Description: Institute of Geophysics, University of Lausanne, Lausanne, Switzerland. Self-potentials (SP) are sensitive to water fluxes and concentration gradients in both saturated and unsaturated geological media, but quantitative interpretations of SP field data are often hindered by the superposition of different source contributions and time-varying electrode potentials. Self-potential mapping and close to two months of SP monitoring on a gravel bar were perfor...

By: R. Angulo-jaramillo; V. Trelo-ges; V. Sriboonlue; C. Hammecker; C. Clermont-dauphin; A. C. D. Antonino; S. Siltecho

Description: Department of Plant Science and Land Resource, Faculty of Agriculture, Khon Kaen University, Thailand. Adequate water management is required to improve the efficiency and sustainability of agricultural systems when water is scarce or over-abundant, especially in the case of land-use changes. In order to quantify, to predict and eventually to control water and solute transport into soil, soil hydraulic properties need to be determined precisely. As ...

By: R. Pielke; F. Hossain; A. T. Woldemichael

Description: Department of Civil and Environmental Engineering, Tennessee Technological University (Cookeville), Tennessee, USA. This study adopted a differential land-use/land-cover (LULC) analysis to evaluate dam-triggered land–atmosphere interactions for a number of LULC scenarios. Two specific questions were addressed: (1) can dam-triggered LULC heterogeneities modify surface and energy budget which, in turn, change regional convergence and precipitati...

By: P. J.-f. Yeh; N. Hanasaki; K. Takeuchi; M. Masood

Description: International Centre for Water Hazard and Risk Management (ICHARM), PWRI, Tsukuba, Japan. The intensity, duration, and geographic extent of floods in Bangladesh mostly depend on the combined influences of three river systems, Ganges, Brahmaputra and Meghna (GBM). In addition, climate change is likely to have significant effects on the hydrology and water resources of the GBM basins and might ultimately lead to more serious floods in Bangladesh. However, ...

Description: Department of Civil and Environmental Engineering, The Pennsylvania State University, Sackett Building, University Park, PA 16802, USA. Understanding the implications of potential future climatic conditions for hydrologic services and hazards is a crucial and current science question.

Description: Institute of Hydrology, Wallingford, Oxfordshire, OX10 8BB, UK. A growth factor is the ratio of the T-year extreme value to an index extreme value such as the mean of annual maxima. Whereas a record length of ten or more years may suffice to estimate the index variable, it is generally necessary to blend data from several sites if estimates of exceptional extreme values are to be obtained. Methods of rainfall growth estimation are reviewed, includ...

Description: National Observatory of Athens, Institute for Environmental Research & Sustainable Development, Palea Penteli, Athens, 15236, Greece. The estimation of transient streamflow from stage measurements is indeed important and the study of Dottori, Martina and Todini (2009) (henceforth DMT) is useful, however, DMT seem to miss certain of its practical aspects. The goal is to infer the discharge from measurements of the stage conveniently and with acc...

Description: Institute of Hydrology, Crowmarsh Gifford, Wallingford, Oxon, OX10 8BB, UK. Two contrasting models are used to account for the effects of vegetation on microwave emission from the soil. These are: a simple model which requires two empirically derived parameters as input data (optical depth and single scattering albedo); and a complex discrete model which requires a detailed description of all of the components of the vegetation canopy. Both models accou...

Description: Dipartimento di Ingegneria delle Acque e di Chimica, Politecnico di Bari, Bari, Italia. Understanding the spatial variability of key parameters of flood probability distributions represents a strategy to provide insights on hydrologic similarity and building probabilistic models able to reduce the uncertainty in flood prediction in ungauged basins.

By: L. Marchi; M. Cavalli; S. Trevisani

Description: CNR IRPI, Corso Stati Uniti 4, 35127 Padova, Italy. High-resolution topographic data expand the potential of quantitative analysis of the earth surface, improving the interpretation of geomorphic processes. In particular, the morphologies of the channel beds of mountain streams, which are characterised by strong spatial variability, can be analysed much more effectively with this type of data. In the present study, we analysed the aerial ...

A simple method is proposed to partition a mixture of two populations in suspended particle size data. The method, termed here the differentiation method is based on the function of the lognormal distribution. Suspended material in marine or estuarine situations often consists of difficult-to-interpret complex populations. The treatment of particle size...

Description: Hydrology and Quantitative Water Management Group, Wageningen University, Wageningen, The Netherlands. In many climate impact studies hydrological models are forced with meteorological data without an attempt to assess the quality of these data. The objective of this study is to compare downscaled ERA15 (ECMWF-reanalysis data) precipitation and temperature with observed precipitation and temperature and apply a bias correction to these fo...

Description: Max-Planck-Institute for Meteorology, KlimaCampus, Hamburg, Germany. Validating coarse scale remote sensing soil moisture products requires a comparison of gridded data to point-like ground measurements. The necessary aggregation of in situ measurements to the footprint scale of a satellite sensor (>100 km2) introduces uncertainties in the validation of the satellite soil moisture product. Observed differences between the satellite product and...
