低分辨率气象卫星数据和简单的照片判读技术已被用于绘制4月初巴基斯坦印度河和喀布尔河流域积雪覆盖区的地图。早春积雪面积显着相关的4月1日至7月31日流量回归分析为每个流域（印度河，1969-1973年，r2 = 0.82，喀布尔河，1967-1973年，r2 = 0.89）。使用回归方程对1974年季节性径流量的预测在1974年实际流量的7%以内。由于水文气象数据不足，在其中一些偏远地区无法进行传统的径流预测，而从卫星获得的径流估计可立即用于改善水资源管理。
Low-resolution meteorological satellite data and simple photo interpretation techniques have been used to map snow-covered areas during early April over the Indus River and Kabul River basins in Pakistan. The early spring snow-covered area was significantly related to April 1 through July 31 Streamflow in regression analyses for each watershed (Indus River, 1969–1973, r2 = 0.82, and Kabul River, 1967–1973, r2 = 0.89). Predictions of 1974 seasonal Streamflow using the regression equations were within 7% of the actual 1974 flow. Because of inadequate hydrometeorological data, conventionally based Streamflow predictions are not possible in some of these remote regions, and the satellite-derived runoff estimates have immediate applicability for improved water resources management.
