Chapter Objectives

• To manage and control the plan on broad area of water resource.

• To describe the methods and problem of planer management.

Key Term

• Implement: To practices or manage the plan into operation

• Spatial : the broad area or whole size of area

• Watersheds: The main sources of water the flow from high ground or

mountain to the lowest ground or river.

• watershed restoration project: is the project on in-channel work, road and

culvert reconstruction, and riparian restoration through silviculture.

• Assessment: judge or decide the amount, value, quality or

importance of something, or the judgment or decision that is made.

• Feasible alternative: is an activities schedule that achieves the

goals of the plan.

Introduction • Watersheds are recognized as an important spatial

unit for planning because it is the bridge between strategic plans and site-specific project plans.

• Spatial planning in watersheds requires three elements:– An assessment of the current situation – A statement of goals for the watershed linked to

forest-wide objectives.– The initiation of watershed restoration projects.

Watershed Assessment

• Assessments are a component of watershed planning that provide a systematic procedure for characterizing a watershed and ecological characteristics.

• Object of Assessments:- Define the existing condition of a

watershed- Define the structure and

processes in a watershed and their linkage to management activities.

- Stratify land by environmental effect.

Watershed Assessment

• Assessments provide information on active processes in watershed include:– Landslides, – debris floods– Current conditions of uplands and riparian areas– How the factors influence riparian and in-channel habitat.– Gather data for design management alternatives.

Problem Description

• Plan management must ensure to provide opportunities to review future effects of current management action.

• Plan must be considered and protect for wildlife, fisheries, soils, and other ecological concern.

• Watershed plan project must be determined on its activities such as stream crossing by roads, buffer widths along streams, the location of cable ways across riparian zones, the size and distribute of harvest units.

• Planers must to determine on environment and economic effect.

Generation of alternatives

•Feasible alternative is an activities schedule that achieves the goals of the watershed planning.•Feasible alternative provides two functions:

- It provide planners with option that can be weighted with factors that are difficult to quantify.

- It can help identify the most efficient way to meet goals.

• Spatial and Temporal Relationships

– A specific requirement of tactical plans is that they contain sufficient spatial and temporal detail to define when and where the polygons will be treated relative to key ecological, social, and economic variable.

• Linking Goals and Activities

– One of the most important aspects of implementing spatial planning in watershed is relating ecological goals to management activities.

– Ecological goals require:• Control of Max & Min treatment area • Control of re-entry periods• Control rate

Analysis• The management alternative has two

technologies that planers need to use for observed on incorporate the spatial and temporal relationship:– GISs (Polygons to show: slope class(high, medium,

low); visual class (foreground, background); risk class(high and low risk soil)

– Spatial and temporal based decision model.

Conclusion

• The implementing spatial planning in watershed is very important for managing and controlling our water resource in order to support life cycle of all organisms and stable natural evolution.
