vodonosnim

The term "vodonosnim" is a Russian word that translates roughly to "water-bearing" or "aquiferous." It is primarily used in geological and hydrological contexts to describe geological formations, such as rock layers or soil deposits, that are capable of holding and transmitting groundwater. These formations are crucial for understanding and managing underground water resources.

A vodonosnim layer is essentially an aquifer, a saturated zone beneath the Earth's surface. The porosity of the material within the vodonosnim determines how much water it can store, while its permeability dictates how easily water can flow through it. Common materials that form vodonosnim include sandstones, gravels, limestones, and fractured rocks. Conversely, impermeable layers, known as aquicludes or aquitards, act as barriers to groundwater flow and are not considered vodonosnim.

The identification and characterization of vodonosnim are essential for various purposes, including the location of wells for water supply, the assessment of groundwater contamination risks, and the management of subsurface drainage. Hydrogeologists study the extent, thickness, and properties of vodonosnim to model groundwater movement and predict its availability. Understanding these water-bearing layers is fundamental to sustainable water resource management.
