Global Trends In Extreme Precipitation: Climate Models Versus Observations, Behzad Asadieh, Nir Y. Krakauer Jan 2015

Global Trends In Extreme Precipitation: Climate Models Versus Observations, Behzad Asadieh, Nir Y. Krakauer

Publications and Research

Precipitation events are expected to become substantially more intense under global warming, but few global comparisons of observations and climate model simulations are available to constrain predictions of future changes in precipitation extremes. We present a systematic global-scale comparison of changes in historical (1901–2010) annual-maximum daily precipitation between station observations (compiled in HadEX2) and the suite of global climate models contributing to the fifth phase of the Coupled Model Intercomparison Project (CMIP5). We use both parametric and non-parametric methods to quantify the strength of trends in extreme precipitation in observations and models, taking care to sample them spatially and temporally …


Cockatoo Sands In The Victoria Highway And Carlton Hill Areas, East Kimberley: Baseline Surface Water Quality, Don Bennett, Luke Donovan, Duncan Palmer Jan 2015

Cockatoo Sands In The Victoria Highway And Carlton Hill Areas, East Kimberley: Baseline Surface Water Quality, Don Bennett, Luke Donovan, Duncan Palmer

Resource management technical reports

Cockatoo Sands are recognised as potentially suitable for irrigated agriculture because they are generally well drained and not subject to waterlogging and inundation. These characteristics allow them to be cultivated and prepared for planting of various crops during the wet and dry seasons of northern Australia.


Nitrates In Karst Systems: Comparing Impacted Systems To A Relatively Unimpacted System, Julie C. Angel, Eric Wade Peterson Dec 2014

Nitrates In Karst Systems: Comparing Impacted Systems To A Relatively Unimpacted System, Julie C. Angel, Eric Wade Peterson

Eric Wade Peterson

Karst aquifers are highly susceptible to contamination because of the connection with surface water. Nitrate contamination is common; with most karst aquifers exhibiting some degree of impact. This work assesses the potential impacts of anthropogenic activities on the Horn Hollow Valley (HHV) in Carter County Kentucky. HHV is a karst aquifer system that appears to be minimally impacted by nitrate and chloride contamination. Sampling of the HHV area was conducted from June 2005 to November 2006. Nitrate as nitrogen (NO3-N) concentrations were between 0.13 to 1.54 mg/L; chloride concentrations ranged from 1.43 to 66.3 mg/L. Impact from anthropogenic sources are …
