Basin plans have become a core element of water management in the 21st century. Systematic analytical scrutiny of the contents of basin plans is nonetheless scant. This paper develops a framework for assessing basin plans and systematically applies it to understand how contents of basin plans vary. The paper synthesizes a definition of ‘basin plan’, generates a classification system for basin plans, and proceeds to classify a regionally diverse set of 23 basin plans. Major findings are that basin plans typically contain the components and sub-components suggested in best-practice guidelines. Focus on some issues that are presumably central to water management such as water quality and quantity is nonetheless comparatively low. Disaggregating basin plans suggests that developing-country transboundary plans are more geared towards hydropower development, navigation and coping with uncertainty, while developed-country and national plans appear to focus more on issues such as water quality and fish management. It is hoped that findings contained in this paper support future basin plan development by informing those crafting basin plans of the options available to them.
Automatic control valves: how to assess ACV applications
As automation and computers claimed a foothold in the operation and control of reservoirs and elevated water tanks, the industry moved the valve control from mechanical automatic control valves (ACV) to actuated butterfly and ball valves. The primary reason? Actuators can be controlled by SCADA systems, which have been almost universally implemented in modern water systems. Because of this, many water system managers and operators have stopped purchasing the mechanical altitude valve which was the standard for...
Condition assessment program continues in North Queensland
Justification of an ongoing condition assessment program can, at times, be difficult for water utilities. However, successful inspections that deliver actionable outcomes on how to manage aging assets make this justification much easier. Certainly that was the case for Mackay Regional Council (MRC) when it engaged the services of Pure Technologies (Pure) to conduct a variety of condition assessment inspections on their critical mains in order to improve their understanding of these aging assets. For MRC, the...
Assessment of groundwater quality and health risk in drinking water basin using GIS
Eğirdir Lake basin was selected as the study area because the lake is the second largest freshwater lake in Turkey and groundwater in the basin is used as drinking water. In the present study, 29 groundwater samples were collected and analyzed for physico-chemical parameters to determine the hydrochemical characteristics, groundwater quality, and human health risk in the study area. The dominant ions are Ca2+, Mg2+, HCO32−, and SO42. According to Gibbs plot, the predominant samples fall in the rock–water interactio...
A methodological system for hydraulic heritage assessment: a management tool
Traditional irrigation systems are spatial units with a remarkable cultural and heritage value, which in turn generate water landscapes. They are part of hydraulic heritage, which includes material, ideational and symbolic assets. However, the assets related to historical irrigation systems and their landscape units have been poorly studied and evaluated. This paper develops a methodological system for the assessment of hydraulic heritage which combines basic and multi-criteria quantitative techniques. The...
Assessing buried infrastructure deep under buried infrastructure
In preparing for its water future, the Region of Peel (Peel) adopts a unique assessment strategy for a newly constructed potable water transmission main that extends deep underground through the heart of Peel Region. The effort is paying off, with Peel decision makers gaining a better understanding of this pipeline as it comes into service.
