Development of Geoinformatic Database for Water Resources Management in Tambon Sarapee, Sarapee District, Chiang Mai Province

Abstract

The objectives of the development of geoinformatic database for water resources management in Tambon Sarapee, Sarapee District, Chiang Mai Province were to collect information on water resources infrastructure and water resources management program, to study both the current and future approach on water resources management and to apply geoinformatics to water resources management through the participation of the local community and network organizations. Spatial analysis with descriptive statistics and trend analysis using least square method were implemented. The findings revealed that the terrain of the north is higher than that in the south. There is a river flowing through the area from the north to the south. High density settlements are noted along both sides of Highway 108. The water supplies include rainfall of over 1,000 millimeters per year and runoff of 1,804.48 million cubic meters. The water sources consist of shallow wells, artesian wells, shallow ponds and canals, with the total water volume of 1,782,797.77 cubic meters per year. The water demand for consumption is 375,278.40 cubic meters per year, while the water demand for agriculture is 2,791,370.27 cubic meters per year. This information can be used as guidelines for water management and allocation in terms of consumption, environmental preservation, drought protection, flood protection and consciousness promotion.
