is to improve downhole seismic tests with boreholes, cone penetrometers or flat-plate dilatometers by developing a frequency-domain analysis method which overcomes many of the disadvantages of time-domain analyses. The frequency-domain method is called the Spectral-Analysis-of-Body-Waves …
