KRISFLOW Hydrogeological Computer System

KRISFLOW HCS is designed for determination of the depth of groundwater, depending on various factors, in particular agricultural practices and drainage system regime. The created system associated with the geographic information system allows systematizing the information characterizing the long-term regime of flooding, predicting the dynamics of groundwater in accordance with natural, agricultural, and technological factors and justifying the solutions on reconstruction and optimization of the drainage network.

Adapting the model to the hydrogeological conditions of areas with large planar dimensions needs coordination and introduction of a large number of input data of different nature, presented in the form of tables and maps. For irrigation systems, for example, KRISFLOW requires data for areas and rules of irrigation, location of channels of different purposes and water loss for filtration, location of boreholes, data on the pumping volumes from them, monitoring data, etc. Data entry is greatly simplified granting the user interface and application of geographic information system (GIS).

Information System has sophisticated user interface, where the input data are entered via screen forms with visual control in GIS. In addition, binding of the models and GIS with their ability to process data and spatial analysis functions significantly enhances data analysis, display of simulation results, creation of thematic maps, etc.


The developed software allows automated dis-playing of simu-lation results on the map in the form of absolute ground water surface levels or thematic maps according to the depth of occurrence of the groundwater, as well as graphic and attribute information for the model. In addition, the information system has convenient means of setting the object of investigation, which allows quick adapting it to the conditions of different areas requiring actions to prevent flooding and control of influence of the harmful effects of ground water.

Using the information system as a whole or its individual components allows:

Making a long-term forecast of flooding, using the data of area of irrigation, average rainfall, irrigation rate, location of drainage wells;
Optimizing the network of observation wells;
• Working out various schemes of reconstruction of irrigation and drainage system on the model;
• Implementing the model calculation of the situation development with groundwater in the region;
Reducing the negative impact associated with the infiltration losses of irrigation water (elution of mineral elements from soil, secondary salinization of soils, impoundment, removal of nitrogen and phosphorus with drain water).

The information system was used to simulate the dynamics of groundwater and optimize drainage at Krasnoznamenskaya irrigation system, located in the territory Golopristanskiy district, Kherson region. The simulation of flooding up to 2015 was made.

The developed methodology and information system comply with globally accepted approaches to solving of problems associated with harmful effects of water.

The system elements were used to simulate the influence of tailing ponds of the Poltava ore-dressing and processing enterprise on ground water and removal of contamination in the Dnieper (in conjunction with the Canadian firm SNC-LAVALIN within the framework of Assessment of Groundwater Pollution with Industrial and Municipal Wastes project) etc.
