Abstract

Land use and land cover change (LULCC), a process of human modification of Earth’s terrestrial surface, affects biodiversity, climate change, watershed hydrology, and other processes on the Earth largely in the forms of urbanization, agriculture, and deforestation. Urban and suburban development, primarily increasing impervious surface area, can dramatically influence watershed hydrology by reducing infiltration and increasing runoff and, hence, raising the possibility of increased storm flow and flood frequency. Hydrologic models provide the capability to comprehend the complex hydrologic processes and have been widely and effectively used to understand the hydrologic impact of LULCC. Despite much progress made in the study of the hydrologic impact of LULCC, there are still numerous uncertainties and even controversies. Interdisciplinary and multidisciplinary collaborations can contribute to a comprehensive and improved understanding of the hydrologic impact of LULCC and, therefore, help decision makers in watershed management practices.
