This book was released on 2013 with total page 392 pages. Available in PDF, EPUB and Kindle. Book excerpt: Management of nutrient pollution has been recognised as a growing challenge in water resources management. To evaluate the pollution nature and its occurrence in time and space would be necessary for effective management control in changing environment. This was a main focus for developing a new model for this study. It was aimed to incorporate catchment and in-stream process dynamics into nutrient simulation at a river basin scale. The study proposed a novel approach to describe the nutrient generation and release from land surface to the river network system. The surface component takes account of various sources of nutrients and estimates nutrient generation from different land uses. The key nutrients are nitrogen (N) and phosphorus (P). By describing the transformation process of mineralization, immobilization, nitrification and denitrification, the rate of generation of mineralized N and nitrate are determined for different land use types. Similar process is considered for P, which takes account of adsorption and desorption and process of mineralization of P in soil and determines available P in transport. The key innovation in the research was in the mechanism of linking hydrology in relation to catchment nutrient release. The study proposed a flow capacity based nutrient export for accurate prediction of nutrient loads from catchments to the waterways. The seasonal variability and export through various pathways have been considered. First, the model the model was developed using sub-catchment based approach to test the various methods. Based on the outcome the grid-based model was developed. The applicability of the model was evaluated in two river basins, located in Australia and Japan, through calibration and validation. The model was also applied for climate change impact assessment in the Australian catchment. The model results show quite satisfactory performance. High intensity flood events were simulated for the Saru River, Japan. The Nash-Sutcliffe coefficient of model efficiency and r2 values are 0.83 and 0.9 for ORG-N, 0.75 and 0.90 for NO3-N, 0.82 and 0.87 for PO4-P, and 0.80 and 0.83 for PO4-P, respectively. Despite the limitations of observed records, the model could show a reasonable performance in simulating the long term seasonal variations in nutrient levels for the Latrobe River, Australia. The seasonality was strongly co-related with soil-moisture and climate condition, which was predicted well because of the process-based description. The key aspect of this research was enabling of hydro-climate based simulation for prediction of pollution level due to environmental change, which was demonstrated through climate change impact assessment. The effect of temperature rise on the catchment and in-stream process and its impact on NO3-N level was predicted for the Latrobe River. Based on the climate change projection for the region the scenarios were simulated, which revealed that the NO3-N levels are likely to increase by 18-42%. Developing percentile profiles of NO3-N for current and future condition, which are key indicators for water quality status, the study provides a stakeholder's decision making tool for adaptation measures.The integrated model provides a common platform for potential use in various watershed management issues including the regional application of the model for climate change application for soil and water management. The study suggests to incorporate hill slope soil erosion process in the sediment model, which could be useful for soil and land management. It is also suggested to incorporate river sediment and plant interaction modelling in river module so the hydro-ecological study is made possible. The river transport module was developed in such a way that it could also describe the transport process of other pollutants such as bacteria or heavy metals.

Download or read book Integrated River Basin Governance written by Bruce Hooper and published by IWA Publishing. This book was released on 2005-08-31 with total page 317 pages. Available in PDF, EPUB and Kindle. Book excerpt: Integrated River Basin Governance - Learning from International Experience is designed to help practitioners implement integrated approaches to river basin management (IRBM). It aims to help the coming generation of senior university students learn how to design IRBM and it provides current researchers and the broader water community with a resource on river basin management. Drawing on both past and present river basin and valley scale catchment management examples from around the world, the book develops an integration framework for river basin management. Grounded in the theory and literature of natural resources management and planning, the thrust of the book is to assist policy and planning, rather than extend knowledge of hydrology, biophysical modelling or aquatic ecology. Providing a classification of river basin organizations and their use, the book also covers fundamental issues related to implementation: decision-making. institutions and organizations. information management. participation and awareness. legal and economic issues. integration and coordination processes. building human capacity. Integrated River Basin Governance focuses on the social, economic, organizational and institutional arrangements of river basin management. Methods are outlined for implementing strategic and regional approaches to river basin management, noting the importance of context and other key elements which have been shown to impede success. The book includes a range of tools for river basin governance methods, derived from real life experiences in both developed and developing countries. The successes and failures of river basin management are discussed, and lessons learned from both are presented. The ebook for this title is available to download for free on the WaterWiki.

Download or read book Principles of Coding and Reimbursement for Surgeons written by Mark Savarise and published by Springer. This book was released on 2016-12-30 with total page 342 pages. Available in PDF, EPUB and Kindle. Book excerpt: This text provides the in-depth understanding of the mechanisms that guide coding and reimbursement. The text is meant to be useful to surgeons in practice, both in general surgery and in surgical subspecialties; practice management teams of surgical practices and to resident physicians in surgery. Part 1 of the text addresses the CPT coding process, the relative valuation system (RVU), the ICD-9 and ICD-10 systems of classification, Medicare Part B payment rules for physicians, the DRG system and Medicare Part A payment for hospitals, alternative payment models, and the myriad of quality measures of importance to surgeons. Part 2 of the text addresses specific coding in areas where surgeons historically have had the most difficulty. This is not meant to substitute for the available texts, software or courses on coding, but to provide the historical background and rationale for the specific coding rules. Principles of Coding and Reimbursement for Surgeons will be of great value to general surgeons and surgical subspecialists in private practice, academic institutions, and employed positions. It will provide direction to management teams from practice and institutional levels. It is also of use to surgical trainees and to researchers in health policy issues.

Available in PDF, EPUB and Kindle. Book excerpt: This book provides a comprehensive introduction to the Institutional Grammar, an approach for analyzing the design of institutions. To lay the foundation for the application of the Grammar for different application areas, the book first provides a background of the IG, before motivating the introduction of an updated version of the Institutional Grammar, called the Institutional Grammar 2.0 that aims at representing institutions more comprehensively and with greater validity. The book then turns to applications and introduces methodological guidance alongside expositions of emerging analytical applications of the “Grammar” that include presentations of current practice, as well as developing novel analytical opportunities that the analyst can apply or build upon for their application. This book is aimed at students, faculty, and practitioners of diverse disciplinary backgrounds with varying levels of understanding of institutional analysis and experience conducting it.
