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.
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.

Survey results refer to the data and feedback collected from a survey conducted among a group of individuals. These results typically include statistics, trends, and insights that summarize the responses to the survey questions. Survey results are used to analyze opinions, behaviors, preferences, and other relevant information from the surveyed group.
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.
affect the results of the survey.
The time it takes to get results from a seismic survey can vary depending on the size and complexity of the survey. Generally, it can take anywhere from a few weeks to a few months to process and interpret the data collected during the survey.
The answer depends on what information the survey collects.
To prepare a survey report, first, organize the survey data collected. Then, analyze the data to identify trends and key insights. Next, summarize the findings, highlight important points, and provide recommendations based on the results. Finally, format the report clearly with charts or graphs as necessary and include an executive summary for a quick overview.
A sample survey is quicker and cheaper. If the survey is well designed then the results are likely to be close to their true values.
