Diel fluctuations can comprise a significant portion of summer discharge in small to medium catchments. The source of these signals and the manner in which they are propagated to stream gauging sites is poorly understood. In this work, we analysed stream discharge from 15 subcatchments in Dry Creek, Idaho, Reynolds Creek, Idaho, and HJ Andrews, Oregon. We identified diel signals in summer low f...
Although the ecological dynamics of the alpine treeline ecotone are influenced by climate, it is an imperfect indicator of climate change. Mechanistic processes that shape the ecotone-seed rain, seed germination, seedling establishment and subsequent tree growth form, or, conversely tree dieback-depend on microsite patterns. Growth forms affect wind and snow, and so develop positive and negativ...
This paper presents a procedure for risk assessment hydrological disasters considering the threshold rainfall and environmental social criteria. A case study was carried out to test its feasibility in northern region of State São Paulo, Brazil. The advantage this is that it only uses data available on government institutions websites. For reason, other regions countries can easily adapt their r...
Suitability evaluation of urban construction land based on geo-environmental factors is the process of determining the fitness of a given tract of land for construction. This process involves a consideration of the geomorphology, geology, engineering geology, geological hazards, and other geological factors and is the basis of urban construction land planning and management. With the support of...
