In the USA, the US Army Corps of Engineers has jurisdiction over waterways. Notification of the Corps is required under Section 404 of the Clean Water Act, even for rearranging rocks in a streambed. They can help direct you as to what, if any, permitting is required.
Floods
Published in Saeid Eslamian, Faezeh Eslamian, Flood Handbook, 2022
By the end of the 20th century, the concept of flood risk management had been widely accepted in Europe and was beginning to take hold in the United States [31]. The waterways of the United States are managed by the US Army Corps of Engineers (USACE). USACE began to develop an approach to using modern risk concepts in the evaluation of flood management projects in the early 1990s. In 1996, the agency published its first formal engineering manual on risk: Risk-Based Analysis for Flood Damage Reduction Studies [41]. This manual describes how the risk concepts would be used in USACE flood damage reduction studies in the conduct of hydrologic, hydraulic, geotechnical, and other analyses. The manual became the standard for conducting hydrologic and hydraulic analyses for planning studies but was not adopted by the geotechnical and other communities within USACE. In 2000, USACE issued the engineering manual Design and Construction of Levees to promulgate the basic principles that should be used in the design and construction of levees [42]. That manual noted the use of a risk-based approach in hydrologic and hydraulic design, but indicated that geotechnical design would continue to use deterministic methods.

During drought periods many prairie potholes are expected to dry up more frequently or earlier in the spring. This will lead to a decline in breeding habitat for waterfowl, and declines in other wetland species as well. However, predicted increases in large precipitation events may also lead to increased flooding as well as sediment, nutrient and chemical loading in our waterways.

The city is the fastest-growing environment on Earth: over half of humanity currently lives in urban areas, and that number is only expected to increase (United Nations, 2014). However, the rapid pace of development comes with a high environmental cost. In paving large areas of land and removing tree canopy and vegetative cover, humans have effectively shifted the local water balance from a system that is primarily driven by infiltration and evapotranspiration to one that is dominated by runoff (Strassler et al., 1999). The result is increased flooding and significant water quality challenges, as runoff picks up contaminants from streets and lawns and transports them into local waterways (Strassler et al., 1999). This impact is already evident in cities around the United States, such as the Washington, D.C. area and the surrounding Anacostia River watershed. As a result of rapid urban development, the annual frequency of moderate flooding on the Anacostia River tripled between 1940 and 1990 (Konrad, 2016).
A Heuristic Approach to Managing Inland Waterway Disruption
Published in Engineering Management Journal, 2021

As shown in Exhibit 1, inland waterway transportation faces natural and man-made events resulting in significant economic losses and infrastructure damage. The frequency of common inland waterway disruptions such as droughts and floods is expected to increase as a result of climate change (Edenhofer et al., 2014). Given the significant impacts of inland waterways disruptions, increased expected frequency of natural disruptions, inland waterways system benefits in comparison to other transportation modes, and the waterways’ contributions to the U.S. economy, investigating pre- and post-disruption responses to support inland waterways is crucial to maintaining a reliable transportation system. Next, we discuss the contributions of our research and provide recent literature classified into three topics relevant to our research: inland waterway disruption response, cargo prioritization, and berth allocation problem.
The effects of check dams on the amount and pattern of flood

Changes in hydrological processes due to changes in waterway profile will have significant effects on the quantity of runoff from the basin. The purpose of this study is to investigate the changes caused by the construction of check dams on the amount and pattern of flow in a waterway using field measurements, spatial information, and hydrological modeling. In addition to validating the HEC-RAS model in estimating the flow pattern in waterways, the results of this research can be used by researchers and watershed management engineers to determine the effectiveness of check dams in the waterways.
