The small drainage area of the Parramatta River and the erratic rainfall pattern over Sydney are responsible for strong stratification phenomena in the upper Parramatta River estuary following rainfalls. A simple model is proposed for the fate of storm water and its effects on the water quality of the esturary.

Biological Resources

Bragança's socioeconomic situation is highly dependent on estuarine and marine biological resources that are influenced by tidal cycles and climatology. Field measurements (hydrological, hydrodynamic and microbiological variables) were taken in the most urbanized zone from Caeté estuary to characterise the quality of the local environment. During the dry period, the estuary was more eutrophic and presented the highest temperature (30.5 °C in Oct./06), salinity (17 psu in Feb./07), pH (8.24 in Feb./07) and fecal coliform (> 1000 MPN/100 ml in Dec./06 and Feb./07) values. The phytoplankton Cyclotella meneghiniana, Coscinodiscus centralis and other r-strategist species were observed. The lack of basic hydric canalization was responsible for the local contamination, especially during the dry period when more concentrated wastewater from the city was emitted into the estuary, showing the human influence on the reduction of local estuarine water quality. In Bragança, the fishery is considered one of the main economic activities so, this contamination is worrisome because a large part of the local economy depends on biological resources and, thus, the contamination could negatively affect the environmental health of this Amazon ecosystem.

Negative Impacts

The main economic activity in the Jiu Valley is mining, which provides to the society an important content of mineral raw  materials required for the development and progress, representing  the main activity in producing the value chain. The majority of the  mining activities and other economic activities deployed along the  basin of the East Jiu generates both negative environmental impacts (more or less serious) and positive impacts such as those  related to employment, staff training, creating infrastructures etc. In  the most cases, the negative impacts of the human activities can  be much improved up to a point or even eliminated through the  remedial measures, particularly through environmental rehabilitation of the affected areas. But if a watercourse is strongly  affected by sediments generated by the human activity still on the  top side, the pollution will be  intensifed much more on the bottom  side with signifiant changes on the aquatic ecosystems and with an  impossibility of consumption and the use of the water resources by  the riparian population. The main objective of this paper consists of the identification and the description of all human activities  presented along the East Jiu and the analayses of the negative  influence exerted on the river water quality. To compare the water  quality of the East Jiu and monitoring its variations in time, it was  used the method water quality index (WQI), having the straight  purpose of aggregating individual indicators (expressed in physical units) in a unique water quality index.

Quality Status

The issues of freshwater pollutions and the high demand of clean freshwater for daily human activities have forced developing countries such as Malaysia to continuously monitor the quality of the freshwater. The present study objective is to present the trend of water quality status in the Kelantan River downstream, Peninsular Malaysia from 2005 to 2018. Water samples were collected during dry and monsoon seasons from a sampling station located at downstream of the Kelantan River. Water quality parameters such as temperature, pH and dissolved oxygen (DO) were measured in situ while other parameters were analysed in the laboratory based on retrieved water samples. Water quality status was determined based on National Water Quality Standard (NWQS) for River in Malaysia by calculating the water quality index (WQI) according to the concentration of six water quality parameters involving pH, dissolved oxygen (DO), biochemical oxygen demand (BOD), chemical oxygen demand (COD), suspended solids (TSS) and Ammonia Nitrogen (AN). The results showed that Kelantan River had good water quality during the dry season classified in Class II at 2005. The water quality was found to be slightly lower during the monsoon season in year 2006. In addition, increasing the number of construction, human activities in the land use areas, land use changes and the sewage water from domestic, industrial, wet market and food outlets in the Kelantan State have declined the water quality in Kelantan River from Class II (in 2005) to Class III (in 2010 and 2011) and to become Class IV in 2017 to 2018. The results of the present study are expected to give valuable information for the water managers in order to deal with better strategies in controlling the quality of freshwater at the Kelantan River and minimize the incidence of pollution-oriented problems, thus the water can be utilized for various water uses with appropriate quality.
