河道水位是洪水预报的关键变量,也是地表水资源供给能力的晴雨表。河道水位一般通过水文站实测,但由于全球水文站网密度稀疏,流域内存在大量的无河道水位观测断面,成为全流域精准防洪和水资源管理的硬件短板。测高卫星观测的水位数据可以覆盖全河道,这有力地提高了水位数据的空间代表能力。然而测高卫星要么空间分辨率太粗糙,无法识别小于80米的窄河道的水位;要么回访周期太长,无法探测河宽的关键时间变化节点。因此如何获...
Recently, in the year 2006, 2007 and 2008 heavy monsoons rainfall have triggered floods along Malaysia's east coast as well as in different parts of the country. The hardest hit areas are along the ea...
Water constitutes one of the sensitive environmental parameters of the hydrological processes. Therefore, the study of water resources exploitation sustainable to the environment is important. Water r...
Any reduction in water spread area at a specified elevation over a time period is indicative of sediment deposition at this level. This when integrated over a range of water stages helps in computing ...
A model is developed to understand the relationship between satellite-derived NDVI and rainfall data in a large tropical catchment. Two Fourier-based modeling techniques with a seasonal component, viz...
The paper discusses the applications of satellite remote sensing and GIS on characterization and spatial modeling of runoff and soil erosion of Birantiya Kalan, an arid watershed in the district of Pa...
Understanding how the land use change influence the river basin hydrology will enable planners to formulate policies to minimize the undesirable effects of future land use changes. Land cover changes ...
The Raniganj area has a long history of coal mining starting from 1744. This has resulted in major change in land use pattern and high groundwater abstraction leading to drinking water crisis especial...
The primary objective of this research involves mapping out and validating the existence of sub surface drainage tiles in a given cropland using Remote Sensing and GIS methodologies. The process is de...
Numerical models are important tools for simulating processes within complex natural systems, such as hydrodynamics and water quality processes within a water body. From decision makers’ perspectives,...
