Efficient water management is essential for water and food security leading to socio-economic development. In order to build resilience and achieve water security, planning and management of water resources projects needs to be based on realistic assessment of related aspects. This requires comprehensive, reliable and easily accessible information on demand, availability and utilisation of water resources. Observational capabilities from ground monitoring systems and supplementary/complementary data from satellite remote sensing provide unique opportunities for data integration and value addition supporting water management decisions. While LANDSAT-1 initiated various remote sensing based activities with respect to management of hydrology and water resources across the globe, the launch of Indian remote sensing satellite, IRS-1A in 1988, along with its follow-up satellites, provided fillip to these activities mainly in India. The launch of IRS-1C in December 1995, with unique combination of sensors, has greatly improved extensive utilisation of satellite remote sensing for various facets of water management. This article presents a review of various applications carried out using IRS-1C data while highlighting the capabilities and advantage of IRS-1C sensors achieving significant improvement in mapping water bodies, inventory and monitoring of irrigated crops, irrigation system performance evaluation, assessment of reservoir sedimentation, mapping and monitoring of snow cover, snowmelt runoff forecasting, watershed developmental planning and management, etc.

IRS-1C 在印度水资源管理遥感应用开发中的作用

有效的水资源管理对于导致社会经济发展的水和粮食安全至关重要。为了建立复原力并实现水安全，水资源项目的规划和管理需要基于对相关方面的现实评估。这需要关于水资源需求、可用性和利用的全面、可靠和易于获取的信息。地面监测系统的观测能力和卫星遥感的补充/补充数据为支持水资源管理决策的数据集成和增值提供了独特的机会。虽然 LANDSAT-1 在全球范围内发起了与水文和水资源管理相关的各种基于遥感的活动，但 1988 年印度遥感卫星 IRS-1A 的发射，连同其后续卫星，为这些主要在印度开展的活动提供了动力。1995 年 12 月发射的 IRS-1C 具有独特的传感器组合，大大提高了卫星遥感在水资源管理各个方面的广泛利用。本文回顾了使用 IRS-1C 数据进行的各种应用，同时强调了 IRS-1C 传感器在水体测绘、灌溉作物清单和监测、灌溉系统性能评估、水库沉积评估等方面取得显着改进的能力和优势、积雪测绘与监测、融雪径流预测、流域开发规划与管理等。通过独特的传感器组合，大大提高了卫星遥感在水资源管理各个方面的广泛利用。本文回顾了使用 IRS-1C 数据进行的各种应用，同时强调了 IRS-1C 传感器在水体测绘、灌溉作物清单和监测、灌溉系统性能评估、水库沉积评估等方面取得显着改进的能力和优势、积雪测绘与监测、融雪径流预测、流域开发规划与管理等。通过独特的传感器组合，大大提高了卫星遥感在水资源管理各个方面的广泛利用。本文回顾了使用 IRS-1C 数据进行的各种应用，同时强调了 IRS-1C 传感器在水体测绘、灌溉作物清单和监测、灌溉系统性能评估、水库沉积评估等方面取得显着改进的能力和优势、积雪测绘与监测、融雪径流预测、流域开发规划与管理等。
