The Soil Erosion Station


The Soil Erosion Station deals with applied studies in the field of water and soil preservation, conducted by researchers, engineers and technical and administrative workers. The station’s activity spans more than 50 years, and the experience gained is reflected in its current unique applied scientific work.

The unit’s output includes: research reports, publications, scientific papers, general reports, lectures, guided tours and field application specifications.

Areas of work and development at the Soil Erosion Station


Includes the ongoing radar-guided measurement and monitoring of rainstorms and supplementary calibration based on ground rainfall quantity and rate measurements; studies of anomalous rainstorms and their impact on the hydrological system; formulation of descriptive models and statistical quantitative and frequency rainfall predictions within the framework of soil preservation and drainage research.

Hydrology and hydrometry
Includes the measuring and monitoring of natural and artificial conduit water-flow; the impact of agricultural, open and developed land on conduit water flow, and the impact of flow regimes on the environment; the processing and analyzing of peak discharge and flow volume data; the formulation of predictive models for discharge, water volumes and tidal waves within variant probabilities.
Soil Salinization
Includes the study of soil salinization processes; the development of methods to measure salinisation parameters; the improvement and adjustment of subterranean drainage methods to solve salinization problems; the building and adjustment of models to describe salinization processes and the movement of water and salt through saturated and non-saturated soil; the suggestion of computerized drainage solutions for the reduction and prevention of soil salinization.

Soil erosion and developing methods for the preservation of soil and water
Includes the studying and developing of agro-technical, engineering and chemical methods of monitoring above-ground flow and of the reduction of runoff and erosion; the development of agricultural processing tools and methods to increase surface runoff and absorb runoff water in order to streamline soil and water preservation; the development of methods to improve the water balance in agricultural fields while reducing fertilization and using urban waste compost to enable the reduction of excess urban waste; the study and application of overall solutions for drainage basin management for the reduction of water damages on the one hand, and the increase of water usage efficiency on the other hand.

Building and updating databases
Includes the construction of databases from varied data gathered in the following fields:
Processed data on rain quantity and rate, of various durations and probabilities.
Processed data of peak discharges in various probabilities, including maintaining an up to date regional-based probability model to calculate content discharge in drainage arteries.
A soil salinity database containing data from varied agricultural land and from areas near water reservoirs.

Computerized mapping, Geographic Information Systems (GIS), image processing and GPS
The employment of computerized mapping, image processing (of aerial photos and satellite imaging) and GPS-based point location methods as tools for analyzing contours and runoff coefficients of drainage basins.
