Evaluating the Interpretation Uncertainty From the Manual Streambank Delineation

River Research and Applications, EarlyView.
ABSTRACT Streambank delineation enables the development of two important parameters: streambank position and channel width. For older aerial images that cannot be easily processed by automatic methods, manual interpretation of streambanks is a necessary task.

Addressing Unwanted Morphodynamic Processes in Re‐Naturalization Projects

River Research and Applications, EarlyView.
ABSTRACT River systems worldwide are undergoing severe ecological and morphological degradation due to prolonged anthropogenic interventions, such as channelization and dam construction, which disrupt sediment continuity and natural flow regimes. In response, river re‐naturalization projects have emerged as essential strategies to restore the dynamics ...

The safe development paradox of the United States regulatory floodplain.

PLoS ONE
In the United States, requirements for flood insurance, development restrictions, and federal buyout program eligibility rely on regulatory designation of hazardous zones, i.e., inside or outside the 100-year floodplain.

Evaluating Movements of Co‐Occurring Silver and Bighead Carp in a Small Missouri River Tributary

River Research and Applications, EarlyView.
ABSTRACT Silver Carp Hypophthalmichthys molitrix and Bighead Carp Hypophthalmichthys nobilis commonly inhabit small tributaries of mainstem rivers. However, dynamic environmental conditions within these systems may influence their movement patterns differently than in larger rivers, potentially leading to important implications regarding their range ...

Relationships among catches, fishing effort and river morphology for eight rivers in Amazonas State (Brazil), during 1976-1978

, 1983
For eight rivers in the Amazonas State (Brazil), it is shown that the annual number of fìshermen and dummy variables, which identify the rivers, explain 98.8 % of the landings at Manaus market.

Change in groundwater chemistry as a consequence of suppression of floods: the case of the Rhine floodplain [PDF]

, 2003
Spatio-temporal variations of nitrogen, phosphorus and base cation concentrations in groundwater were related to the drastic change in hydrological conditions of the Rhine alluvial floodplain (Eastern France), which has been disconnected from the river ...

Long‐Term Effects of Low‐Drop Grade Control Structures on Channel Evolution in the Yazoo River Basin

River Research and Applications, EarlyView.
ABSTRACT Channel incision is a widespread problem, especially in river basins that have an extensive history of channel alterations. Because channel incision causes large ecological and economic consequences, the prevention of continued migration of headcuts, defined as a steep change in stream gradient over a short reach, has been the focus of many ...

Using the Relative Elevation Models to delimit the floodplain level development: The case of the braided-wandering Belá River, Slovakia

Moravian Geographical Reports
The Belá River is a specific submountain river running through the Liptov Basin in the Slovak Carpathians. Its transformation from a braided to a braided-wandering system and degradation including incision of the river system has been observed since the ...
