“…The environmental pollution of the lake has been investigated by many researchers in various aspects (e.g. Ichiki et al, 1998;Ichiki and Yamada, 1999;Kobayashi et al, 1975;Naito et al, 2002). On the other hand, the deposition fluxes of PAHs have not been investigated yet which may change seasonally according to seasonal emission intensity of PAHs, seasonal state of the lake, and physicochemical characteristics of the individual PAH.…”

“…No attempt is made here to exhaust this research and discuss in detail all the available nonstructural and low‐cost structural controls, as it is fully covered by many studies (Tsihrintzis & Hamid 1997; Braune & Wood 1999; Ichiki & Yamada 1999; Jefferies et al 1999; Mehler & Ostrowski 1999; Ristenpart 1999). These references identify approaches to stormwater management with regard to financial and technical issues.…”

Urban runoff pollution sources are formidable obstacles to achieving water source goals in numerous municipalities. Ramallah district currently holds one of the highest rates of urbanization in Palestine causing a significant increase in surface runoff. Consequently, this causes increased flooding and a significant decrease in water quality due primarily to the accumulation of pollutants. To date, most research has focused on specifying temporal variations of stormwater quality parameters that include high uncertainties and also increase the risk of pollution control structures' failure. Spatial variations of the runoff quality are the key factor in nonpoint source pollution studies. This research investigates the spatial variability of urban runoff quality parameters in relation to land use of urban catchments. The research estimated pollutant concentration for improved and efficient design of pollution control structures for each land use.

“…The Macro Model was developed in consideration of the difference in pollutant runoff due to pollutant source and weather. The model structure and procedure for its parameter determination were shown in the previous literatures (Ichiki et al, 1996, 1998and Ichiki and Yamada, 1999b. Table 1 shows the basic equations (eqns.…”

Lake Biwa is the largest lake in Japan, and water quality in the lake is heterogeneous. Therefore, it is important for water quality management that spatial distribution of water quality in the lake should be clearly understood. The objectives of this study are to show a methodology and to develop a simulation system to calculate COD distribution in Lake Biwa taking internal COD production into consideration. This study also aims to examine transition of COD in the lake using the simulation system. In the simulation system, runoff loads of COD from the Lake Biwa basin are calculated by Macro Model for each tributary. The external COD concentration in 233 inshore meshes of the Lake Biwa water surface was calculated using the runoff loads. The internal COD was calculated using relationships among limiting nutrients, chlorophyll-a and COD. Then, the spatial distribution of water quality in Lake Biwa was calculated both for the external and internal COD by spline technique. Simulations using the system were implemented for 1986-1998, and a clear difference in characteristics between a drought year and a flood year was shown. In the result, it was shown that the simulation system developed here was available to calculate COD distribution in Lake Biwa, and that it had the possibility to explain the recent phenomenon of COD increase in the lake.
