Hydrus (2007)

 

The University of Hawaii-Manoa Natural Resources and Environmental Management Department, and Water Resources Research Center organized a HYDRUS 3D workshop during November 12- 13 2007 in Honolulu. Training was at the University of Hawaii-Manoa. Thank you to all of those who attended!

 

Turfgrass Irrigation Management Practices, Maui, Hawaii (2005)

 

This program is designed to help workers who provide landscape services for hotels, condominiums, golf courses, and other private and public landscape areas and right-of-ways. It will allow these properties to better manage their water use and reduce the costs associated with landscape irrigation. It will also help to conserve Maui County’s valuable water resources.

 

A series of three irrigation workshops are being proposed for the landscape and turfgrass industries on the islands of Maui, Molokai, and Lanai. The first two sessions will be held on March 28 and April 25 in a television studio at Maui Community College’s Ka‘a‘ike Building, which will be transmitted to their respective classroom studios on Molokai and Lanai. The third session will be held outdoors as a field demonstration on MCC’s campus on May 30. Each session will last approximately 3-1/2 hours.

 

Dr. Ali Fares an assistant professor in hydrology & tropical soils in the Department of Natural Resources and Environmental Management, College of Tropical Agriculture and Human Resources, University of Hawaii at Manoa will be teaching these sessions.

  • Session 1: “Soil-Water-Plant Relationships and Their Impact on Irrigation and Water Management.” This workshop will help participants understand the basics about soils, the impact of their physical properties on irrigation, plant’s water requirements, and factors affecting it.
  • Session 2: “Irrigation Systems and Irrigation Scheduling.” The second workshop will cover the major irrigation systems, their advantage and disadvantages, and where they can be appropriately used.
  • Session 3: Field demonstrations of various irrigation systems, water auditing, and water conservation device.

A registration fee of $25.00 will be charged to participants to help sustain the landscape/turf educational programs.

 

Controlling Water Contaminants at the Source by Integrated Technologies,

Kaiaka-Waialua Watershed, Oahu (2005)

 

You are invited to join us as we share the results of our research using grass cover crops as a means to manage nutrients in bare ground fallow cropping systems. We are also examining the effects of the cover crops on weed control. Refreshments will be provided and a good time is guaranteed to be had by all!

  • WHERE: Waialua, North Shore, Oahu 
  • WHEN: Monday, May 16, 2005, 9:00 a.m. – noon
  • WHAT: Demonstration of Different Cover Crops (Oats, Sunn Hemp and Sudex) to protect soil from erosion and improve water infiltration.
  • WHO: University of Hawaii, Crop Care Hawaii, Waialua High School, and Pioneer Hi-Bred International, Inc.

FUNDED BY: U. S. Environmental Protection Agency and the Hawaii State Department of Health, Clean Water Branch under Section 319(h) of the Clean Water Act and University of Hawaii, College of Tropical Agriculture and Human and Resources, Sustainable Agriculture Research and Education.

Hydrus Workshop (2005)

 

The University of Hawaii-Manoa Natural Resources and Environmental Management Department, and Water Resources Research Center are organizing a HYDRUS workshop during June 30 - July 1 2005 following the American Water Resources Association Summer Specialty conference, June 27-29 2005 at the Hyatt Regency Waikiki Resort & Spa, Honolulu, Hawaii.

 

The workshop begins with a detailed conceptual and mathematical description of water flow and solute transport processes in the vadose zone, followed by an overview of the use of finite element techniques for solving the governing flow and transport equations. Special attention is given to the highly nonlinear nature of the governing flow equation. Alternative methods for describing and modeling the hydraulic functions of unsaturated porous media are also described.

 

"Hands on" computer sessions will provide participants an opportunity to become familiar with the Windows based RETC, STANMOD, HYDRUS 1D and HYDRUS 2D software packages. Emphasis will be on the preparation of input data for a variety of applications, including flow and transport in a vadose zone, variably saturated flow through a dam, flow and transport to a tile drain, and two dimensional leachate migration from a landfill through the unsaturated zone into groundwater. Calibration will be discussed and demonstrated using both one and two dimensional model inversions.
