Indicators of desiccation-driven change in the distal Okavango Delta, Botswana
(Elsevier Ltd; www.elsevier.com/locate/jaridenv, 2007-01)
This work seeks to determine whether riparian woody plant variables respond to drying and salinity regimes in the semi-arid distal Okavango Delta, northern Botswana. Structural and compositional variables were obtained ...
Vegetation cover trends along the Botswana Kalahari transect
(Elsevier; www.elsevier.com/locate/jaridenv, 2003)
Vegetative response aspects of climate change studies include the determination of vegetation cover changes across climatic gradients. Vegetation characteristics and soil moisture measurements were obtained from four ...
Temperature-Emissivity separation with ASTER and LANDSAT 7 validation on the fringe of the Okavango Delta, Botswana
(SPIE, http://link.aip.org, 2004)
Land surface temperatures are important in global change studies, in estimating radiation budget, heat balance studies and as control for climate models. Several algorithms for estimating land surface temperature and ...
Scenarios of the impact of local and upstream changes in climate and water use on hydro-ecology in the Okavango Delta, Botswana
(Elservier, www.elsevier.com, 2006)
Changes in hydrological inputs to the flood-pulsed Okavango Delta result in changes in such flooding characteristics as floodplain water depth, inundation duration and frequency. A mathematical model is used to assess ...
Aquatic ecosystem responses to fire and flood size in the Okavango Delta: observations from the seasonal floodplains
(Springer, http://www.springer.com, 2010-07-19)
The frequency of fires in the Okavango Delta seasonal floodplains peaked at an intermediate frequency of flooding. Floodplains are commonly burnt every 3–5 years. This study showed fundamental changes in ecosystem properties ...
Tropical wetlands: seasonal hydrologic pulsing, carbon sequestration and methane emissions
(Springer, http://www.springer.com, 2010)
This paper summarizes the importance of climate on tropical wetlands. Regional hydrology and carbon dynamics in many of these wetlands could shift with dramatic changes in these major carbon storages if the inter-tropical ...
Islands in the Okavango delta as sinks of water-borne nutrients
(Botswana Society, 2005)
Groundwater under islands in the Okavango Delta is a known sink of inorganic dissolved minerals, preventing salinisation of this virtually enclosed evaporation-dominated hydrological system. The Okavango Delta is an ...
Simulation of DOM fluxes in a seasonal floodplain of the Okavango Delta, Botswana
(Elsevier, www.elsevier.com/locate/ecolmodel, 2007)
In order to examine dissolved organic matter (DOM) fluxes in seasonal wetland systems
that expand and contract seasonally, a time-variable model of dissolved organic carbon
(DOC) was developed for a seasonal floodplain ...
Aspects of seasonal dynamics of flooding in the Okavango delta
(Botswana Society, 2005)
Seasonal changes in inundation area and peak flood occurrence in the Okavango Delta are analysed using a multiple regression technique. The multiple regression models developed constitute useful and simple tools for ...
Flooding dynamics in a large low-gradient alluvial fan, the Okavango delta, Botswana, from analysis and interpretation of 30-year hydrometric record
(Hydrology and Earth Systems Sciences, www.hydrology-and-earth-system-sciences.net, 2006)
The Okavango Delta is a flood-pulsed wetland, which supports a large tourism industry and the subsistence
of the local population through the provision of ecosystem services. In order to obtain insight into the influence ...
