A Methodology and ArcView Tools for Predicting Channel Migration
نویسندگان
چکیده
At present, no practical methodology exists for routine prediction of stream meander migration and uncertainty concerning the level of risk to infrastructure remains unacceptably high. This paper describes a Handbook that includes ArcView 3.2-based Bend Measurement and Channel Migration Predictor extensions, which provides a practical methodology to transportation engineers, floodplain managers, planners, developers, geographers, etc. to predict the rate and extent of meander migration through the use of sequential historic aerial photographs and maps. Results of a recent Beta test by highway hydraulic engineers and watershed planners indicates that the methodology will provide valuable analytical and planning tools to practitioners.

Floodplain mapping using HEC-RAS and GIS in semi-arid regions of Iran
Abstract A significant deficiency of most computer models used for stream floodplain analysis is that the locations of structures impacted by floodwaters, such as bridges, roads, and buildings, cannot be effectively compared to the floodplain location. This research presents a straightforward approach for processing output of the HEC-RAS hydraulic model, to enable two- and three dimensional f...
متن کاملDeveloping GIS Tools to Integrate MCDM Models for the Analysis of Bank Branch Closures
In this research, MCDM methods have been integrated with a GIS to provide the means to prioritise branch closure procedures based upon a variety of different choice criteria and on the importance (weight) a decision maker might attach to these. Both MCDM and GIS are well established methods and fields of research. Their integration, however, seems at best an emerging field. This paper describes...
