The lognormal, Gumbel, smemax, log-Boughton, loglogistic, Pearson-3 and log-Pearson-3 distributions are applied to the annual flood peaks series longer than 21 observations of 112 unregulated natural streams in 23 major basins in Turkey. The parameters of most of those distributions are estimated by the methods of: (a) moments; (b) maximum likelihood; and (c) probability weighted moments. A det...

A harvest contr...

This section of the study describes the modelling assumptions used, and the outputs from the highest level of harvesting modelled which is termed the high level of harvest. This scenario was developed specifically in response to the FSD requirement to assess the consequences of a level of harvest that approximated the estimated maximum annual volume of timber production. This level was intended...
