有必要进行一项评估Kyela和Mbarali地区参考蒸散量的气象数据的研究，以便为使用未经计量的改良传统灌溉系统的农民提供信息，以改进水利结构的规划、设计和管理。这些系统由农民通过灌溉组织管理，因此水深是推导和监测流量排放的重要投入。目前的研究使用Penman Monteith方法估算蒸散速率，该方法利用Karonga和Igawa气象站获得的气候数据。粮农组织Climwat - Cropwat 7.0用于分析气候数据，确定作物蒸散量（ETrice）并估计灌溉用水需求。该研究建议Kyela和Mbarali地区的灌溉者利用该研究的结果来评估其灌溉基础设施并调节灌溉流量，如结构中输送的水的深度。关键词：蒸散作用，水力结构，灌溉用水需求
A study to assess meteorological data for reference evapotranspiration in Kyela and Mbarali District was necessary to equip farmers in ungauged improved traditional irrigation systems with information for improved planning, design and management of hydraulic structures. These systems are managed by farmers through irrigator’s organizations thus water depth is an important input in derivation and monitoring flow discharge. The current study estimated Evapotranspiration rate using Penman Monteith method whereby climatic data was obtained from Karonga and Igawa meteorological stations. FAO Climwat – Cropwat 7.0 was used to analyse climatic data, determine Crop Evapotranspiration (ETrice) and estimate irrigation water requirements. The study recommends irrigators in Kyela and Mbarali Districts to utilize results from this study to gauge their irrigation infrastructures and regulate irrigation flows, as depth of water conveyed in the structures Keywords : Evapotranspiration, hydraulic structures, Irrigation water requirements
