Currently Mr. Andreyev is the president of Andreyev Engineering, Inc., a consulting engineering firm in the Orlando, Florida area. After graduating from the University of Maryland in 1980 he started working as a geotechnical engineer with Jammal & Associates, Inc. in Winter Park, Florida. He quickly realized that groundwater hydrology and stormwater infiltration was an area of little research in the early 1980's and entered the School of Engineering at the University of Central Florida (UCF) in 1982. He concentrated his studies in the areas of groundwater hydrology, surface water runoff and stormwater management. For his Master's thesis he has researched the area of stormwater infiltration and develop a methodology to integrate the transient nature of unsaturated and saturated flow of water from retention ponds built in unconfined shallow aquifer systems.

He graduated from UCF in 1985 while still working for Jammal & Associates, Inc. and started to transition from geotechnical work to groundwater studies and computer simulation of groundwater flow. In 1989 he was contracted by the Southwest Florida Water Management District (SWFWMD) to develop a methodology for the investigation, evaluation and design of stormwater retention ponds. The project was successfully completed and the new methodology was adapted by the SWFWMD as the basis of review for stormwater retention pond permitting. Mr Andreyev continues to research the area of infiltration and groundwater flow and often teaches short courses on the subject.

Mr. Andreyev has authored papers and published computer software over the years in the area of stormwater infiltration and groundwater flow.

Course Description:

To design a stormwater retention pond, one of the analyses that engineers have to perform is the retention and recovery of polluted runoff water. The initial portion of stormwater runoff is typically directed to a retention pond and which contains the most polluted runoff water (the first flush). The polluted water must be fully retained within the retention pond for treatment and infiltration. This course will be limited to recovery analysis for dry retention ponds where the entire polluted water volume must be stored within the pond and then recovered by infiltration within a specified period of time.

The regulatory agencies generally establish the minimum criteria for recovery of the first flush volume, which is sometimes referred to as the pollution abatement volume. For a dry pond the designer must verify the pond's capacity to infiltrate the volume within a specified period of time. This course will present the analytical approach and the methodology to calculate the infiltration losses from a dry retention pond.

Course Objectives: This continuing education course is written specifically for professional engineers with the objective of relating to and enhancing the practice of engineering.

Course Description:

This course is intended to present a systematic methodology for the determination of the type of field and laboratory tests needed and the minimum number of tests to be conducted for the design of a stormwater retention pond system.

Typically, soil borings and hydraulic conductivity tests are conducted for a stormwater retention pond system to evaluate the capacity of the pond to retain and infiltrate stormwater runoff. This is applicable to retention ponds built in sandy unconfined aquifer systems. The number of soil borings and hydraulic conductivity tests performed are usually dependent on many factors, not always obvious to the investigator or a designer. In some areas, the regulatory agencies have established criteria for a minimum number of soil borings and hydraulic conductivity tests. However, judgment and experience are usually applied in the decision making process and the selection of the number of tests can vary significantly from one investigator to another.

This course introduces a systematic methodology for a designer of a stormwater retention pond to select the minimum number of soil borings and hydraulic conductivity tests needed for a particular stormwater retention pond system. The course is presented in two parts. The first part presents the soil borings that are typically used to characterize the subsurface conditions, and the second part presents the hydraulic conductivity test methods and their applicability for a particular subsurface condition. The course concludes with the proposed methods to select the number and type of soil borings and the number and type of hydraulic conductivity tests needed for a particular retention pond system.

Course Objectives: This continuing education course is written specifically for professional engineers with the objective of relating to and enhancing the practice of engineering.

Course Description:

This "Green Irrigation Fundamentals — Balancing Aquifer Recharge and Withdrawal" is an introduction to an irrigation water demand calculation methodology, which is presented specifically for Florida, USA, but the methodology is applicable to anywhere in the world where similar water management challenges exist and where conservation of water resources is important.

This methodology is presented to allow for a systematic approach to evaluate and determine the optimum irrigation water demand for a particular house, a residential development or commercial development or any other project where impervious surfaces are created and the land use is changed to reduce evapotranspiration water losses.

The approach is relatively simple: if the amount of irrigation water used is equal to the amount of additional water created by the improvements to recharge the aquifer, then the net effect is zero (no impact).

The primary objective of this short course is to introduce a methodology that can be used by individual home owners, developers, engineers, planners, regulators and any other water managers who are interested in the conservation of water and a systematic application of water use restrictions based on scientific principles.
