Why are environmental assessments essential?
Environmental assessments provide meteorological, hydraulic, and sediment transport information. The data may include wave action and current velocity, the degree of sedimentation, siltation and erosion, and the effects of wind, waves and weather. In the last few decades, environmental impact assessments (EIAs) have also become an essential part of site investigations. Careful study of the flora and fauna of a region such as sensitive seagrass or corals and the repercussions of disturbing these by maritime construction have become a crucial element in project planning. What are gravity waves? Gravity waves are divided into “sea” waves, which are located in a wave-generating area of the sea, and “swell” which occurs when the waves are no longer in the wave- generating area nor influenced by significant winds. Sea waves are steeper than swells and shorter in time length. Collecting wave data is complex and the most often recommended method is using devices that measure pressure, acoustic
