Flood Ins

I. INTRODUCTION
The optimal use of water resources through conservation measures and appropriate management is critical in maintaining life support systems. The structure of water demand is shifting towards a gradual but steady growing pressure for drinking and other household and business needs in relation to the demand for irrigation, the new trend is to less water demanding perennial crops instead of seasonal crops. Progress in this direction is quite limited and the work of flood control continue to be on conventional lines, such as strengthening of embankments, construction of retaining walls, embankments,

He has not attempted in the past to assess the impact of floods, their intensity, pattern of occurrence and the vulnerability of different regions. Protection against flooding is possible only after identifying the cause of flooding from its origin. It is therefore proposed to organize a pool WISE in major river systems that are vulnerable to flooding, identify the causes of flooding and its intensity

Goal II:
It is the purpose of this document to promote public health, safety and general welfare and to minimize public and private losses due to flood conditions in specific areas by provisions designed:
A. To protect human life and health;
B. To reduce the expenditure of public funds for expensive projects of flood control;
C. To minimize the need for rescue efforts and emergency related to flooding and generally undertaken at the expense of the general public;
D. To minimize interruptions in working hours;
E. To minimize damage to public facilities and utilities such as water and gas mains, electricity, telephone and sewer lines, streets and bridges located in areas of special flood hazard;
F. To help maintain a stable tax base by providing for the use and development of the second areas special flood hazard to minimize future blight areas of flooding;
G. To ensure that potential buyers are notified that property is in an area of special flood hazard;
H. To ensure that those who occupy areas of special flood hazard assume responsibility for their actions.

III causes of flooding:
When it rains or snows, some water is retained by the soil, some is absorbed by vegetation, some evaporates, and the rest, which reached the river channels, is called runoff. Floods happen when soil and vegetation can not absorb any water, water, and then executes the earth in quantities that can not be transported in channels or kept in natural ponds and reservoirs constructed. About 30 percent of all precipitation runoff, and the masses of melting snow may increase this amount. Periodic floods occur naturally on many rivers, forming an area known as the floodplain. These river floods often result from heavy rain, sometimes combined with melting snow, causing rivers to overflow their banks and a flood that rises and falls rapidly with little or no notice is called a flash flood . Flash floods usually result from heavy rainfall on a relatively small area. Coastal areas are occasionally flooded by unusually high tides caused by strong winds on the ocean surface, or by tsunamis caused by earthquakes underwater These flood losses are caused by the cumulative effect of obstructions in areas of special flood risk, increasing flood heights and velocities, and when inadequately anchored, damage uses in other areas. Uses that are not adequately protected against flooding, elevation or other protection against floods also contributed to the loss of flood
IV EFFECTS OF FLOODING:
effects of flooding is not only property damage and endanger the lives of humans and animals, but also others. rapid runoff causes soil erosion and sediment deposition problems Dow.
