As I said in a comment, the accents package is your friend for this kind of problems:

$\accentset{\mathrm{h}}{\nabla}$

or maybe, as @campa suggested with \mathtt:

Using overset command:

\documentclass[a4paper,12pt]{article}
\usepackage{mathtools,amssymb}

\begin{document} [\overset{\mathtt{h}}{\nabla} ] \end{document}
