Hydrography Clause Samples
The Hydrography clause defines the requirements and standards for surveying and mapping bodies of water within a project. It typically outlines the methods, equipment, and accuracy levels expected for collecting data on water depths, underwater features, and related characteristics. This clause ensures that all hydrographic information is gathered consistently and reliably, supporting safe navigation, construction planning, or environmental assessment, and ultimately helps prevent errors or disputes arising from inaccurate or incomplete waterway data.
Hydrography. The applied science which deals with the measurement and description of the physical features of oceans, seas, coastal areas, lakes and rivers, as well as with the prediction of their change over time, for the primary purpose of safety of navigation and in support of all other marine activities.
Hydrography. Observations during the JBSS 2016, 2017 and 2019 and assessment of historical data indicated an impact of the climate change in the Black Sea region. Temperatures in the so- Cold Intermediate L (CIL) have overwhelmingly exceeded 8 °С isotherm in Western and Central regions since 2009. The , in 2017. In contrast to 2017, both in 2016 and 2019 there was no CIL in "classical"definition as a layer bound by the 8 oC isotherm. The minimum temperature in the CIL in 2016, 2017 and 2019 was 8.28 ± 0.026, 7.62 ± 0.028 and 8.4 ± 0.1oC, respectively. The spatial and temporal variability of the position of upper border of the hydrogen sulphide zone in the deep part of the Black Sea is primarily determined by synoptic and seasonal variations of the hydrological structure of the sea waters. At the end of summer 2019 the upper border of the hydrogen sulphide zone in the Western and Central regions of the Black Sea fluctuated near the depth of 70 m. It went down to 135 m in Eastern region and to 150 m in South-Eastern part of the Black Sea. The upper boundary of hydrogen sulphide layervaried from σt =15,4 to σt =16,0 in the central part of the sea in 2017. This is
