Impact of landuse on runoff in mountain catchments of different scales
hydrological regime landuse change
2015/2/4
The paper presents two approaches to the analysis of the impacts of landuse changes on hydrological regime in mountain catchments of northern Slovakia. An intersite comparison of measured data along t...
Arctic Snow Cover Information for Hydrological Investigations at Various Scales
Arctic Snow Cover Information Hydrological Investigations Various Scales
2009/10/23
Routine snow survey and snow gauge data provided by weather stations establish
snow-on-the-ground and snowfall time series but they lack a spatial dimension.
Of particular importance to arctic hydro...
Model Sophistication in Relation to Scales in Snowmelt Runoff Modeling
Model Sophistication Scales Snowmelt Runoff Modeling
2009/10/23
Snowmelt induced runoff from river basins is usually successfully simulated using
a simple degree-day approach and conceptual rainfall-runoff models. Fluctuations
within the day can not be described...
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...
Translating environmental xenobiotic fate models across scales
xenobiotics deterministic models
2009/6/8
The classical models developed for degradation and transport of xenobiotics have been derived with the assumption of homogeneous environments. Unfortunately, deterministic models function well in the ...
Hydrological response to different time scales of climatological drought：an evaluation of the Standardized Precipitation Index in a mountainous Mediterranean basin
Standardized Precipitation Index drought conditions
2009/5/18
At present, the Standardized Precipitation Index (SPI) is the most widely used drought index to provide good estimations about the intensity, magnitude and spatial extent of droughts. The main advanta...
In this paper, the second of a series, we apply the models discussed in Part 1 to a significant case study. The nature of the catchment under study, the transport phenomena investigated (i.e. nitrates...
The paper describes the theoretical framework for a class of general continuous models of the hydrologic response including both flow and transport of reactive solutes. The approach orders theoretical...
Analysis of the runoff response of an alpine catchment at different scales
runoff response alpine different scales
2009/5/12
To understand how hydrological processes are related across different spatial scales, 201 rainfall runoff events were examined in three nested catchments of the upper river Saalach in the Austrian Alp...
Evaluating the risk of non-point source pollution from biosolids：integrated modelling of nutrient losses at field and catchment scales
non-point source pollution biosolids nutrient losses catchment scales
2009/5/6
A semi-distributed model, INCA, has been developed to determine the fate and distribution of nutrients in terrestrial and aquatic systems. The model simulates nitrogen and phosphorus processes in soil...
The sensitivity of catchment runoff models to rainfall data at different spatial scales
rainfall runoff sensitivity
2009/3/25
The sensitivity of catchment runoff models to rainfall is investigated at a variety of spatial scales using data from a dense raingauge network and weather radar. These data form part of the HYREX (HY...
Accuracy of rainfall measurement for scales of hydrological interest
rainfall accuracy raingauge radar
2009/3/24
The dense network of 49 raingauges over the 135 km2 Brue catchment in Somerset, England is used to examine the accuracy of rainfall estimates obtained from raingauges and from weather radar. Methods f...
Rainfall dynamics at different temporal scales: A chaotic perspective
rainfall chaos scaling correlation dimension
2009/3/24
This study of the behaviour of rainfall dynamics at different temporal scales identifies the type of approach most suitable for transformation of rainfall data from one scale to another. Rainfall data...
