Available in PDF, EPUB and Kindle. Book excerpt: Groundwater development has shown phenomenal progress in our country during past few decades. There has been a vast improvement in the perception, outlook and significance of groundwater resource. Groundwater is a dynamic system. It is dynamic in the sense that the state of any hydrological system is changing with time, and in the sense that we are continually developing new scientific techniques to evaluate these systems. The total annual replenishable groundwater resource of India is around 431 BCM. Inspite of the national scenario on the availability of groundwater being favourable, there are many areas in the country facing scarcity of water. This is because of the unplanned groundwater development resulting in fall of water levels, failure of wells, and salinity ingress in coastal areas. The development and over-exploitation of groundwater resources in certain parts of the country have raised the concern and need for judicious and scientific resource management and conservation. A complexity of factors - hydrogeological, hydrological and climatological, control the groundwater occurrence and movement. The precise assessment of recharge and discharge is rather difficult, as no techniques are currently available for their direct measurements. Hence, the methods employed for groundwater resource estimation are all indirect. Groundwater being a dynamic and replenishable resource is generally estimated based on the component of annual recharge, which could be subjected to development by means of suitable groundwater structures. Mathematical models are tools, which are frequently used in studying groundwater systems. In general, mathematical models are used to simulate (or to predict) the groundwater flow. Predictive simulations must be viewed as estimates, dependent upon the quality and uncertainty of the input data. Model conceptualization is the process in which data describing field conditions are assembled in a systematic way to describe groundwater flow processes at a site. The model conceptualization aids in determining the modelling approach and which model software to use. Taking the base from my lecture notes delivered in various training courses during last 26 years and further editing and additions, I have developed this book titled “Groundwater Assessment and Modelling”. The book is intended to provide a comprehensive treatise related to assessment and modelling of groundwater. It includes chapters on assessment of groundwater potential, groundwater data requirement and analysis, basic concepts and guidelines for groundwater modelling, groundwater modelling software, modelling of unsaturated flow, modelling of sea water intrusion, and impact of climate change on groundwater resources. I hope this book will be quite useful for undergraduate and postgraduate students (water resources engineering), field engineers and researchers working in the area of assessment, development and management of groundwater resources.

Available in PDF, EPUB and Kindle. Book excerpt: Murray-Darling Basin, Australia: Its Future Management is a much-needed text for water resources managers, water, catchment, estuarine and coastal scientists, and aquatic ecologists. The book first provides a summary of the Murray-Darling River system: its hydrology, water-related ecological assets, land uses (particularly irrigation), and its rural and regional communities; and management within the Basin, including catchments and natural resources, water resources, irrigation, environment, and monitoring and evaluation. Additionally, the recent major water reforms in the Basin are discussed, with a focus particularly on the development and implementation of the Basin Plan. Murray-Darling Basin, Australia: Its Future Management then provides an analysis of the next set of policy and institutional reforms (environmental, social, cultural and economic) needed to ensure the Basin is managed as an integrated system (including its water resources, catchment and estuary) capable of adapting to future changes. Six major challenges facing the Basin are identified and discussed, particularly within the context of predicted changes to the climate leading to an increased frequency of drought and a hotter and dryer future. Finally, a 'road map' or 'blueprint' to achieve more integrated management of the Basin is provided, together with some 'key lessons' of relevance to others involved in the management of multijurisdictional river Basins. - Provides a consolidated account of the Murray-Darling Basin system; an area of global relevance to those interested in rebalancing river systems where the water resources have been over allocated - Offers a detailed analysis of the current system and its management, with a focus on water and ecosystem management - Discusses a number of key challenges, particularly those related to climate change, facing future reforms to the Murray-Darling Basin Plan - Provides a blueprint for changes needed to ensure the Basin is managed as an integrated whole (from catchment to coast)

Download or read book Groundwater Recharge Estimates for the Lower Tertiary and Upper Cretaceous Aquifers in the Williston and Powder River Structural Basins written by Katherine Aurand and published by . This book was released on 2013 with total page 202 pages. Available in PDF, EPUB and Kindle. Book excerpt: A numerical soil-water-balance (SWB) model was used to estimate groundwater recharge in the Williston and Powder River structural basins in the Northern Great Plains. The SWB model consisted of [1 km2] grid cells across the entire study area. Recharge was estimated for glacial deposits and exposed areas of the Lower Tertiary and Upper Cretaceous aquifer systems in the Dakotas, Montana, Wyoming, Saskatchewan, and Manitoba. The water-table fluctuation (WTF) and chloride mass-balance (CMB) methods were applied to local areas with available groundwater-level and chloride data. SWB model results were compared to the WTF and CMB results, potentiometric surfaces, and previous investigations. A sensitivity analysis was conducted for the SWB model input parameters. The annual SWB model recharge rates were averaged from 1981 to 2011. Average calculated recharge in the Williston basin was 0.190 in/yr [(1,281 ft3sec)] and ranged from no recharge to 4.71 in/yr. Calculated recharge decreased to the west and was greatest in the northeastern part of the basin where glaciofluvial deposits are present. Recharge was calculated to be about 1.1 percent of precipitation in the Williston basin. Average recharge in the Powder River basin was 0.136 in/yr [(248 ft3/sec)] and ranged from no recharge to 4.46 in/yr. Calculated recharge rates are greatest during the late spring and early summer for both basins. Recharge was about 0.8 percent of precipitation in the Powder River basin. The SWB models did not activate the surface-water flow routing algorithm; therefore, recharge is probably underestimated and a scale factor could be used to account for the additional recharge to downslope cells from surface-water runoff. Diffuse recharge estimates from the SWB models are reasonable and compare reasonably well with local recharge estimation results, potentiometric surfaces, and previous investigations. However, the SWB model results should be used cautiously, keeping in mind the assumptions of the model and the input data.
