Description

Major hydrologic effects of land-use change such as afforestation, deforestation and agricultural intensification have known impacts on surface runoff as well as climate. Although typically we think of the hydrologic impact of land-use change primarily in terms of the increased peak discharges that are responsible for flooding, there are a range of other impacts. One of the most important additional impacts is an increase in surface runoff volume which may contribute to downstream flooding. Other important impact is seasonal changes in runoff volume and time. The objective of this study is to address the broad question as to how watershed management and land-use impact water production from watersheds in Utah. The scale of interest is regional watersheds specified by USGS 8 digit Hydrologic Unit Code (HUC) subbasins. The hypothesis of this study will be to quantify the water balance terms for specific hydrologic subbasins of interest in 8 digit HUC’s within Utah based on historic data, to examine trends in the historic data and to relate these water balance quantities to land-use and watershed management in the study subbasins. The results of this study will enhance the understanding and capability for estimating the water availability in Utah and assist in managing the water resources and how it is linked to land-use changes.
