Special Issue Information

Dear Colleagues,

Water covers about 72% of the Earth’s surface, mostly with oceans and sea, and minor portions of water exist on Earth as groundwater, water vapour, and clouds. Geohydrological process can be defined hydrological characteristics of aquifers or rocks and their impacts on groundwater flow, groundwater quantity and groundwater quality. In an arid region, average annual precipitation was estimated to be less than 500 mm and average annual evapotranspiration greater than 800 mm as well as spatiotemporal variability in groundwater quantity and quality. This region covers more than a quarter of Earth's land surface.    

Recently, geospatial technology, hydrological models,  and machine learning models permitted better understanding and modelling geohydrological process. They have proven to be excellent tools for investigating the impacts of land use/ cover changes on climate change and the consequent impacts of these changes on groundwater quality and quality over a regional scale with low cost and time-consuming.

The main objective of this special issue is to gather the recent works that employed geohydrological process in an arid region. The potential research topics include the following: 

  • Water resources management
  • Geohydrology and remote sensing
  • Soil water science
  • Groundwater hydrology and information science
  • Hydrochemistry and groundwater pollution
  • Policy analysis and managements
  • Socio-hydrology
  • Aquifer characteristics
  • Groundwater risk assessment
  • Regional groundwater flow
  • Impact of LULC on groundwater quality and quantity

Hydrological signatures, i.e., statistical features of streamflow time series, are used to characterize the hydrology of a region. A relevant problem is the prediction of hydrological signatures in ungauged regions using the attributes obtained from remote sensing measurements at ungauged and gauged regions together with estimated hydrological signatures from gauged regions. The relevant framework is formulated as a regression problem, where the attributes are the predictor variables and the hydrological signatures are the dependent variables. Here we aim to provide probabilistic predictions of hydrological signatures using statistical boosting in a regression setting. We predict 12 hydrological signatures using 28 attributes in 667 basins in the contiguous US. We provide formal assessment of probabilistic predictions using quantile scores. We also exploit the statistical boosting properties with respect to the interpretability of derived models. It is shown that probabilistic predictions at quantile levels 2.5% and 97.5% using linear models as base learners exhibit better performance compared to more flexible boosting models that use both linear models and stumps (i.e., one-level decision trees). On the contrary, boosting models that use both linear models and stumps perform better than boosting with linear models when used for point predictions. Moreover, it is shown that climatic indices and topographic characteristics are the most important attributes for predicting hydrological signatures. Full article
