Alpha Hydraulic Engineering Consultants Co., Ltd.
The earth has water to cultivate all lives including human beings.
Rain drops on its surface will permeate into the ground to begroundwater, or they will flow through the forest, farmland and city down
to the river and ocean, to bring enormous benefits to lives on the earth. To
protect the water cycle for its eternal utilization, AHEC provides
excellent consulting services in the hydraulic engineering. Toward“harmony with the environment”, “symbiosis with nature” and“sustainability”, AHEC will create a prosperous future for the next
generation. We will continue our efforts as a leading consultant withexpertise in the hydraulic engineering.

Investigation

The investigation is the first step to the water engineering for Ocean, Coast, River, Pondand Lake.Especially the ocean has innumerable possibility and unknown world to beexplored, long-term and cautious investigation with the comprehensive view and considerationis necessary. Even for the complicated issues, the solution will be found out by the records
research with strict observation and perspective. Such manner to the investigation has
not only been accumulated as our resource but also developed our technological competence,
which is effectively utilized in our various projects.

Analysis

In Ocean, Lake and River, various phenomena are observed in its water.
The planned facilities in the water for the development and maintenance tobe harmonized with the natural environment, therefore an accurate
assessment and evaluation for its effect to be inquired into by the analysis of
the present situation, condition and past records. We, AHEC, always pursue
the advanced simulation technology so as to analyze the prospective
phenomenon and propose the design of the high efficient and economical
facilities, which will mitigate environmental load.

DesignSocio economic situation has been considerably changed and matured to the level in the Europe andUSA for this half of the century. Consequently, the social demands also have been changed as taking aqualitative value as an environmental view and efficient cost-performance. Therefore, we have to develop
comfortable and safer infrastructure with Zero Environmental Load and maintain them as long aspossible. However, many undeveloped countries exist in the world and they are fighting with shortageof food and water, and unstable political situation, we also have to contribute to them in the field of theinfrastructure stock to prevail their severe social situation. We, AHEC, are continuously making the best
endeavor to find the solution for the social stock issue in terms of marine, ocean, lake and river, and todesign and manage them by our reputable expertise and technique cultivated in these three decades.

important for the formation and sustainable development of the affluent water environment
to preserve/recover soundly natural environment. We address the solution to the various
environmental issues for the area of an enclosed coastal seas (including anchorage in ports),
lakes/dams, tideland and seaweed bed to be figured out , and some measures to be proposed
based upon our comprehensive knowledge to the circulation mechanism of the nature.

The 21st century will be an era of conflict over water instead of the territory
conflicts in 20th, therefore preservation of the favorable aquatic environment isgetting very important subject for us. Also, in addition to the frequent occurrence ofsevere damage by natural disaster such as flood and tidal wave, addressing to theincreasing urgency of damage by tsunami has become important issue. Thus, we willpropose the river environment management required in the 21st century withrespect to “watershed”, “running sand system”, and “estuarine region” as well as aninvestigation, an analysis, an evaluation and a project planning for the disasterprevention and an utilities protection in order to provide solutions and contribute tosociety as much as possible.

With a remarkable development in a field of IT, a new improvement of IT infrastructure has
been required as a national strategy in the advanced information society of the 21st century.
In this situation, we are facilitating an establishment of information system which makes
conventional framework more efficient and sophisticated by using tools such as GIS(Geographical Information System) in various fields such as port, fishing port, coast,river.
Also, we can make a proposal regarding utilization method for exchange and distribution ofinformation created by system through networks in order to widely utilize insocial life.
