Improving Irrigation Water Management
National Water Resources Management (NWRM) project, 2014, SDC funded, Tajikistan
Pilot irrigation technology projects were designed to demonstrate improved irrigation management to water users, water user associations (WUAs), and district-level irrigation system officials. The technologies proposed for demonstration are: drip irrigation for production of fruit and vegetable crops; short-furrow irrigation; laser leveling for surface irrigation and proper sizing of irrigation systems; installation of flow measurement structures within pilot WUAs to introduce volumetric water delivery to farmers; construction of flow measurement structures at the head of secondary canals for volumetric water delivery to WUAs; SMS-based flow monitoring system within WUAs; SMS-based flow monitoring system for measuring flows to WUAs. In addition, a series of training modules for water users, WUAs and irrigation officials were designed for improving their capacity to manage water better.
Water Users Associations Development Support Project, 2013-2014, World Bank funded, Azerbaijan
Excel-based WUA water use plans and water distribution plans were developed, and more than 40 WUAs were trained in implementing these improved procedures. The same WUAs were trained in improved on-farm water management practices also.
SMS-based Flow Monitoring System, 2014, funded by USAID, Tajikistan
Designed an innovative SMS-based flow monitoring system for the Lower Kafarnihon River Basin consisting of more than 20 WUAs. This included design (and construction in the near future) of several flow measurement structures on irrigation and drainage channels in order to calculate the volume of water delivered to each WUA within the river basin. This proposal would be submitted for funding from World Bank or ADB in the near future.
Integrated Water Resources Management – Fergana Valley Project, 2010-2013, SDC funded, Kyrgyzstan, Tajikistan and Uzbekistan
WUAs were established based upon hydrographic principle, and flow measurement structures were installed at the head of all the secondary canals that supply water to WUAs and the main canal operations were partially automated/computerized, in order to monitor flows delivered to WUAs and improve equity in water distribution to WUAs, estimate water conveyance losses in the main canals, and minimize system operational losses. In addition, within the territories of some selected WUAs, flow measurement structures and gates were installed at key locations for improved water control.
Water Productivity Improvement at Plot Level Project, 2010-2013, SDC funded, Fergana Valley (Kyrgyzstan, Tajikistan and Uzbekistan)

This facilitated a two-way communication between the researchers and farmers. We worked with 15 ((5 in each country) different government organizations and NGOs). Region specific information on improved irrigated agricultural practices was disseminated through TV talk shows, brochures, booklets, and pamphlets, and through Farmer Field Schools.
Egypt Water Use and Management Project (EWUP), USAID, Egypt (1977 – 1984)
Through the Egypt Water Use and Management Project, an interdisciplinary team management at Colorado State University was initiated. Similarly, by introducing interdisciplinary teams to Egypt, efforts of the Ministries of Irrigation and Agriculture were combined. The interdisciplinary team assessed the irrigation capacities of various components of the system. This changed management of the canal systems, changed management and water supply of farm channels, assisted in initiating land leveling, and farmer organizations. Impacted cotton yields by 40%, rice yields by 25%, and started a farm-water management program. Presently Egypt is carrying out a national irrigation improvement program of several hundred million dollars that grew out of the EWUP Project.
Water Management Synthesis I & II Projects, 1978 – 1988, USAID funded, Global
Through WMS developed Diagnostic Analysis of Irrigation Systems approach (DA), workshops on DA of Irrigation Systems were conducted in several different countries in Asia and Africa, to train water management professionals in this approach and methodology to improve performance of irrigated agriculture in developing countries. This is a multi-disciplinary, field-oriented approach for identifying the root causes of problems faced by irrigation schemes in developing countries, and search for solutions, and implement the solutions and monitor the performance again. This is a cyclical process. The same approach evolved into a much comprehensive approach called Management Improvement Process for Irrigated Agriculture, and has been successfully applied for improving performance of irrigation systems in Arizona.
On-Farm Water Management Research Project, 1972 – 1976, USAID funded, Pakistan
Conducted initial studies and identified program of on-farm water management in Pakistan contradicting the published reports and policies of Pakistan, numerous donor agencies, and international consulting firms.

Conducted a detailed irrigation infrastructure needs assessment of two sprinkler irrigation schemes in Romania: Tecuci-Nicoresti (11,000 ha), and Sadova-Corabia (40,000 ha). The assessed infrastructure for each irrigation scheme consisted of a pumping station on a river, pipeline (with surge tank) to transport water to a higher elevation and empty the water into a storage reservoir, canal system to convey water to different WUAs, and an underground pipe network to distribute water within each WUA, and hydrants and above ground lateral pipes with sprinklers for application of irrigation to crops.
