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.
基于美国地质调查局的软件MODFLOW 2000（包括用于河流流量路由的SFR2软件包）构建了奥卡万戈三角洲地表水-地下水耦合模型。它将为评估水资源管理和气候变化情景提供一个新工具。三角洲面积大且可达性有限，使得直接在实地获取数据变得困难。遥感方法是获取模型输入参数和校准所需空间分布数据最有前景的来源。地形、含水层厚度、河道位置、蒸发散和降水数据均基于遥感。将模拟洪水模式与从可见光到热红外的美国国家海洋和大气管理局高级甚高分辨率辐射计（NOAA-AVHRR）数据以及微波雷达欧洲环境卫星先进合成孔径雷达（ENVISAT-ASAR）数据得出的模式进行比较。
