Hydropedology: synergistic integration of pedology and hydrology. Water Resources Research. 42(5):W05301. Interpretive Summary: This paper presents a vision that advocates hydropedology as an advantageous integration of pedology and hydrology for studying the intimate relationships between soil, landscape, and hydrology. Landscape water flux is suggested as a unifying precept for hydropedology, through which pedologic and hydrologic expertise can be better integrated. Landscape water flux here encompasses the storage, pathways, residence times, and spatio-temporal organization of water in the root and deep vadose zones within the landscape. After illustrating multiple knowledge gaps that can be addressed by the synergistic integration of pedology and hydrology, we suggest five scientific hypotheses that are critical to advancing hydropedology and enhancing the prediction of landscape water flux. We then present three interlinked strategies for achieving the stated vision. It is our hope that, by working together, hydrologists and pedologists, along with scientists in related disciplines can better guide data acquisition, knowledge integration, and model-based prediction so as to advance the hydrological sciences in the next decade and beyond.
