Introduction

Watershed

“ is the land from which water drains into a particular stream, river, lake or other water body.”

All land (and all humans, wildlife, and activity on that land) are part of one watershed or another.

Watershed Management

Watershed Management

“is land management and restoration as it is about the river itself. Protecting and restoring rivers entails addressing pollution and wildlife habitat problems in the entire watershed, or the entire land area that drains to the river.”

Principles of Watershed Management

Utilizing the land based on its capability. Protecting top fertile soils Minimizing silting up of tanks,reserviors and

lower fertile land In situ conservation of rain water Protecting vegetative cover throughout the year Water harvesting for supplemental irrigation Maximizing form income Improving infrastructural facilities for

storage ,transport and Agri.marketing.

Objectives of Watershed Management

Efficient use of land Flood control Adequate water supply Efficient use of natural resources Expansion of recreation facility

Steps in Watershed Management

Basic Information Statistics of population and livestock Pattern of land ownership Topography Cropping System and Yield and land

capability for farmer Data on Rainfall, Erosion problems and ground

water Information on existing water resources Service faculties like school, banks ,Market

health,Veternary facilities

Developmental Components

Soil Conservation Measures Runoff Harvest in storage structures and its recycling

for protective irrigation. Improving fuel, fodder and horticulture through

alternate land use systems Optimal land use with appropriate technology Ground water recharge and development Efficient use of available water Development of livesotck,poltry and other associated

activities

WATERSHED 2005 MANAGEMENT CONFERENCE.

The 2005 Watershed Management Conference, "Managing Watersheds for Human and Natural Impacts: Engineering, Ecological, and Economic Challenges" is sponsored by the Environmental and Water Resources Institute (EWRI) of the American Society of Civil Engineers (ASCE). This was the ninth in a series of specialty conferences focused on watershed management. The conference was first held in Billings, Montana, in 1965 and has been repeated every five years since. This year's conference will be held east of the Mississippi River, where the problems and challenges of urbanization and sprawl are particularly acute.

Conference Topics

Stream and Watershed Restoration, Constructed Wetlands, and Best Management Practices

Modeling and Monitoring of Hydrologic Processes: Rainfall-Runoff, Snowmelt, ET, Infiltration, and Other Phenomena

Effects of Fire and Post-Fire Mitigation on Watershed Hydrology Managing Watersheds for Control of Ecological Impacts Groundwater: Competing Demands, Contamination, Recharge,

Mining, Salt Water Intrusion, and Other Challenges The Economics of Watershed Management: Government Policy

and Smart Growth Managing Forested Watersheds: Roads, Fish Habitat, Stochastic

Disturbances, and Other Challenges
