Проблема, которая решается применением практики | Acute water shortage; land degradation in the village of Sadu Shakirov; abandoned irrigated arable lands used only for year-round cattle grazing. For a long time, the irrigation canal was not operation-al and, thus, became dilapidated. The situation in the area was aggravated by climate change impacts (de-creased quantity of early spring, summer and winter precipitation, increased average annual temperature, spring and autumn frost bites and summer droughts). |
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:

Примененные в практике инструменты | Method of autumn and winter water-charging irrigation |
Electronic Water Current Meter (ISV-1) |
Описание практики и ее результаты | Actions: Results: Financial and economic: Technical: |
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:
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.

Какие уроки и рекомендации можно извлечь из практики | Lessons learnt: Application of water-charging irrigation demonstrated the efficiency of water use and allowed local popula-tion to go through winter without losing livestock. Recommendations: |
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. |

Краткая информация о проекте | Project title: Fall and early spring Irrigation of arable land and pastures as an adaptation mechanism of ra-tional water use in Southern Kazakhstan Duration: May 1, 2008 – April 30, 2009 Project goal and objectives: reduce land degradation due to climate change by way of rational use of irriga-tion water. The project was implemented to prevent loss of cattle due to forage shortage during alternating droughty years. Project beneficiaries: local population. Project implementer: Kogal LLC |
Project title: Commercial contract engagement with 5 BISAs. Project duration: 2015-2017. Project goal and objectives: create an easy-to-operate tool to measure water speed (current) within the 0.2-5.0 m/s range for deployment on facilities of the Ministry of Agriculture and Water Management (MAWM) of the RUz. Project beneficiaries: BISAs of the MAWM of the RUz. Project implementer: Head Water Administration (HWA) of the MAWM of the RUz. |
