Modeling and Understanding the Relationship between Vegetation and Rainfall of a Tropical Watershed using Remote Sensing Data and GIS
NDVI rainfall modelling calibration verification
font style='font-size:12px;'>
2015/1/7
A model is developed to understand the relationship between satellite-derived NDVI and rainfall
data in a large tropical catchment. Two Fourier-based modeling techniques with a seasonal
component, v...
Climatology-based regional modelling of potential vegetation and average annual long-term runoff for Mesoamerica
Climatology-based regional modelling potential vegetation long-term runoff Mesoamerica

2010/12/22
Mean annual cycles of runoff, evapotranspiration, leaf area index (LAI) and potential vegetation were modelled for Mesoamerica using the SVAT model MAPSS with different climatology datasets. We calibr...

In the past years there have been many attempts to produce and improve global soil-moisture datasets and drought indices. However, comparing and validating these various datasets is not straightforwar...
The Plynlimon water balance 1969-1995：the impact of forest and moorland vegetation on evaporation and streamflow in upland catchments

2009/6/8
The Plynlimon experiment in mid-Wales, designed to determine the extent to which coniferous plantation increases evaporation losses and reduces streamflow relative to upland grassland, has now been yi...
Eco-geomorphology of banded vegetation patterns in arid and semi-arid regions

2009/5/13
The interaction between vegetation and hydrologic processes is particularly tight in water-limited environments where a positive-feedback links soil moisture and vegetation. The vegetation of these sy...
Analysis of effective resistance calculation methods and their effect on modelling evapotranspiration in two different patches of vegetation in semi-arid SE Spain

2009/5/13
Effective parameters are of major importance in modelling surface fluxes at different scales of spatial heterogeneity. Different ways to obtain these effective parameters for their use in meso-scale ...
Implications of changing from grazed or semi-natural vegetation to forestry for carbon stores and fluxes in upland organo-mineral soils in the UK
semi-natural vegetation carbon stores upland organo-mineral soils
font style='font-size:12px;'>
2009/5/6
In the UK, as organo-mineral soils are a significant store of soil organic carbon (SOC), they may become increasingly favoured for the expansion of upland forestry. It is important, therefore, to asse...
A conceptual dynamic vegetation-soil model for arid and semiarid zones

font style='font-size:12px;'>
2009/5/6
Plant ecosystems in arid and semiarid climates show high complexity, since they depend on water availability to carry out their vital processes. In these climates, water stress is the main factor cont...
Estimation of vegetation cover resilience from satellite time series

font style='font-size:12px;'>
2009/5/4
Resilience is a fundamental concept for understanding vegetation as a dynamic component of the climate system. It expresses the ability of ecosystems to tolerate disturbances and to recover their init...
