Changes in climate, waterlogging hazards and regional floods are more prominent present context. The paper reviews potential of flood hazard dense urban areas, using GIS-based 1-D hydrodynamic model (MIKE URBAN). major factor contributing to the recent decades is climatic variability thus long-term variations precipitation drainage system an area were evaluated. MIKE URBAN (1-D) can be used com...

drought is a normal, recurring feature of climate phenomena; it may occur virtually in all climatic regions. the effects of drought accumulate slowly and its impacts are spread over a larger geographical area than other natural hazards. drought is a natural hazard originating from a deficiency of precipitation that result in a water shortage for some activities or some groups and is often assoc...

The Indonesian island of Sulawesi harbors a highly endemic and diverse fauna sparking fascination since long before Wallace's contemplation of biogeographical patterns in the region. Allopatric diversification driven by geological or climatic processes has been identified as the main mechanism shaping present faunal distribution on the island. There is both consensus and conflict among range pa...

Paleoclimatic time series are often unevenly spaced in time, making it difficult to obtain an accurate estimate of their red-noise spectrum. A Fortran 90 program (REDFIT) is presented that overcomes this problem by fitting a first-order autoregressive (AR1) process, being characteristic for many climatic processes, directly to unevenly spaced time series. Hence, interpolation in the time domain...

The aim of the study was to compare potential danger for human health caused by pollution in both underground and surface water sources with fungicide pydiflumetofen herbicides amicarbazone bicyclopyrone a wide range soil-climatic conditions. Three methods were used: determination integral hazard vector (R); predicting negative impact pesticides on population groundwater contamination index (IG...

For the last two decades, climatically based interpretations have been the major focus in evolutionary studies of dryland alluvial fans. Climatic hypotheses to explain the development of alluvial fans in southern Death Valley, however, do not fare well when they are assessed with criteria used by philosophers of science. First and foremost, dating techniques do not have the chronometric precisi...

Despite considerable interest in recent years on species distribution modeling and phylogenetic niche conservatism, little is known about the way in which climatic niches change over evolutionary time. This knowledge is of major importance to understand the mechanisms underlying limits of species distributions, as well as to infer how different lineages might be affected by anthropogenic climat...
