Less rain,more water in ponds:a remote sensing study of the dynamics of surface waters from 1950 to present in pastoral Sahel (Gourma region,Mali)
rain remote sensing study dynamics of surface waters pastoral Sahel
2010/2/20
Changes in the flooded area of ponds in the Gourma region from 1950 to present are studied by remote sensing, in the general context of the current multi-decennial Sahel drought. The seasonal and inte...

Comparative rainfall data analysis from two vertically pointing radars,an optical disdrometer,and a rain gauge
rainfall data analysis vertically pointing radars optical disdrometer rain gauge
2009/11/2
The authors present results of a comparative analysis of rainfall data from several ground-based instruments. The instruments include two vertically pointing Doppler radars, S-band and X-band, an opti...
COMPARISON OF MEAN RAIN CATCH OF VARIOUS GAUGE NETWORKS
COMPARISON MEAN RAIN CATCH VARIOUS GAUGE NETWORKS
2009/10/29
After the substitution of stereo for horizontal orifices of rain gauges on
open steep slopes, the mean network catch in a subbasin with prevailing
windward exposure was increased by 11 O/o. In a sub...
The relation between rain movement and areal reduction of rain intensity is
investigated. An approach for calculating areal reduction factors from point
hyetographs and storm speed is suggested. Ver...
Rain-Runoff Parameters for Six Small Gauged Urban Catchments
Rain-Runoff Parameters Six Small Gauged Urban Catchments
2009/10/26
The interpretation of rain-runoff measurements from 6 small (less than 17 ha)
urban catchments is described. The recording period covers mostly 1979-1983.
Relations between rain- and runoff depths w...
The orographic and temporal gradients of rainfall in a mountainous watershed
in southwestcrfi British Columbia have been analyzed and streamflow has been
estimated using a watershed model. The study...
Correction of Daily Rain Gauge Measurements in the Baltic Sea Drainage Basin
Daily Rain Gauge Measurements Baltic Sea Drainage Basin
2009/10/23
Within the framework of BALTEX regular measurements made at about 4,200
rain gauge sites have been collected by the BALTEX Meteorological Data Centre.
This network of rain gauges is about 10 times d...
Acid deposition, land-use change and global change：MAGIC 7 model applied to Aber, UK (NITREX project) and Risdalsheia, Norway (RAIN and CLIMEX projects)
Acid deposition MAGIC (version 7) global change
2009/6/5
Nitrogen processes are now included in a new version of MAGIC (version 7), a process-oriented catchment-scale model for simulating runoff chemistry. Net retention of nitrogen (N) is assumed to be cont...
Evaluation of a conceptual rainfall forecasting model from observed and simulated rain events
rainfall forecasting simulated rain events
2009/6/5
Very short-term rainfall forecasting models designed for runoff analysis of catchments, particularly those subject to flash-floods, typically include one or more variables deduced from weather radars...
Evaluation of a scaling cascade model for temporal rain- fall disaggregation
scaling cascade model fall disaggregation temporal rain
2009/5/27
The possibility of modelling the temporal structure of rainfall in southern Sweden by a simple cascade model is tested. The cascade model is based on exact conservation of rainfall volume and has a br...
Limited-area short-range ensemble predictions targeted for heavy rain in Europe
Deutsche Wetterdienst quantitative precipitation forecasts ensemble prediction system
2009/5/18
Inherent uncertainties in short-range quantitative precipitation forecasts (QPF) from the high-resolution, limited-area numerical weather prediction model DMI-HIRLAM (LAM) are addressed using two diff...
Chemical characterization of fog and rain water collected at the eastern Andes cordillera
fog eastern Andes cordillera rain water
2009/5/18
During a three month period in 2003 and 2004, the chemistry of fog and rainwater were studied at the "El Tiro" site in a tropical mountain forest ecosystem in Ecuador, South America. The fogwater samp...
Distance in spatial interpolation of daily rain gauge data
spatial interpolation daily rain gauge data
2009/5/13
Spatial interpolation of rain gauge data is important in forcing of hydrological simulations or evaluation of weather predictions, for example. This paper investigates the application of statistical ...
