| Abstract: | The Kansas River is an important water resource in Kansas. Like most major rivers, the Kansas River has undergone significant changes, both natural and anthropogenic, over the past century, with potential implications for water supply, hydropower, flooding, recreation, and environmental resource management. The purpose of this study is to analyze hydrologic and geomorphic changes on the Kansas River from 1985 – 2009. An analysis of the hydrology, sediment transport, and channel morphology for the period of time prior to 1985 can be found in Analysis of Channel Degradation and Bank Erosion in the Lower Kansas River (Simons, Li, and Associates—hereafter SLA 1984). An in‐depth look at the geology and economic impact of the Kansas River can be found in Brady et al. (1998). This study addresses the following questions: 1. Has the flow volume and flow‐duration structure of the Kansas River changed? 2. What are the hydrologic impacts of the federal reservoirs? 3. How are the stage‐discharge relationships changing? 4. Did the floods of 1993 and 2007 alter the stage‐discharge relationships? 5. Where is the Kansas River degrading, aggrading, or remaining stable? 6. Where is the Kansas River widening, narrowing, or unchanging? 7. Can morphological changes on the Kansas River be correlated to dredging activities? This report is divided into five sections. Section 1 contains this introduction. Section 2 presents a hydrologic assessment of the Kansas River, including an assessment of flow volumes and the flow‐duration structure of the river at five gaged locations. Section 3 presents a geomorphic assessment of the river, including qualitative descriptions based on field reconnaissance, aerial photography, and various published resource, and quantitative analyses based on changes in stage‐discharge relationships and measured cross‐sections. Section 4 discusses dredging and analyzes influence on current channel changes. Section 5 presents the conclusion. |
