A general framework for understanding the response of the water cycle to global warming over land and ocean Hydrology and Earth System Sciences DOI 10.5194/hess-18-1575-2014 6 May 2014 In an attempt to develop a simple framework for local-scale analysis we found that the climate model output shows a remarkably close relation to the long-standing Budyko framework of catchment hydrology.

Ensemble projections of future streamflow droughts in Europe Hydrology and Earth System Sciences DOI 10.5194/hess-18-85-2014 9 January 2014 This paper addresses the issue of future developments in streamflow drought characteristics across Europe. Read more
Quantifying mesoscale soil moisture with the cosmic-ray rover Hydrology and Earth System Sciences DOI 10.5194/hess-17-5097-2013 17 December 2013 This paper explores the challenges and opportunities for mapping soil moisture over large areas using the cosmic-ray rover. Read more
Statistical analysis to characterize transport of nutrients in groundwater near an abandoned feedlot Hydrology and Earth System Sciences DOI 10.5194/hess-17-4897-2013 6 December 2013 Surface water from a lagoon and groundwater samples from 17 wells within and near an abandoned feedlot in northwestern Minnesota, USA, were analyzed for carbon, nutrients, and field parameters.

Rainfall estimation using moving cars as rain gauges – laboratory experiments Hydrology and Earth System Sciences DOI 10.5194/hess-17-4701-2013 28 November 2013 The spatial assessment of short time-step precipitation is a challenging task. Low density of observation networks, as well as the bias in radar rainfall estimation motivated the new idea of exploiting cars as moving rain gauges with windshield wipers or optical sensors as measurement devices.

Inverse streamflow routing Hydrology and Earth System Sciences DOI 10.5194/hess-17-4577-2013 19 November 2013 Here we develop a methodology to invert the routing process, i.e., to derive the spatially distributed runoff from streamflow (e.g., measured at gauge stations) by inverting an arbitrary linear routing model using fixed interval smoothing.

A thermodynamic approach to link self-organization, preferential flow and rainfall–runoff behaviour Hydrology and Earth System Sciences DOI 10.5194/hess-17-4297-2013 1 November 2013 This study investigates whether a thermodynamically optimal hillslope structure can, if existent, serve as a first guess for uncalibrated predictions of rainfall–runoff.

Comparative assessment of predictions in ungauged basins – Part 2: Flood and low flow studies Hydrology and Earth System Sciences DOI 10.5194/hess-17-2637-2013 9 July 2013 The objective of this paper is to assess the performance of methods that predict low flows and flood runoff in ungauged catchments. The aim is to learn from the similarities and differences between catchments in different places, and to interpret the differences in performance in terms of the underlying climate-landscape controls.

Palaeoclimatological perspective on river basin hydrometeorology: case of the Mekong Basin Hydrology and Earth System Sciences DOI 10.5194/hess-17-2069-2013 31 May 2013 Our main aim in this paper is to develop a river basin scale approach for assessing interannual hydrometeorological and discharge variability on long, palaeological, time scales. For the development of the basin-wide approach, we used the Mekong River basin as a case study area, although the approach is also intended to be applicable to other basins. Read more
Reducing cloud obscuration of MODIS snow cover area products by combining spatio-temporal techniques with a probability of snow approach Hydrology and Earth System Sciences DOI 10.5194/hess-17-1809-2013 13 May 2013 This study develops a rule-based, multistep method for removing clouds from MODIS snow cover area images. The methods used include combining images from more than one satellite, time interpolation, spatial interpolation, and estimation of the probability of snow occurrence based on topographic information.
