Evaluation of hydrological parameters and temperature regime of watercourses of various orders comes to the fore when studying the scientific problems of hydrobiology of watercourses and solving practical problems of development of fisheries and gold exploration in the regions of the Far North. This became particularly relevant due to a significant reduction in hydrological observations since the early 1990s.

Waste is produced in a number of activities and transported within the drainage basin by natural as well as man-made processes.

Tools are needed in order to decide on how to minimise the negative effects of waste fluxes, supported by appropriate monitoring procedures.

Abstract:

Reusing reclaimed municipal wastewater contributes to the water management strategy of Mediterranean seaside resorts. By supplying irrigation water, it allows the lay out of lanscaped areas and of golf courses. By reducing or eliminating the discharge of treatment plant effluents to water courses and to the sea, it reduces the contamination of bathing water and coastal ecosystems. The development of this policy depends on the availability of cost effective processes able to decontaminate the effluents of the existing wastewater treatment plants.

Abstract:

The water operator plays an important role in water safety; however, little published research exists that has examined this role. The purpose of this study was to develop a greater understanding of the experience, existing knowledge, confidence and future training needs of the small, non-community drinking water operator in Ontario in order to help guide future outreach and training opportunities. A cross-sectional telephone survey of 332 small, non-community drinking water operators in Ontario was conducted in July and August 2011. Survey questions pertained to respondents' experience as ope

It was found that the disappearance of BOD5 and NH3-N could be approximated using first-order kinetics, but the kinetics of TP removal were unclear. The reduction rate co

In the case study, the proposal consisting of increasing the minimum flow rate on a non-permanent river by means of discharging reclaimed water is studied.

Since reducing energy consumption is a priority for an enterprise, economic effi ciency in general is directly related to the use of pumping equipment. The demand for electricity for pumping equipment will depend on various factors: the operating modes of pumping stations and installations, the equipment used measures to reduce the cost of electricity consumed, etc. The current practice indicates extremely inefficient operation of pumping equipment. Currently, a large number of pumping stations of water supply and sanitation systems operate in an uneconomical mode. Very often, this is due to i

Soil erosion in Ireland is a considerable environmental problem with respect to the ‘off-site’ transport of sediment and pollutants out of fields and into nearby water courses and the neighbouring environment. This paper examines this important issue by presenting evidence for past and present-day soil erosion in Ireland through the use of secondary documentary and primary observational evidence. An original modelling-based study is also conducted at six locations across the north of Ireland in order to project future soil erosion rates for Ireland under a changing environment.

Benzothiazoles are frequently present in wastewater from rubber related applications, and may be found in surface and underground water bodies causing significant environmental impact. Cost effective treatment processes to deal with such contaminants are needed in both small and large-scale applications. These compounds are poorly biodegradable and could be removed by ozone oxidation before discharge to recipient water courses. Unfortunately, there is limited experimental data reported in the literature on such processes involving benzothiazoles. This article presents experimental data on ozon

Furthermore, a seasonal dependence of vegetation parameters has to be accomplished for a successful application. Many approaches neglect inter-annual variability and shifts due to climate change. In this paper a more comprehensive approach from literature was evaluated and applied to long-term water balance simulations, which incorporates temperature, humidity and maximum bright sunshine hours per day to calculate a growing season index (GSI).
