Climate change can affect different drivers of flooding in low-lying coastal areas the world, challenging design and planning communities infrastructure. The concurrent occurrence multiple flood such as high river flows extreme sea levels aggravate impacts result catastrophic damages. In this study, individual compound effects riverine are investigated at Stephenville Crossing located coastal-e...

Uncertainties in calculated impacts of climate forecasts on future regional air quality are investigated using downscaled MM5 meteorological fields from the NASA GISS and MIT IGSM global models and the CMAQ model in 2050 in the continental US. Differences between three future scenarios: high-extreme, low-extreme and base case, are used for quantifying effects of climate uncertainty on regional ...

20 Twenty-first century projections of Atlantic climate change are downscaled to explore the 21 robustness of potential changes in hurricane activity. Multi-model ensembles using the 22 CMIP3/A1B (Late 21 st century) and CMIP5/RCP4.5 (Early and Late 21 st century) scenarios are 23 examined. Ten individual CMIP3 models are downscaled to assess the spread of results among 24 the CMIP3 (but not th...

The impacts of climate change are increasingly threatening the sustainability ecosystems around world. Pulangi River Basin (PRB) in Philippines is experiencing sedimentation beyond tolerable amount (11.2 tons/ha/yr) due to land conversion and effects change. Changes precipitation temperature likely further affect annual runoff sediment yield PRB. In this study, Soil Water Assessment Tool (SWAT)...

This study investigated the effects of climate change on the evapotranspiration amount and water balance in the Zayandeh-Rud river basin. Two important weather stations; Isfahan and Chelgerd stations, located in the East and West of the basin respectively, were selected for investigation in this study. The combination of 15 GCM models were created based on the weighting method and three pattern...

Climate change can strongly affect renewable energy production. The state of the art in projecting future generation has focused on using regional climate prediction. However, prediction is characterized by inherent uncertainty due to complexity models. This work provides a comprehensive study quantify impact uncertainties potential over five zones Europe. Thirteen scenarios, including global m...

Strategies to enhance local adaptation capacity are needed to mitigate climate change impacts and to maintain regional stability of food production. The objectives of this study were to simulate the climate change effects on phenology stages, potato production in the future and to explore the possibilities of employing planting dates and various varieties (Agria, Arinda and Santeh) as mitigatin...

over the past decades a number of approaches have been applied for forecasting mortality. in 1992, a new method for long-run forecast of the level and age pattern of mortality was published by lee and carter. this method was welcomed by many authors so it was extended through a wider class of generalized, parametric and nonlinear model. this model represents one of the most influential recent d...
