12 Classify river geomorphology by longitudinal changes (i.e. Kearney downstream vs. upstream)
13 Develop classification system for Platte bridge /diversion reaches
14 Compile GIS coverages, indices of geomorphic aspects by classes
15 Prepare summaries of Platte geomorphologic features
16 Evaluation of data on sand bars vs. islands as habitat re: definition criteria including unobstructed
17 Develop correlations of geomorphic features with possible causes
18 Correlation of form with slope, soils, grain size, Q, etc.
19 Verify correlations in literature (i.e., Lane's Law, Rubey's Corollary)
20 Correlate channel features with man -made vs. natural causes
21 Prepare report - "Comprehensive Geomorphic Assessment of the Central Platte River"
D. Coordination with Other River Process Investigations
1 Jointly establish geomorphological data collection and analysis methodology protocols
2 Meetings, discussions, other geomorphologic communication with other investigators
3 Ongoing geomorphic interpretations
E. Geomorphic Interpretation through Three Level Approach
1 Qualitative Interpretation - Summarize qualitative geomorphic information from this assessment
with investigations and relate to system -wide effectiveness, potential adverse consequences, and
Iona -term sustainability.
2 Quantitative Interpretation - Summarize quantitative analyses from investigations related to
potential restoration activities regarding system -wide effectiveness, potential adverse
conseauences. and Iona -term sustainabilitv.
3 Linked Process Modeling - Design model tests, make model runs, and interpret model runs
including various flow /management scenarios, hydrologic scenarios (including drought
assessment), and trade -offs among potential management activities to
evaluate the system -wide geomorphic effectiveness, potential adverse consequences, and long-
term geomorphic sustainability. Note: It is important to consider that the results of short -term
investigations in the initial portion of the first increment
(along with preceeding available data and information) are limited by the hydrologic conditions over
these few short years and probably do not consider the appropriate range in variability in hydrology
that must be factored into
an evaluation of long -term sustainability issues. These long -term questions can be addressed
through the modeling effort, which can incorporate a wider range of hydrologic conditions than
encountered during the other investigations.
F. Reporting
1 Interim presentations (4 /year)
2 Draft reports (1 /year)
3 Final report of Tasks A through C (Specific Geomorpholoqic Data Collection and Analysis)
4 Review, discussion, evaluation, and executive summary documentation of Task D through E,
including geomorphic interpretations of Tasks A to C with all investigations (multi- disciplinary
