Classification of Spatio - Temporal Pattern of Rainfall in Iran Using a Hierarchical and Divisive Cluster Analysis
Cluster Analysis Ward Method Iran
2015/1/6
The identification of spatial rainfall pattern is an essential task for hydrologists, climatologists as well as regional and local planners and managers. This is due to the variability of both the tem...
DERIVING LAND COVER OF A LARGE AGRICULTURAL WATERSHED FROM MULTI-TEMPORAL LANDSAT SCENES
Agricultural NonPoint Source Pollution large watersheds Thematic Mapper hydrologic models
2009/10/13
Determining land-cover characteristics of large watersheds for use in hydrologic models has been enhanced by application of remotely sensed data and the technologies used to interpret them. The object...
Use of soil moisture dynamics and patterns at different spatio-temporal scales for the investigation of subsurface flow processes
soil moisture dynamics subsurface flow processes
2009/7/22
Spatial patterns as well as temporal dynamics of soil moisture have a major influence on runoff generation. The investigation of these dynamics and patterns can thus yield valuable information on hydr...
Spatial and temporal predictions of soil moisture patterns and evaporative losses using TOPMODEL and the GASFLUX model for an Alaskan catchment

2009/5/27
By using topographic indices as derived from a Digital Terrain Models (DTM), it is possible to represent the heterogeneity within a landscape. This heterogeneity can reflect both long term evolutiona...
Using a spatio-temporal dynamic state-space model with the EM algorithm to patch gaps in daily riverflow series
patch gaps daily riverflow series
2009/5/18
A spatio-temporal linear dynamic model has been developed for patching short gaps in daily river runoff series. The model was cast in a state-space form in which the state variable was estimated using...
Throughfall and temporal trends of rainfall redistribution in an open tropical rainforest, south-western Amazonia (Rondônia, Brazil)
rainfall redistribution open tropical rainforest south-western Amazonia
2009/5/13
Throughfall volumes and incident rainfall were measured between 23 August and 2 December 2004 as well as from 6 January to 15 April 2005 for individual rain events of differing intensities and magnitu...
Geostatistical investigation into the temporal evolution of spatial structure in a shallow water table
spatial structure shallow water table
2009/5/13
Shallow water tables near-streams often lead to saturated, overland flow generating areas in catchments in humid climates. While these saturated areas are assumed to be principal biogeochemical hot-sp...
Temporal variability of subsurface stormflow formation
Subsurface stormflow precipitation intensity
2009/4/28
Subsurface stormflow (SSF) can play a key role for the runoff generation at hillslopes. Quantifications of SSF suffer from the limited ability to predict how SSF is formed at a particular hillslope an...
Soil moisture retrieval through a merging of multi-temporal L-band SAR data and hydrologic modelling
Soil moisture synthetic aperture radar moisture content
2009/4/28
The objective of the study is to investigate the potential of retrieving superficial soil moisture content (mv) from multi-temporal L-band synthetic aperture radar (SAR) data and hydrologic modelling....
