Abstract | From April 10 to June 14, ablation rates of lee drifts behind 3.8-m-tall snow fences, having moderate bottom-gaps on level terrain, averaged about 1.0 cm/deg/day. Mean ablation rate was 11% greater for a fence having a 90-cm bottom-gap. Ablation rate averaged aboaut 5% more over the windward half of the lee drift as compared to the downwind half. This uniformity allows drift length, cross-sectional area, and potential melt rate to be predicted over the melt season.The Federal snow sampler overmeasured the density of melting drifts by about 10%. Although desity of drifted snow before melt varies with depth, melting snowdrifts have a uniform desity of about 600 kg/m3. |
