Environmental Risk Consulting Service

We promote environmental projects based on accurate understanding about nature and the environmental conditions. In carrying out a project, it is necessary to protect and conserve the environment as well as ensuring economic efficiency and safety. In addition, most advanced technology and a lot of information are required for prediction and evaluation of the environmental impacts of construction projects or infrastructure developments. In order to carry out a successful project, we are engaged from planning, implementation, completion to follow-up surveys, and conduct various tasks including in situ investigations and rigorous simulation making the best use of abundant information based on highly accurate prediction and evaluation.

¡Ecosystem research in Tidal Flat Zones
With the increase of restoration projects in tidal flats, examination about their effects and management have been made for further progresses. For adaptive management, we conduct a series of ecosystem surveys in tidal flats from in situ investigation, evaluation/examination to monitoring. Also, evaluation and examination have been conducted from ecological perspective using Habitat Evaluation Procedure (HEP).

¡Coastal Management Master Plan Based on the New Coast Act
In conducting multi-ministerial/governmental coastal management, it is imperative to confirm the factors of coast formation through understanding and analyzing sedimentation (stratification order, history of stratification) specific to respective coasts.The coastal management plan is essential not only for coastal erosion problems but also for maintenance of existing facilities.

¡Numerical Calculation
It is mandatory to conduct predictive evaluation by numerical calculation in order to examine resolutions dealing with problems caused during development and construction processes and validate the effects of existing facilities. We conduct predictive evaluation about water quality related parameters from river upstream reservoirs to oceans, marine physical phenomenon including currents and waves, and associated topographical changes.

¡Numerical Simulation for Dam Lakes (note: another term for dam lakes is reservoir or man-made lakes)
In dam lakes, there are diverse problems such as cold water, long-term turbidity and nutrient depletion. We use various numerical simulation models in order to deal with such problems. We provide examination service for dam lakes using the one-dimensional model for general study and the two-dimensional model for detailed examination.

¡Environmental Remediation Consulting
Diverse environmental remediation technologies have been developed according to groundbreaking technology development in recent years. However, good effects will not be produced if the technologies are not used in proper gways and quantities.h We conduct investigations about the characteristics of the targeted areas, and propose a most appropriate remediation method through examining the best technology combination from existing and developing technologies.

¡Coastal Eco-Monitoring Surveys
Commonly, the belt transect method has been used for intertidal biological research. However, we conduct coastal eco-monitoring surveys through focusing on targeted organisms, observing species spatial distribution and using GPS mapping.
We developed this simple, mid-to long term and over time monitoring method.

¡Riparian zone census
In Japan, gBasic Survey Manual for Riparian Bio-Censush was revised in 2006. We are capable of conducting all types of basic surveys described in the manual of the Riparian Bio-Census, and providing consistent services from preliminary surveys, field surveys, data inputting to data system management. We also provide technical support and field survey for the Riparian Bio-Census for local residents.

¡Fish and aquatic life survey
gBasic Survey Manual for Riparian Bio-Censush has been revised in 2006 fiscal year, the use of electric shocker has been added among authorized fish and aquatic life survey. This method has recently been enjoying a growing popularity as a reliable method among quantitative survey methods because it is easy to use and doesnft rely on surveyors` technical skills. Electric shocker sends short electric waves into the water, the fish, is captured by a scoop net while being unconscious for a short moment, and immediately released after measurement. Our survey history has proved there is hardly any harm caused to the fish by the use of an electric shocker.

  ¡Raptors Survey
In considering natural environment in local areas, the existence of raptors that are on the highest level of the food chain are being more focused. To consider conservation of their habitats and breeding grounds, our well-experienced surveyors conduct surveys and compile reports that give a comprehensive picture of environmental conditions.

¡Demonstration Projects for Water Environment Improvement Using Ecosystem Based Solutions
We conduct demonstration projects for water environment improvement making the use of naturefs purification abilities. We construct artificial tidal flat land in seaside parks adjacent to cities, and install rubble masonries and floating rafts in the land. The efficacy of the facilities has been continuously examined through monitoring of biota restoration and investigating concentrations of nitrogen and phosphorus.
