Putting the rise of the Inca Empire within a climatic and land management context
Inca Empire land management context climatic
2009/12/3
The rapid expansion of the Inca from the Cuzco area of highland Peru (ca. AD 1400–1532) produced the largest empire in the New World. Although this meteoric growth may in part be due to the adoption o...
Integrated Nitrogen CAtchment model (INCA) applied to a tropical catchment in the Atlantic Forest, São Paulo, Brazil
Integrated Nitrogen in CAtchments atmospheric deposition rates hydrological conditions
2009/5/6
Stream-water flows and in-stream nitrate and ammonium concentrations in a small (36.7 ha) Atlantic Forest catchment were simulated using the Integrated Nitrogen in CAtchments (INCA) model version 1.9....
Eutrophication control in river-systems：an application of INCA-P to the River Lugg
Integrated Catchments model of Phosphorus dynamics river-systems River Lugg
2009/5/6
The Integrated Catchments model of Phosphorus dynamics (INCA-P) was applied to the River Lugg to determine the key factors controlling delivery of phosphorus to the main channel and to quantify the re...
This contribution brings to a close a special issue of Hydrology and Earth System Sciences concerning the assessment of nitrogen dynamics in catchments across Europe within a semi-distributed Integrat...
The Integrated Catchments model of Phosphorus dynamics (INCA-P), a new approach for multiple source assessment in heterogeneous river systems: model structure and equations
modelling water quality phosphorus
2009/3/17
A new model has been developed for assessing the effects of multiple sources of phosphorus on the water quality and aquatic ecology in heterogeneous river systems. The Integrated Catchments model for ...
A nitrogen model for European catchments: INCA, new model structure and equations
modelling water quality nitrogen
2009/3/17
A new version of the Integrated Nitrogen in Catchments model (INCA) was developed and tested using flow and streamwater nitrate concentration data collected from the River Kennet during 1998. INCA is ...
INCA Modelling of the Lee System: strategies for the reduction of nitrogen loads
modelling water quality nitrogen nitrate ammonium INCA
2009/3/17
The Integrated Nitrogen Catchment model (INCA) was applied successfully to simulate nitrogen concentrations in the River Lee, a northern tributary of the River Thames for 1995-1999. Leaching from urba...
Excess nitrogen leaching and C/N decline in the Tillingbourne catchment, southern England: INCA process modelling for current and historic time series
acid deposition recovery nitrogen Carbon-Nitrogen ratios
2009/3/17
Measurements of nitrate deposition and streamwater chemistry in the Tillingbourne Catchment, in Southern England, made in 1979-1982 and 1999-2001 show a 216% increase in Nitrogen leaching despite a r...
Modelling nitrogen dynamics and distributions in the River Tweed, Scotland: an application of the INCA model
Nitrate nitrogen modelling Tweed INCA
2009/3/17
The INCA (Integrated Nitrogen in Catchments) model was applied to the River Tweed in the Scottish Borders, a large-scale (4400km2), spatially heterogeneous catchment, draining a wide range of agricult...
Long-term modelling of nitrogen turnover and critical loads in a forested catchment using the INCA model
forest ecosystem N saturation critical load modelling
2009/3/17
Many forest ecosystems in Central Europe have reached the status of N saturation due to chronically high N deposition. In consequence, the NO3 leaching into ground- and surface waters is often substan...
N fluxes in two nitrogen saturated forested catchments in Germany: dynamics and modelling with INCA
forest ecosystem modelling N budgets N saturation NO3
2009/3/17
The N cycle in forests of the temperate zone in Europe has been changed substantially by the impact of atmospheric N deposition. Here, the fluxes and concentrations of mineral N in throughfall, soil s...
Hydrological application of the INCA model with varying spatial resolution and nitrogen dynamics in a northern river basin
northern river basin nitrogen forest management
