Engineering-hydrometeorologic survey ensure complex studies of hydrometeorologic conditions of a construction area (region, site, track) and forecast of probable changes of these conditions as a result of reaction with the designed objects with the aim to acquire necessary and adequate data and materials for valid project decision-making.

The survey include:

• determination of capabilities to satisfy demands in water and organization of different water uses;
• choice of location areas for a construction site (track) and its engineering protection against adverse hydrometeorologic impact;
• drafting of a general territory plan;
• choice of engineering constructions, determination of their main parameters and construction organization;
• determination of constructions’ exploitation conditions;
• impact assessment of construction objects on the aerial and water environment and drafting of nature protection measures.

The following points are subject to studying in the process of engineering-hydrometeorologic survey:

• hydrologic regime   (of rivers, lakes, swamps, creeks, temporary water flows, seaside and shelf areas);
• climate conditions and particular meteorological features;
• dangerous hydrometeorological processes;
• anthropogenic changes of hydrologic and climate conditions or their particular characteristics;

Scope of works:

• collection, analysis and generalization of hydrometeorologic and mapping data of an area;
• reconnaissance of engineering survey area;
• observation of characteristics of a hydrologic regime of water objects and meteorological elements;
• study of dangerous hydrometeorologic processes;
• study of soil frost penetration and snow cover characteristics (for land);
• cameral data processing with determination of estimated hydrologic and (or) meteorological characteristics.
