Book Description
Both forest harvest and cloud-seeding are believed to enhance late spring runoff in snow-dominated areas. This study used a water balance model and a field experiment to investigate the linkage between late-season snowmelt and streamflow in the mid-elevation snow zone of California's Central Sierra Nevada. The field experiment was designed to simulate the hydrologic effects of cutting small forest openings. The simulated snowmelt also created a statistically significantly lag in the soil moisture drying curves between the treated and the control plots. Tensiometer and soil moisture block data indicated that this difference persisted for at least 4-6 weeks in most locations. A bromide tracer was added to the simulated snowmelt. Less than one percent of the tracer left the catchment as surface flow in the summer following the experiment. The highest bromide concentrations were observed during high runoff events in the following winter. Suction lysimeters indicated that the initial movement of the tracer was largely consistent with a simple advection equation. Declining hydraulic conductivity due to evapotranspiration and gravitational drainage was the most important factor limiting the downslope movement of the simulated snowmelt. The porous bedrock in the experimental catchment makes it difficult to extrapolate to other sites. Nevertheless, the results suggest that cutting small forest openings to capture snow and delay melt will prove ineffective. Delayed or increased snowmelt can enhance late spring and early summer streamflow, but it is unlikely to increase late summer streamflow in the mid-elevation snow zone of the Central Sierra Nevada.--Adapted from abstract.
