Hydrology Definition and 11 Threads

I live on a lake, and have for almost 3 decades now. Every year I watch shoreline changes, from year to year and shorter timespans, sometimes just days. The lake is large in surface area at 236 km2 (91 sq mi), but with an average depth of only 28' probably relatively small in volume for its...

Hi guys, not sure if anyone can help me but I'm having a bit of an issue with creating a storm hydrograph from a 60 min unit hydrograph that is in 5 minute intervals. I've lagged the unit hydrograph by 60 minutes each net rainfall block while multiplying the respective net rainfall to the...

Homework Statement Lag time in hydrograph means teh time of center of rainfall to center of hydrograph , according to my book . Homework EquationsThe Attempt at a Solution Since lag time can be understood by the time taken for the water to reach river , contributing to max discharge ... So ...

Homework Statement Develop a hydrograph (rainfall intensity vs time) for the precipitation data . Then , estimate the amount of gauge X if there adjacent station precipitation amount of A , B and C are 42.4 , 35.3 and 38.4 respetively . Homework EquationsThe Attempt at a Solution So , i...

Homework Statement A watershed with a surface area of 3100km^2 received 170cm of precipitation during a one year period . Durign the same year , the outflow was 50(m^3)/sec .Calculate the amount of water lost due to combined effects of evaporation , transpiration and infiltration. Also estimate...

Homework Statement I have problem of obtaining the cross sectional area . Homework EquationsThe Attempt at a Solution Taking section 2-3 as an example , my working is [ (3.3 +4.8) / 2 ]* 5 = 20.25 , but the ans provided is 29.28 , how to get the 29.28 ?

Homework Statement In my book , i was told that when the drainage of surface is high then the surface runoff will be low . However , i don't think it's correct . Homework EquationsThe Attempt at a Solution Definiton : Runoff can be described as the part of the water cycle that flows over...

Hello, I am working with the mass flow rate equation which is:$$\frac{d \dot{m}}{dt}=\dot{m}_{in}-\dot{m}_{out}$$ To determine the change of the height of water in a reservoir. Assuming m_in = 10 and m_out = sqrt(20h), then : $$\frac{d (\rho \cdot Q) }{dt}=\rho \cdot Q_{in} - \rho\cdot...

Hello there! This is my first time posting, but I'm a long time reader. I could not find a more appropriate sub-forum. I have just been hired to compile and organize data for an arctic hydrology research project in Fairbanks, AK. They are studying climate change and have recorded a few...

Hi. I'm 25 years old with a wife and two sons. I've spent the last two years after graduation teaching at an academy in Taipei, Taiwan. While over there I decided I no longer wanted to teach English and that I wanted to get into hydrology. Why hydrology? Several reasons. I used to...

Does anybody knows of a good hydrology book?? I am a civil engineering student, i want mostly applied stuff and at the undergraduate level.
