Utilizing the newest sonar technology allows river sampling teams to greatly enhance their capability to view a sampler track during deployment. This essential tool allows the sampler operator to visualize in real-time, the ascending and descending location of the sampler throughout the water column. The active sonar screen information provides a clear side perspective of not only the position of the moving sampler, but upstream and downstream moving bed forms. During high water events which produce higher velocities, and increased depths, sampler cable payouts tend to differ from actual water depths due to drag on the tether cables and samplers. This unwanted effect can misinform operators of the sampler’s actual depth. Using Live Scope sonar technology greatly enhances an operator’s capability to deploy a sampler to precise depths and therefore avoiding unwanted bed contact or hazards.
