Managing water resources is a critical challenge in the mountain and hill regions of the Hindu Kush Himalaya (HKH). Not only is demand increasing – for domestic use, irrigation, industry, and energy –
Flood Hazard Mapping is a vital component for appropriate land use planning in flood-prone areas. It creates easily-read, rapidly-accessible charts and maps which facilitates the administrators and planners to identify areas of risk and prioritize their mitigation/ response efforts. This article presents an efficient methodology to accurately delineate the flood-hazard areas in the Kosi River Basin, North Bihar, India in a GIS environment.
The main objective of this study can be asserted as to assess the probable impacts, which are likely to be happened due to the operation of proposed Tipaimukh Hydro Electric Dam (Multipurpose) Project of India by storing, regulating, withdrawal or diversion of the Barak River flow on the northeast region of Bangladesh.
Flood hazard in a basin depends upon the hydrological response of the upstream basin area. The upstream basin area may produce different amounts of run-off for a given rainfall based on its hydrologic response. The present communication shows the importance of drainage network characteristics in understanding the hydrologic response of a basin. The study is carried out through Geomorphic Instantaneous Unit Hydrograph analysis, wherein Horton's morphometric ratios were used to define the drainage network. A floodprone river basin in north Bihar plains has been selected as a study area.
Flood hazard is one of the most severe problems in the Himalayan river basins. Although floods are essentially hydrological phenomenon, the uneven distribution of floods in the river basin highlights the
Lack of coherent research on the melting Gangotri glacier spells disaster
Increasing concentrations of atmospheric carbon dioxide will almost certainly lead to changes in global mean climate. But because - by defnition-extreme events are rare, it is significantly more difficult to quantify the risk of extremes.
Radiative effects of anthropogenic changes in atmospheric composition are expected to cause climate changes, in particular an intensification of the global water cycle with a consequent increase in flood risk.
<p>Water has suddenly become a favoured subject for seminars and conferences all over the world.
Ever since the inception of Bangladesh in 1972 its politics have been featured by several types of seemingly endemic conflict, some of which have been associated with either periodic outbursts of violence
<p>The basin area of the Ganges river in Bangladesh is extremely dependent on a regular water supply from upstream to meet requirements for agriculture, fisheries, navigation, salinity control, domestic and industrial sectors. In 1975 India commissioned a barrage on the Ganga river at Farakka to divert significant portion of the dry season flow in order to make the Calcutta port navigable.
