Water Balance

The impacts of water infrastructure and climate change on the hydrology of the Upper Ganges river basin – A research report by IWMI

GangaThis study by International Water Management Institute (IWMI) assessed the variability of flows under present and ‘naturalized’ basin conditions in the Upper Ganges Basin. The Ganges river system originates in the Central Himalayas, and extends into the alluvial Gangetic Plains and drains into the Indian Ocean at the Bay of Bengal. In the upstream mountainous regions, hydropower is the main focus of development with mega and micro projects either under construction or being planned in both Nepal and India.

After the main river channel reaches the plains, it is highly regulated with dams, barrages and associated irrigation canals. All this infrastructure development and abstractions affects the river’s flow regime and reduces flows, which, in turn, impacts downstream water availability, water quality and riverine ecosystems. Furthermore, there are concerns that climate change is likely to exacerbate the water scarcity problem in the Ganges Basin. Therefore, modeling the hydrology of the basin is critical for estimation, planning and management of current and future water resources.Read More

The Water Footprint Assessment Manual: Setting the global standard – Methods for water footprint accounting by the Water Footprint Network

WFNThis book by Earthscan contains the global standard for ‘water footprint assessment’ as developed and maintained by the Water Footprint Network (WFN). It covers a comprehensive set of definitions and methods for water footprint accounting. It shows how water footprints are calculated for individual processes and products, as well as for consumers, nations and businesses. It also includes methods for water footprint sustainability assessment and a library of water footprint response options.

A shared standard on definitions and calculation methods is crucial given the rapidly growing interest in companies and governments to use water footprint accounts as a basis for formulating sustainable water strategies and policies. The current manual is an updated, revised and expanded version of Water Footprint Manual: State of the Art 2009, published by the WFN in November 2009 (Hoekstra et al, 2009a). This new edition has been produced after intensive consultations with partners and researchers worldwide. Directly following the publication of the Water Footprint Manual, all partners of the WFN were invited to provide feedback on the manual.

Groundwater flow modelling and aquifer vulnerability assessment in Yamuna–Krishni sub-basin of Muzaffarnagar district – A study by Central Ground Water Board and Aligarh Muslim University

This report by Aligarh Muslim University and Central Ground Water Board (CGWB) deals with groundwater flow modelling and aquifer vulnerability assessment in Yamuna–Krishni sub-basin of Muzaffarnagar district. For evaluation of the groundwater resources and for minimizing the error of estimation, the system has been evaluated through aquifer modelling where water balance is established using partial differential equation of groundwater flow and is solved with boundary and initial boundary conditions.

Mitigating the potential unintended impacts of water harvesting - A WHiRL Research Report

This report under the WHiRL research project by the Natural Resources Institute (NRI) identifies the potential unintended impacts of water harvesting so that, if at all possible they are avoided altogether, but if these do occur, they are recognised at an early stage and steps are taken to mitigate their affects. It highlights evidence that is emerging about water harvesting in semi-arid areas, on how water if used inappropriately, can lead to inequitable access to water resources and, in the extreme, to unreliable drinking water supplies.Read More

Groundwater modeling – A presentation by ACWADAM

This presentation by ACWADAM deals with groundwater modeling using the Water Evaluation and Planning System (WEAP) model. WEAP is a microcomputer tool for integrated water resources planning and operates on the basic principle of a water balance. WEAP is distinguished by its integrated approach to simulating water systems and by its policy orientation. It provides a comprehensive, flexible and user-friendly framework for policy analysis.Read More

Why study weather – A presentation by ACWADAM

This presentation by ACWADAM deals with weather, the most fundamental process that shapes the earth. Meteorology, the science of studying weather, is described where some predictions can be made using atmospheric conditions or some data can be generated using simple equipments. These can in turn be used for measurement of weather for better implementation of a watershed project.Read More
