Document Summary
P(recipitaion +) = et (evapo-transpiraion -/-) + i(niltraion and groundwater low +) + r(unof +) + ^st (change in storage) Pore spaces between soil paricles or rock fractures are illed with water. Water lowing through earth iniltraion soil water, ground water. Water iniltrates due to gravity capillary acion (tension) draws molecules of water to ___ Wherever water table intersects surface there will be a spring or stream. Porosity is the percentage of the volume of the rock or sediments that is open space (pore space) Iniltraion rate at the beginning of a storm is high but low at the end of a storm. Saturaion of soil causes this at the beginning of storm the soil is empty at the end it is full of water. Hydraulic head gradient: q (lux of water) = a(rea that"s contribuing the water) k (hydraulic conducivity) ^hl (height change between source and sink) ^l (length change between source and sink)
