VERSATILE MOBILE AND STATIONARY LOW-COST APPROACHES FOR HYDROLOGICAL MEASUREMENTS
flood monitoring geo-crowd sourcing image-to-geometry intersection time lapse image analysis smartphone application low-cost camera system Raspberry Pi
2018/6/4
In the last decades, an increase in the number of extreme precipitation events has been observed, which leads to increasing risks for flash floods and landslides. Thereby, conventional gauging station...

land use land cover vegetation vigour runoff soil erosion remote sensing Geographic Information System GIS
2015/8/11
The paper discusses the applications of satellite remote sensing and GIS on characterization and spatial modeling of runoff and soil erosion of Birantiya Kalan, an arid watershed in the district of Pa...
Frozen soil parameterization in a distributed biosphere hydrological model
Frozen soil parameterization distributed biosphere hydrological model
2010/4/7
In this study, a frozen soil parameterization has been modified and incorporated into a distributed biosphere hydrological model (WEB-DHM). The WEB-DHM with the frozen scheme was then rigorously evalu...
Global spatial optimization with hydrological systems simulation:application to land-use allocation and peak runoff minimization
Global spatial optimization hydrological systems simulation land-use allocation peak runoff minimization
2010/2/20
A general methodology is presented to integrate complex simulation models of hydrological systems into optimization models, as an alternative to scenario-based approaches. A gradient-based hill climbi...
Calibration analysis for water storage variability of the global hydrological model WGHM
Calibration analysis water storage variability global hydrological model WGHM
2010/2/1
The aim of this study is to provide an improved global simulation of continental water storage variations by calibrating the WaterGAP Global Hydrology Model (WGHM) for 28 of the largest river basins w...
Efficient implementation of inverse approach for forecasting hydrological time series using micro GA
Efficient implementation inverse approach hydrological time series micro GA
2009/12/4
This paper implements the inverse approach for forecasting hydrological time series in an efficient way using a micro-GA (mGA) search engine. The inverse approach is based on chaos theory and it invol...
RAINFALL INTERCEPTION IN A FOREST IN THE VELEN HYDROLOGICAL REPRESENTATIVE BASIN
RAINFALL INTERCEPTION VELEN HYDROLOGICAL REPRESENTATIVE BASIN
2009/10/29
In the summer and autumn ot 1973, 25 rain troughs were operating below
canopy and four in clearings of a predominantly coniferous forest in the
Velen hydrological research area. The collected rain w...
A relation between return periods of hydrological events in annual maxima and
partial duration series respectively is shown to be exactly fulfilled when the events
take place according to a Poisson ...
Limitations in Hydrological Interpretations of the Snow Coverage
Limitations Hydrological Interpretations Snow Coverage
2009/10/28
Patterns of the disappearing seasonal snow cover are similar year after year.
This could lead to the assumption that a certain areal extent of snow indicates
always a corresponding volume of snow or...

Glacial-Hydrological Investigations Vernagtferner Glacier Discharge Model
2009/10/28
The report gives a review on the glacial-hydrological work carried out since
1974 in the project "Runoff within and from glaciers" of Sonderforschungsbereich
81 of the Technical University Munich wi...
The hydrological studies of the Greenland technical Organization in Greenland
are being followed up at Copenhagen by hydrological data work as well
as hydrological model-simulation.
The hydrologica...
On Soil Retention Curves and Hydrological Forecasting in Ungauged Catchments
Soil Retention Curves Hydrological Forecasting Ungauged Catchments
2009/10/28
In many physically based hydrological models, there is the requirement to
specify the suction-moisture curve of the soil system. This paper shows that
where the suction moisture curve is known, then...
The Combination of Simulated Discharges of Hydrological Models
Combination Simulated Discharges Hydrological Models
2009/10/27
Hydrological models are frequently used to simulate streamflow. A method for
improving performance is to combine the simulated discharges of two or more
models. Three different methods are given in ...
