AbstractWater shortages have led the Libyan authorities to investigate and then develop fossil water resources in the remote south of the country. Initially the development was in situ, but in 1979 it was decided to embark on an ambitious water carrier to bring water from the south-east and the south-west of the country to the settled areas of the northern coast. It is concluded in the paper that Libya will have developed sufficient water by the end of the century to secure its urban and industrial needs. It will also have the option to allocate a similar, or an even greater, quantity to agriculture than at present achieved, but it is argued that such agricultural allocations will not be economically viable.

Water resources are under unprecedented strain. The combined effects of population growth, climate change, and rural industrialization have led to greater demand for an increasingly scarce resource. Ensuring that communities have adequate access to water—an essential requirement for community health and prosperity—requires finegrained management policies based on real-time in situ data, both environmental and hydrological. To address this requirement at the state level, we have developed the South Carolina Digital Watershed, an end-to-end system for monitoring water resources. In this paper, we describe the design and implementation of the core system components: (i) in situ sensing hardware, (ii) collection and uplink facilities, (iii) data streaming middleware, and (iv) back-end repository and presentation services. We conclude by discussing key organizational and technical challenges encountered during the development process.

Borobudur temple has been famously known as one of the Indonesian heritage masterpiece. Various aspects of it had been studied thoroughly since the beginning of 20th century A.D. Those studies tended to be monumental centric, giving less attention to the cultural context of the temple and its surroundings. Settlement in the nearby places is one of the topics which not have been studied much yet; leaving a big question about how the settlement supported continuity of many activities in the temple, or even the other way around; how the temple affected the settlement. There is only a few data about old settlement found in situ in Borobudur site, only abundance of pottery sherds. The analysis applied on to the potteries find during the 2012 excavation had given some information about the old settlement in Borobodur site. The old settlement predicted as resided in the south west area, in the back side of the monument.

The mistletoe flora of southern Western Australia was studied over a 30-year period with a particular emphasis on distributions, host relationships and fire. The study area encompassed Western Australia south of ~26° S. It included all the South-west Botanical Province and southern components of the Eremaean Botanical Province, with the northern boundary corresponding with bioregional boundaries. Vegetation ranges from wet and dry sclerophyll forest through woodlands and heaths to deserts. The mistletoe flora comprises 21 taxa, 19 in the Loranthaceae and two in the Santalaceae. They infect 153 species in 25 genera and 15 families. The Fabaceae provides hosts to more taxa than any other family; however, the genus with most host species, Eucalyptus (Myrtaceae), supports only two mistletoe species, one of which barely enters the study area. Melaleuca (also Myrtaceae) is host to seven species. The number of mistletoe species per bioregion ranges from 0 to 18, with 12 species in the seven bioregions of the South-west Botanical Province and 20 in the six bioregions of Eremaean Botanical Province that are within the study area. In both provinces, diversity is lower in coastal areas and higher in more arid, inland areas. Most mistletoe habitats in the study area are fire-prone. One species is probably capable of resprouting whereas all other taxa are obligate seeders. With no means of in situ seed storage, post-fire recovery depends on seed importation. Fire is the most pervasive (but not the only) threatening process operating today. However, fire management in more populous agricultural and urban areas safeguards many populations in the South-west Province.

Through the kindness of Dr. Flett there has come into my hands an interesting boulder of nepheline-syenite belonging to Sir John Murray, dredged during the expedition of the Michael Sars(1) from the Atlantic Rise at a depth of 1,750 fathoms at a place about 150 miles south-west of the south-western corner of Ireland (Station 95 of the Reports of the Michael Sars Expedition). The slices examined were slides Nos. F 2092 to F 2095 from the Geological Survey Collection and two belonging to Dr. Peach. It is a boulder of remarkable freshness, and so entirely unlike any other specimen as yet recorded from the floor of the Atlantic that the question of its origin is of some interest. The fact that no other fragments of the same type were obtained in this dredging militates against the view that it is part of a mass in situ on the sea-bottom. Its companions from the same station, and in fact all the specimens collected by the Michael Sars, have been recognized by Dr. Peach and Dr. Flett as similar to rocks occurring commonly in Ireland, the North-West Highlands, and the Southern Uplands of Scotland, and not one among them is closely related to the nepheline-syenite. Bocks of Irish types have also been described by Professor Cole and Mr. Crook (2) as a result of earlier dredgings of the Atlantic floor, and again no specimen has been found remotely resembling the subject of this paper.

A method has been suggested for geotechnical monitoring of tectonic fault rock mass of the south-west wall in Qajaran open-pit mine by applying the pseudo-static method of CPTu (Cone Penetration Test with in-situ pore water pressure measurements) which gives an opportunity to define the root parameters of soils such as: pore water pressure, unit weight, drained and undrained shear strength. The versatile in-situ CPTu methods allow to profile simultaneously the geotechnical properties of each soil strata with permanent penetrating speed, and also while using the SCPTu (Seismic Cone Penetration Test with in-situ pore water pressure measurements) method, as well as determine horizontal and shear seismic wave velocities from the given geomechanical environment. At that, it also becomes possible to pull out independently intact samples from tectonic-fault-soils for future laboratory testing. Two different approaches for geomechanical proposition of the south-west wall stability of Qajaran open-pit mine based on the limit equilibrium theory and outputs from the proposed in-situ geotechnical seismic monitoring (SCPTu) have been analysed. The difference of the results from the two analyzed approaches (USA vs ESA) was about 8 to 10% in estimating the slope stability. Based on the analyzed results of the stability of the south-west wall of Qajaran open-pit mine, it is recommended to apply undrained strength analysis for undrained tectonic-fault soils (USA – Undrained Strength Analysis) instead of the effective drained strength analysis (ESA – Effective Strength Analysis) for drained rocks by taking into account the developed excess pore water pressure when saturated clayey soils sheared in undrained conditions.
