Estimation of Monthly River Discharge from Danish Catchments
Estimation Monthly River Discharge Danish Catchments
<
2009/10/22
To simulate the nutrient loading of Danish coastal waters, river discharge from
unmonitored areas must be assessed. In an attempt to identify the most suitable
method, for this purpose eight differe...
SCS CURVE NUMBER ESTIMATION USING REMOTE SENSING NDVI IN A GIS ENVIRONMENT
Soil Conservation Service Curve Number Normalized Difference Vegetation Index GIS ENVIRONMENT
<
2009/10/12
The Soil Conservation Service Curve Number (SCS-CN) method is a simple, widely used and efficient procedure for determining the expected amount of runoff from rainfall in a particular area. Its use, h...
A MODEL FOR SITE SPECIFIC ESTIMATION OF THE AVAILABLE SOIL WATER CONTENT AND THE EVAPOTRANSPIRATION IN FOREST ECOSYSTEMS
water balance model EVAPOTRANSPIRATION FOREST ECOSYSTEMS
<
2009/10/12
A vertical water balance model is presented which calculates a set of different water balance parameters (evapotranspiration, interception, runoff and soil water content) for various land covers and i...
DEM-RS-GIS BASED STORM RUNOFF HYDROGRAPH ESTIMATION FOR THE HEART RIVER SUB-BASIN, MISSOURI RIVER BASIN
Remote sensing Normalized Difference Vegetation Index geographic information system
<
2009/10/12
Accurate representation of the physical and biological features of the landscape within the watershed is required as the extent and type of watershed cover affects the movement of water in the hydrolo...
ESTIMATION OF HYDRAULIC PARAMETERS FROM SURFACE GEOPHYSICAL METHODS, KALIAPANI ULTRAMAFIC
HYDRAULIC PARAMETERS groundwater resources SURFACE GEOPHYSICAL METHODS
<
2009/10/12
A knowledge of aquifer parameters is essential for the assessment and management of groundwater resources. Conventionally, these parameters are estimated through pumping tests carried out on bore well...
Regional estimation of daily to annual regional evapotranspiration with MODIS data in the Yellow River Delta wetland
Evapotranspiration Yellow River Delta daily annual
<
2009/10/10
Evapotranspiration (ET) from the wetland of the Yellow River Delta (YRD) is one of the important components in the water cycle, which represents the water consumption by the plants and evaporation fro...
Estimation of actual evapotranspiration of Mediterranean perennial crops by means of remote-sensing based surface energy balance models
evapotranspiration surface energy balance Mediterranean perennial crops
<
2009/7/22
Actual evapotranspiration from typical Mediterranean crops has been assessed in a Sicilian study area by using surface energy balance (SEB) and soil-water balance models. Both modelling approaches us...
Estimation of permafrost thawing rates in a sub-arctic catchment using recession flow analysis
permafrost thawing rates recession flow analysis sub-arctic catchment
<
2009/7/22
Permafrost thawing is likely to change the flow pathways taken by water as it moves through arctic and sub-arctic landscapes. The location and distribution of these pathways directly influence the car...
Improved estimation of flood parameters by combining space based SAR data with very high resolution digital elevation data
synthetic aperture radar devastating catastrophes flood parameters
<
2009/7/22
Severe flood events turned out to be the most devastating catastrophes for Europe's population, economy and environment during the past decades. The total loss caused by the August 2002 flood is estim...

An analytical solution for the estimation of the critical available soil water fraction for a single layer water balance model under growing crops
soil water single layer water balance model growing crops
<
2009/6/5
In the framework of simplified water balance models devoted to irrigation scheduling or crop modelling, the relative transpiration rate (the ratio of actual to maximal transpiration) is assumed to dec...
Rating curve estimation using local stages, upstream discharge data and a simplified hydraulic model
Rating curve estimation local stages upstream discharge data
<
2009/5/27
This article proposes a methodology for synthesising the rating curve in one or more cross-sections of a watercourse provided with stage data, when a reliable rating curve and stage data are also avai...
Methods for estimation loads transported by rivers
rivers loads transported North-East Scotland
<
2009/5/26
Ten methods for estimating the loads of constituents in a river were tested using data from the River Don in North-East Scotland. By treating loads derived from flow and concentration data collected e...
A new approach for estimation suspended sediment yield
sediment yield sediment routine sediment concentration
<
2009/5/26
A semi-distributed conceptual model, HBV-SED, for estimation of total suspended sediment concentration and yield at the outlet of a catchment was developed and tested through a case study. The base of...
