Description:

The role of remote sensing in hydrological modelling of the Okavango Delta, Botswana.

Summary / Notes:

A coupled surface water–groundwater model of the Okavango Delta has been built based on the United States Geological Survey software MODFLOW 2000 including the SFR2 package for stream-flow routing. It will provide a new tool for evaluating water management and climate change scenarios. The delta's size and limited accessibility make direct, on the ground data acquisition difficult. Remote sensing methods are the most promising source of acquiring spatially distributed data for both model input parameters and calibration. Topography, aquifer thickness, channel positions, evapotranspiration and precipitation data are all based on remote sensing. Simulated flooding patterns are compared to patterns derived from visible to thermal NOAA-AVHRR data and microwave radar ENVISAT-ASAR data. Keywords: Okavango Delta, Integrated hydrological modelling, Surface water–groundwater interaction, Remote sensing, Wetland.
