Book Synopsis Landscape Erosion and Evolution Modeling by : Russell S. Harmon
Download or read book Landscape Erosion and Evolution Modeling written by Russell S. Harmon and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 120 pages. Available in PDF, EPUB and Kindle. Book excerpt: Landscapes are characterized by a wide variation, both spatially and temporally, of tolerance and response to natural processes and anthropogenic stress. These tolerances and responses can be analyzed through individual landscape parameters, such as soils, vegetation, water, etc., or holistically through ecosystem or watershed studies. However, such approaches are both time consuming and costly. Soil erosion and landscape evolution modeling provide a simulation environment in which both the short- and long-term consequences of land-use activities and alternative land use strategies can be compared and evaluated. Such models provide the foundation for the development of land management decision support systems. Landscape Erosion and Evolution Modeling is a state-of-the-art, interdisciplinary volume addressing the broad theme of soil erosion and landscape evolution modeling from different philosophical and technical approaches, ranging from those developed from considerations of first-principle soil/water physics and mechanics to those developed empirically according to sets of behavioral or empirical rules deriving from field observations and measurements. The validation and calibration of models through field studies is also included. This volume will be essential reading for researchers in earth, environmental and ecosystem sciences, hydrology, civil engineering, forestry, soil science, agriculture and climate change studies. In addition, it will have direct relevance to the public and private land management communities.

MODELLING SOIL EROSION BY WATER l 2 John Boardman and David Favis-Mortlock 1 School of Geography and Environmental Change Unit Mansfield Road University of Oxford Oxford OX1 3TB UK 2 Environmental Change Unit University of Oxford 5 South Parks Road Oxford OX1 3UB UK Introduction This volume is the Proceedings of the NATO Advanced Research Workshop 'Global Change: Modelling Soil Erosion by Water', which was held on II-14th September 1995, at the University of Oxford, UK. The meeting was also one of a series organised by the IGBP 1 GCTE Soil Erosion Network, which is a component of GCTE's Land Degradation Task (3.3.2) (Ingram et aI., 1996; Valentin, this volume). One aim of the GCTE Soil Erosion Network is to evaluate the suitability of existing soil erosion models for predicting the possible impacts of global change upon soil erosion. Due to the wide range of erosion models currently, in use or under development, it was decided to evaluate models in the following sequence Favis-Mortlock et al., 1996): • field-scale water erosion models • catchmenr-scale water erosion models • wind erosion models • models with a landscape-scale and larger focus. As part of this strategy, the first stage of the GCTE validation of field-scale erosion models was carried out at the Oxford NATO-ARW. I A list of Acronyms fonns Appendix A.

Book Synopsis Modeling Critical Source Areas of Water Erosion to Inform Soil Conservation by : Ames Francis Fowler
Download or read book Modeling Critical Source Areas of Water Erosion to Inform Soil Conservation written by Ames Francis Fowler and published by . This book was released on 2021 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Effective treatment of persistent agricultural erosion with limited conservation funds requires the identification of critical source areas (CSA) at the subfield scale for watershed scale planning. Publicly available data, physically-based modeling frameworks, and strong conservation district initiatives are now all in place to more directly connect conservation implementation with the underlying physical hydrology. The overall objective of this dissertation was to operationalize physical modeling simulations to identify CSA and inform strategic conservation prioritization. I developed a method for spatially distributing a simplified framework of the Water Erosion Prediction Project (WEPP) model that simulates the physical mechanisms of hillslope hydrology and erosion. A land type characterization of representative WEPP profiles was defined for spatial slope, soil, climate, and management data. Profile simulations mapped to individual flow paths in a regional watershed. This method preserved a higher resolution than the WEPP hillslope approach at 95.6% less computational cost. Simulating multiple conservation practice scenarios identified CSA at the subfield scale as well as conservation practice effectiveness. Erosion decreased by 58% for a change from uniform conventional tillage (CT) to mulch tillage (MT) and by 98% for CT to no-tillage (NT). Treatment of 25% of agricultural area effectively accounted for almost all of this reduction in erosion. Ten-meter conservation buffers were highly effective at reducing sediment delivery to the stream where erosion rates were large.With a voluntary conservation paradigm, identifying CSA is insufficient to promote good conservation. Historically, social and financial drivers of conservation adoption have buffered implementation. A system dynamics model simulated the physical, social, and financial incentive interactions to understand conservation adoption and erosion rates under possible conservation targeting scenarios. Targeting CSA with conservation funding for land retirement with the conservation reserve program and for reduced tillage decreased the total average erosion rate by more than 50%. The most effective use of conservation funds, however, occurs when the diffusion of innovation mechanism is reinforced by broad-scale payments for tillage reduction. By identifying positive feedback, our simulations suggest large potential gains in erosion reduction and conservation fund efficiency are possible. Findings from this work can greatly enhance soil and water conservation planning.
