Water legislation in Japan in perspective of hydropower development

Water legislation in Japan in perspective of hydropower development

Japan is rich in water resources. The average annual precipitation is about 650 billion m3, out of which 420 billion m3 is the theoretical maximum that can be utilized for various purposes including hydropower generation. In 1951, the electricity business of Japan was handed to 10 regional power utilities. In 1995, the independent power producer (IPP) were allowed to sell electricity. According…

Cobweb plot

While conducting multi variable analysis, it may be useful to see how the output changes due to change in inputs. For example humidity, temperature and water-level may change the deflection of dam. Cobweb plot combined with normal distribution will help to visualize the risks easily. An example of such plot is shown below.

An octave (or matlab) code to generate such plot is given below.…

Evolution and entropy

Eary morning psyco-syndrome.

Once born we slowly evolve physically by gaining tissues and bones. The food we eat is transformed into the machinaries of body. This indicates that the entropy or randomness decreases over time to create a useful thing. But once we cross certain age decay starts and the biological machinaries starts to disfunction. It seems decay and dissolution is the final…

Specific gravity of soil particles

Specific gravity of soil particles

Consider the following figure.

W1= weight of empty vessel W2= Weight of vessel + weight of sample W3=Weight of vessel + weight of sample+Water W4=Weight of vessel + Water

Here, Weight of solid = W2-W1

Similarly, from last two figures W3-W4=Weight of solid- Weight of water or, W3-W4= W2-W1 -Weight of water or, weight of water=(W2-W1)-(W3-W4)(= weight of equal volume of water as that of solid)
