INS 352 E HYDROLOGY Spring 2018

Homework Assignment I

• 
  Deadline for HM-I is 6^th of April 2018.
  
• 
  The variable  is referred as the last two digits of the student ID in question 1 and the last digit of the student ID in question 2.
  
• 
  Improper collaboration will absolutely be punished (i.e. No cheating!)
  
• 
  The assignments should be submitted in an appropriate engineering format. Inappropriate formats will lead to a 25% decrease in the grading.
  

1. 
   The monthly water chart of a specific basin is given for a specific year. The area of the basin is (100+2 km² and the limit soil moisture is (150-) mm. Fill in the blanks of the table and calculate the monthly runoff volumes (The soil moisture at the beginning of the water year is assumed to be 0).
