Using model reduction to predict the soil-surface C18OO flux: an example of representing complex biogeochemical dynamics in a computationally efficient manner
Using model reduction predict the soil-surface C18OO flux representing complex biogeochemical dynamics computationally efficient manner

Earth system models (ESMs) must calculate large-scale interactions between the land and atmosphere while accurately characterizing fine-scale spatial heterogeneity in water, carbon, and other nutrient...
Enrichment of Phosphate on Ferrous Iron Phases during Bio-Reduction of Ferrihydrite
Phosphate Iron Reduction Ferrihydrite Ferrous Iron Vivianite
2013/3/7
The reduction of less stable ferric hydroxides and formation of ferrous phases is critical for the fate of phosphorus in anaerobic soils and sediments. The interaction between ferrous iron and phospha...
Payment schemes for hydrological ecosystem services as a political instrument for the sustainable management of natural resources and poverty reduction – a case study from Belén, Nicaragua
Payment schemes hydrological ecosystem services a political instrument for the sustainable management of natural resources poverty reduction – a case study
2010/9/10
The importance of intact ecosystems for human-wellbeing as well as the dependence on functions and services they provide is undoubted. But still neither the costs of ecosystem degradation nor the bene...
Chronic nitrogen addition causes a reduction in soil carbon dioxide efflux during the high stem-growth period in a tropical montane forest but no response from a tropical lowland forest on a decadal time scale
Chronic nitrogen addition soil carbon dioxide efflux the high stem-growth period a tropical montane forest a tropical lowland forest
2010/1/21
Atmospheric nitrogen (N) deposition is rapidly increasing in tropical regions. We studied the response of soil carbon dioxide (CO2) efflux to long-term experimental N addition (125 kg N ha−1 yr&...
Use of the event tree to assess the risk reduction obtained from rockfall protection devices
event tree risk reduction rockfall protection devices
2010/1/4
The paper presents and discusses a procedure for the evaluation of the collective risk that can affect a road subjected to rockfalls, with and without protection measures, by means of the event tree a...
The critical role of volcano monitoring in risk reduction
critical role volcano monitoring risk reduction
2010/1/27
Data from volcano-monitoring studies constitute the only scientifically valid basis for short-term forecasts of a future eruption, or of possible changes during an ongoing eruption. Thus, in any effec...

2010/1/27
The implementation of the EU Water Framework Directive (EU-WFD) forms the background of the WAgriCo-project (Water Resources Management in Cooperation with Agriculture). WagriCo concentrates on the de...
Data management and GIS in the Center for Disaster Management and Risk Reduction Technology (CEDIM):from integrated spatial data to the mapping of risk
Data management GIS Disaster Management Risk Reduction Technology (CEDIM)

The project "Risk Map Germany" of the Center for Disaster Management and Risk Reduction Technology (CEDIM) aims at the examination of existing and the development of new approaches for integrated risk...
On the use of radar reflectivity for estimation of the areal reduction factor
use of radar reflectivity estimation areal reduction factor
2009/12/29
In order to estimate the rainfall fields over an entire basin raingauge, pointwise measurements need to be interpolated and the small-scale variability of rainfall fields can lead to biases in the rai...
Flood loss reduction of private households due to building precautionary measures--lessons learned from the Elbe flood in August 2002
Flood loss reduction private households building precautionary measures
2009/12/25
Building houses in inundation areas is always a risk, since absolute flood protection is impossible. Where settlements already exist, flood damage must be kept as small as possible. Suitable means are...
