A Treatability Index is developed to allow comparison of different reservoir waters according to their effects on a water treatments works. For the water treatment works which employs rapid gravity filters, the index is the product of the algal concentration, the clarification coefficients of algae and the filtration rate. The index is applied to reservoir waters within Thames Water area. Algae observed in reservoirs are grouped according to their shapes. Among these groups, twenty frequently observed species were selected and their clarification coefficients were measured. The treatability index was then evaluated for different waters and at different times of the year. The results were correlated to the filter run lengths and the development of headloss across the filters.

Cooling reservoirs of thermal power plants represent the special class of natural/ engineering systems with, on the one hand, natural geo/systems as one subsystem and, on the other hand, production/technological units as the other subsystem. Studying of these ecosystems’ functioning regularities seems to be helpful for water quality management and rational organization of water use. Besides, it is topical due to the low level of the relevant knowledge in the North of the Western Siberia. The authors for the first time in the Middle Ob Region have carried out a two-year session of monitoring of hydro/chemical indicators and temperature regime of the thermal power plants cooling reservoirs in the riparian stripe of water area. All previous investigations were done only by industrial water users within the frameworks of production monitoring in terms of three indicators in three points of the cooling reservoir water area downstream the power plant dam. Spatial distribution of concentrations of biogenic ions, salt composition, pH, organic matter, and metals in specific natural/technological system of the Surgut hthermal power plants’ reservoirs has been analyzed for the first time for the conditions of the Western Siberian taiga zone. Sources of anthropogenic pressure upon a water body have been identified. According the results of the indicators’ spatial distribution analysis three sections of the Surgut reservoir water area have been separated: a background section of the Chernaya River; a section upstream the dam with predominantly recreational character of the anthropogenic pressure; and a sectio0n downstream the dam with anthropogenic pressure of technological origin. According the outcomes of the correlation analysis indicators of the anthropogenic pressure character have been reveald.

Abstract Tourism is one of the important economic sectors in Indonesia. In 2009, tourism ranked third in terms of foreign exchange earnings after oil and gas commodities and palm oil. (Indonesian Ministry of Culture and Tourism, 2009). Based on data in 2016, the number of foreign tours coming to Indonesia amounted to 11,525,963 million or grew by 10.79% compared to the previous year. The natural and cultural wealth is a critical component in increasing tourism in Indonesia. Because of the importance of tourism to the Indonesian economic sector, several regions in Indonesia need to be considered and developed by local government tourism objects.

The Kaligesing area is part of the western part of the West Progo Dome. As the hard water area, water resources should be important problem to support rural development. The characteristics of the drainage as an indicator of water resources potential need to be understood in order to assess water potential. This paper wants to describe drainage characteristics as one of potential water resources indicators. The sufficient water resource is important for rural development. Result of the research shows that geological conditions allow this area to have relatively little water potential, but surface water can develop through rock-controlled flow patterns and geological structures. The flow characteristics in the area show rectangular, sub dendritic, and trellis patterns. Rivers develop genetically with consequent and subsequent types. Based on the quantity of water, the rivers in the study area include the intermittent and ephemeral rivers. Meanwhile, based on tectonics these rivers can be classified as superimposed rivers, where geological structures facilitate the formation of rivers in the research area. The river order in the study area shows the order of 1 - 4. Meanwhile, the density of the river is 0.81 - 1.86 km/km2 with young to mature river stages.

At present, changes have occurred in the basin and water area of the Pavlovsky reservoir, affecting the chemical composition of the reservoir water. The combination of many factors (series of low-water years, termination of milk alloy, increase of recreational load, change of the share of diffuse contamination, etc.) do not allow to predict the modern trend of transformation of chemical composition of water. Considering that no gydro/chemical studies of Pavlovsky reservoir have been carried out in recent decades, studies of modern processes of transformation of chemical composition of this reservoir are relevant. For this purpose BashNIIVKh in 2018-2019 carried out hydro/chemical studies of the reservoir, in two years water samples were taken from the surface and from the bottom, as well as bottom deposits. In 2018 samples were taken according to 30 chemical indicators on 10 struts, and in 2019 – according to 10 chemical indicators on 7 struts. Also, the results of previous studies have been analyzed. Due to the large volume of the obtained material, this work only considered the results of studies of multi-year dynamics and modern trend of change of chemical composition of water (concentration of chemicals) in the water area of the Pavlovsky reservoir for 10 chemical indicators of water on 7 branches. Concentrations of Sr, Mn, petroleum products are shown to decrease along the length of the reservoir in the water; Increasing - Zn, Hg, phenols of organic substances; evenly distributed – Fetotal, Ptotal, Cu. In the many-year dynamics, Fetotal, Mn, petroleum products, phenols (in the inlet), COD show a trend of decrease of chemical indicators in water; Upward trend – Ptotal, Cu, Zn, phenols (in the exit). It has been established that the average annual concentrations of chemical indicators in the water of the Pavlovsky reservoir are related to the average annual inflow. The chemical values of Fe and Mn have a direct link (when the inflow increases, the concentration of the chemical index increases), and Ptotal, Cu, Zn, phenols and COD have a feedback (when the inflow increases, the concentration of the chemical index decreases).

The article discusses the possibilities of using various types of approximations for parametrization of vertical turbulent exchange for calculating and evaluating the hydrophysical characteristics of the wave regime in the accumulative coastal zone of the southwestern corner of the Tsimlyansk reservoir. It is impossible to carry out these studies without using various types and classes of approximations for parametrization of vertical turbulent mixing. Algebraic models for calculating the coefficient of vertical turbulent exchange and semi-empirical turbulence models are compared. Using ADCP data on velocity pulsations for several stations to measure hydrological characteristics, the results of parameterization of the vertical turbulent exchange coefficient were analyzed. The developed numerical algorithms and the software package implementing them are used to study the pressure field, the velocity vector field of the aquatic environment and the prediction of the baric field for this section of the reservoir water area.

The vertical distribution of the reservoir water temperature depends on the scale of the reservoir, regulation manners, as well as the hydrological and geological conditions near reservoir areas. Based on water temperature observation from three different regulation reservoirs, this paper analyses the vertical distribution of these reservoirs water temperature. The preliminary conclusions are: for multi-annual regulation reservoirs, the upper zones usually have stable temperature stratification structures, while the lower zones have constant low temperature; for annual regulation reservoirs, water temperature distribution changes with depth; for the daily regulation reservoirs with low water depths present mixed vertical distributions of water temperature.
