Streamflow Response to Converting Arizona Chaparral in a Mosaic Pattern

From the Proceedings of the 1986 Meetings of the Arizona Section - American Water Resources Association, Hydrology Section - Arizona-Nevada Academy of Science and the Arizona Hydrological Society - April 19, 1986, Glendale Community College, Glendale, ArizonaConverting 55% of an Arizona chaparral watershed to grass in a mosaic pattern, giving major consideration to wildlife habitat values, water quality, and landscape esthetics, produced an average of 68 mm of extra streamflow per year from the watershed during a 4-year evaluation period. When the increased streamflow was prorated to the area actually treated, the increase amounted to 124 mm. Increases in streamflow were largest in winter, and streamflow was extended considerably longer into the dry periods than before treatment.This article is part of the Hydrology and Water Resources in Arizona and the Southwest collections.
