How to influence the position of float environments like figure and table in LaTeX?

How I can set up the figure and tables to capture them in the next page. I have a problem in inserting the figure. I have referenced the figure but it has appeared before the specified place. I would like to revise the code in a way that figures appear in a next top part of page.

Code:

\begin{figure}
    \centering
        \includegraphics[width=0.9\textwidth]{C:/Thesis/Latex/thesis_1(1)/Figures/studyArea.jpg}
        \rule{35em}{0.3pt}
    \caption{The Grand St. Bernard wireless sensor network deployment (a) the coordinates of nodes according to the Swiss coordinate system (b) the distribution of the nodes in the study site \citep{r33}}
    \label{fig:study area}
\end{figure}

Answer 1

Specific to your problem - placing a float at the top of the next page - the afterpage package could be of help:

\documentclass{article}
\usepackage{afterpage,float,lipsum,graphicx}% http://ctan.org/pkg/{afterpage,float,lipsum,graphicx}
\begin{document}
See Figure~\ref{fig:label}. \lipsum[1-4]
\afterpage{%
  \begin{figure}[H]
    \centering
    \includegraphics[height=20pt,width=0.9\textwidth]{example-image-a}
    \caption{This is a caption}
    \label{fig:label}
  \end{figure}
}
\lipsum[5-10]
\end{document}

float provides the [H] float specifier. However, you might just as well have used a minipage environment and (say) caption's \captionof{figure}{...} for the caption.

Floats (figures and tables) can be forced to appear based on a set of parameters in the \begin{} ... \end{} float object. The syntax is \begin{figure}[x] where x can be h for placing "here"; t at the top of the (possibly curent) page; b at the bottom of the page; ! overrides all good parameter settings and forces an even harder "here". if you use the package float you also have H which is similar to !h. In addition there is a package placeins that provides a command \FloatBarrier which prevents floats from behin set after the command.
