“…Hydraulic resistance is a key problem of both technical and river hydraulics. On their basis, calculations of various parameters of channel flows and fragments of hydraulic structures are performed [2]. Taking into account the dependence of channel processes on the position of rivers in geographic zones, landscape and climatic conditions is of particular importance.…”

“…On their basis, calculations of various parameters of channel flows and elements of hydraulic structures are performed. At the present stage of development of science and technology, the need to improve the reliability of such calculations is of particular relevance due to the increasing scale of landscape ecology control and the implementation of a monitoring system for water bodies [1], including using autonomous vessels [2]. Increasingly, digital models of the seabed relief are being built [3], including using satellite altimetric observations [4], modeling of complex underwater landscapes in order to more accurately predict the erosion and destruction of hydraulic structures [5], and the degree of influence of plant roots [6][7][8] on morphodynamics is estimated.…”

The paper is devoted to the analysis of modern problems in assessment of hydraulic resistance. The obtained formulas for calculating the roughness coefficients and other interrelated hydraulic parameters of the channel are given. As a determining factor for the systemic characteristics of flows, N.A. Rzhanitsyn used the average long-term and average maximum water discharges, and the authors of this work proposed the use of these characteristics in accordance with the watershed area A in km2 of the subsequently derived dependences for unexplored rivers. Thanks to this approach, it became possible to obtain information by cartographic methods. Direct approximation of these data gives an expression for the flow order. The formulas obtained can be used to calculate the hydraulic characteristics of lowland rivers. For the European territory of Russia, the formulas have been tested using independent field information. However, the authors believe that the formulas will successfully work for other even lands as well. The formulas are simple and easy to calculate using software. In the future, it is planned to use specialized software for processing calculations and use the obtained results in the geographic information system.

“…[1,2] In parallel, modern advances in science and technology allow the construction of highly automated vessels. They reduce or eliminate the role of the ship's crew and enable the implementation of remotecontrolled or autonomous modes of operation [3][4][5]. This requires the building of a concept, methodological foundations, mathematical models and scenarios that will serve as the foundation for the development of the geographical information system software.…”

The current level of technology in terms of instruments, devices and software enables the construction of local intelligent transport systems that contribute to the prevention of accidents. It has become possible to build crewless and unmanned vessels. Geographical information services such as Google Maps, Mapbox, OpenStreetMap have already shown their effectiveness. The relevance of the study stems from the possibility to partially automate ship’s route planning nowadays. As navigation monitoring is carried out by means of VHF (very high frequency) - Automatic Identification System (AIS) receivers, the authors propose to collect and analyse data. However, for the construction of the geographical information system and data processing, the authors justified the proposal to build the concept, methodological foundations, mathematical models and scenarios, which will serve as the basis for the development of software for the geographical information system. They propose data types for constructing time/speed matrices for planning optimal routes based on the current navigational situation. The data collected will provide a 12-36 hour forecast and allow for the determination of vessel speeds and times, considering vessel specifications, traffic of other vessels, queue at locks, forecast of hydro- and meteorological conditions, estimates of traffic intensity and density. The service is expected to optimise the route in terms of speed and journey time to meet the transport and logistics challenge.
