The purpose of this project is to improve our understanding of how forest harvest, road patterns, and climate change will impact water flow in watersheds that span the transient snow zone. The objectives are to use extensive field measurements and computer models to accurately simulate flow changes resulting from harvest practices.
Hydrologic variables used in this assessment include water table level, drainage, and storm flow on different spatial and temporal scales. Wetland ecosystems have higher water storage capacity and higher evapotranspiration than uplands. Hydrologic impacts of forest management are variable, but generally minor, especially.
The hypothesis to be tested quantitatively in this research project is that timber harvesting can impact hydrologic response. To test this hypothesis, a physically based numerical simulation approach will be employed to characterize quantitatively surface and near-surface hydrologic response in a forested watershed.

Reduction in forest cover, through timber harvesting, for example, can increase streamflow in the short term. These increases in water yield are generally not sustained over the long-term, however; any increases in water yield are most likely to occur during.

In hydrology, routing is a technique used to predict the changes in shape of a hydrograph as water moves through a river channel or a reservoir. In flood forecasting, hydrologists may want to know how a short burst of intense rain in an area upstream of a city will change as it reaches the city.
We used the model to simulate the effects of three different land use scenarios (100% old-growth, 100% clearcut harvest, and present-day land cover consisting of 45% old-growth and 55% harvested) on trade-offs among five ecosystem services: timber production, carbon sequestration, greenhouse gas regulation, water quantity, and water quality.

These sources are geographic data, yield tables, economic assumptions such as management costs, timber prices and discount rate, and mathematical representations for policy and law represented by actions and constraints.
A watershed hydrology model was developed using hspf (hydrological simulation program – fortran) to model existing conditions and simulate the hydrologic impact of potential land use changes. Several scenarios were simulated including pre-settlement conditions, various timber harvesting practices, forest restoration, and wetlands conversion.
Long-term (15 years) simulation was conducted to evaluate the hydrologic impacts at different stages of stand mtation. This simulation study concludes that for- est harvesting has substantial eftects on hydmlogy during dry peri- ods and clear cutting of both wetlands and uplands haa greater.
