Description:

Zone of aeration of soil is one of the most important and most complete parts of the hydrological cycle. Water storage in the zone of aeration is a big part of the Earth freshwater storage. Temporal course of soil water content in the zone of aeration can be determined by monitoring or mathematical modelling. We offer measuring and computational methods for determining basic hydrophysical, physical, transport, and regime characteristics of soil.

Inovation:

In-situ methods for measuring the saturated hydraulic conductivity of soil matrix (disc permeameter) and soil with macropores (Guelph permeameter) were improved. Laboratory equipment for measuring the retention curves was also improved. Mathematical model for computing the regime characteristics and water storage of soils was developed.

Application:

Diagnosis of the soil water regime and determination of water storage in the zone of aeration for agriculture and forest ecosystems to the purpose of optimal formation and exploitation of water storage.

State:

The staff of the Inbstitute of Hydrology has considerable experience in regionalisation of the hydrophysical characteristics of soils to the purpose of preparation of input data for mathematical models, in soil water storage evaluation, and in making diagnose of soil water regime.

Cooperation:

Service in obtaining of basic hydrophysical characteristics of soils, in monitoring of the soil water storage, and in computation of the moisture profiles in the zone of aeration. Making the expert’s accounts in the field of water management and agriculture.

Description:

Both agricultural and forest soils are vital for the biological activity and production. They are pivot for water transport and chemicals movement. Anthropogenic activities (channel regulations, water reservoirs, roads, etc.) influence the water movement in the soils and result in water storage changes in such regions. The measuring methods are offered for the monitoring of the soil moisture, groundwater tables, and hydrophysical parameters of the soils in regions with anthropogenic influences.

Inovation:

The neutron probe is in operation for soil moisture measurements, and methods for assessment of physical and hydrophysical properties of the soils are available.

Application:

Soil water regime diagnostics and estimation of the water storage in the zone of aeration in agricultural and forest ecosystems for water structures impact assessment. A method was developed and tested for statistical and analytical data processing and production of the final information on temporal and spatial variability of the soil water storage.

State:

The staff of the Institute of Hydrology SAS is experienced in soil moisture monitoring in area of the Gabčíkovo water structure, measurement of the hydrophysical parameters of the soils, preparation of input data to mathematical models, in soil water storage assessment, and in diagnostics of the soil water regime. The database processing of the results is offered which is very suitable for water storage assessment and its graphical interpretation.

Cooperation:

Services in obtaining of basic hydrophysical parameters of the soils, in soil moisture monitoring and soil water storage estimation. Elaboration of the appraisals and expertises in water and soil management on agreement basis.

Description:

• methodics for assessment of the surface water pollution impacts from non-point sources (nitrates, nitrites, phosphates,…);
• monitoring of the surface water pollution;
• creation of specialised databases of water quality and quantity;
• mathematical modelling of pollutant transport in the stream using the complex water quality models.

Application:

Surface water pollution assessment.

State:

The staff of the Institute of Hydrology SAS has developed a method for estimation of the surface water pollution by nitrates based on empirical relations. The personnel is experienced in application of the complex process model AGNPS, suitable for simulation of the extreme rainfall events and modelling of the runoff, sediment loads and transport of the pollutants (nutrients, pesticides, etc.) during these events.

Cooperation:

Development of the methodics, appraisals, expertises on agreement basis.
