Purpose
To coordinate and provide local level support in the process of mapping of targeted micro location, preparing methodological guidelines for establishment, developing technical specification for data acquisition and measuring devices, and developing system specifications for the data acquisition, distribution and early warning software at the second order water sources in Drina River Basin.
Objective
To support the implementation of the Mapping of confluences of second-order water streams on selected micro-location in Drina River Basin, Project.
Background Information
The floods represent one of the most prominent risks in Serbia and the examples of adverse events in the period 2014-2020 show floods simultaneously hit at least three LSGs (Local Self Governments) and affecting large part of the populated areas, with imminent exposure risks of landslides and erosions. As the Second Report of the Republic of Serbia to the UN Framework Convention points out, the disaster risk level recorded in 2014 will be increased by 7% in the next 30 years, increasing damages on critical infrastructure and related influence on human lives and health, and the overall economic activity and stability.
The Drina River Basin covers a territory of 20,320 km² shared by the Republic of Serbia, Bosnia and Herzegovina and the Republic of Montenegro, while 1% of the territory belongs to the Republic of Albania. The Serbian share of the Drina River Basin covers the territory of 11 local administrations. Inhabited with approximately 300,000 people.
Drina River Basin Cooperation municipalities are highly exposed to torrential floods of second-order water streams which are under the jurisdiction of local governments. According to Risk Assessment Documents 10 out of 11 participating municipalities are in a high risk of flash floods. Furthermore, the 5 out 11 participating municipalities (Bogatic, Loznica, Krupanj, Mali Zvornik and Ljubovija) are particularly exposed and vulnerable to the torrential floods. Since 2010, an Emergency Situation in Drina River basin caused by the second order torrential floods was declared 6 times.
Since 2010, damages in Drina River Basin caused by floods and reciprocal landslides have exceeded USD 82 million (excluding loses). More than 70% of the previously mentioned damages were caused by the second order flash floods. The real damage are much higher than recorded due to (i) lack of relevant information pertaining to second order water streams; (ii) protocols associated with the declaration of an untoward emergent event; and (iii) application of the outdated damage assessment methodology. Moreover, flash floods affect the most vulnerable locations at least twice a year (every spring and autumn). However, these damages are not being recorded unless emergency situation is declared by local authorities.
Flood prevention and early warning system is based on the data acquired from 11 measuring stations placed on the first order water streams maintained and monitored by Public Water Management Company ‘Srbijavode’. However, when it comes to the locally managed waters municipal administrations do not possess accurate records of rivers and water streams in their respective territory. Therefore, the first step in establishing an early warning system would include spatial, plant cover, soil composition, and urban infrastructure mapping on targeted locations. Collected information coupled with data of identified water streams, their length, tributaries, attributable water capacities and susceptibility of the terrain will provide accurate information on exact location for instalment of measuring stations and optimal number of devices.
Secondly, the second order water streams are not covered with data acquisition devices nor measuring stations leaving local administration no possibility to monitor, predict or timely implement preventive measures in affected locations. Therefore, there is a dire need for placement of three types of measuring stations for collecting data on rainfall quantity, soil humidity and water level. Synthesis of acquired data shall enable predicting the appearance of torrential floods in designated micro-locations.
Third, for the purpose of data analysis there is a need for development of data collection, early warning and data exchange system at the local administration level with the prospect for integration along and between the river basins and with the national early warning system.
To support local authorities of the Drina River Basin in addressing above mention challenges, Disaster Risk Reduction & Recovery for Building Resilience, Crisis Bureau – UNDP extended the undertaking procurement action to UNDP Serbia for Mapping of confluences of second-order water streams on selected micro-location in Drina River Basin, Republic of Serbia.
UNDP shall engage consultants for mapping the targeted micro location, preparing guidelines for establishment of early warning systems at the second order water sources, developing technical specification for data acquisition and measuring devices, and developing system specifications for the data acquisition, distribution and early warning software, as well as a consultant to coordinate and monitor the entire process.
