Fall 2006 NREM662: Watershed Hydrology
Class/laboratory Schedule
Meetings: Tuesdays 3:00 – 4:15 p.m. & Thursdays 3:00 – 5:00 p.m. Agricultural Sciences 215
Instructor:
Dr. Ali Fares,
Associate Professor of Watershed Hydrology
Office: 242 Sherman Laboratory. Phone:956-6361Email:AFares@Hawaii.Edu

Course Objectives:
 This course will provide students with a fundamental understanding of the hydrologic cycle, the interactions
among the hydrosphere, atmosphere and land-use management (forest, agriculture and urban) effects on the
amount, timing and quality of water resources.
 Develop the ability to quantify the magnitude of hydrologic entities in small watersheds. They will have some
hands on hydrologic analysis in watershed management such as rainfall, effective rainfall, canopy interception,
evapotranspiration, infiltration, stream flow and hydrographs
o Understand the rainfall-runoff-stream flow relationship
o Relate hydrologic information to land use management. Students will study impact of different
management practices on natural resources.
o Understand impact of different watershed management on hydrology, water quality of the surface and
groundwater resources, and flooding.
Required Textbook: Hydrology & the Management of Watersheds by Brooks et al. 3rd Edition, Iowa State Press.

E-mail and Web Page: Students need to check their e-mails and the web page of the course frequently, for they will
be used to keep informed of any important changes or additions.
Participation: Attendance and participation in class are required. If you miss class, you are responsible for finding
out (from other students) missed material and/or assignments.
Project: You are to complete a research project during the course of the course. You can choose a field or a
laboratory experiment. You can also conduct a literature review or a modeling exercise using one of the watershed
models (WMS, N-SPECT, and AnnAGNPS). The project deliverables will consist of
1. Project proposal (1 or 2 Pages)
Due September 29th 2006
2. The literature review
November 3rd 2006
3. Final version of manuscripts
Due Friday December 1st 2005
4. 15 min presentation
Last week of classes
You may choose any topic related to watershed hydrology. It is recommended to choose a topic of interest to you or
related to your research. You may utilize publicly available data sets for analysis (USGS, NOAA, HI-DLNR etc…)
Grading:
Grades will be based on a minimum of 90% (A), 80% (B), 70% (C), 60% (D).
The weighting is as follows: Midterm 30%, Homework & Lab Rep 30%, Project 30%, Participation 10%
Labs/Homeworks:
1- Watershed delineation; 2-Temporal and spatial rainfall data analysis; 3-Stream flow and hydrograph analysis; 4Modeling with WMS and/or NSPECT and/or AnnAGNPS; 5-Sensitivity analysis and “What if” type of questions; 6Effect of land use changes on water shed in leeward and windward conditions.
