Abstract: The present study was carried out to determine the physicochemical characteristics of water and sediment and the textural aspects of sediments in western mangroves of Kachchh-Gujarat, west coast of India, for a period of two years during 1999-2000. Surface water and sediment temperatures varied from 17oC to 37oC and from 18.4oC to 37oC respectively. Tidal amplitude varied from 0.03m to 3.78 m. Salinity varied from 34.0 to 44 ? and the pH in water and sediment ranged between 7.0 and 8.9 and 6.29 and 8.45 respectively. Variation in dissolved oxygen content was from 3.42 to 5.85 ml l-1. Concentrations of nutrients viz. nitrate (0.23 to 7.26 ?M), nitrite (0.04 to 0.87?M), phosphate (0.13 to 3.12 ?M) and reactive silicate (4.23 to 19.02 ?M) also varied independently. Total organic carbon varied from 0.29% to 2.56% and the total inorganic phosphorus ranged between 0.12 mg g-1 and 1.97 mg g-1. Total nitrogen varied from 0.02 mg g-1 to 1.95 mg g-1. Sediment textures ranges in terms of % of sand, clay and silt were: 0.26-19.2; 7.6-47 and 47-87.4 respectively in all the 3 stations. The nature of soil texture is characterized by the abundance of silty loam, silty clay and silty clay loam.??
