Impact of Climate Change
on Water Resources
University of Utah
Hydroinformatics - Fall 2015
Module Overview
• Goal: Analyze climate impacts on hydrologic
response and water system reliability in SLC
• Activities:
•
•
•
•
•
•
Climate Data: CMIP5
Databases: MySQL and TOAD
Change factor module in R
WEAP hydrologic modeling
WEAP water management modeling
Automation and Analysis using WEAP
Learning Objectives
• Describe global climate change modeling and
downscaling
• Access CMIP5 data archive
• Create a local database and generate SQL script with
TOAD
• Write a statistical downscaling method, change factor
approach, in R
• Generate future precipitation based on climate change
models
Climate Change
Mean-Annual precipitation change,
percent CMPI3, 1970-1999 to 20402069, 50%tile
BCCA CMIP3 Daily Climate Analysis
example - Calendar-day, ensemble-mean
change in 20-year diurnal temperature
range
Why Climate Change is
important for water managers?
Average water available
average use
Future use?

General Circulation Models
• Numerical models representing physical processes in the
atmosphere, ocean, cryosphere and land surface
• Most advanced tools
currently available
• Three dimensional grid
• Their resolution is
quite coarse to evaluate the
impact on water resources

Coupled Model Intercomparison
Project phase 5 (CMIP5)
• Archive of fine spatial resolution of climate projections over
US.
• Updated archive, May 2013:
• 234 projections of monthly data
• 134 projections of daily data
• Resolution: 1/8° latitude-longitude (~12km by 12 km)
• Time Coverage: 1950-2099
• Variables:
• precipitation
• maximum temperature
• minimum temperature

Toad for MySQL
 A freeware development tool for the management of a MySQL
database.
 Rapidly create and execute queries, automate database object
management, and develop SQL code more efficiently.
 Provides utilities to compare, extract, and search for objects;
manage projects; import/export data; and administer the
database.
 Dramatically increases productivity and provides access to an
active user community.

Next session
• Create a hydrologic model and water supply system model in
WEAP
• Download and install WEAP before the class
• Homework #9:
Complete the Change Factor approach code in R. At the end will
present graphs to compare the change factors for two stations
(Parleys and Airport), three time slices of 2010-39, 2040-69, and
2070-99, and four emission scenarios.
