Experience of the pilotless aircrafts application for decision of tasks connected with surface water bodies’ bank stripe condition and dynamics assessment has been discussed. In order to increase substantially the survey and subsequent estimations accurancy the use of reference points (markers) has been proposed, with determining of the plane and altitude coordinates with professional two-frequency GPS-GLONASS recievers in accordance with the standing regulating documants. This approach will enable to improve drastically quality of the obtained assessments and efficiency of the pilotless aircraft application. Analysis of the slope reforming intensity has been carried out at the range of the Kosva River right bank in the vicinity of the villige of Peremskoye on the basis of the 2017 field investigations outcomes. Such estimations are necessary for effective forecasting of bank changes dynamics, as well as for designing of any bank protection measures.

The river Lutz as many other rivers in Austria was forced into a straight and narrow river bed. Several weirs were erected to stabilise the river bed, but which, too, impeded organism passability. After decades with several floods the protection measures were in bad condition. In 2005, a 500-years flood caused heavy damage along the river and destroyed a main railway line. This incident initiated comprehensive planning activities to improve both, the flood protection as well as the ecological status of the river. Several technical measures focussing on stabilising the river bed, increasing the discharge capacity and improving the ecological status such as a step-pool-ramp with variable width, an open rip-rap, an increased river width as well as embankment groynes as an ecological and dynamic bank protection instead of a bank reinforcement were proposed. These measures were tested for feasibility and optimized in a physical model experiment.

The Imeretinsky lowland – the central fragment of a large Black Sea terrace of the Caucasian coast of Russia, is located in interfluve the rivers Mzymty and Psou. In its central and western part large sports complexes of the winter Olympic Games "Sochi-2014" and the Olympic village are under construction. It has led to necessity of engineering protection of coast from the constructed port Imeretinsky to east board of cape of Konstantinovsky. In the report the site located from the Southern pier of port to the western board of cape of Konstantinovsky is considered. On a site the underwater canyon Novuy is located. To provide stability of a shore, the project of coastal protection now is realized. This project provides building in a surface part of a beach ferroconcrete grille on piles and a slope from concrete cubes. Before should be fill an artificial pebble beach in width not less than 50 m. As has shown inspection of coastal protection constructions, rates a beach lag behind rates of its washout. The width of a surface beach makes now no more than 13 m. For scoping executed embankments sandy a material comparison bathymetric shootings before port building (2007) has been made and April, 2012. By comparison is established that slept pebble the material is at the bottom and doesn't move waves on coast. Thus, massed filling the pebble material, coasts of Imeretinsky lowland spent recently on a considered site, haven't led to formation of a steady surface beach in design width of 50 m. On this site, and also on a site around Konstantinovsky's canyon updating of design decisions is required.

Material Erosion

<p>Riverbank erosion is a ubiquitous, natural process. Typically, it occurs during larger flood events when the applied forces exerted by the flowing water on a bank exceed some erosion-resistance threshold. Riverbank protection may be needed when critical infrastructure is present or planned near eroding banks, which requires the quantification of the risk of infrastructure failure by bank erosion. Similarly, renaturalization of many European streams, for example through removal of bank protection measures, necessitates the quantification of expected river width adjustment. Unfortunately, we have been unable to accurately quantify bank erosion rates to date. Limitations exist in characterizing both the applied and resisting forces. For example, bank roughness co-evolves with erosion, which makes it difficult to adequately resolve the forces acting on the bank material. Bank material erosion-resistance of fine-grained soils varies significantly, that is over orders of magnitude, both spatially and temporally. Moreover, existing techniques to measure bank material erosion-resistance do not always produce repeatable results. As a consequence, existing bank erosion models, such as the widely used Bank Stability and Toe Erosion Model (BSTEM), require extensive calibration and validation. This is often unsatisfactory to river engineering professionals that have to make decisions on where to place bank protection measures and the level of protection required. The decision-making process could benefit from a risk-based analysis that quantifies the uncertainty in calculated bank retreat rate. Recent enhancements to the BSTEM model allow users to input probability density functions of (measured) bank roughness and bank material erosion-resistance properties. A Monte Carlo analysis then quantifies the effects of both variability and uncertainty in these parameters on bank retreat. We will present how the shape of different probability density functions affect the probability density function of bank retreat. Results will be further presented of application of the new model to assist in prioritizing riverbank restoration measures along the Lower American and Sacramento Rivers, CA, USA, to prevent failure of levees that protect the City of Sacramento from flooding.</p>
