1 Khon Kaen University. Faculty of Engineering. Office of Water Resource Development, KKU-NZ-UBON Program. 1986. Report of a survey to ascertain the utilization of weirs on Ubon Province. Khon Kaen, Thailand: Khon Kaen University. 43p.
(Location: IWMI-HQ Call no: P 183 Record No: H0887)
This report is the result of a survey to ascertain the utilization of weirs in Ubon Province. The sites selected were in Amphur (District) Amnatcharoen, Amphur Warinchumrab and Amphur Dej-Udom. In each Amphur the weirs were randomly chosen for a total of 15 sites in order to obtain some basic data for implementing weir construction. The survey was divided into (1) study of the weir (2) interviews with villagers concerning building of the weir, utilization, maintenance and villagers' views on the weir. It was observed that most of the weirs built in those three Amphurs could store water over the dry season. Villagers use water mainly to grow vegetables, feed livestock and for fishing. During the wet season, if the rainfall is erratic, villagers pump water from the weir into rice fields. The main problems were that the crests of weirs were too low, only a small amount of water could be stored for the dry season and sedimentation occurred around the front of the weir. Most villagers prefer to have weirs with an adjustable crest. This type of weir is similar to weirs constructed for the KKU-N.Z. project.

The use of shallow wells, equipped with small pumps, to lift groundwater has spread rapidly in many agricultural regions of tropical monsoonal Asia. In Sri Lanka, the rapid and pervasive invasion of agro-wells and pumps drew the attention of policymakers and researchers, but many questions were left unanswered due to lack of research in the area. This study aims to fill this gap in knowledge, based on observations and data obtained in field surveys conducted in major and minor irrigation schemes in the dry zone of Sri Lanka. This report gives the key findings of this study into the pattern, extent and causes of the spread and use of agro-wells and pumps in traditional villages and irrigated settlement schemes. It investigates farmer investments in agro-wells and pumps, the private internal rate of return to these investments, the economic viability of investments and incentives for farmers to make investments
