Volume computation is based on following:Pre dredge survey bathymetric data (reference)Post dredge survey bathymetric dataChannel design ( to calculate Cut and Fill)Once you have all the prerequisite data, you can use and hydrography processing software for comparing pro and post survey data to determine volume dredged or need to be dredged.
The results of the Loch Ness Bathymetric and Seismic Survey in 1991 found the maximum depth to be 745ft (226.96m). It was recorded 1km south of Urquhart Castle.

You can find the results of a customer satisfaction survey you have taken part in by contacting the company which provided the survey. Sometimes you can also find the results posted online.
The last step of taking a survey typically involves submitting your responses. This can be done by clicking a "Submit" or "Finish" button provided at the end of the survey. Make sure to review your answers before submitting to ensure accuracy.
The answer depends on what information the survey collects.

when there are errors in sampling design, such as biases in selecting participants or a non-representative sample, which can lead to inaccurate results.
Random sampling is a procedure that can help ensure participants in a survey are representative of a larger population. This involves selecting individuals from the population at random, giving each individual an equal chance of being chosen for the survey. Random sampling helps reduce bias and allows for generalization of survey results to the larger population.

Data analysis must be used to understand the results of a survey. Otherwise, the data collected by the survey would remain a jumbled collection of data.
