Luckily it's in winter when the trees are dormant so not expecting any long term damage. However it delays the winter pruning. The ground is to wet to work on without destroying the grass sward. Role on Spring. #perry #pear #tree #orchard

Problem: Using the data from problem 1.9, what is the runoff coefficient? Solution: The following are given: \begin{align*} \text{Area}, A & = 2500 \ \text{km}^2 \\ \text{Precipitation}, P & = 130\ \text{cm} \\ \text{Outflow}, O & = 30\ \text{m}^3/\text{s} \end{align*} To compute for the runoff coefficient, the formula to be used is \text{runoff coefficient} =…

Problem: In a given year, a watershed with an area of 2500 km2 received 130 cm of precipitation. The average rate of flow measured in a gage at the outlet of the watershed was 30 m3/sec. Estimate the water losses due to the combined effects of evaporation, transpiration, and infiltration due to ground water. How much runoff reached the river for the year (in cm)? Solution: The following are…

Problem: In a given month, a watershed with an area of 1500 m2 received 100 cm of precipitation. During the same month, the loss due to evaporation was 15 cm. Ignore losses due to transpiration and infiltration due to ground water. What would be the average rate of flow measured in a gage at the outlet of the watershed in m3/day? Solution: We are given the following…
