TL;DR: In this paper, the authors describe the phenomena and the damage in the area of the Nyabage River and some proposals for improvements are given, which is a mixture of water and debris and causes severe damage.
Abstract: Occasional flows of the river Nyabage cause floods in the river valley, flooding bridges and buildings, amongst others a small hospital of MsF. The flow is a mixture of water and debris and causes severe damage. The report describes the phenomena and the damage in the area. Some proposals for improvements are given

TL;DR: The US Army Corps of Engineers (USACE) has conducted numerous potamology studies dating from the 1800s to modern times as mentioned in this paper, including the first official USACE Potamology Investigations that resulted in more than 70 reports.
Abstract: The Mississippi River and Tributaries (MR&T) Project is a comprehensive water resources project for flood damage reduction and navigation improvement on the Mississippi River. MR&T elements include levees, floodways, diversion structures, tributary basin improvements, and channel improvements such as meander cutoffs, bank stabilization, dikes and dredging. Understanding how these elements, combined with natural factors, such as floods and droughts, impact the historical, current, and future river morphology is a complex challenge for those tasked with managing the Mississippi River for floods, navigation, environmental restoration, and coastal wetland loss. Mississippi River potamology (the science of rivers) studies advance understanding of how natural and man-made factors combine to impact river morphology regarding present and future flood damage reduction, navigation, environmental restoration, and coastal wetland projects. The US Army Corps of Engineers (USACE) has conducted numerous potamology studies dating from the 1800s to modern times. Major studies were often the result of floods and follow-on beneficial projects. The epic 1927 flood fostered the first official USACE Potamology Investigations that resulted in more than 70 reports. The 1973 flood drove additional USACE potamology studies (T-1 and P-1 reports). However, funding, staffing, and interest in potamology studies waned, becoming almost nonexistent in recent times. Lessons learned and projects implemented from USACE’s 1940s–1980s potamology studies helped pass the recordsetting 2011 flows. The 2011 Mississippi River flood renewed interest in potamology, resulting in the creation of the USACE Mississippi Valley Division’s (MVD) new Mississippi River Geomorphology and Potamology (MRG&P) Program. The first report of the MRG&P was a review of the Lower Mississippi River Potamology Program, including a comprehensive bibliography of potamology reports (Biedenharn et al., 2014). This paper provides a short review of USACE Mississippi River potamology studies.

TL;DR: In this article, two sets of tests were performed (dire and fine-grained) to detect riverbank erosion in a natural river process that threatens the security of instream structures as well as public and private property.
Abstract: Riverbank erosion is a common natural river process that threatens the security of instream structures, as well as public and private property. In this study, two sets of tests were performed (dire...

TL;DR: In this article, a 1:100 scale model of an 8 km stretch of the river Isere through Grenoble was designed and run in accordance with Froude similarity laws.
Abstract: The river Isere winds its way down the Gresivaudan valley to Grenoble and intersects a cross-valley at Voreppe just after leaving the city. A number of river training schemes have been implemented since the mid-nineteenth century (e.g. canalisation and bank protection works), which were governed by "liberal" policies along the river above the city and a more "directorial" outlook downstream, in accordance with prevailing tendencies at the various times they were put into effect. Major bend-cutting and dyke reinforcement work has been carried out since the middle of the twentieth century, including correction of the river's longitudinal profile, some sections of which were tending to build up by sediment deposition, whilst gravel extraction from others was unduly increasing their depth. Work has just started on irnplementation of a new river flood protection programme for Grenoble. Because of considerable past and predicted river bed level variations, this programme has required more detailed research and testing than earlier schemes, which has involved fresh determination of water levels associated with the predicted rates of river flow, up to and including for the hundred-year peak flood discharge. For the necessary tests, a 1:100 scale model of an 8 km stretch of the river Isere through Grenoble was designed and run in accordance with Froude similarity laws. In addition, a mathematical model of the part of the Isere from its confluence with the river Arc to the sill at Saint Gervais, i.e. about 80 km in length, was subsequently designed and operated. In designing this model, several very complicated computer calculations had to be carried out. In addition to dyke protection and provision of a channel down the middle of the river bed, a number of sub-river sills are to be installed as a means of stabilising the river and its aquifers. Preservation of present flood areas to attenuate major flood peaks above Grenoble is also being envisaged. In view of the highly complex problems involved on both horizontal and longitudinal scales, the physical and mathematical models in use for the study are invaluable assets as regards accurate prediction of data for present and future river engineering projects.

TL;DR: In this paper, the authors used Monte Carlo type simulations to predict the erodible corridor width of a reach of the River Irwell, UK, taking into account the uncertainty that arises from input parameters such as representative discharge, channel width, sediment and so on.
Abstract: This paper considers the erodible river corridor, which is the area in which the main river channel is free to migrate over a period of time. Due to growing anthropogenic pressure, predicting the corridor width has become increasingly important for the planning of development along rivers. Several approaches can be used to predict the future erodible corridor width but the results possess a large degree of uncertainty in all cases. The work presented here addresses prediction of the erodible corridor width of a reach of the River Irwell, UK, taking into account the uncertainty that arises from input parameters such as representative discharge, channel width, sediment and so on. The work adopts a probabilistic framework for assessment using Monte Carlo type simulations. Future river corridor width predictions, based on a model calibrated on past observations, are presented in a probabilistic manner using confidence levels. The results indicate the necessity of capturing input variability in the modelling process. Furthermore, the understanding gained from a relatively simple model used in a probabilistic framework is greater than a more complex one where only a few runs are feasible.
