I want to place some figures at the left or right side of my book resulting into a reduced column width for the text. So I am using wrapfigure environment with number of narrow lines of 40. By this way the figure covers the whole page. However, I want the figure to be place at the bottom and the white space above the figure. How can a realize this?
\begin{wrapfigure}[40]{O}{0.4\textwidth}
\includegraphics[width=0.4\textwidth]{Fig3-Givonis-bioclimaticchart}
\caption[Givoni's bioclimatic chart for four representative climate zones of Nepal]
{Givoni's bioclimatic chart for four representative climate zones of Nepal}
\label{fig:Fig3-Givonis-bioclimaticchart}
\end{wrapfigure}
