Hydrometry

Hydrometrie (from Greek: hydros = water; Metron = measure ) is called the quantitative (quantitative ) detection of the water cycle. The Hydrometrie collects data from surface water, groundwater and precipitation, evaluates them and represents them

Only the continuous monitoring of water level and discharge ( for surface waters ) can detect long-term changes and determine the probability of large floods. Water level and discharge are measured by so-called levels. This is calculated using the statistics return periods that make up the characteristics of the particular body of water.

• Precipitation: volume per time, volume in mm, it is considered 1 mm = 1 l/m2
• Rivers: the water level, level, as Kote in meters above the sea. About one -level outflow relationship to the associated outflow is determined as a volume per unit time, m3 / s
• Groundwater: the water level, level as Kote in meters above sea

Depending on requirements, additional parameters such as temperature, conductivity, pH value, and others are collected.

The data is now mostly covered with electronic / electromechanical sensors and stored in a data logger and processed.

Through the use of contemporary communication tools, the measured values ​​can be transmitted rapidly and made ​​available to the general public.

Possible applications of the data:

• Enable the sustainable use and management of water resources
• Basic data for research
• Valuation and tax base for flood protection projects and measures
• Determination of residual amounts of water
• Basis for the regulation of water
• Etc.
