River velocity Measuring the velocity allows us to determine the speed‚ at which the river travels. If a high quantity of rain falls close to the source of the river there will be a greater amount of water travelling down stream and as a result the volume of water will be travelling at a higher speed. In the section of the river harbourne that that this measurement was taken in a high river velocity can indicate that Harbertonford is susceptible to flooding‚ a hazard that the flood defences

AMENDED 1966 KOSI TREATY AND 1997 KOSI STUDY AGREEMENT Dr. AB Thapa Summary: The 1966 Revised Kosi Treaty is a landmark treaty entitling Nepal absolute right to use the entire water of the Kosi in whatever way Nepal pleases. The amendment of the Kosi treaty from 99 to 199 years solely serves Nepal’s interest. There is no justification in blaming King Mahendra for this amendment to 199 years. The 1997 Kosi Study Agreement

Critical Analysis of Literature Review Reduction Technique of Water Evaporation Introduction When water evaporates from water storages it becomes a major issue that affects regions of agriculture in most lands leading to annual loss exceeding potentially to 40 precent and more of water storage. This water which is lost leads to reduction of productivity in agriculture affecting the environment adversely. Literature review has been developed on the same by various researchers

Geography Rivers 1. The speed and volume of a river varies from place to place along a river’s course because of many reasons. In the upper course‚ the volume of water is low as there are few tributaries. In comparison‚ the volume of water in the middle course is higher as there are more tributaries supplying water to the main river channel. The volume of water in the lower course is the highest as the lower course has the most tributaries. However‚ many other factors will also affect the

GEOHYDROLOGY HYDROLOGIC CYCLE The movement of water on the earth’s surface and through the atmosphere is known as the hydrologic cycle. Water is taken up by the atmosphere from the earth’s surface in vapour form through evaporation. It may then be moved from place to place by the wind until it is condensed back to its liquid phase to form clouds. Water then returns to the surface of the earth in the form of either liquid (rain) or solid (snow‚ sleet‚ etc.) precipitation. Water transport can also

The Effects of Physical Factors on the Storm Hydrograph The Storm Hydrograph refers to graphs that show how a drainage basin responds to a period of rainfall. Storm hydrographs are very important in predicting the flood risk and in making the necessary precautions to avoid damage to property and loss of life. Physical factors are the biotic factors which affect organisms and their surroundings‚ their surroundings in this case being the drainage basin and therefore the storm hydrograph is affected
