“…The tailings produced on the PSV, which are chemically active, organic, non-geological and concentered with water contaminants, e.g., heavy metal sedimentations, should be transported to a harbor to eliminate the enormous environmental effects in the sea. This kind of tailings should undergo storage; dehydration by evaporation; consolidation by gravity, and the reinforcement materials, e.g., cement to form the tailings paste through tailings dam disposal [39].…”

Abstract:Deep sea mining tailings disposal is a new environmental challenge related to water pollution, mineral crust waste handling, and ocean biology. The objective of this paper is to propose a new tailings disposal procedure for the deep sea mining industry. Through comparisons of the tailings disposal methods which exist in on-land mining and the coastal mining fields, a new tailings disposal procedure, i.e., the submarine-backfill-dam-reuse (SBDR) tailings disposal procedure, is proposed. It combines deep sea submarine tailings disposal, backfill disposal, tailings dam disposal, and tailings reuse disposal for the deep sea mining industry. Then, the analytic network process (ANP) method is utilized to evaluate the performances of different tailings disposal methods. The evaluation results of the ANP show that the new proposed tailings disposal procedure is the most suitable for the deep sea mining industry.

“…Bu 2-B özdirenç verilerini değerlendirme yazılımında, ölçülen saha verileri ile model verileri arasındaki farkları en küçüklemek için, hem düzgünlük-kısıtlı en küçük kareler ters çözümü hem de robust ters çözüm yöntemleri kullanılmaktadır [13]. Robust ters çözüm yöntemi, yeraltı materyallerindeki elektrik iletkenlikler arasında büyük farklar olduğunda, yeraltı modelindeki keskin sınırları ortaya çıkarmada daha yeteneklidir [5]. Bu sebepten dolayı, bu çalışmadaki tüm ERI verilerinin ters çözümünde bu yöntem kullanılmıştır.…”

“…Images of subsurface bulk electrical resistivity can therefore be used to help assess geologic units that may be more likely to conduct seepage through foundation or embankment materials, or to map regions of increased saturation. Numerous resistivity studies have focused on both internal erosion detection (Cho and Yeom, 2007;Kim et al, 2007;Sjö dahl et al, 2005Sjö dahl et al, , 2008 as well as identification of seepage pathways associated with dam foundation materials (Abu-Zeid, 1994;Di and Wang, 2010;Panthulu et al, 2001).…”

“…These tasks are accomplished through the use of two complementary electrical geophysical methods, self-potentials (SP) and direct-current (DC) electrical resistivity, which have been commonly used in dam seepage and other integrated hydrogeologic studies (Berube, 2007;Ogilvy, 1970a, 1970b;Bolève et al, 2009;Corwin, 2007;Dahlin et al, 2008;Ogilvy et al, 1969;Panthulu et al, 2001;Sheffer, 2007;Sjö dahl et al, 2005Sjö dahl et al, , 2008Titov et al, 2005). SP is a passive method that is primarily sensitive to active subsurface groundwater flow and seepage, whereas DC resistivity is an activesource method that can provide information about changes in subsurface lithology and groundwater saturation.…”

Self-potential and direct current resistivity surveys are carried out at the Hidden Dam site in Raymond, California to assess present-day seepage patterns and better understand the hydrogeologic mechanisms that likely influence seepage. Numerical modeling is utilized in conjunction with the geophysical measurements to predict variably-saturated flow through typical two-dimensional dam cross-sections as a function of reservoir elevation. Several different flow scenarios are investigated based on the known hydrogeology, as well as information about typical subsurface structures gained from the resistivity survey. The flow models are also used to simulate the bulk electrical resistivity in the subsurface under varying saturation conditions, as well as the self-potential response using petrophysical relationships and electrokinetic coupling equations.The self-potential survey consists of 512 measurements on the downstream area of the dam, and corroborates known seepage areas on the northwest side of the dam. Two directcurrent resistivity profiles, each approximately 2,500 ft (762 m) long, indicate a broad sediment channel under the northwest side of the dam, which may be a significant seepage pathway through the foundation. A focusing of seepage in low-topography areas downstream of the dam is confirmed from the numerical flow simulations, which is also consistent with past observations. Little evidence of seepage is identified from the self-potential data on the southeast side of the dam, also consistent with historical records, though one possible area of focused seepage is identified near the outlet works. Integration of the geophysical surveys, numerical modeling, and observation well data provides a framework for better understanding seepage at the site through a combined hydrogeophysical approach.
