This book was released on 2012-12-06 with total page 201 pages. Available in PDF, EPUB and Kindle. Book excerpt: A discussion of the role of modeling in the management process, with an overview of state-of-the-art modeling applications. The first chapters provide a background on the benefits and costs of modeling and on the ecological basis of models, using historical applications as examples, while the second section describes the latest models from a wide selection of environmental disciplines. Since management frequently requires the integration of knowledge from many different areas, both single discipline and multidiscipline models are discussed in detail, and the author emphasizes the importance of understanding the issues and alternatives in choosing, applying, and evaluating models. Land and watershed managers as well as students of forestry, park management, regional planing and agriculture will find this a thorough and practical introduction to all aspects of modeling.

This book was released on 2012 with total page 296 pages. Available in PDF, EPUB and Kindle. Book excerpt: Changing climates, human population growth, and aging infrastructure threaten the availability and quality of one of life's most vital resources, water. Hydrological ecosystem services are goods and benefits derived from freshwater that include flood damage mitigation, water for agricultural and commercial use, swimmable and navigable waters, and healthy aquatic habitats. Using computer algorithms inspired by biological and ecological processes known as evolutionary algorithms and on-site stormwater management practices such structural best management practices (BMPs) and green stormwater infrastructure (GSI), this research aims to maximize hydrological ecosystem services at the watershed-scale in both agricultural and urban environments by integrating these algorithms with the watershed model Soil and Water Assessment Tool (SWAT), and the hydraulic model Storm Water Management Model (SWMM). This dissertation first develops an information theoretic approach to global sensitivity analysis for distributed models, demonstrated using SWAT, and later uses the sensitive model parameters in a multi-objective automatic calibration scheme using multi-objective particle swarm optimization (MOPSO). Multiple alternative watershed-scale BMP designs (parallel terraces, detention/infiltration ponds, field borders, and grade stabilization structures) that help minimize peak runoff and annual sediment yield were simultaneously identified using SWAT coupled with the species conserving genetic algorithm (SCGA). Finally, using recently developed economic estimates called triple bottom line (TBL) accounting, watershed-scale GSI designs are identified that reduce combined sewer overflow volumes in an urban setting while maximizing the net benefit across social, economic, and environmental categories. Overall, this dissertation research provides useful and relevant computer-based tools for water resources planners and managers interested in maximizing hydrological ecosystem services benefits.

Contributions cover the following topics: sound watershed management practices (case studies and examples from various countries including lessons learned from implementation of both successful and deficient management scenarios), decision support tools (such as monitoring, GIS, ecological economics, cost/benefit analysis and decision making models), integrated environmental model applications for management (including watershed, air-shed, coastal, and living resource models), trans-boundary environmental issues (air pollution, climate change, coastal oceans at regional, continental, and global scales) and global watershed sustainability. This multidisciplinary volume will benefit natural and social scientists, engineers, managers and other professionals as well as stakeholders with an interest in water resources and their management.
Download or read book Integrated Modelling of Ecosystem Services and Land Use Change written by Youjia Liang and published by Springer Nature. This book was released on 2019-10-17 with total page 182 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents essential case studies on the integrated modelling of ecosystem services and land-use change in the field of landscape ecology. The case studies were mainly conducted in the Zhangye oasis of the Hexi corridor and the upper reaches of the Heihe river basin, including Loess plateau (for wind power) and the inland waterways of the Yangtze River (for the regulation of extreme events). The book puts forward an integrated modelling method, including human activities, natural processes, land-use change, and ecosystem management, and explores multiple scenarios based on the interests of local managers and their implications for ecosystem services. As the book demonstrates, the integrated modelling method for ecosystem services and land-use change can serve as a valuable tool for gauging the impact of various development scenarios in this study area, and in other regions with similar characteristics. In addition, numerous charts and diagrams are included in each chapter, facilitating the simulation and assessment of specific land-use change impacts on ecosystem services in various study areas.
Download or read book User Modeling and Optimization for Environmental Planning System Design written by Vidya Bhushan Singh and published by . This book was released on 2014 with total page 262 pages. Available in PDF, EPUB and Kindle. Book excerpt: Evironmental planning is very cumbersome work for environmentalists, government agencies like USDA and NRCS, and farmers. There are a number of conflicts and issues involved in such a decision making process. This research is based on the work to provide a common platform for environmental planning called WRESTORE (Watershed Restoration using Spatio-Temporal Optimization of Resources). We have designed a system that can be used to provide the best management practices for environmental planning. A distributed system was designed to combine high performance computing power of clusters/supercomputers in running various environmental model simulations. The system is designed to be a multi-user system just like a multi-user operating system. A number of stakeholders can log-on and run environmental model simulations simultaneously, seamlessly collaborate, and make collective judgments by visualizing their landscapes. In the research, we identified challenges in running such a system and proposed various solutions. One challenge was the lack of fast optimization algorithm. In our research, several algorithms are utilized such as Genetic Algorithm (GA) and Learning Automaton (LA). However, the criticism is that LA has a slow rate of convergence and that both LA and GA have the problem of getting stuck in local optima. We tried to solve the multi-objective problems using LA in batch mode to make the learning faster and accurate. The problems where the evaluation of the fitness functions for optimization is a bottleneck, like running environmental model simulation, evaluation of a number of such models in parallel can give considerable speed-up. In the multi-objective LA, different weight pair solutions were evaluated independently. We created their parallel versions to make them practically faster in computation. Additionally, we extended the parallelism concept with the batch mode learning. Another challenge we faced was in User Modeling. There are a number of User Modeling techniques available. Selection of the best user modeling technique is a hard problem. In this research, we modeled user' preferences and search criteria using an ANN (Artificial Neural Network). Training an ANN with limited data is not always feasible. There are many situations where a simple modeling technique works better if the learning data set is small. We formulated ways to fine tune the ANN in case of limited data and also introduced the concept of Deep Learning in User Modeling for environmental planning system.

Download or read book Developing an Integrated Multi scale Modeling System for Assessing Conservation Benefits in Subsurface Drained Watersheds written by Vinayak Shamrao Shedekar and published by . This book was released on 2016 with total page 295 pages. Available in PDF, EPUB and Kindle. Book excerpt: An integrated modeling framework was developed by linking the relevant features of DRAINMOD-NII, a field scale hydrologic simulation model with SWAT-2005, a watershed scale simulation model. The uncertainty associated with rainfall measurements as an input parameter common to field as well as watershed scale modeling was assessed by conducting static and dynamic calibration of three tipping bucket raingauge models. Rainfall data measured in a subwatershed (B) of the Upper Big Walnut Creek were then corrected using the calibration equations. A sensitivity analysis using uncorrected versus corrected rainfall data showed significant potential biases in model predictions due to errors in rainfall measurements. The second phase of study involved calibration and validation of DRAINMOD-NII for drainage discharge and nitrate (NO3-N) loads from two subsurface drained fields monitored within the watershed-B. DRAINMOD-NII predicted the monthly, seasonal and annual hydrology and NO3-N loads with good accuracy. Effects of drainage water management (DWM) on annual water and NO3-N budgets were predicted fairly well. However, the hydraulic interdependence of the two fields may have affected the nutrient balance, and hence the estimates of reductions. In the third phase, SWAT-2005 was used to simulate hydrology and nitrogen transport at watershed scale. Overall, SWAT significantly under-estimated the stream discharges at daily, monthly and annual scales. The model performance was relatively better for monthly simulations (NSE of 0.64 and R2 value of 0.67). The total watershed yield on annual basis predicted by the model showed a systematic under-estimation, especially during winter and spring months. Nitrate load simulations by SWAT were unsatisfactory at daily, monthly, as well as annual basis (negative NSE values and slope values close to zero). The nitrate loads and concentrations were several folds lower than those observed during the study period. The errors in simulation of nitrate loading were primarily due to the under-estimation of watershed yield, and also likely due to the combined uncertainty associated with management inputs. Overall, SWAT-2005 posed some major limitations for modeling agricultural watersheds dominated by subsurface drainage. The final phase of study involved integrating DRAINMOD-NII with SWAT-2005 in order to facilitate better representation of field-scale processes and management within the watershed. The integrated model helped improve the sub-watershed scale prediction accuracy of SWAT with respect to daily, monthly and annual drainage discharges and nitrate loads. The improvements in drainage discharges were more prominent during wet years than during dryer years. The integrated framework was able to predict more realistic magnitudes and variations of daily, monthly and annual drainage outflows. The nitrate flows were predicted with a greater accuracy by the integrated model, compared to those by SWAT-based approach. The integrated framework may be further used to evaluate the effects of implementation field-scale management practices, such as DWM, sub-irrigation, and waste-water application.
