In order to assist the water quality management in Miyun Reservoir, a spatial and dynamic simulation model system was built. In the model system, GIS was integrated with the WASP5 model. The integrated model system was then calibrated and verified in different sets of field data. The result showed that the integrated model system could characterize the Miyun Reservoir waters. Two scenarios were then designed and analyzed with the integrated model system. It was indicated that the water quality would improve if the cage fishery was banned, the algae blooms might occur in Miyun Reservoir if the low water stage ocurred but loads remained unchanged.

Suspended Particulate Matters

Currently, VNREDSAT 1 data have been commonly applied in studying disciplines of landscapes or socioeconomy. Nevertheless, there are limited studies using these data in water quality management. This article focuses on estimating amounts of SPM (Suspended Particulate Matters) from VNREDSAT 1 in Thi Vai river basin based on a popular formula with on - site adjustments. Results were validated by field data with an relative value R2 = 0. 79. This value represents that there is a potential of applying VNREDSAT 1 in studying SPM in water depending on certain circumstances of accuracy.

Water quality standards set in the past have not helped resource managers in the decisions that they face in seeking sustainable development. Resource managers are looking for meaningful information on water quality so as to evaluate the resource, set priorities for action, and to monitor progress. Resource managers need to know how water quality affects, and is affected by, catchment uses and activities. Examples of three wild and scenic rivers, the Nymboida, Murrumbidgee, and Hawkesbury/Nepean River systems, demonstrate how a ‘Total Catchment Management' approach to resource use and resource protection has advantages for water quality management.

Few Data

As a result of the construction of a barrage in the estuary of the Nakdong river the size of the estuary will be considerably reduced. In addition, a large river reservoir is created upstream of the barrage. Main points of interest are the effects of the discharge of raw sewage and treated effluent into the Nakdong river on the water quality in the projected reservoir and the water quality forecasts for the remaining part of the estuary, in relation with the existing plans for sewerage and sewage treatment for the city of Busan. In addition, measures to reduce the effects of the barrage and the outline of a water quality management programme are presented. Special consideration is given to the methodological aspects of the water quality study, i.e. the selection and use of mathematical models in a situation where input data are rather uncertain and only very few data for parameter estimation and model verification are available.

A conceptual framework is presented for optimizing the operation of regional monitoring networks which assist water quality management. The primary objective of the studied network is to determine the annual nutrient load carried into a lake by its tributaries. Following the description of the basic (single time–period, single water quality indicator) model, several extension possibilities and computational aspects are highlighted. The suggested methodology is illustrated by a numerical example, concerning the surveillance system on the tributaries of Lake Balaton (Hungary).

The Gulf Coast Waste Disposal Authority is a regional public agency created by the State of Texas to design and implement water quality management systems in three counties surrounding Galveston Bay. This article will outline the water quality management strategy employed by the Authority for a highly industrialized and populated region. Regional treatment and public and private sector cooperation will be presented as a management objective for muncipal and industrial waste disposal. A description of the background and operations of the Authority will be included along with examples of joint or combined wastewater treatment. The pressing problem of hazardous waste management in Texas will be discussed. The Authority's experiences with facility siting and public reaction will be summarized and a new approach to help resolve these issues will be presented. The article will conclude with some thoughts on strategic planning for public managers.
