Estimating Spatial Curve Number for Hydrologic Response analysis of a small Watershed
Curve Number Satellite Imagery Watershed modeling Geographic Information System GIS
2015/8/11
An approach to estimate the curve number (CN) at each pixel unit of a satellite imagery, which is a key parameter in the widely used Soil Conservation Service Curve Number (SCSCN) hydrologic model, is...
Representativeness of Chemical Analysis of Groundwater
Representativeness Chemical Analysis Groundwater
2009/10/28
This paper raises the question of the representativeness of a single chemical
analysis of groundwater. This is undertaken with the knowledge of the variations
in chemical constituents obtained in th...
EVALUATION OF AN ENZYME LINKED IMMUNOASSAY TECHNIQUE FOR THE ANALYSIS OF ATRAZINE AND DEETHYLATRAZINE (DEA) IN WATER WITH APPLICATION TO UNSATURATED ZONE MONITORING AT L'EMPORDA, SPAIN
Enzyme Linked ImmunoSorbent Assay water sampling polyclonal antibodies
2009/10/19
A sensitive Enzyme Linked ImmunoSorbent Assay (ELISA) based on polyclonal antibodies was tested in a water sampling exercise at field scale. In the absence of deethylatrazine (DEA), results indicate t...
Uncertainty in river discharge observations：a quantitative analysis
river discharge quantitative analysis
2009/7/22
This study proposes a framework for analysing and quantifying the uncertainty of river flow data. Such uncertainty is often considered to be negligible with respect to other approximations affecting h...
Analysis and simulation of nutrient retention and management for a lowland river-lake system
nutrient retention lowland river-lake system European Water Framework Directive
2009/5/13
In the context of the European Water Framework Directive, we studied the possible impact of reduced emissions on phosphorus and nitrogen concentrations in a lowland river-lake system (Havel River, Ger...
Tracing and quantifying groundwater inflow into lakes using a simple method for radon-222 analysis
groundwater radon-222 analysis
2009/5/13
Due to its high activities in groundwater, the radionuclide 222Rn is a sensitive natural tracer to detect and quantify groundwater inflow into lakes, provided the comparatively low activities in the l...
The decreasing importance of acidification episodes with recovery from acidification：an analysis of the 30-year record from Birkenes, Norway
streamwater chemistry acid episodes
2009/4/29
The 30-year record 1975–2004 of weekly samples of streamwater chemistry from Birkenes, Norway, shows 106 acid episodes below the threshold of ANC−50 µeq l−1. The frequency, severity ...
