ABSTRACT On March 9, 1982 oil from an unknown offshore source began to wash ashore near Port Bolivar, Texas. Beach cleanup was coordinated between the U.S. Fish and Wildlife Service, the U.S. Coast Guard, and local authorities. Oiled sand was removed from the beach and stockpiled for local use in road construction. Oiled lesser scaup (Aythya affinis) appeared on the beach almost as soon as the oil did. The Fish and Wildlife Service coordinated volunteer efforts at capturing and cleaning the scaup. A total of 37 birds were captured, with 19 brids being taken in one night outing. Oiled bird cleaning began on March 10 and was completed on March 12. Procedures followed those described by Williams.3 Five scaup were washed three times, 31 washed twice, and one washed once. Thirty-five scaup were released on March 15 and two on April 27. No birds died during cleaning and the survival rate of the released birds is estimated to be 89 to 97 percent. Three factors were responsible for this successful oiled bird cleanup: advance preparation in the stockpiling of supplies and the training of volunteers; the availability of an adequate cleanup station; and the cooperation of volunteers and government agencies.

Abstract Four cores from Kootenay Lake have been dated using 2l0Pb. These cores have also been analyzed for total Pb concentration specifically to compare the sediment record with the known history of lead-zinc mining around the lake. Two sorts of impact on the lake are recorded in the sediments. First, there is obvious contamination by Pb in which concentrations within cores parallel the regional “boom-and-bust” mining history. Second, the sedimentation rate appears to have been affected by damming of the inflowing rivers and probably also by logging and the associated road construction in the watersheds. Spatial variability within the lake sediments is evident: sedimentation rate is highest towards the north and south ends of the lake where river inflow is greatest; contamination by Pb is highest in the middle of the lake close to the major mining activities.

The work is devoted to the town-planning heritage of Livadia. For the first time, relying on the graphic design sources of the 1860s and the turn of the XIX - XX centuries, the history of the formation of the ensemble of the new and second after Oreanda imperial residence in the Crimea is revealed. The content and characteristics of the imperial private order in post-reform Russia are considered. The central place is occupied by the design of the ensemble, its functional structure and boundaries, the architectural and spatial development of the territories, the principles of planning and development the issues of park construction and the use of the naturallandscape.In the era of historicism and national romanticism, a new trend in the arrangement of the privatelife of Russian monarchs was the appeal to the examples and traditions of the Russian aristocratic manor. The estate of Livadia, with the established complex of a noble manor, was bought by Alexander II from the heirs of Count L.S. Pototsky and presented to the Empress Maria Alexandrovna. The subject of the study is the town-planning transformation aimed at adapting and further developing the ensemble in order to accommodate the royal famty, the court the retinue, and the extensive system of services.Livadia reconstruction can be divided into two stages. The first is connected with the most intensive transformations of the environment carried out in 1862-1866 undertheleadership of I.A. Monighetti. The architect proposed the concept of a dispersed system of resettlement and placement of new building complexes outside the front of the estate core - auxiliary household military and other services of the residence. An integral part of the plan was road construction and development of infrastructure along with new sections of territories within the boundaries ofland ownershipThe second stage of active construction in Livadia occurred in 1869 - the beginning of the 1880s, and it was mainty directed to social programs. It was the erection of the second church of the estate in the midst of settlement complexes for personnel of the residence services; school for 120 people, etc. The principles of park construction extended to each of the peripheral sections and complexes. The system of water supp^ along with the engineering and technical support service of the estate and surrounding settlements were created. Livadia resembled a city-residence and a city-garden.For the first time the general plans of Livadia that reveal the scale of architectural transformations during the period of possession of the royal family are published.

This article examines the history of road planning in the decades following the Second World War on the Navajo Nation. Federal highway planners and Navajo residents had conflicting ideas about the role of roads in the Nation's postwar development. The planners’ support for highways near uranium mines undermined efforts towards Navajo self-development and modernization. Federally planned and subsidized highways granted extractive industries control over large portions of the Nation. Those highways locked in a regime of environmental exploitation that caused severe and debilitating public health consequences for Navajo communities.

Abstract. The paper gives an overview of the history of evolution and mitigation of the Macesnik landslide in N Slovenia. It was triggered in 1989 above the Solčava village, but it enlarged with time. In 2005, the landslide has been threatening a few residential and farm houses, as well as the panoramic road, and it is only 1000 m away from the Savinja River and the village of Solčava. It is 2500 m long and up to more than 100 m wide with an estimated volume in excess of 2 million m3. Its depth is not constant: on average it is 10 to 15 m deep, but in the area of the toe, which is retained by a rock outcrop, it reaches the depth of 30 m. The unstable mass consists of water-saturated highly-weathered carboniferous formations. The presently active landslide lies within the fossil landslide which is up to 350 m wide and 50 m deep with the total volume estimated at 8 to 10 million m3. Since 2000, the landslide has been investigated by 36 boreholes, and 28 of them were equipped with inclinometer casings, which also serve as piezometers. Surface movements have been monitored geodetically in 20 cross sections. This helped to understand the causes and mechanics of the landslide. Therefore, landslide mitigation works were planned rather to reduce the landslide movement so that the resulting damages could be minimized. The construction of mitigation works was made difficult in the 1990s due to intensive landslide movements that could reach up to 50 cm/day with an average of 25 cm/day. Since 2001, surface drainage works in the form of open surface drains have mainly been completed around the circumference of the landslide as the first phase of the mitigation works and they are regularly maintained. As a final mitigation solution, plans have been made to build a combination of subsurface drainage works in the form of deep drains with retaining works in the form of concrete vertical shafts functioning as deep water wells to drain the landslide, and as dowels to stop the landslide movement starting from the slide plane towards its surface. Due to the length of the landslide and its longitudinal geometry it will be divided into several sections, and the mitigation works will be executed consecutively in phases. Such an approach proved effective in the 800 m long uppermost section of the landslide, where 3 parallel deep drain trenches (250 m long, 8 to 12 m deep) were executed in the autumn of 2003. The reduction of the movements in 2004 enabled the construction of two 5 m wide and 22 m deep reinforced concrete shafts, finished in early 2005. In Slovenia, this sort of support construction, known from road construction, was used for the first time for landslide mitigation. The monitoring results show that the landslide displacements have been drastically reduced to less than 1 cm/day. As a part of the stepwise mitigation of the Macesnik landslide, further reinforced concrete shafts are to be constructed in the middle section of the landslide to support the road crossing the landslide. At the landslide toe, a support construction is planned to prevent further landslide advancement, and its type is still to be defined during the procedure of adopting a detailed plan of national importance for the Macesnik landslide.
