• Located in the valley part of the Vakhsh River Basin (river catchment area);
• Deep (below 3 meters) ground water occurrence;
• Middle loamy soils.

The hydro-posts are located in foothill and/or flat areas with the water stream speeds in canals fluctuating between 0.1 and 1.5 m/s

Uneven distribution of irrigation water, lack of water accounting means to ensure observance of recommended irrigation norms for cotton

• Inefficient management of water resources;
• Inefficient planning of water distribution

Tubular water outlet flowmeter

DUV 2/0.005-10 Water Level Sensor

Actions:

- Construction of tubular water outlet flowmeter with removable nozzles (procurement of polyethylene piping to make tubular water outlets and matching nozzles);
- Installation of tubular water outlet flowmeter along temporary sprinklers. 

Results:

Financial and economic:

saving of irrigation water; low cost of irrigation system automation (total kit cost: $500/ha) with the service life of 5 years. 

Technical:

simple design allowing a more even distribution of irrigation water stream among furrows, thus, ensuring the prescribed water supply mode.

Social:

improved working conditions of irrigators; lower labor needs/costs; enhanced mutual trust among farmers and water users.

The DUV 2/0,005-10 Sensor was deployed and demonstrated its efficiency in Jambyl and Southern Kazakhstan Regions.  It allowed to visually and in real-time observe the dynamics of water level fluctuations and completely exclude manual operations and subjectivity in the process of taking readings – a relevant task in the environment of transition to market economy.

Water level sensors were installed in 17 hydro-posts in Southern Kazakhstan Region (Maktaaral District).  In Jambyl Region, the same sensors were installed in 3 hydro-posts in Merke District.

Results:

Technical:

a) immediate data exchange on water volume passing through every water lead to the fields of agricultural producers (farms) as well as automatic transfer of this information to stakeholder organizations (branch of “Kazvodkhoz” Republican State Enterprise (RSE), etc.);

b) archiving the data coming from hydro-posts with its subsequent processing in the form of reports.

Technical and economic:

1) “all in one” – all components of DUV 2/0.005-10 are assembled into one unit/casing, do not require any additional modules and adjustments, i.e. it is an out-of-the-box universal tool to execute monitoring of water reserves irrespective of the availability of power supply and other technical and weather conditions.  The simple Sensor’s design facilitates installation and start-up and commissioning, as well as allows minimizing labor costs;

2) DUV 2/0.005-10 is flexible in terms of installation, data transfer methods, measurement subject (water level or hydro-lock position, etc.);

3) the cost of the measuring unit is 3-4 times less compared to currently available alternatives;

4) DUV 2/0.005-10 designed architecture allows increasing the number of controlled points and performing an integrated monitoring of the whole network.

Lessons learnt:

Installation and deployment of tubular water outlet flowmeter allows to improve the uniformity of irrigation stream’s distribution among furrows and conduct irrigation water accounting.

Recommendations:

It is necessary to widely use the small-scale irrigation automation means like the tubular water outlet flowmeters which have simple design, are convenient to operate, are low-cost and mobile and ensure supply of the prescribed amount of irrigation water.

Lessons learnt:

Deployment of the DUV 2/0.005-10 Water Level Sensor led to increased precision of water level and consumption measurements and higher promptness of information collection compared to any known methods.

Using the device in the conditions of water resources deficiency, on the one hand, will ensure objective accounting of water use and, on the other hand, will promote water conservation among water users which will lead to more efficient technological development of agro-industrial complex and higher labor productivity.

Recommendations:

The success of deploying water level sensors in project hydro-posts facilitated execution of measures to disseminate the positive experience of using the device in the water sector.  Their effect will be even more significant as enhanced quantity and quality indicators will ensure effective management of water resources and water conservation with simultaneous development of irrigated agriculture.
