Dedicated IT infrastructure for Smart Levee Monitoring and Flood Decision Support

Abstract

Abstract. Smart levees are being increasingly investigated as a flood protection technology. However, in large-scale emergency situations, a flood decision support system may need to collect and process data from hundreds of kilometers of smart levees; such a scenario requires a resilient and scalable IT infrastructure, capable of providing urgent computing services in order to perform frequent data analyses required in decision making, and deliver their results in a timely fashion. We present the ISMOP IT infrastructure for smart levee monitoring, designed to support decision making in large-scale emergency situations. Most existing approaches to urgent computing services in decision support systems dealing with natural disasters focus on delivering quality of service for individual, isolated subsystems of the IT infrastructure (such as computing, storage, or data transmission). We propose a holistic approach to dynamic system management during both urgent (emergency) and normal (non-emergency) operation. In this approach, we introduce a Holistic Computing Controller which calculates and deploys a globally optimal configuration for the entire IT infrastructure, based on cost-of-operation and quality-of-service (QoS) requirements of individual IT subsystems, expressed in the form of Service Level Agreements (SLAs). Our approach leads to improved configuration settings and, consequently, better fulfilment of the system's cost and QoS requirements than would have otherwise been possible had the configuration of all subsystems been managed in isolation.

Smart Levee in Poland. Full-Scale Monitoring Experimental Study of Levees by Different Methods

“…Based on further analyses where the availability of the sensor chips and costs of purchase and other associated with the application in the measuring constructions was concerned, it was decided to implement widely-used digital temperature sensors (DS18B20), which present sufficient sensitivity defined as the resolution and accuracy of the measurements (Table 4). accuracy (1) Typical/max ±0.5 • C/±0.5 • C price e 1.00 availability (2) high (1) In range being the subject of analysis; i.e., from −5 • C to 30 • C.…”

“…Furthermore, it realizes self-testing procedures. • Edge Node (EN) -equipped with a communication module and a radio subsystem to communicate with the MNs in its section and equipped with an RS232/RS485 interface for the Modbus protocol [19] used to transfer the aggregated measurement data to the ISMOP central analytical system [2]. The Edge node's role is network management and monitoring, management of measurement scenarios, verification and qualification of data, data transfer, and realization of diagnostic procedures of its internal modules and "subordinate" MNs.…”

Detection of seepages and monitoring of structural changes in earthen embankments by FO DTS

“…On the Rhine dam, real seepage flows were monitored using the FO DTS systems. Research teams from AGH University of Science and Technology in Cracow are dealing with further installations and data evaluations from FO DTS systems on a research polygon (Dwornik, et al, 2016) (Balisa, et al, 2016).…”

The continuous thermal imaging of the flood embankment to identify location of the leaks

“…Several flood experiments have been conducted. The experimental embankment was equipped with optical fiber as well as with a distributed sensor system inside the shaft, and two weather stations [2,3]. Additionally, other external measurements were carried out, like: surveying, geoelectrical sounding and profiling, thermographical and hyperspectral monitoring.…”
