“…Water surface drifting buoys have been proposed as a possible tool to facilitate the collection of hydrological information in rivers and riverine environments [12][13][14][15][16]. Water surface drifting buoys (hereafter referred to simply as "drifters") are floating bodies equipped with sensors and/or communication systems that passively follow the movements of water surfaces, collecting information about their movement and/or their surrounding environment.…”

“…The use of drifters has produced promising results in river research (Table 1). For instance, [11] shows the use of a GPS-based drifter for flow and velocity characterization in a river, [12] demonstrates the possibility of inferring dispersion and diffusivity of particles in rivers, [16] shows their use for estimating water surface roughness and [14] their capability to improve modeling by using the collected information for data assimilation. Despite the promising published results, drifter technology has not been established as an indispensable tool in the study of rivers.…”

The continuous observation of flows is required to assess a river’s ecological status, to allocate irrigation withdrawals, to provide sustainable hydropower production and to plan actions as well as develop adaptive management plans. Drifters have the potential of facilitating the monitoring and modeling of river behavior at a fraction of traditional monitoring costs. They are floating objects equipped with sensors able to passively follow the movements of water. During their travel, they collect and transmit information about their movement and their surrounding environment. In this paper, we present and assess a low-cost (<150 EUR) customizable drifter developed with off-the-shelf components. The open drifter is capable of handling the majority of use cases defined in the specialized literature and in addition it offers a general river flow characterization toolkit. One of the main goals of this work is to establish an open hardware and software basis to increase the use of drifters in river studies. Results show that the proposed drifter provides reliable surface velocity estimates when compared to a commercial flow meter, offering a lower cost per data point and in contrast to traditional point measurements it can be used to identify and classify large-scale surface flow patterns. The diverse sensor payload of the open drifter presented in this work makes it a new and unique tool for autonomous river characterization.

“…We aim to propagate the variance/covariance matrix Σ δ χ through the geolocation equation. Unfortunately, the variance/covariance propagation law only applies to linear transformations 1 , we need to linearize equation (2). Linearization of (2) around the measurement vector χ 0 is nothing else than the Taylor expansion of X n around χ 0 :…”

This paper describes the performance analysis of an autonomous drifting buoy equipped with a GNSS receiver, an inertial measurement unit and a single beam echosounder. The system is intended for surveying difficult access areas like high-flowing rivers, confined zones and ultra shallow waters, which are unreachable using a classical survey launches. Thanks to a total propagated uncertainty analysis, we show that the system meets international and industrial hydrographic standards.
