Although now over 100 years old, the classification of climate originally formulated by Wladimir Köppen and modified by his collaborators and successors, is still in widespread use. It is widely used in teaching school and undergraduate courses on climate. It is also still in regular use by researchers across a range of disciplines as a basis for climatic(More)
Papers published in Hydrology and Earth System Sciences Discussions are under open-access review for the journal Hydrology and Earth System Sciences Abstract Although now over 100 years old, the classification of climate originally formulated by Wladimir K ¨ oppen and modified by his collaborators and successors, is still in widespread use. It is widely(More)
Gedney et al. attribute an increase in the twentieth-century continental runoff to the suppression of plant transpiration by CO2-induced stomatal closure, by replicating a continental runoff data set. However, we have concerns about this data set and the methods used to construct it, in addition to those already raised, which we believe may undermine their(More)
EXTENDED ABSTRACT Hydroclimatic variability occurs over time scales ranging from seconds through to millennia. Fluctuations at certain time scales, like monthly, seasonal, annual, interannual and interdecadal, are particularly important for the sustainable management of land and water resources systems. Quantifying the proportion of variation in a(More)
L-moment ratio diagrams are increasingly being used in the literature for selecting a probability distribution function for regional frequency analysis. Two graphical methods are often used in the distribution selection process, the sample average and a line of best-fit through the sample L-moment ratios. Examples of homogeneous and heterogeneous regional(More)
EXTENDED ABSTRACT Disturbance of forested catchments by fire, logging, or other natural or human induced events that alter the evapotranspiration regime may be a substantial threat to domestic, environmental and industrial water supplies. While security of water supplies have always been of high importance in Australia, the recent long-lived drought,(More)
Annual and monthly streamflows for 729 rivers from a global data set are used to assess the adequacy of five techniques to estimate the relationship between reservoir capacity, target draft (or yield) and reliability of supply. The techniques examined are extended deficit analysis (EDA), behaviour analysis, sequent peak algorithm (SPA), Vogel and Stedinger(More)
