The objective of this project is to assess the significant changes in land-use and land-cover that have occurred within the headwaters region of the Rio Conchos watershed using satellite data and to conduct a one-time water quality survey of the river. The information derived from this study will serve as a temporal benchmark to which future changes in land-use, land-cover and water quality conditions are compared and quantified.
This study utilizes Landsat Multispectral Scanner (MSS) and Landsat Thematic Mapper (TM) data from several different time periods to delinate how much woodland, agricultural land and grassland was lost to logging in the headwaters region of the watershed. The time periods of interest are 1980, 1992 and 1997. The use of multiple Landsat (land satellite) images permits us to measure and analyze the continuous change in vegetation coverage within the study area over an extended period of time. This project also involves the analyses of in-situ geochemistry data collected during a one-time water quality survey of the Rio Conchos. The water quality information should serve as baseline information for long-term environmental monitoring of an important and often neglected river system. This study has implications on both sides of the United States and Mexican border.
