Module Overview Goal: Apply hydroinformatics skills to analyze climate impacts on hydrologic response and water system reliability in SLC Activities: Climate Data: CMIP5 Databases: MySQL and TOAD WEAP hydrologic modeling WEAP water management modeling Automation and Analysis using WEAP

Class 20 Learning Objectives Access climate change projection data Create a desktop database Load hydroclimate data in MySQL using TOAD Analyze climate data for trends and changes with Excel, TOAD, and MySQL

Climate Change BCCA CMIP3 Daily Climate Analysis example - Calendar-day, ensemble- mean change in 20-year diurnal temperature range Mean-Annual precipitation change (%), CMIP3, to

Why is Climate Change Important for Water Managers?

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: Variables: precipitation maximum temperature minimum temperature

Example

High-Resolution Climate Data With the CI-WATER project, we are increasing the horizontal resolution of climate model output from 100- km to 4-km using a physically-based regional model (WRF) with an explicit lake and urban irrigation scheme. Dr. Court Strong University of Utah

Accessing Climate Projection Data

Known facts in various types of text, graphics, images, sound and videos. Data

Manages data: saving, sorting, querying, processing, … Database

Collection of data stored and retrieved by database software. Definition, creation, querying, update, and administration of database Well-known DBMSs: MySQL, PostgreSQL, SQLite, Microsoft SQL Server, Oracle, SAP, dBASE, FoxPro, IBM DB2, LibreOffice Base and FileMaker Pro.MySQLPostgreSQLSQLiteMicrosoft SQL Server OracleSAPdBASEFoxProIBM DB2LibreOffice BaseFileMaker Pro  Database management systems (DBMSs): Data organization Facilitating data analysis Improving reproducibility and capacity for data re-use.

 SQL: a computer language for accessing data, both to store and to retrieve it. What is MySQL Supports use of SQL to access data A computer program to handle data - manage, store and find them as efficiently as possible Used by programs that run on websites World’s most popular open source relational database  MySQL

 A client/server system consists of a multi-threaded SQL server and supports different backends, several different client programs and libraries, administrative tools, and a wide range of application programming interfaces (APIs). MySQL Database Software MySQL client: main interface command line MySQL Server: server that responds to requests and commands MySQL Workbench: tool for database architects, developers, and DBAs MySQL products

 MySQL is a relational database management system that use SQL language. MySQL language Structured Query Language Used to communicate with a database Standard language for RDMSs Statements to update data on a database, retrieve data from a database, and more Standard SQL commands such as "Select", "Insert", "Update", "Delete", "Create", and "Drop" can be used to accomplish much that one needs to do with a database SQL

MySQL Server Setup  Creating an administrator password for MySQL  MySQL products installed on the computer  Full installation of MySQL

 Creating database in MySQL  Create a user burian is the Username and “burian" is the password

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

 Quickly create and execute queries  Automate database object management  Develop SQL code more efficiently  Compare, extract, and search for objects  Manage projects  Import/export data  Administer databases  Increase productivity  Access an active user community Toad helps to
