ENVIRONMENTAL IMPACT ASSESSMENT ON DAL LAKE SRINAGAR KASHMIR Afreena Bano - M. Tech Environmental Engineering, IIMT University Meerut (U.P.) Saurabh Kumar Soni -H.O.D, Civil Department, IIMT University Meerut (U.P.) -----------------------------------------------------------------------***--------------------------------------------------------------------ABSTRACT: Dal lake is known as “liquid heart’’ of Kashmir which is summer capital of Jammu and Kashmir .Dal lake’s ecologically is getting polluted day by day in fact dying day by day by the human activities. The present paper summarises the conservation measures taken to retrieve the pristine glory of the lake with an attempt to put forth the environmental impact assessment studies of the various measures viz. catchment treatment, silt and sedimentation Control, wastewater management, weed infestation, improvement in lake hydrology, combatting algal blooms and solid waste management.
KEY WORDS: EIA, Catchment. weed infestation, hydrology, blooms ,physio-chemical characteristics ,floating gardens, soil erosion.
INTRODUCTION: Catchment administration by way of rebuilding of degraded forests, through manors form, hedgerow
and in situ moisture preservation, waste line treatment through properly planned check dams, RCC structures, retards ,gabion stone dividers, trenching etc. other than scrounge production through silvi pasture advancement and on cultivate development. Siltation and sedimentation control measures by way of construction of settling bowl on the section of lasting water source (TELBAL NALLAH) into Dal Lake counting intake structures, diverting goads, backwater bunds and RCC Deck Bridge.
b)
Algal sprout control measures were taken by bubbling pure oxygen into contaminated waters through coasting aerators.
c)
Houseboat sanitation through realignment and relocation of houseboats and connect alia interfacing to primary sewer system.
d)
Solid Waste management; The solid waste management in human settlements within the lake (more than 50,000 souls plus 10,000 persons in boats) is one of the contributing factors of the lake environment and thus are managed through garbage bins and the door to door collection including houseboats and the final disposal is being done by Srinagar Municipality.
e)
The Dal Lake is of incredible visitor and financial significance for the individuals of the Kashmir valley. The Dal Lake which has contracted in measurements, from 25 sq. km in past century to less than 11 sq. km presently is battling a loosing fight against wild contamination and sedimentation. As a pilot consider, the Dal Lake watershed spread over an region of 337 sq. km was taken up for soil disintegration consider utilizing remotely detected information, GIS and reenactment modelling . The ponder utilized distinctive sorts of information counting Overview of India topographic maps for producing DEM of 40 meter determination, soil outline, Landsat TM & ETM adj. information and the field perceptions. Two date Landsat picture, 1992 and 2001, were utilized for creating the arrive use/land cover outline of the study zone and to identify the changes between these two time periods.
