1. Introduction
There is growing public concern about environmental issues, and such topics as global warming
and sustainable growth are frequency the subject of comment in the press and other media. Public
pressure continues to grow for greater efforts to be made up the environment and remedy the pollution
and degradation that has arisen over the last hundred years.
Water makes up a major part of the environment, together with land and air, and is vital to the
maintenance of life (J.C.CURRIE and A.T.PEPPER 1993). Water, like energy, clean air and solid
organic and soil organic matter makes an essential contribution to the maintenance of economic
productivity, social well-being and lifestyle and the maintenance of nature and ecosystem services
and various aspects should be treated from that perspective. Water resources are under stress worldwide and one of the elements of this stress-water quality has increasingly become a crucial issue for
researchers and scientists in their studies (Tasuku Kato 2005). With the developing industrialization
and increasing populations, the range of requirements for water has increased together with greater
demands for higher quality water. It is estimated that 8% of worldwide water use is for household
purposes (drinking water, bathing, cooking, sanitation and gardening), 22% for industrial uses
(mainly hydropower or nuclear power), and 70% for crop irrigation (Sterling and Vintinner, 2008).
Regarding the demand for quality water for agricultural irrigation, there are no national standards or
regulations for irrigation water quality. Irrigation of food crops presents a possible health risk to food
consumers if the quality of the irrigation is inadequate, particularly with respect to pathogens and
toxic compounds. In term of agricultural use of water, agricultural ponds are dominant a considerable

amount of water for irrigation. The properties closed water body leads to accumulating the pollution
sources in the lake. It depends on the characteristics of a lake that has its own pollutants sources. One
of the most common pollutants is organic contaminant which is the reason of many serious water
issues in the water bodies. The annual temperature cycle is one of the most significant determinants
of the physical, chemical, and biological interactions of a lake or reservoir. The significance of thermal stratification to the eutrophication process and to reservoir restoration lies in the separation of
the upper and lower lake zones during the summer through differences in water density. The separation of layer prevents the transport oxygen has caused the loss of oxygen in the deep part of the
reservoir which is called anaerobic state. As summer progress, the process increase phosphorus, nitrogen in the hypolimnion and frequency are transported vertically in winter season into the water
surface area where to subsidize algal growth. This biological process response to the excess nutrient
input to the lake is known as eutrophication. Eutrophication is responsible for many water supply
problems (WHO, 1981). Common lake and reservoir problem are excessive algal growth, deficient
fishery. Water quality in terms of transparency, color, and the odor is often related to a number of
algae present. Cultural eutrophication is a central concern in lake management. Protection of lakes
and reservoirs from eutrophication has been of international concern for a number of years. Therefore,
water quality assessments and forecasting become a matter of urgency for water quality management

issues. Although many methods have been developed to rectify the adverse impacts of cultural eutrophication. It consists of evaluation and controlling activities of the water quality in field, simulation
model in the laboratory or mathematical modeling on the computer etc. Among them, using mathematical modeling is a high effective method to assess the relative importance of processes affecting
eutrophication and the potential success of different lake treatment strategies. Moreover, the lake
manager must acquire a sufficient database to determinate what dominant lake progresses to cause a
lake problem, decide which management techniques affect lake processes sufficiently to reduce the
problem, and evaluate cost and benefits of management techniques. Modeling is a tool that can provide the information for the decision-making process. In addition, the mathematical model has a capacity for utilizing in multi-objective. Ideally, it offers the lake manager a sophisticated evaluation at
a comparatively low cost to analyze expensive lake management technical and to optimize the money
spent on a lake management program. Because of the strength of its, the mathematic model has applied for worldwide to simulation the variability of dissolved elements such as nitrogen (NH4+, NO3) or major ions Carbonate (C), Calcium (Ca)…etc as well as the seasonal variation of Chl.a and DO
in eutrophic water bodies. However, the evaluation and simulation the variability nutrient salts concentration are considerable differences between aerobic lake and anaerobic lake. It is explained that
the concentration of nutrient varies dramatically depending on the erosion mechanism in the bottom
anaerobic condition lake. Hence, the internal nutrient loading of phosphorus and nitrogen can’t display sufficiently in these modeling. Moreover, there is no research on modeling the variation of sulfide under anaerobic state in the organically polluted reservoir. To overcome these limitations, the
ecosystem model meets the requirement two criteria (i) simulation the characteristic of dynamic characteristics of water quality (ii) reflect the biological-chemical process simulation such as nitrificationdenitrification, iron reduction and sulfate reduction under anaerobic conditions.

The purpose of this study is to develop a modified ecosystem model based on a general hydrodynamic model in order to apply for water quality simulation under anaerobic conditions. To achieve
this objective, the operation is followed by these steps (1) Evaluation and analysis the dynamic characteristic of water quality throughout by data observation collection. Data includes of the collection
from the surface to bottom of the lake at the central of study areas and laboratory activities consist of
concentration measurements, biological determination. (2) The results are utilized to correct and
develop by applying Fortran programming computer software.

Study area and observation data

2.1

Study area

The target of the study is a regulating reservoir (No. 5 reservoir) (Figure 2.1) that is located in
Ito campus of Kyushu University, Itoshima Peninsula, Fukuoka Prefecture, Japan. No. 5 reservoir is
a deep water body (water surface area of ca. 13,800 m3, pondage of ca. 63,000 m3, and maximum
water depth of 8m), was created to store rainfall and supply water for cultivation activities at the
downstream crop area. There are two box culverts that include box culvert 1 (BC1), located at the
Southwest of the reservoir, and box culvert 2 (BC2), located at the North of the reservoir (Figure
2.1). The inflow from BC1 is treated by a pollution treatment facility to reduce the concentration of
organic material before going to the No.5 reservoir. Most of the organic pollution comes from BC2
where runoff directly flows into the reservoir without any treatment. The watershed of the reservoir
is deforestation area and agricultural regions. Therefore, runoff usually carries a lot of humic acids
from these regions to the reservoir, making heavy organic pollution in the water body. Every summer,
the high concentration of organic matter is the main reason to exacerbate the thermal stratification,
leading to the drop of DO at the deep parts of the reservoir. At the benthic zone, due to lack of DO,

many biochemical reduction reactions such as iron reduction, sulfate reduction occur, release nutrient
salts, iron, and sulfide, causing considerable deterioration of water environment.

Observation data

In 2015, the monitoring periods began on April 1 and completed on December 9. The water
quality analysis was conducted once a week. In the 6-month survey, there are two kinds of water
quality analysis activity were implemented, including outdoor analysis activities and indoor analysis
activities.

2.2.1

Outdoor analysis activities

The outdoor analysis activities that consist of DO, ORP, EC, pH, water temperature and water
samples collection were conducted on the fixing point at the center of the reservoir. Water samples
were collected 1-m intervals from 0m to 8m. Nine water samples in total were contained in the two
liters plastic bottles and save on the boat before were analyzed in the laboratory by many measurements to get the water quality data. DO, ORP, EC, pH and water temperature were directly recorded
in the reservoir 0.5-m intervals by using a water quality probe. A Secchi-disk, circular disk 30 cm in
diameter, was used to determine transparency. The meteorological data that consist of air temperature,
relative humidity, wind speed, solar radiation, and rainfall were measured automatically every ten
minutes. The detailed data of outdoor analysis are shown in Figure 2.2 and from Table 2.1 to Table 2.6.
2.2.2

Indoor analysis activities

Water samples were analyzed in the laboratory in order to determine the concentration of water
quality indicators including Chlorophyll-a, TN, TP, TOC, DOC, NH4-N, NO3-N, PO4-P, Cl, E254,
SO42-, silica, total iron ion, sulfide. The concentration of Chlorophyll-a was determined by using a
submersible fluorescence probe (FluoroProbe, bb-Moldaenke, Germany). The concentration of NH4N was measured by Quick Ammonia AT-2000. The analysis of NO3-N, SO42- and Cl were analyzed
by an ion chromatography method using AS50 auto-sampler (was manufactured by DIONEX Corporation). The concentration of sulfide was determined by using methylene blue method (DR5000,
