Object Watershed Link Simulation (OWLS) is a physically based watershed model. In the OWLS
model, a watershed is defined as a three-dimensional object with linkages between cells and their
attributes (e.g., area, slope, soil type, etc.). A cell is defined as the linkages of edges and their attributes
(e.g., length,...
A method for delineating watersheds by computer using digital
elevation model (OEM) data is presented. The five steps in this
process are detailed and examples are shown. The algorithm was tested
using a manually created OEM for a small area in Northern
California. Three basins were delineated using the delineation...
A hybrid landscape optimization/simulation model called SafeD (Simulation and analysis of forests with episodic Disturbances) was built to address the needs of forest management planning in the Applegate River Watershed, southwestern Oregon (the Apple gate Project). There are two goals of the Applegate Project: 1) search for forest policies and...
The Wood River Basin lies upstream of Upper Klamath Lake, the main reservoir of the USBR Klamath Irrigation Project that provides irrigation water to 210,000 acres of downstream land. Water allocation became a contentious issue in 2001 when drought led to curtailment of irrigation deliveries to the Klamath Irrigation Project...
A stand level model, PREscription generator under Multiple Objectives (PREMO) was built to generate prescriptions that address multiple objectives for management of the forests of the Applegate River Watershed. PREMO is a part of the landscape model of the Applegate River Watershed Forest Simulation Project and generates prescription choices for...
Degradation of watersheds is a major concern in areas where adverse climate effects and unsustainable use of the natural resources have caused extensive stresses to watershed systems (e.g., increased floods, increased droughts, worsened in-stream water quality) through the years. While considerable efforts are being made to generate technical solutions that...
With the success of the CounterDataFlow Pipeline microarchitecture developed by Oregon State University, there is increasing demand for a highly flexible high-level simulator modeling tool to support the further expansions and studies of the Counterflow pipeline processors family. This work examines the implementation of a Java-based execution-driven simulator modeling tool,...
Fuel management has been used as an effective local strategy to reduce the undesirable consequences of wildfires. Many efforts toward scheduling of fuel management activities across a broader landscape have been proposed, with the hope of achieving larger landscape-scale management effects. However, scheduling of fuel management treatments across the broader...
The Walla Walla basin lies in an arid region of Eastern Washington and Oregon. A large portion of the area is devoted to agricultural production, relying on irrigation water diverted from the Walla Walla River and underlying aquifers occurring within Quaternary and Mio-pliocene era gravel deposits, as well as a...
