      abstract     = {The Tibetan Plateau is the source of most of Asia's major
                      rivers and has been called the Asian Water Tower. Detailed
                      knowledge of its hydrogeology is paramount to enable the
                      understanding of groundwater dynamics, which plays a vital
                      role in headwater areas like the Tibetan Plateau.
                      Nevertheless, due to its remoteness and the harsh
                      environment, there is a lack of field survey data to
                      investigate its hydrogeology. In this study, borehole core
                      lithology analysis, soil thickness measurement, an altitude
                      survey, hydrogeological surveys, and hydrogeophysical
                      surveys (e.g. magnetic resonance sounding – MRS,
                      electrical resistivity tomography – ERT, and transient
                      electromagnetic – TEM) were conducted in the Maqu
                      catchment within the Yellow River source region (YRSR). The
                      hydrogeological surveys reveal that groundwater flows from
                      the west to the east, recharging the Yellow River. The
                      hydraulic conductivity ranges from 0.2 to 12.4 m d−1.
                      The MRS sounding results, i.e. water content and hydraulic
                      conductivity, confirmed the presence of an unconfined
                      aquifer in the flat eastern area. Based on TEM results, the
                      depth of the Yellow River deposits was derived at several
                      places in the flat eastern area, ranging from 50 to 208 m.
                      The soil thickness measurements were done in the western
                      mountainous area of the catchment, where hydrogeophysical
                      and hydrogeological surveys were difficult to be carried
                      out. The results indicate that most soil thicknesses, except
                      on the valley floor, are within 1.2 m in the western
                      mountainous area of the catchment, and the soil thickness
                      decreases as the slope increases. These survey data and
                      results can contribute to integrated hydrological modelling
                      and water cycle analysis to improve a full-picture
                      understanding of the water cycle at the Maqu catchment in
                      the YRSR. The raw dataset is freely available at

                      and the dataset containing the processed ERT, MRS, and TEM
