Imperfections of the water management mechanism in the Isfara small transboundary river basin

Until today, hydrometric revolver meters (GR-21) with propeller blade and contact mechanism are generally used.  These mechanisms are difficult to operate and require special skills and knowledge on behalf of personnel.  GR-21 hydrometric revolver meters possess certain essential flaws, including the following:

• need for individual calibration (speed) execution and subsequent check-up of which requires an expensive test stand;
• lack of continuous measuring capacity;
• operating requires complete dismantling, cleaning and lubrication after each use, etc.;
• presence of mechanically rubbing details in design unprotected from harmful effects of water;
• impromptness of water speed (current) data.

The principle of stakeholder engagement in decision-making associated with water management of small transboundary river;

IWRM planning technique

Electronic Water Current Meter (ISV-1)

The river originates in Kyrgyzstan in Ak-Suu Glacier on the northern slope of the Turkestan Ridge 3,193 m above sea level.  The Ak-Suu ruins are located close to the river source.  Near the settlement of Karavshin, the river is called the same name.  Crossing the national border, the river merges with the Kshemysh River (Kshemyshsai) and, further on, the river receives the name of Isfara.

 Actions:

Establishment of stakeholder groups, i.e. Small Basin Councils (SBC) representing local authorities, NGOs, water users and local communities.  SBC secretariats independently hold internal semi-annual meetings.  Thus, the SBCs serve as platforms to exchange opinions and information as well as take joint decisions associated with the enhancement of the overall situation in the river basin.

Results:

Creation of national Small Basin Councils (SBC) on the Isfara River allowed a platform for exchanging opinions and information as well as for drawing joint decisions to improve the overall situation in the Isfara River Basin, including the development of the IWRM basin plan for the target basin.

ISV-1 is universal and easy to use.  Measurements are presented on the display in digital form and in speed units.  Use of the electronic device for measuring water speed and, based on it, water consumption facilitates the work of hydro-accountants.

Device characteristics:

• no rubbing details in the design;
• no requirement for preliminary and subsequent periodic calibration;
• measurement results do not depend on changes in physical composition and properties of water;
• simplifies the process of water speed measuring and, therefore, water consumption accounting;
• available in stationary and portable designs;
• measurement error is comparable to this of the widely used GR-21;
• small overall dimensions and weight;
• relatively low cost, etc.

 The device is universal and its measurement results do not depend on water composition and properties, except for temperature (desired range 0 to +30°C). The device underwent successful testing and was deployed in 5 Basin Irrigation System Administrations (BISA): Chirchik-Akhangaran BISA, Zarafshan BISA, Syr Darya-Sokh BISA, Amu-Surkhan BISA, Lower Amu Darya BISA.

Actions:

• manufacturing of 5 ISV-1 devices;
• training of BISA hydro-accountants on device operation and use.

Results:

• 5 above-stated BISAs accepted (acceptance certificate) and are presently using them;
• the device’s testing is continuing for different irrigation system conditions;
• the device developers continue receiving positive feedback from leading hydro-accountants;
• at present, the works to enhance and certify the device are in progress.

Lessons learnt:

Introduction of IWRM principles is the pre-requisite of stable and fair water supply irrespective of a given water user’s location.

Recommendations:

Currently, when local stakeholders are represented in SBCs and are engaged in joint water management, it is necessary to hold thematic seminars to ensure sustainability of SBC operations in the future.  In the long term, it might be possible to establish a joint body to manage the whole river basin.

Lessons learnt:

Application of the device increases the efficiency of data collection compared to the currently used equipment, as well as promotes rational and effective use of water resources due to higher accuracy, reliability and efficiency of irrigation water accounting data and saving of material and labor resources.

Recommendations:

The device is recommended for use on large canals and collector facilities as well as intra-farm water supply networks.  Today, the majority of WUAs do not have revolver meters or other water-measuring devices in their disposal, so fitting them with such units would improve WUAs overall technical capacities.

With the ongoing acute deficit of hydro-accountants, any technical college graduate would be able to use ISV-1.

Development and implementation of basin plans constitute principal elements of integrated water resources management.  Multi-agency coordination mechanism via basin councils or coordination groups is an important advantage of IWRM.  This approach allows streamlined coordination and synergy of actions on all levels of management hierarchy.
