This course provides guidance on system-wide watershed rehabilitation by introducing advanced concepts in fluvial geomorphology and channel dynamics, along with engineering methods for conducting background assessments and field data investigations, selecting and siting structures, evaluating channel stability, and producing stable channel designs.
The Mississippi Delta Headwaters Project (MDHP), formerly the Demonstration Erosion Control Project, was initiated to address problems related with watershed erosion, sedimentation, flooding, and environmental degradation. The project activities encompass 16 watersheds, ranging in size from 0.5 to 600 miles2 (mi2) in the Yazoo River Basin of northwest Mississippi. The MDHP revolutionized the systems approach to addressing channel stability issues by considering an entire watershed, rather than only local characteristics and problems. A systems approach is critical when identifying and addressing interconnected problems within a watershed. This approach provides a process-based framework to define watershed dynamics and to develop comprehensive solutions, with widespread applicability in various fluvial environments. The Advanced Streambank Protection course incorporates classroom and streamside lectures within the MDHP area, providing a unique learning environment. The MDHP covers 2630 mi2, making it one of the nation’s largest watershed rehabilitation projects. The analysis tools and structural techniques developed here have been used in all parts of the country. Utilizing a group of nationally recognized instructors, students will participate in a series of half- and full-day field trips to investigate a wide array of stream types within a 50 mile radius of Grenada, Mississippi. Classroom lectures will cover state-of-the-industry protection techniques, watershed dynamics (sediment and hydraulic), and prediction methods in watershed management (i.e., Sediment Impact Analysis Methods (SIAM)). Over 25 streamside interactive mini-lectures will be conducted with subjects including: identifying dominant hydraulic, geotechnical, and morphological processes; bed gradation sampling methods; analysis of riparian vegetation and hydraulic impacts; and the role of vegetation in bank protection. The long-term performance (hydraulic, geotechnical, and environmental) and effectiveness of several grade control and streambank protection projects will be analyzed. Some projects are over 30 years old. Some failed sites will be reviewed. Repair or redesign and replacement of these projects will be discussed. Using advanced geomorphic analysis techniques, several severe bank erosion and bed degradation sites will be reviewed from both a local and system-wide perspective. For these sites, project goals will be formulated and conceptual designs developed. In-class discussion will focus on further review of completed projects, failures, and erosion problems studied during the field trips. Students are encouraged to give a brief presentation of a current project for group discussion and review.
It is recommended (but not required) that the student first complete the Streambank Erosion and Protection course (#285). The target audience for this course is employees in (a) Occupational Series: 0000-0100, 0400, 0800, 1300, and (b) Grade GS-07 or above, but the course is open to employees in any grade or occupational series.
