PracticalProfileofSpillwaY
When the profile for the crest of the ogee spillway is plotted over the triangular profile the section of a gravity dam (non-overflow section) ,it is found that it goes beyond vie downstream face of the dam , thu requiring thickening of the section for the spillway .
However,this extra concrete can be saved by shifting the curve of the nappe in a backward direction until this curve becomes tangential to the downstream face of the dam .
Design of spillway
Design an ogee spillway for concrete gravity dam, for the following data :
(1) Average river bed level = 100.0 m
(2) R.L. of spillway crest =204.0 m
(3) Slope of d/s face of gravity dam = 0.7 H : 1 V
(4) Design discharge = 8000 cumecs
(5) Length of spillway = 6 spans with a clear width of 10 m each.
(6) Thickness of each pier = 2.5 m
If h/Hd is greater than 1.7 than high spillway so effect of velocity is neglected
The co-ordinates from x = 0 to x = 27.4 m are worked out in the table below :
This study explains the use of remote sensing data for spatially distributed hydrological modeling using the MIKE-SHE software used in Tarim River Basin CHINA

Dr. Jared Buono, Hydrologist at Gram Pari talks about how Groundwater recharge and Spring Revival can go hand in hand. It can supply clean drinking water and mobilize community at the same time.

Atividade para a reflexão sobre a relação entre água e sociedade. Uma das agendas globais da ONU é o controle sobre os recursos hídricos das comunidades locais. Através de discursos catastróficos sobre a extinção da água potável, a ONU elabora normas e princípios para modificar a percepção de populações inteiras sobre o uso da água.
