The spatial pattern of medium-term (a few months) dry aeolian dust accumulation in rocky deserts is predicted using shortterm deposition and erosion experiments in a wind tunnel. The predictions ape tested in a field experiment set up in the northern Negev Desert of Israel. The results show that superimposing wind tunnel deposition and erosion maps usually leads to correct predictions of medium-term dust accumulation. The predictions are somewhat less confident near the inflection lines of windward hillslopes, where small-scale irregularities in the local topography make it difficult to locate the exact position of the areas of little accumulation. Elsewhere in the topography predictions are good, and the method works satisfactorily.
