Climate change and altered runoff in the semiarid portion of Mono Basin, Caifornia
Arid area ; California ; Climatic variation ; Global change ; Precipitation ; Runoff ; Semi-arid area ; United States ; Watershed
watersheds in the north-central portion of the Mono Basin is employed to simulate existing hydroclimatic processes and the alteration of these processes in response to climate change.
The purpose of this paper is to assess the hydroclimatic response of the semiarid portion of the Mono Basin to small changes in long-term mean temperature and precipitation. A climatic water budget model for the Cottonwood Creek and Bridgeport Creek
The purpose of this review is to examine the literature on developed coasts to identify the many ways that human activities alter coastal landforms, to reveal the pervasive nature of the conversion process and to demonstrate why human alterations

Measurements of active-layer thickness (ALT) at 7 locations on Calypsostranda, Svalbard (CALM Site P1), over 1986–2009, are used to estimate the influence of cloudiness, precipitation, air temperature, the Arctic Oscillation (AO) and the North
Atlantic Oscillation (NAO). No statistically significant correlations were determined between ALT and monthly precipitation and cloudiness at Barentsburg, Hornsund and Svalbard Airport stations. There were, however, very strong and highly significant
relationships with air temperatures in May and June. The influence of air temperature in May and June on ALT is indirect; it regulates the time of the melt of snow cover, which determines the duration of the ground-warming period. Using statistical relationships
between ALT and air temperature at Svalbard Airport, the time series of ALT at Calypsostranda is reconstructed from 1911 to 2010. It was also found that the AO and the NAO did not significantly affect ALT and air temperature on western Spitsbergen.
Possible impact of climatic change on forested landscapes in Central Europe: a review
Greenhouse impact on cold-climate ecosystems and landscapes

This paper briefly reviews and tentatively discusses 1) former climatic changes and their impact on forests, 2) the impact of climatic warming on the genetic constitution of forest trees, their physiological processes, and the possible alteration
Altitudinal alteration of the morphological systems in the Rio Checras basin of the Peruvian Andes
This article contains preliminary results of the field studies on the altitudinal alteration of geomorphological features and processes as a reflection of the Quaternary events. The huge stabilized landslides are the main feature of the slope
morphology. They were produced in a periglacial zone of the older Rio Blanco glaciation. The present glacial and cryonival systems were affected by the Punrun glaciation phase and postglacial climatic conditions. The valley bottoms and lowermost parts

The study is based on the assumption that the landscape borders are not perpetual lines, great nature transformation works like regulation of the river ways, protection against floods, the probable global climate change, or even the changes
of the persistent land use can alter them by decreasing or increasing the width of the transit zones, landscape ecotones. - (AM)

The understanding of North Atlantic climate and the dual processes of global warming and Gulf Stream action which affect it, is as uncertain today as in the early 2000s. This paper will show how fast our ideas on future global and North Atlantic

Human-induced climatic warming will have major impacts on permafrost, which presently underlies half of Canada's land mass. The extent of permafrost will diminish, accompanied by modifications of the land surface through thermokarst or mass wasting
. Streamflow regimes, sediment transport, coastal flooding and erosion will be affected. The magnitude of most components of the water balance will be altered.

Analysis of two clay-rich sandstone blocks from a temperate maritime, urban environment indicates that, although structural changes such as scaling and flaking affect only the outer 10-20 mm of stone, the zone of alteration extends well beyond
this to a depth of up to 60 mm. This zone of alteration coincides with chemical changes. Salt weathering is a threshold phenomenon where decay is manifest only when a stress/strength threshold is crossed. Consequently, in a structurally and mineralogically
