Document Summary
Lecture 2 hydrological concepts & physical properties of. Outlet = portion of water exiting watershed. Water shed divide will go right through hill top. Valley = curvature on contour lines point to higher topographic position. Ridge = curvature on contour lines point to lower topographic position. Along ridges or curvature = water shed area. Point down gradient = ridge into stream outlet. At regional scale, watershed very useful in consideration of water balance (m^3 divided by m^2 = m^3-2 = m) (m x m^2 = m^1+2 = m^3) If weatherperson says 14mm of rain fell last night: Point where they took measurement = 14mm (spatial variation) Spatial refers to changes over space. Temporal refers to changes over time. Variability inherent characteristic of all natural systems. Precipitation over large watershed due to convective storms. Difficult to get handle on unless lots of sampling done.
