Guidelines for solving quantitative problems One of my goals for this course is to help those students that are not comfortable with quantitative problems improve their problem solving skills and gain confidence.
Determining Average Precipitation Over Large Areas There are many ways to interpret and analyze precipitation data recorded at stations throughout the world. Weather folks like us aren't the only ones interested in precipitation! Engineers and hydrologist
Introduction In 1856, Henry Darcy, a French hydraulic engineer, published a report in which he described a series of experiments he had performed in an attempt to quantify the amount of water that would flow through a column of sand. The experimental appa

Chapter 2 Fluid Potential and Kinetic Energy Introduction
One of the fundamental equations that govern groundwater flow is called Darcys Law (equation 2-1),
Q = K A dh/dl
where: Q = discharge [L3/T] A = cross sectional area [L2]

Introduction
In the last chapter we discussed equations and introduced the main groundwater flow equation, which is:
q x q y q z h + + = Ss x y z t
where q = specific disch

Groundwater
The strict technical definition of groundwater is any water that is found beneath the surface of the Earth. This definition includes
a) The moisture that is found in the pores between soil grains b) The fresh to slig

A water budget is an attempt to follow the water or account for the movements and transformations of water in a watershed or region.

If the precipitation rate does not exceed the equilibrium infiltration capacity (Figure 15-8A), all the precipitation reaching the land surface will infiltrate and there will be no runoff. If the precipitation rate is greater th
