they over flow
water inland usually drain into sea through rivers if there is to much rain the rivers and canals gets overflooded
A Floodtide can come over night and cover all of the dry land. or, Rivers flood because snow melts and dams burst and heavy rain, all these can cause the water level to rise and this can cause floods.
Catchment area. All the land where rain falls and runs into rivers and dams.
Electricity generated for dams is renewable because the Sun does the heavy lifting of evaporating the water from seas and lakes so it can fall back to the ground as rain and swell rivers again. Tidal dams use the gravity of the Moon, which is constant.
we can preserve rainwater in various types. We can preserve rainwater in dams,seas,rivers,lakes etc..,.we can can drink rain water by purifing the rainwater.we can preserve rain water in bucketsetc..,in our homes.Donot waste the rain water that water will useful for us later.
The amount of rain fall feeding the river. The slope of the riverbed. The placement of weirs and dams, and the natural obstruction caused by boulders impeding the flow.
Streams and rivers can usually cope with excess rain. However, after a prolonged period of heavy rain, rivers sometimes burst their banks and flooding occurs.
There is every liklihood of flood in case of heavy rain, when the low lying areas are submerged in rain waters and the water dams are forced to relase excess water stored above the optimum level.
A flood happens when water over flows from to much rain and over flows the city/village/etc........ also, when it rain for so long and rain so hard
grass grows (I am from Texas)
yes..but it doesn't rain much. Water is shipped or they use rivers
If there is no rain, then a dam does not help.
