Water Resources/Science - The Colorado River water has an EC of 1.25 dS/m

Please see the attached questions. 1. The Colorado River water has an EC of 1.25 dS/m (1 dS/m is approximately equivalent to 700 mg/l). Calculate how much salt is added to a field of 1 Ac during a year if the total irrigation for crop production for the year is 5 ft (hint: unit conversion!). 2. The rainfall intensity during a 9-hour period is 6 mm/hour (constant). The soil infiltration rate can be described by i (mm/h) = 2 t-0.5 + 4.0 (where t is in hour) Estimate the total runoff during the 9-hour period (hint: runoff only occurs after the surface is under ponding. Time of ponding is calculated by setting infiltration rate equal to rainfall intensity). 3. A reservoir with ... click for more

Revised Universal Soil Loss Equation (RUSLE)

The Revised Universal Soil Loss Equation (RUSLE)has many factors to it. The equation is A=RK(LS)CP. Based on this equation would the following below DECREASE or INCREASE: A. Increasing the length of the hillside (going down) will ____ erosion B. Increasing the slope of the hillside will _____ erosion C. Poor crop/lawn management such as soil left bare will ___ erosion.
